PLAYHOUSES

Kids' playhouses in one 3D configurator. Pick a number, drag the footprint to size it and switch the options on the bar below. Each one is a buildable design: every board, sheet, screw and hinge in the model is a real catalog item, so the priced bill of materials, the cut list and the assembly steps follow every change.

• 1 Cottage -- A little timber cottage under a steep gable roof of asphalt shingles: panel siding with corner boards, a board door on strap hinges and three windows with shutters. It stands on precast deck blocks; the front porch with its decking switches on and off. No glass and no lock -- the door has a knob and a ball catch, so a child can always get out.
• 2 Stilt House -- The cottage raised 1.2 m (4 ft) on 4x4 posts in ground screws, braced underneath. Its porch turns into a lookout with a guard all round, a ladder up the front and a wave slide off the side that you switch on or off; under the floor, a shady den to play in.
• 3 A-frame Hut -- A steep A-frame whose shingled roof comes right down to the floor on both sides, like a timber tent. A board door in the front gable, a window in the back one and collar ties up in the roof; it stands on precast deck blocks, and the little front porch switches on and off.
• 4 Play Fort -- An open lookout tower on four posts in ground screws: a deck 1.2 m (4 ft) up behind fort walls of pointed boards, a ladder up the front, a wave slide off the side and a shingled roof overhead. On the toggle, a swing beam runs out of the back gable to an A-frame with two board swings.
• 5 Modern House -- The cottage's frame under a low mono-pitch roof of standing-seam metal that falls from the tall wall to the low one, with deep eaves on rafters that run past both gables. A wide window in the tall wall, a square one at the back, charcoal siding and a wooden board door; the covered front porch switches on and off. No glass and no lock, as on every house here.
• 6 Little Barn -- A tall gambrel roof on trusses of four straight pieces joined with OSB gussets, covered with asphalt shingles; red siding with white trims and corner boards. Double board doors in the front gable with a hayloft door above them, and windows with shutters in both sides and the back. Inside, the loft over the doors switches on and off, with its guard rails and a ladder. No glass and no lock, as on every house here.
• 7 Tree Fort -- An open deck 1.2 m (4 ft) up, built round a tree in your garden on four independent posts in ground screws: nothing is fixed to the tree, so it can grow and sway. The trunk passes through a framed opening and the deck boards are cut round it with a 5 cm (2 in.) gap; set the trunk's diameter on the slider. Fort walls of pointed boards, knee braces under the deck, a ladder up the front and a wave slide off the side that you switch on or off.
• 8 Castle -- Crenellated board towers on one deck 1.2 m (4 ft) up, joined by bridges that serve as the wall walk over open gates. On the bar below you switch the plan between two towers, three in a row or an L, and the towers between pyramid roofs of asphalt shingles, tall roofless towers with windows and a door to each bridge, a mix of both, or low ones. A ladder up the front and a climbing wall with bolt-on holds; the monkey bars and the wave slide switch on together, one at a time or not at all. Drag the footprint to size the towers and the bridges.
• 9 Climbing Cube -- An open timber cube to climb on and in: 4x4 posts in ground screws, top beams and bottom rails joined by black steel corner brackets, and a rope cargo net stretched over the top. Tap the disc in front of each side to choose what fills it -- a climbing wall with bolt-on holds, a rung ladder, a rope ladder, a cargo net, a panel with hand holes, or nothing; open sides get knee braces. Inside hang gymnastic rings and a knotted climbing rope; on the toggle, a nest swing hangs from the middle beam carried out the back to its own A-frame -- never inside the cube. Drag the footprint from 1.8 to 3 m (6 to 10 ft). Plan soft surfacing underneath: the top net is 2.4 m (8 ft) up.
• Every model stands on the foundation you pick on the bar below: ground screws, precast deck blocks or poured concrete footings. The brackets, the concrete and every nail are in the bill.
• Step-by-step assembly for every model: each group of parts goes in, then the screws that fix it, with a cut list and a PDF to take outside.
• Stand the finished piece in your yard at full size in augmented reality, straight from your phone.
• Instant, itemized bill of materials with real supplier part numbers, in metric or imperial -- down to the last screw.
