Intent

Compress a dwelling into a small spherical shell without losing orientation, daylight, or usable interior volume.

System

The shell works around a central column that can carry stair, storage, wet wall, and utilities. radial ribs distribute roof loads and leave the perimeter open for windows, furniture, and circulation.

Use

The project is a housing prototype for small sites, backyard units, retreat cabins, and spherical construction studies.
