Dream Dollhouse

Build a three story dream dollhouse perfect for 12" dolls with these free easy step by step do it yourself dollhouse plans! Inspired by the KidKraft So Chic dollhouse, this do it yourself version is made of soy based plywood and finished with non toxic linseed oil.


Projects built from this plan. Thank you for submitting brag posts, it's appreciated by all!


Author Notes: 

Okay, you know that feeling, right before you go to bed on Christmas Eve, all the gifts wrapped, everything is perfect, and you are exhausted ... but you still can't sleep. Because you are just so excited to wake up and see the happy faces of your family enjoying Christmas morning. 

Been there?
I sort of feel that way right now. I am so excited to share this plan with you! 
So we've over the years built more furniture than I can count.  You would think I'd be over the "I can't believe I made that!" stage.  You would think.
Well, I'm apparently not.  I find myself wanting to just stare at it, smiling as I walk by it.  This building thing ... it is amazing.  
One sheet of PureBond plywood in Birch (yes, this dollhouse is made of formaldehyde free soy adhesive plywood!), seven pine 2x2s and some boiled linseed oil (can you believe this dollhouse is finished with oil extracted from flax seeds?), some scrapbooking paper and a quart of pink paint for accessories, and we've got an eco-friendly dollhouse that will outlast childhood.  This dollhouse is STRONG.  Like three kids can climb on it strong.  
And did I mention she rolls?
For the wallpaper, I simply decoupaged scrappbooking paper to each "room."  Quick and easy.  For the roof, I took scrap pieces of 1/4" plywood cut into 5" strips and cut scallops out with a jigsaw (just use a small round object to create your pattern with) and nailed the strips down.
For the stairs, I simply cut 19 1x2s to the width of the stairs, and glued and nailed them on top of each other.  Couldn't think of an easier way to do that!
And the furniture ...
The furniture shown in these photos was actually borrowed from my niece's dollhouse.  Just haven't quite had the chance to make furniture yet.
Will you help me?
I will of course be adding plans for doll furniture.  But because a dollhouse of this size could use 100 or more pieces of furniture before it starts to feel like a dollhome, I'm asking you to help me in creating miniature furniture plans.  If we all work together, we can make very special Christmas mornings everywhere!
Just make sure you select "Dream Dollhouse" on the Collection dropdown so your plan will show up on the Dollhouse page.  I can't wait to see (and build) your plans!
But first, we gotta build this dollhouse!
Shopping List: 

1 - sheet 3/4" PureBond Plywood
7 - 2x2 @ 8 feet long
1/4" plywood scraps for roof
2 - 1x2 @ 8 feet long for stairs
4 - 2" caster wheels and screws for 3/4" stock
use either 3" screws or 2 1/2" pocket hole screws, depending on your joinery technique

3 inch screws
1 1/4 inch finish nails
120 grit sandpaper
paint brush
measuring tape
hammer (can be substituted for brad nailer with a nail punch)
safety glasses
hearing protection
General Instructions: 

Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!

Warning - this dollhouse is HUGE! Measure your doorways to make sure it will roll through doorways.
Cut List: 

7 - 2x2 @ 32"
6 - 2x2 @ 24"
4 - 2x2 @ (Both ends cut at 30 degrees off square, ends are NOT parallel, long point measurement)
4 - 2x2 @ 37 5/8" (One end cut at 30 degrees off square, long point measurement)
Plywood cut to diagram

Step 1: 

Have your home improvement center rip your plywood into a strip 24" wide and a strip 13 1/2" wide as shown in diagram. Then all you have to do is make the crosscuts.

NOTE: I really considered using 1/4" plywood for the floors, but wanted to create a dollhouse that would last and last - and could even be used as a bookshelf later on. The 1/4" plywood is just too flimsy for that. Then I considered 1/2", but the price difference between 1/2" and 3/4" is only a few bucks, and 3/4" is just so much easier to work with because you have a wider area to work with. Of course you can modify this plan - if you made this dollhouse with 1/4" plywood, it would be CHEAP to make ... like $30 cheap.

