Winthrop Garage/ADU Plan

1-Bedroom Garage Apartment ADU with Full Kitchen, Walk-In Closet & In-Unit Laundry

650 SQ. FT. | 1 BED | 1 BATH | 2-STORY | 2-CAR GARAGE

The Winthrop Garage/ADU Plan is a clean, efficient 2-story garage apartment that delivers a complete, self-contained living experience above a 2-car garage. With a full kitchen, a dedicated living area, a private bedroom, a full bathroom, a walk-in closet, and an in-unit washer/dryer, this is a true apartment — not just a bonus room — in a compact, cost-effective footprint.

Whether you’re building a rental unit, a guest cottage, a multi-generational living solution, or a home office with a full suite, the Winthrop delivers everything you need in a straightforward, well-designed package.

Key Design Features

Full Kitchen: A complete kitchen — not a kitchenette — makes the Winthrop a fully self-sufficient living unit for long-term tenants or permanent residents.

Private Bedroom with Walk-In Closet: A dedicated bedroom with a generous walk-in closet provides comfortable, private living separate from the main home.

In-Unit Washer/Dryer: Laundry hookups within the unit keep daily living completely independent and convenient.

Full Bathroom: A complete full bathroom serves the bedroom suite and living area.

2-Car Garage: A full 2-car garage at ground level provides secure parking and additional storage.

Every blueprint in our collection is crafted with a strict focus on structural flow and spatial efficiency.
