Started on the second floor today. Glued in all the beams and joists first, with little holes through which the wires pass.
Then I cut out the floor as one big piece.
Measured and drew where the walls would be.
And cut part of those wall areas out so I could pass the wall studs through them later on and help strengthen the framework.
Next I cut out the walls for the bathroom, including an opening for the doorway. There will also be a window somewhere on the left, but I haven’t decided where yet.
Added a ceiling on top and you can almost imagine the bathroom done and ready to go….almost…
Good night.

Hi Juliette, As usual, I am Fascinated by the method of this build. Having actual studs and joists is wonderful to see and makes this house really appear REAL, as well as that it is two rooms deep which pulls the viewer in. The character of the home is already apparent and the more you do the more I like it!!! 😀 I am curious though, about the weight of the matt board that you are using for the interior walls, because it looks really sturdy.

Thank you! Yes, it is indeed quite sturdy. It is 1/8 of an inch thick and can stand up alone (though it’ll bend some if I don’t add the studs). Can’t find it in a typical craft store…I have to go to places that sell framing matts to buy it.
