A backyard playhouse gives kids a place to imagine, play and stay active outdoors – and it is a genuinely fun woodworking project to build. With a clear plan and a free weekend, you can build a safe, sturdy playhouse that lasts for years. Here is how to do it right, with safety built in from the start.
Plan the playhouse around safety and age
Before you build, think about who will use it and for how long:
- Toddlers: keep it low to the ground, with wide openings and no tall drops.
- Older kids: a raised floor, porch, ladder or slide adds years of play value.
- Footprint: a 6×6 to 8×8 base suits most backyards and gives room for a small porch.
Choose a level, well-drained spot with some shade, and leave a soft fall zone (grass, mulch or rubber matting) around any raised areas or slides.
Tools and materials
Tools: circular saw, drill/driver, tape measure, square, level, sander and a socket set for lag bolts. Materials: pressure-treated lumber for the base and posts, framing lumber for walls, exterior plywood or cladding, roofing, exterior screws and lag bolts, and a child-safe exterior paint or stain.
Step-by-step playhouse construction
1. Build a level base
Start with a square, pressure-treated floor frame. For a raised playhouse, set sturdy posts and bolt the frame to them, keeping everything plumb and level. Deck the floor with exterior plywood.
2. Frame the walls
Build each wall flat, framing generous window and door openings so kids can see out and climb in easily. Stand the walls, fasten the corners, and check for square.
3. Add the roof
A simple gable roof looks like a real little house and sheds rain well. A covered porch roof is a popular upgrade that adds shade and character. Sheath and cover the roof with lightweight roofing.
4. Build the porch, railings and access
If your design is raised, add a porch with railings, plus a ladder, steps or a slide. Space railings no more than 3.5 inches apart so small heads and limbs cannot get stuck, and keep any climbing surfaces gently angled.
5. Sand, round and finish
This step matters most for kids. Sand every edge smooth, round sharp corners, and countersink or cap all screws and bolts so nothing can scratch. Finish with a non-toxic exterior paint or stain rated safe for children.
Safety checklist before the kids move in
- No exposed screw tips, nail points or splinters anywhere they can reach.
- Railings on all raised edges, with safe spacing.
- Windows and doors sized so kids cannot get trapped.
- A soft landing surface under slides and elevated areas.
- Every joint pulled tight and rechecked after the first week of use.
