How to Build a Classic Playhouse

Thrill the kids or grandkids with this two-weekend project.

As the handyman in my family, I must confess that there are a lot of jobs I’m not crazy about: the drain that always needs unclogging, the squeaky floor that I’ve struggled with for months, the perennial battle of the bulging gutters. You’ve probably got a similar list of your own. Satisfying though these jobs can be when you finish, no one, not even the most hard core among us, would call them fun.

But heres one thats different, a project thats pure delightthe icing on the handymans cake. The work is easy, and absolutely nothing beats the feeling youll get from watching kids having a blast in the playhouse youve made.

I designed this playhouse so it can be built as quickly as possible. Two beginners could put it together in a couple of weekends, including the painting, and an experienced do-it-yourselfer could build it alone in about the same time. Its a no-worry type of project, too, with few chances to screw up, and without much need for precisiona perfect project to get the kids to help on!

Skills and Cost for this How to Build a Playhouse Project

No experience required could be the motto for this playhouse. You need to be able to use a circular saw and a jig-saw to build it, but the cuts are simple enough (and the project forgiving enough) that even if youve never picked up these tools before, you could learn while you work. Be- sides a jigsaw and a circular saw, youll need a cordless drill with a Phillips-head bit for driving screws, a chalk line, level, rafter square (the big one thats about 2 feet long) and a stepladder. A power sander is helpful but not essential. The materials for our playhouse cost $350. You may be able to knock about $50 off by using plywood with the grooves farther apart, but it wont look quite as much likea real house.

How to Build a Playhouse: Cut a Bunch of Parts at Once

Get out your circular saw, don your safety glasses and dive right in by cutting the parts of the playhouse to size. When you cut the treated lumber, wear a mask so you dont breathe in the dust. You can cut parts A through L now, but wait until later to cut the remaining pieces.

To save time and prevent mistakes, cut the lumber to length on top of sawhorses, where you can cut several pieces at once (called gang cutting by carpenters). This is especially useful when cutting the floorboards (E). Mark the angled ends of part C with a protractor (a 79 school model is fine), or use an angle-cutting guide for your circular saw.

The plywood is easier to cut on the ground (Photo 1), using a piece or two of lumber to raise it up. Use a chalk line to mark the cutting lines. Cut straight, but dont worry if the edge isnt perfect; every cut edge will be hidden in the finished playhouse. Youll notice that the edges of the plywood arent square; they have a little lip on them so one sheet fits into the adjacent one. For this project, dont worry about this joint. Just cut the plywood as shown in Fig. A and everything will fit.

How to Build a Playhouse: CUT OUT THE PARTS

 

1. First. Its easier to cut the plywood on the ground like this, supported by a 2×4or two, than to cut it on sawhorses.

How to Build a Playhouse: NAIL TOGETHER

2. Each wall while its on the ground. If the plywood is cut square (check it!), the wall will automatically be square, too.

How to Build a Playhouse: SCREW ON THE RAFTERS

3. From the inside, using galvanized deck screws. For longevity, weve used treated lumber throughout.

Assemble the Front and Back

Now the fun beginsnailing parts together! The first step is to assemble the front and back walls, one at a time. Lay out (on the ground) the three 2x4s (parts A and B) that support the end wall. Place the plywood parts G and H on top of the 2x4s, and make sure that the edges of the plywood fit together. Then nail the plywood to the 2x4s, measuring in from the edge to find the location of the middle stud, part B, which is not centered (Photo 2). If you have trouble hitting this piece with the nails, heres a tip: Snap a chalk line across the face of the plywood to mark where the middle of the 2×4 is, then nail on the line. When youre done nailing, screw on the rafters (part C) from the inside of the wall (Photo 3).

After youve completed one end wall, carefully lay out the other one to avoid a very easy, and absolutely maddening mistakemaking both walls exactly the same. They need to be mirror images, a front and a back, rather than identical. So measure for part B from the left on one wall and the right on the other; otherwise the house wont go together correctly. I cant even count the number of times Ive made this aggravating blunder.

How to Build a Playhouse: CONNECT THE WALLS

4. With the plywood sides and the floor joists. Leave off the last side piece so you can get inside to work.

Attach the Sides to Make a Three-Sided Box

Whistle for your helper because now its time to raise up the front and back walls and connect them (Photo 4). Prop up one wall on your level site and screw the floor joists (D) to it, making sure theyre square to the wall. Then screw the other wall to the joists. Screw part F to its respective joist, then nail on the plywood for one side (parts J and K). Nail on part K on the other side, but not the larger piece of plywood (J). This allows you to get in- side the house to work. (Remember, theres no door yet!)

This is a good time to put blocks or shims under the corners of the house to get it plumb and level (Photo 5), because its going to get much heavier from now on.

How to Build a Playhouse: LEVEL

5. The playhouse now, before it gets any heavier. Use scrap pieces of treated lumber to lift the corners where needed.

Prepare Your Site

A playhouse doesnt have to last forever, so forget about concrete blocks, mortar and a complicated foundation you can build this playhouse directly on the ground.

You need a fairly level spot, about 6×6 feet. Use one of your boards (like part D) and a level to check the slope, and dig and pack the soil to level it out. Your spot doesnt have to be perfect; its easy to slip a few scraps of treated wood or a patio paver under a corner of the finished house to get it level (Photo 5).

How to Build a Playhouse: NAIL THE FLOORBOARDS

6. To the joists. Youll need small support blocks at the ends, where the floorboards are cut short to fit.

A Solid Floor That Can Take Abuse

The floor on this house is built sturdily, like a miniature deck. The first step in building it is to attach the two small support blocks (N). If you have trouble with them splitting, use a smaller nail or drill pilot holes and screw them on.