Step 2 Instructions: 

Build the ends as shown above. You can use a countersink bit and 3" screws or the Kreg Jig and 1 1/2" pocket holes and 2 1/2 pocket hole screws. For the angled joints, just clamp, glue and predrill holes with a countersink bit. I only used one screw (and alot of glue) for each joint to avoid splitting the wood.

Build two, make sure they match up.
Step 3 Instructions: 

Now just join the two sides with the longer 2x2s.  This is easy stuff.  Just make sure that the top 2x2 is exactly 13 1/2" above the top story 2x2 - this does matter.

Step 4 Instructions: 

I used pocket holes set for 3/4" stock and 1 1/4" pocket hole screws drilled on all sides of the plywood to secure to the frame. If you do not have a pocket hole jig, you can cut corner braces out of scrap 1x2s and fasten, or countersink (very carefully) long screws into the edges of the plywood.

Step 5 Instructions: 

Now build your interior walls. You can use a shorter screw or even nails here - just don't forget the glue!

Step 6 Instructions: 

Cut stair openings out as shown in diagram and place 2nd story shelf as you did bottom story shelf.

Step 7 Instructions: 

Add the bottom story walls. I used pocket holes, but you can also use nails here. TIP: Offset the walls between stories a tad so you have a spot to nail if you are using nails.

Step 8 Instructions: 

Add the top story as you did the lower two stories.

Step 9 Instructions: 

Followed by the middle story interior wall.

Step 10 Instructions: 

Finally, add the top story interior walls system.

Step 11: 

Stairs are built by stacking 1x2 boards staggered as shown above. Be very careful when nailing and use lots of glue.

Step 12: 

I then simply decoupaged the interior walls with contrasting scrapbooking paper. The roof is simply strips of 1/4" plywood - you could use 1/4" hobby stock as well - cut with a scalloped shape, lapped and nailed down.

Step 13: 

Attach 2" caster wheels to the 3/4" plywood base so wheels can swivel easily.

Preparation Instructions: 
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth. It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

JUST a few hours ago I was scouring the web and your blog for an easy DIY dollhouse for my daughter. No offense to most of the others out there, but they're all so gawdy and over the top. I wanted something a little more classic looking and this is perfect. I'm planning on making this for my daughter for Christmas and I'll be able to completely customize every last decoration thanks to you. You're the best!!!

Decoupage is when the paper is glued to the surface of the wood and then completely coated with a top coat of a clear glue which dries to a protective coating. Mod Podge is the popular decoupage product these days. When I was younger we just used a watered down form of Elmer's White Glue because it dries clear.

Decoupaged = Glued on with diluted white (Elmers) craft glue and water. Sealed on with another coat.

It might be easiest to mark the floor levels and wallpaper the walls before assembly.

I'm decorating the walls now. I have to say I think it's easier once the walls are nailed together, but before you assemble the floors. After I decorated one side of the walls, I realized that I would eventually have to nail through the paper and leave a mark! So I would suggest building the walls, and then decorating, and then assembling the floors. Good luck!

Ana, you amaze me. I was going to do a dollhouse for my small human's third birthday, but ran out of time and just sewed a quick (robot!) cape instead. Was giving some serious thought to just buying her one for Christmas 'cause I couldn't find or make any plans I actually liked, but here you are...

Also, the stairs are *ingenious*, but thinking of cutting and nailing and gluing so many tiny pieces is kinda doing my head in a little. :)

I'm so glad we have little girls around the same age. Every new project you post I absolutely adore and usually have been thinking about buying. I'm so glad you posted this in time for building it before Christmas! Your decorative touches are super adorable. What a great project, but now what can I build for my son? hmmmmmmmm, we'll see.

Thanks Ana, once again, you've impressed and inspired.

I was JUST looking at the KidKraft version online a few days ago! Yours totally looks store-bought (better actually!). My daughter already has a KidKraft doll house, but I love that this has three floors and is double sided - even if it is huge!

I'm thinking I have an unused set of Jenga type blocks that would work for the stairs...if there's enough.

Love, love, love the scrapbook paper wallpaper - looks awesome!

