How to Build a DIY Playhouse Railing
- Miter saw
- I used my miter saw to cut all the 2x4s, but you could also use a circular saw for this.
- Impact Driver
- Kreg Jig
- Nail gun
- Speed square
- Measuring tape
- Optional: FinishMax paint sprayer
- Wood (I used regular lumber, if you paint/seal it for the outdoors it will last for years)
- (4) 2×4 8′ boards
- Left over 4×4 pieces from the wall build
- (24) 2 1/2″ blue-kote pocket hole screws
- (4) 4″ TimberLOK wood screws
- 2″ 16 gauge nails
- Exterior paint
- I used Ultra White by Behr left over from the walls.
The front opening of the DIY playhouse should be 73″ wide (same as the back wall dimension). Double check the measurement and adjust if necessary. I built & installed the playhouse railing by myself and it took me about 6 hours total. It would have been much easier to install with a second pair of hands, but was doable without (with a few moments of frustration and maybe a bad word or two).
Cut 2 pieces of 4×4 to 30″ long. I trimmed the top of the posts by cutting 1 1/2″ off the top at a 45 degree angle on all sides.
Cut 6 pieces of 2×4 to 22″ long. Set the Kreg jig for 1 1/2″ lumber. Drill 2 pocket holes in each end of the 22″ boards.
I chose to sand and paint all the pieces at this point. I figured it would be better than trying to paint around the deck once installed. I used my FinishMax paint sprayer to make painting the playhouse railing in the summer heat fast and easy.
Once dry it was time to assemble. This was the part that I wish I had a second pair of hands for. I chose to secure the 2×4 pieces to the post, then the post to the deck, then the 2×4 pieces to the wall. I don’t know if this was the easiest way or not, but it worked.
Attache the 2×4 pieces to the posts and wall so the bottom 2×4 is 3″ off the ground and the top 2×4 is 26 1/2″ off the ground.
Attach the 4×4 posts to the deck so they are level with the front of the wall. Secure them with 2 4″ screws through the bottom of the deck into each post.
Once the frame is secure, it is time to add the X in the middle. I measured the inside dimension from corner to corner. It was 31″. Cut 3 2×4 31″ long and cut at a peak at each end by taking 3/4″ off each side at a 45 degree angle.
Secure the first angled board in each railing opening with finishing nails. I used 2 nails in each corner in each side.
Mark the center of the first angled board. Measure from the corner to the center. Mine were about 14 3/4″ long. Cut one end of the boards with the same peak as the longer angled boards. Secure these into place with the finishing nails too.
Now the rest of the railing is ready for paint. I chose to not paint these angled boards before installing because they required a bit more tweaking to get the pieces to fit properly. And since the X pieces are not touching the deck, it is easier to paint them installed, I just need to do it now that we are back from our camping trip.
And now for the $$$. Here is what we have spent so far:
- The deck = $196.96
- The walls = $189.71
- Slide = $99.99
- Rock climbing handles = $20.00
For the railings:
- (4) 2×4 8′ boards = $12.64
- 4×4 boards (left over from the wall build)
- (24) 2 1/2″ pocket hole screws (had on hand but a box of 50 is around $5)
- (4) 4″ TimberLOK wood screws = $5.12
- 2″ 16 gauge nails (had on hand but a box of 1000 nails is around $12)
- Exterior paint (left over from the wall build
Total for Railing: $17.76
Total so far: $524.42

So now I have to finish washing all our smokey clothes & bedding, then it’s back to work to get this project finished!
