Overall cost: $$$. Lumber varies by region, species, and season, so we give a band rather than a figure.
Tools: Circular Saw. Materials: 3/4" PureBond plywood, full sheet
Have your lumber yard rip the full plywood sheet into a 24"-wide strip and a 13-1/2"-wide strip, then make all remaining crosscuts yourself according to the diagram.
Tools: Drill / Driver, Drill Bit Set, Pocket Hole Jig. Materials: 2x2, 8 ft, Self-tapping star bit screws, 3" (or pocket hole screws, 2-1/2"), Pocket hole screws, 1-1/4", Wood glue
Build the two end frames from the vertical posts and angled roofline pieces, using a countersink bit and 3" screws, or a pocket-hole jig with 1-1/2" pocket holes and 2-1/2" pocket hole screws. For the angled joints, clamp, glue, and predrill with a countersink bit, using just one screw per joint to avoid splitting the wood. Build two and confirm they match.
Tools: Drill / Driver, Tape Measure. Materials: 2x2, 8 ft, Self-tapping star bit screws, 3" (or pocket hole screws, 2-1/2")
Join the two end frames with the horizontal ties. Confirm the top tie sits exactly 13-1/2" above the top story's tie — this measurement keeps all three stories consistent.
Tools: Drill / Driver, Pocket Hole Jig. Materials: 3/4" PureBond plywood, full sheet, Pocket hole screws, 1-1/4"
Secure the plywood floors to the frame with 3/4"-stock pocket holes and 1-1/4" pocket hole screws on all sides, or with scrap 1x2 corner braces and countersunk screws if you don't have a jig.
Tools: Brad Nailer, Jigsaw, Pocket Hole Jig. Materials: 3/4" PureBond plywood, full sheet, Brad nails, assorted, Wood glue
Cut the stair openings in the floors per the diagram. Add the bottom-story walls (offset slightly between stories if nailing, to give yourself something solid to nail into), then the middle-story interior wall, then the top-story walls and interior wall system.
Tools: Brad Nailer. Materials: 1/4" plywood scraps, 1x2, 8 ft, Brad nails, assorted, Wood glue
Build the stairs by stacking the 1x2 treads staggered, gluing generously and nailing carefully. Attach the scalloped 1/4" plywood roof strips, lapped and nailed down.
Tools: Random Orbit Sander. Materials: Caster wheels, 2", with screws for 3/4" stock
Attach the caster wheels to the plywood base so they swivel freely. Sand and finish, or decorate interior walls with decoupaged paper as desired.