For accessories, we totally need a toilet plan! My 6 year old complains that hers is just a picture on the wall. :)

My 4 year old daughter would LOVE a barn for this to put her animals in. This is going to be a year long project for me (for next Christmas) and would love to have a barn to go with it) :)

I was prepared to think about spending around $200 for my daughter's Christmas present. You have totally ROCKED my world this morning and I don't know how to thank you. I honestly don't know what to say!

first thing I think is "darn,I have my gift already for my little girl,but this would make a cool BatCave for the boys" I'm hopping I can talk my husband in to making this as a Batcave or something and just paint it darker and the boys can use it for all there little action figyers. I'd have loved to have a dall house like this growing up.

It would be so cool to make it as if it is Bruce wayne's mansion - have the top two floors be a "normal" house, and the bottom floor a bat cave with a fire pole instead of stairs!

I remember my Barbie dream house had an elevator. I wonder if we could rig one up some how? I love this. My son loves his Playmobile doll house, but the pieces are just too small. We also just had a daughter and I wanted to build something they both could play with in the coming years. Perfect.

I have also been hunting for plans for a sturdy doll house, so Ana you are a Christmas miracle. I'm thinking maybe my son would like one made into a firehouse/police station. Some upstairs sleeping quarters, a pole instead of stairs and a place for the cars on the bottom. Even add a jail cell if doing a police station.

Thanks again Ana!

If I could make a suggestion for the staircase? My dad showed me an easier and faster way to build stairs out of a single 2x4 that I loved (I say this because I should point out that I didn't think of this myself). It's also a little stronger to stand up to a child beating on it.

If you have a tiltable miter saw or circular saw:
Tilt the blade at a 45 degree angle and cut along the 2x4 to make the front of the stairs. Then turn the board around and cut the other direction to make the tops. The end board, if you lay it down, will be flat on the bottom but look like triangles (or teeth) on the top. Tip up and nail it in for instant stairs.

There's a picture of his staircase here:

Also, if you want a chandelier in your dollhouse you can use layered mirror clips (the little clear flower things) and an eyelet screw to make a chandelier really quickly. There's a picture of it on the same link.

Again you came up with awesome plans! Is there any way to make the floors separately and then be able to put it together? I would like to have DH make this for one of our grand kids but since it's so large and heavy shipping it to South Carolina from SoCal is out of the question. :-)

This is the most adorable dollhouse I've ever seen. You did an awesome job! i love your blog!

What about a barn/batman mansion on one side and a more girly side on the other? (For those that want to do something for boys.)

Ana, this is amazing! And yes, I like so many others am totally making this for Christmas. Thanks so much!!! (I didn't even know the other existed and I LOVE this one!) Yay Yay!!

YOU are amazing. Thanks again!

This is hardly a furniture *plan*, but as a kid, I used wooden thread spools as table bases and stools for the dollhouse at my babysitter's home. I would glue a larger circle of balsa on top of a larger one for a nice pedestal table, etc. Craft stores also sell very small wooden flower pots that would be good for lamp shades if turned upside down and placed on dowels w/ a little base, like the standing lamp in your pictures.

For those that are looking for dollhouse furnishing ideas, here are a few:

I made Ana's other dollhouse last Christmas but modified it to fit Barbies. For those that wonder what "decoupage" looks like, I decoupaged scrapbook paper onto the floors and walls to act as tile, rugs, and wallpaper. You can see that project here:

Also, http://myfroggystuff.blogspot.com/ is a blog dedicated to Barbie DIY! She has lots of cute ideas, like a TV, wall clock, a laundry room, bathroom, mailbox, kitchen, and even a sofa! They're all made from RECYCLED materials in her own home, but always turn out looking ADORABLE!

I use http://www.printmini.com/printables/pp.shtml for miniature printable items, like Barbie sized posters, books, magazines, assorted food boxes, and even a passport and laptop! Just print, fold, and tape or glue. I took the wall posters to my local teacher's supply store and had them laminated (just under $1) to help them last longer.

