I will document the build of a modern house in 1:12 scale. Let me know your thoughts and questions!
The build is similar in style to another modern house I made a couple years ago, which featured bold right angles, solid lines, lots of glass, and a sweeping roof opening up the overlapping second floor to the maximum amount of light and views. The main differences with this project, which I've dubbed Lumière, is that it's wider, the window configuration is different, and it's taller to accommodate a third-level catwalk for additional storage. The client's wish is to use this as a display for her vast collection.
The first task was to float some ideas based on the general principle. While I started down the path of a skylight (her request) and even partial glass floors, we eventually scrapped that idea in favor of solid surfaces and no skylight. The other change to this proposal was that the catwalk goes around two sides of the interior, instead of three.
Next thing is to build the main structure. I used a bass of solid thick MDF, and walls of thinner MDF. This construction will have both an exterior and interior wall, with wiring within the walls.
Getting the dimensions right for the walls:
Here the second level floor is cut and going into place:
