Where the architecture degree and the multifamily brokerage overlap. Small apartment buildings are expensive because every one is a custom design. Structural insulated panels, prefab kitchen and bath pods, shared utility risers, and standard stair modules make the structure repeatable; a separate facade layer keeps the buildings from looking like it.

Panelized is a browser-based massing and unit-planning tool for that system: pick a story count and unit mix, place pods and risers, and see the building in 3D with a cost model that rewards repetition. It exists to test a thesis about the missing-middle housing that Chicago’s two-flats and three-flats used to provide, using the constraints I see on the brokerage side of the same buildings.
