Start small... go big!  With this simple outdoor sectional piece plan, you can make an outdoor sectional as big (or small) as you need, as your budget or schedule allows.  Build a couple sectional pieces this year, add on next year - the options are endless.

Easy to Build Corner Piece

It's easier than ever to turn corners!  We've updated the plans so all you have to do is add an arm piece to the basic sectional piece to create corners for your sectional.

Standard Outdoor Cushions

Each sectional piece (including the corner) fits a standard 25" x 25" deep seat cushion, up to 5" thick.  For corners, you may need two back pillows.  

If you purchase the cushions in sets with both backs and seats, consider purchasing another set, and using the spare seat cushion on an ottoman.

Another thought I had on the foam is look at foam mattress toppers that you could cut to size. Sometimes buying the whole thing and cutting yourself can save some money!

Thanks for the great plan! We are going to put in a paver patio by the pond and I was trying to think what would go well on there. BINGO! I see the corners are larger to accomodate for the side cushions and arm rest. Will those plans be made avauilible as well? Thanks so much.

ANA- you know how much I love you and your blog BUT this is a hate mail comment!!! COULD YOU NOT HAVE POSTED THIS PIECE prior to me buying a set for my screened porch ............... I BEGGED for a sectional for our screen porch but it wasn't in the budget. I have already made several of your pieces and know for a FACT I could build this for less than I paid for my furniture out there now..... Do you think if I craiglisted the furniture the hubby would notice.... OH well...I have my wishlist prepared for next year!!!! Thanks for all you do...You have inspired me to go beyond where I feel safe! As I say never underestimate a woman who thinks she can!

When your directions say to use the 2" or the 1 1/2" screws - how many am I using at a time? I know this may sound like a ridiculous question, but if I drill pocket holes - do I use one pocket hole or two and what is the spacing between the two? I am just curious about making it as sturdy as possible. Thanks!

Thanks all for your comments! Make sure you read the last two steps, I talk about how to connect sectional pieces and also a simple modification if you are worried about your back cushions falling through (trust me, that was a concern of mine too!)

As far as screws go, I don't give specific information because I trust that you are smart and that you can use your best judgment. You always need at least two screws, and often that's plenty. Your pocket hole jig (at least the Kreg Jig) has two holes on the jig correctly spaced for drilling two at the same time.

Gotta say, I'm dying to build this myself! Ugh!

I am going to build this for our family room husband is having severe back pain and needs a taller higher? seat (from the floor to the cushion) I don't think it would be hard to add a couple of inches to the height would it? I'm gonna paint mine black and cover the cushions in drop cloth fabric :)) It will be next month, but I'm going to get this done. Thanks so much!!!

I thought I'd post this on both parts of the sectional posts:

I modeled this up with an addition - a couple of end tables that could serve as extra seating, tables, or if you built them to size, they could fit into the empty part of a "U" shaped configuration to make a giant outdoor "daybed/lounger" - at least that is how I'm planning on configuring my sectional!!! You can check out my idea (there are two pictures) on the suggestion board of the KOW flickr group:

Ana, I must say, YOU ROCK!!:) I posted something like this on your facebook page for plans request and never thought you would get around to it after seeing all the other plans people had posted. You must feel overwhelmed!! I just wanted to say thank you. I know you hear it all the time but you are so inspiring! I have been thinking about the outdoor cushion thing and someone had mentioned to buy only the outdoor foam to prevent mold and help to dry quicker after rain. I think you could also buy regular foam and then purchase an inexpensive vinyl table cloth and make a cover out of that for cushion first then proceed to make the regular fabric cover. Also, you could sew 3 sides and sew velcro on the end and close up like that. Kinda like wrapping a present... Then they would be easy to remove to throw in wash when they needed it. Just a couple ideas:))
Thanks again for all you do:) I HAVE to check you blog daily. I'm addicted!