Hope that helps to liven up the creative spirit! :)

I love this dollhouse, but have no idea where to put it....may have to get creative! I just finished a barbie camper that I made for my daughter's birthday, and I compketely furnished it. Chairs and couches can easily be made with leftover scraps of 2x2 and small pieces of plywood, then just make little slipcovers for them and they would be perfect. And I never did come up with a toilet....ended up buying the barbie i can be babysitter that had a toilet, sink and two barbies fo $12. I will try to post plans for all soon! And i LOVE this dollhouse!

I so want to build this for my munchkin for Christmas!! BUT I gotta say that the selection of 2x2 furring strips at the local Blue and Orange stores never look as good as the ones you use Ana!! They are always so knotty and crooked. I love the natural look on the wood but I always have to use so much wood filler on the furring strips I've used on projects... but they've all been painted afterwards. Do you think I'd have better luck finding nicer ones at a lumber yard?

I have the same issue with 2x2. The ones kept indoors seem to be the worst. If you have access to a table saw you can create your own by ripping them down the middle and they are STRAIGHT!

I have a little boy and a little girl that I would love to build this for Christmas! I LOVE that some of you have suggested a Bat Cave for the boys - mine would go nuts over it! Now to do a little research for what the inside of the mansion would look like. Hmmmm.... Can't wait to see some of yours for inspiration!

I am building this for my niece for Christmas, right after I finish my Farmhouse Table.
I was wondering how I could build little drawers or 1 larger drawer underneath it?
I don't think adding a couple of inches to the heigh would make a big difference, but it might make mom very happy to have that storage space.

A box underneath for storing dolls and furniture would be great.

Make a 3/4 plywood box under the house, for an elevated base, using the bottom floor as the top of the box. Put the wheels on the base. Add drawers to the box.

This would mean cutting one more "floor", and the sides of the storage part, then whatever you need for the drawers. I'm lazy, so I would probably make the box tall enough to stick plastic drawers from the housewares department into and call it good.



Hi Ana,

The dollhouse is really cute, and has something I find very important in dollhouses....stairs! I dislike having to pretend there are stairs in our Playmobil structures. I mean to include one someday in this dollhouse I built from scrap material for my daughter, but haven't gotten around to it yet!

I also really like the ability for your dollhouse to be played with from more than one side. I did that with my daughter's as well. It is very open. Here's the link to it, and it was also featured in Ohdeedoh this summer!


I am glad to have found your website today via Ohdeedoh and look forward to sitting down and peeking around in it!

corner blog

Perhaps if you'd read the post you'd have seen where she mentions that this dollhouse was inspired by KidKraft's So Chic dollhouse.
This blog was, after all, originally titled Knock-off Wood.

True, but I believe she admits this. And, that one goes for $200! I built mine for under $100, and had so much fun doing it. My daughter loved watching me build it, and that is worth so much more than money!

For stairs I was wondering if you could just take dominos and glue them together rather than all of that cutting. Might give it a try! love the dollhouse...it is like the So Chic but a heck of a lot cheaper to make it yourself! And more fun!

Went ahead and bought the furniture...after seeing an actual photo of our dollhouse in progress, I don't think it will be a problem to fit. This house is so much bigger than your photo makes it seem. LOL I've got to make room!

Building one for my granddaughters. And raising them the way I was raised I know in my heart that this dollhouse built by ME will mean more to them later than anything made overseas by slave labor. Hats off to you Ana. You helped alot of people make life a little better by sharing this.

Thanks everyone, yes, this dollhouse is most definitely inspired by the Kid Kraft So Chic dollhouse .... that was most likely inspired by the Voila Dollhouse ...

Which was then inspired by ... and so on.  We all find inspiration from somewhere, and I'm happy to help those that want to handmake furniture because they either cannot afford to buy it, refuse to support poor labor standards, are supporting local lumber mills, or want to paint or finish the projects with healthier alternatives, just to name a few amazing reasons why DIY rocks.  BLB!

Hi Ana!

Thank you so much for the plans!
My husband and I are about to build two of these for our girls and we just realized we are missing a few pieces because they were not on the cut list.

The 15 5/8th pieces that make up part of the roof.
We didn't notice until now as we are about to put it together.

