Winthrop 35 Enclosed Garage/ADU Plan

1-Bedroom Enclosed Garage Apartment ADU with Interior Staircase & Full Kitchen

887 SQ. FT. | 1 BED | 1 BATH | 2-STORY | 2-CAR DRIVE-UNDER GARAGE

The Winthrop 35 Enclosed is the interior-access version of the Winthrop 35 — delivering the same complete, self-contained apartment experience with the added privacy and security of an interior staircase. With a full kitchen, dedicated living area, private bedroom, full bathroom, walk-in closet, and in-unit washer/dryer, this is a true apartment above a 2-car garage in a clean, efficient footprint.

Ideal for rental income, multi-generational living, or a private guest suite, the enclosed staircase design keeps the apartment fully integrated and weather-protected year-round.

Key Design Features

Interior Staircase Access: A private interior staircase provides secure, weather-protected access to the apartment — ideal for year-round rental or multi-generational use.

Full Kitchen: A complete kitchen makes the Winthrop 35 Enclosed 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.

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

2-Car Drive-Under Garage: A spacious 980 sq. ft. drive-under garage provides secure parking and substantial storage below.
