Modular Construction TA
The interior construction will be based on panels.
Wall panels will be a standard size. They will be affixed to the frame so they can be removed. I can start by simply using drywall. Then, over time, I can replace them with simple wood panels. The ultimate goal is to have CNC cut wood carvings.
The floor is also a sort of panel design. The main structure of the floor will form a grid and the floor boards will fill in the cells. But any one section can be removed.
