Standing and Fixing the Walls
Step 8. Fixing the walls in place
Clamp a couple of blocks to both end joists to prevent the front and rear walls from slipping off the joists while they are being worked on.
Stand up the rear frame and hold it in place with a temporary brace.
Do the same with the front wall.
Mark a couple of pencil lines across each of the two side walls 11 1/4″ (280mm) in from the front end and 8″ (200mm) in from the rear end (see drawing below). 
Also refer to the side elevation plan (Page 3).
Clamp the side walls in place ensuring that the insides of the front and rear walls line up with the pencil lines on the side wall (as mentioned above).Bolt the side walls to the 1 1/2″ x 1 1/2″ (45mm x 45mm) battens on the front and rear walls using 3/8″ (10mm) galvanized bolts. Pre-drill the bolt holes first.
Allow for four bolts at each corner.Shave or shape (with a planer or sander) the top of the side walls to be flush with the rake of the top of the front and rear walls (see drawing below).
Hello there,
First of all thanks for posting the plans for this project on the web for all to use. The friends kids love it when they come round for the garden parties etc.
It is quite a lot of work and took me a whole week to complete, after all the parts were delivered. I was working approx 8 hours a day for 7 days. It is a good idea to make sure all the tools you require are sharp and in good condition so that you don’t have to stop in the middle of a cut etc.
The one point I would like to highlight is that the 90mm cut in the end panels for the lower roof sections doesn’t take into account the 18mm of board that forms the lower roof section.
To clarify. If you measure up 130mm along the vertical edge of the end panel and join this to a point 930mm to the right of the vertical edge, it will be the correct distance from the parallel line drawn from the lower left corner. Those calculations will work out correct. The parallel lines will end up at approx 108mm apart.
What is incorrect is the number shown on the drawing stating that the parallel lines will be 90mm apart. When constructing the playhouse you will be using a 90mm piece of lumber screwed to a 18mm piece of plywood which means the parallel lines should be approx 108mm apart.
I have got some pictures attached here and will be completing a blog about it at http://www.bunglesmate.co.uk/blog/2014/10/04/saturday-27th-september-2014-playhouse/
Hi, I built the plywood playhouse from these plans: https://www.buildeazy.com/plywood-playhouse/ Just finished a couple days ago.
I don’t recommend this project for someone with no prior carpentry experience as there are a number of cuts that require angled mitre cuts and some of the plywood cuts are really long. The instructions were fairly easy to follow with only a couple of dimensional hiccups. Foremost, the side walls, using standard 4×8 plywood, do not quite reach the lower roof. I didn’t have to trim that edge to fit the slope, which was kind of a relief. However, there is about a 1″ gap. Everything else worked pretty well and I love the design. Here are some other changes and comments:
– I used 5/8 plywood on the roof/ceiling to save some money and because 3/4 everywhere seemed a bit overkill. You could run a truck into this thing and the truck would break first.
– I didn’t have a workshop space with a tall enough ceiling to finish initial construction inside, so I had to finish installing the roof on-site. This was no problem except for the painting. I definitely recommend painting this thing in panels (per the plans) instead of assembled like I did.
– I skipped the plexi windows because they seemed like the one afterthought in the design, plus I thought it would be better to maintain air flow and keep it cooler inside. We’ll see how that works out in the winter. I may change my mind.
– I used one of the scrap pieces of plywood to make a little desk in the back corner.
– I used a router to round most of the plywood edges. They seem less splinter prone this way and seemed to take paint better.
Here are a few pictures.
Thanks for the plans and your website. My 3-year-old son loves it and it’s big enough to keep him happy for years!