Lay the full-length floorboards on top of the joists, then measure and cut the shorter ones that fit around the up- right 2x4s of the walls. When all the floor boards fit well, nail them on (Photo 6).

How to Build a Playhouse: NAIL THE ROOF

7. Supports in place from the ends. For a good fit, its best to hold these boards where theyre going to go, mark them and then cut.

A Roof Like an Upside-Down Boat

Now for the roof, and a weird roof for a house it is no shingles, no tar paper and no rafters. Its actually built more like an upside-down boat, with ribs (part M) and a hull of thin plywood strips (L). But it works, its fast and its perfect for a playhouse.

Begin by nailing on the ribs (M). Hold the board in position, mark the board for length, cut it and nail it in place (Photo 7). This is easiest to do with a helper, but if your helpers off playing, hold the other end of the board with a nail.

Now attach the lowest strip of plywood, lining it up so it overhangs part C by 1 inch, and nailing only at the ends. When you lay the next sheet on top of it, line up the upper edge of that sheet with a rib (M), and then nail through both pieces of plywood where they overlap. Be sure the nails go into a rib. Snapping a chalk line across the plywood will help you know where to nail.

The ends of the plywood pieces may not line up perfectly, but thats something you can fix. Just snap a chalk line and trim the pieces with your jigsaw. While youve got the ladder out, run some acrylic caulk into the joint where the plywood pieces meet at the very top of the roof (the peak) to help keep out the rain.

How to Build a Playhouse: THE ROOF

8. Is made of overlapping pieces of plywood that serve as large shingles. If the ends are uneven, they can be trimmed with a jigsaw.

How to Build a Playhouse: CUT THE DOOR

9. And window openings with a jigsaw. The corners are marked by driving a nail through from the inside.

Doors and Windows Are Holes in the Walls

Take a step back now, get a cup of coffee and admire your work for a few minutes. You dont want to rush into this next stepcutting the openings for doors and windows.

Start with the door. From inside the playhouse, drive a nail through the plywood at the corners of the door open- ing, flush with the floor and the 2×4 uprights. From the outside, wrap your chalk line around the protruding nails to mark where the door opening is to be cut. Pull the nails, drill a 1/4-inch hole at each nail hole and saw out the door opening with your jigsaw, using a fine-tooth blade (Photo 9). Clean up the edges with a rasp or sander.

Once the door is cut, nail on the last piece of plywood (J). Cutting the windows is easy; simply mark the openings with pencil on the outside and cut them out. We made three windows, one in front and one on each side, but you can add more or make them larger.

How to Build a Playhouse: NAIL ON TRIM

10. Around the door and window openings after it hasbeen cut to fit. We tacked on the trim temporarily, then removed it for painting.

Add Some Snappy Gingerbread Trim

Carpentry is like lifesometimes you need to follow a strict plan and sometimes you need to go with the flow. Adding trim to your playhouse is a time for the latter. Rather than strictly following a cutting list, youll get better results if you hold each piece of trim in place, mark it and cut it to fit. If you miss the mark and cut a piece too short, either use it somewhere else (I cut the longest pieces first whenever possible), or fill the gap later with caulk.

Dont worry if there isnt a 2×4 to nail into in some places; screw the trim on from the inside wherever necessary. Tack all the trim pieces in place with just a couple of nails, and dont drive the nails in all the way because youll want to remove all the trim for painting. It sounds crazy, I know, but its a lot easier than painting the trim once its on the playhouse.

Start with the vertical 1×4 corner boards (P) on the sides of the house. Then move on to the front corner boards, the horizontal boards and the vertical piece around the door (Photo 10). Build the little caps for the tops of the window openings, nailing part U onto part T. Then cut the other window trim. With a jigsaw and drill, cut the decorative roof trim (V), give it a test fit and sand it smooth.

Painting Is the Final Touch

Youre probably dying to start painting at this point, but try to hold your horses for a minute. You should first round off, using a rasp and sandpaper, any sharp edges and corners that kids might hurt themselves on. Pay particular attention to the roof corners and the edges around the windows and doors. Treated wood is often somewhat damp, so give it a few days of good dry weather before you paint.

Now you can paint (hooray!). Remove and label all the trim before painting. Paint the roof before the sides, so you wont drip (or bump into) the wet paint. A roller with an extension handle will make those flat surfaces go quickly.

For a more cheerful playhouse, its worth painting the inside walls and ceiling white. For all the painting, use an exterior primer, then two coats of paint. We used a latex floor paint for the roof because it had a good deep color.

Nail and screw the trim back on, touch up the paint, and your playhouse is ready for the kids to move in.

Gussying It Up

There are lots of improvements you can make to our basic design. Here are some ideas:

Make the paint on your playhouse last longer by putting a partially buried concrete block under each corner, enough to raise the playhouse a couple of inches off the ground. Just dont raise the front more than a few inches, or the step will be too high.

Put on a shingle roof. If you want to do this, use 5/8- inch or 3/4-inch plywood for the roof, so the tips of your roofing nails dont stick through on the underside, a real hazard for the kids.

Add curtains, or even mosquito screens, to the windows. If attached with Velcro or screwed-on strips of wood, the screens are easy to remove and repair.

Embellish with fancier trim. Use a jigsaw to cut your own gingerbread design, or buy some commercially made trim.

Add a light. You probably dont want to mess with buried electrical wiring, but battery-powered closet lights or camping lanterns work fine.

And most important, have fun!
