About This Model

The B-705 appeals to two specific client profiles: homeowners building for a parent or adult child who will be in the space for years and want them to be genuinely comfortable, and rental clients in high-value Madison neighborhoods where the rent market supports the premium. In neighborhoods like Vilas, Monroe Street, or the Near West Side, a well-finished B-705 can command the top of the Madison 1-bedroom rental market. At 705 square feet it also approaches the range where some municipalities’ ADU size caps become a consideration — confirm your municipality’s limits during the feasibility check.

Ideal For

Long-term owner use, high-end rental where the market supports a premium, aging parent who wants space to host family visits.
