About This Model

The A-360 was designed specifically for the lots where other ADU models don’t fit. A 5-foot rear setback and 3-foot side setbacks leave very little buildable area on many Madison urban lots — the A-360 works within that constraint without requiring a variance or special approval. The compact footprint also means lower material costs, faster construction, and a lower permit fee calculation tied to square footage. For a rental ADU, the A-360 appeals to the same tenant pool as a studio apartment — single occupants, young professionals, students — at a competitive rent point with the advantage of a private entrance and private outdoor space that no apartment provides. It is a single-level 360 sq ft studio, with appliance packages available rather than assumed in the base price.

Ideal For

Tight urban lots, rental income on a constrained site, low-maintenance studio for a single occupant or couple.
