Step 1

Window Framing
So this is not how you would frame a window in a real house, but because our walls are only 4′ tall and we’re just building a little playhouse, this will be plenty strong. And despite the way the frame looks, the load bearing walls are actually the side walls. Use the 2 1/2″ screws and glue to fasten the studs to the window frame.

Step 2

Wall Framing
Now add the top and bottom plates to the window studs, and also screw the end studs to the top and bottom plates. Use 2 1/2″ screws and glue.

Step 3

Cut your rafters by mitering the ends at 45 degrees. Then use 2 1/2″ glue and nails to fasten the rafters together and to the wall as shown above.

Step 4

Cut out the sheathing as shown above. Refer to the dimensional diagram for window cutout dimensions. Fasten the sheathing to the studs using 1 1/2″ fasteners and glue.

Step 5

Step 6

I ended up using 1x2s for the window trim because I felt like when the window itself is put in, the frame will be quite thick. Use the measurements above to guild you when trimming out the gable ends for the playhouse.

4 – 1×2 @ 17″
4 – 1×2@ 18″
4 – 1×3 @ 48″
4 – 1×3 @ 43″
4 – 1×3 @ 34″ (Both ends mitered down 45 degrees)

You will need to in addition to the above cut list purchase (to trim out 2 gable end walls)
2 – 1x2s
6 – 1x3s

Finishing Instructions
Preparation Instructions

Yay! As always, so excited and THANK YOU so much for doing this!!

I have a plywood question for you--I have a couple sheets already that are NOT water resistant. Since I live in the PNW, that's not gonna work out:). Do you know what I could put on the sheets (the whole thing, actually!) that would allow me to use what I have?

Love the pic of all of you working on your house!!

If i want to make this bigger can I just change the measurements and will it still have enough support? I have been planning on making one more like 8X10. Thanks!

About the plywood... most isn't water resistant, untreated and laying flat. But once the ends are covered and it is standing upright, as long as it's not in contact with the ground, a good paint job and you should be good.

Don't use pressure treated unless it is in contact with the ground. P.t wood is continually giving off fumes and very hazardous to children, especially if ingested.

No road access? Do you have to take a boat to get to the road to drive to the orange/blue??!! You must be the most organized person - I can see myself forgetting something and then what! You are amazing!

Don't limit yourself to just plywood. You can get a cabin look by using boards or even use siding. I have some leftover siding from the house that I might just burn up on the playhouse.

My husband and I looked at the picture of the stairs to your adult playhouse and we agreed that it's just the sort of thing we need on our property (we're on a hill, too). So, would you be willing to share what went into your stairs?