Thanks again! :)

Hi There,

I was wondering if you tried to estimate what would be the total cost of building and assembling the entire So Chic inspired dollhouse considering similar quality of wood, paint and preserving the same safety standards. That would be interesting to know.
Best regards,

What a great set of plans! Full assembly within four hours. Just did a final sanding and my wife is very excited for Christmas to give this to our little girl.
ROOF CONSTRUCTION: I used a scrap piece of beadboard which I cut as a two-pcs roof section, one for each side. Gives the appearance of the steel roof structure and saves even more time.
Thanks for a great set of plans!

After some experimentation today I discovered the perfect formula for using pocket holes on the 30 degree angled joints. Set your pocket hole jig for 1 1/4" stock and use 2" pocket hole screws. Worked perfect!

Thanks Ana for the wonderful plan. My daughter will be so excited to get this on Christmas morning!

While I really appreciated the guidance, these settings didn't quite work for me; the 2" screw ended up being too long and piercing through to the other side. I played around with some scrap, and these settings worked best for me:

bit collar set at 1"
hole guide set at 1 1/4"
using 1 1/2" screw

I just thought I'd comment in the case that someone else was also experiencing this problem. Well, back to building... Christmas is soon approaching!

$40 for the wood, screws and glue. Alot more on a new sawblade, sandpaper disks, claps, kreg jr, modge podg, scrapbook paper and paint.
But hey now my workshop is stocked.

I think i could mave dne it for close to $50 but i decided if i was gonna spend the time I should do it nice.

I spent about $70 on lumber, went ahead and bought the cheaper pocket jib for $20, and then my wife spent $10-$20 on decorating materials and paint.

This plan is wonderful, I am about to start building this for my daughter and I can't wait until she sees it. Two questions though, I am a first time Kreg Jig user and if I use the 1/2" plywood instead of the 3/4" do I need different sized screws? Please help, I don't want to screw this up (pun kind of intended). Also, can I use 1X2s or 1X1s for the supports instead of 2x2s - they seem so bulky. Please help!

I was thinking I needed 2x2 Pine boards, which are pretty heavy but I just realized they are furring strips which are much lighter. Now, I just need to find some decent ones that are straight and smoother. And I think I have the Kreg Jig situation under control.

It looks like you didn't give the measurement for the 2x2s used to create the roof:

4 - 2x2 @ (Both ends cut at 30 degrees off square, ends are NOT parallel, long point measurement)

So I went to get all the wood for making the dollhouse yesterday. I got Orange to rip the plywood so all I would have to do is make the crosscuts. The problem I had was when I got ready to make the crosscuts with the diagram and realized the measurements for the 32 x24 inch pieces didn't take into account the width of the saw blade. So I had to change the measurements for all the 32 inch 2 by 2s to match the width of the floors. Mine are 31 7/8. I’m surprised no one has come across this issue. Am I missing something? And thanks Christine to all for mentioning the missed measurement for the roof.

I love these plans and hope to be able to make one for my kids, but when I saw the picture of the Voila house, it reminded me of one I used to see in the backs of comic books (I grew up in the 70s but also had some of my mom's older comics so I don't know exactly which ones they were in). It was a fairly large dollhouse also, but it was two sides that met in the middle, and there was a space open in the middle that a child could sit in and close the house around herself (or himself, I guess). I always thought it would be wonderful to get in it and shut myself away from my brother. ;-) Now I just wonder if anyone else has ever seen this dollhouse or know of plans for one like it? I've thought about sketching out plans for it myself, but have never gotten around to it. For now I'd be happy knowing I wasn't imagining things back then. Thanks!

I was wondering if you could provide the link to accessing the plans for all the components for this dollhouse? thank you sooo much!

I spent $40 on plywood (but only needed half, so used the other half for something else). Probably $10 on 2x2. About $20 on paint and craft paper. And another $10 on wood to make furniture. Not too bad!!!!!

But I thought I just read That boiled linseed oil is dangerous for kids, and you should only use raw linseed oil. Boiled has petroleum products in it.

