Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!

WINDOWS - CUT TO FIT
First, cut out all the pieces. If you don't have a truck or tablesaw, it might be easier to have your home improvement store rip your plywood into 22-3/4" widths, 8 feet long. Then cut the longest pieces first.
The top roof angle is 45 degrees. You can easily find this by finding the center of your side and middle panels (at the top). This distance should be 11-7/8" from the sides. Then measure down 11-7/8", and draw a diagonal between the two points.
Then mark out all windows and doors and cut out with a jigsaw.
Once the pieces are cut, attach the floor to the walls. I used a Kreg Jig set at 3/4" and 1-1/4" pocket hole screws.
Next, add the floors. I used 3/4" pocket holes on the underside and 1-1/4" pocket hole screws.
Because we opted for one large room on the top floor, I opted to use plywood for my roof (no center support without the divided upper room). Keep top edge flush as you attach room with glue and finish nails or staples.
I built my front roof first with 3/4" pocket holes and 1-1/4" pocket hole screws, and then attached to front of dollhouse with finish nails and glue.
For the back, I used 1/4" plywood and nailed it to all of the walls and floors with glue.
We opted for caster wheels instead, but you could also finish out the base with 1x boards. Shown in the diagram is 1x4s.
I measured each window and built the window trim to fit snugly, gluing in place when I was done.
I haven't added shutters yet, but this is what 1x2 shutters would look like.