Boiled linseed oil is indeed very dangerous for kids, so don't put it in their sippy cup. And that's the quantities you'd have to consume to make it dangerous. I'm not aware of petroleum products in BLO, but it does contain metal salts, and metal salts are unhealthy to have build up in your blood (think lead poisoning).

Once the finish is dry to the touch, the metals are trapped in the oil, and can't get free. Usually 24 to 48 hours is sufficient. Once the metals can't get out, it's about as dangerous as metal eating utensils.

The bigger risk is fire. The rag used to apply BLO generates heat during the cure process, and if the heat can't escape you'll get a fire. Spread the rags out to dry a single layer deep, and don't chuck them in the trash until they've had a day or so.

Just for future reference, none of the finishes available at a woodworking store or home center are dangerous for kids once they're cured. All of them are bad for adults when consumed in their uncured form. Some of them, such as shellac, are common food ingredients. If you ever see shiny candy or pills, that's a layer of dewaxed shellac making it shiny.

I live in Singapore where the apartments are rather small I love this doll house but due to the large size wish it was foldable into one box which can fit under the bed so that my girls can play when they want and put it away when not in use. Hope some one comes with a plan to use for me. Thanks

You are so amazing. You make these projects simple enough for anyone. I cannoe=t wait to start this dollhouse for my granddaughter. Thank you so much for all you do!

High, in the directions it says to cut one end of the 37 5/8 inch 2x2's 30 degrees off square. It also says to cut the 15 5/8 inch 2x2's at 30 degrees off square. My miter chop saw has the marking at 22.5 for that cut. However, when I line the long boards up with the shorter ones, they don't meet to make straight walls for the house. What am i missing here? I know i'm a novice and terrible with angle math, so I'm thankful for any "Angles for Dummies" advice. please help.

When you cut the roof frame 2x2's and long wall pieces ALL 30 degrees off square, it is NOT working for me. Can someone explain these angles cuts in layman terms? Any help is greatly appreciated!

what scale can the furniture be for this doll house.i am making one for my daughter for christmas

My daughter would have been fine with the stairs, but her 3 boys would have probably broken them over time :(.

So, I thought about the stairs out of a single 2x4, but I was afraid it would look half baked, plus I don't have a miter saw.

So, what I did instead was keep the 4 inch width, cut my stairs 3 inches width, and found some half inch strips of plywood for the sides. Basically I made rails. I glued all the stairs first, put the one at the top pointing up instead of out (to attach to structure), and then cut/glued the rails on the side. They go all the way down, and are 2 inches wide so it makes a good size rail. Once I glued those one and used my nail gun to solidify, it was strong as ever, and it looks very nice. I used small nails and put one on each stair, both sides, all the way down. Very sturdy. Took a little more time, but looks nicer, is stronger, and best of all my wife and daughter love it! What else matters? :)


My husband is currently building this adorable dollhouse for our 2 girls. Ana, what furniture is pictured in yours? Did you make that? Would the Fisher Price Loving Family dollhouse furniture fit? Just want to make sure that the furniture wouldn't be dwarfed, since this dollhouse is HUGE!


Hi! I want to make this dollhouse for my munchkin for Christmas and I'd like to get started on furniture for it soon. Did there end up ever being any plans for furniture?

Jess Keenan

I am desperately trying to find a cost effective way to build an American Girl doll house. This would work great if it didn't have the center walls and the floors were further apart. I need about 20" between shelves and between 18"-24" for each floor. Does anyone have another plan for a fairly beginner?

I am have trouble with placement of the pocketholes. On the two sides I did pocketholes at the bottom and attached to the vertical pieces with no problem. How do you place the screws so they don't hit each other when connecting the front pieces? All the pieces are 2 x 2's. Also, I'm using 1/2" plywood for the 3 levels and it seems like pocketholes would be too big for that size thickness. I am beginner and would appreciate any advice on this. Thanks.

Hi everyone! i'm trying to build the dream doll house for my daughter but the only part i'm haveing trouble with is makeing the outside part before you put the floors i don't understand what 2x2 means how wide and thick do i make each of them can somebody who already made this doll house Please help me!! i really need it Thanks.
