1-Bedroom Craftsman Garage Apartment ADU with Private Exterior Stair & Covered Deck
780 SQ. FT. | 1 BED | 1 BATH | 2-STORY | 2-CAR GARAGE
The Winthrop 30 pairs a 780 sq. ft., one-bedroom living unit with a full two-car garage below, reached by its own private exterior stair and covered landing. Inside, an open kitchen, living and dining area shares one bright volume, with a bedroom, full bathroom and generous walk-in closet tucked down a short hall.
The plan ships with two alternate layouts for the bath/closet zone, so you can choose the configuration that best fits how you'll use the space — while fiber cement lap siding, a covered deck and a classic gable roof with 16" x 16" wooden brackets give the exterior real Craftsman character.
Full Two-Car Garage: A ground-level, two-bay garage with a pair of 9' x 8' garage doors handles vehicles, storage or a workshop independent of the living space above.
Private Upper-Level Living: A private exterior stair and covered landing lead to a self-contained one-bedroom, one-bath unit — ideal for a rental, guest suite or multigenerational living.
Two Bath/Closet Layout Options: The plan includes two alternate configurations for the bath and walk-in closet zone, so you can pick the fixture and storage arrangement that suits you best.
Open Kitchen & Living: The kitchen, living and dining areas share one open volume with an island and an uncovered porch just off the kitchen for extra outdoor space.
Craftsman Exterior Details: 16" x 16" wooden brackets, composite shutters, fiber cement siding and an eave return that matches the main house give the garage/ADU real architectural presence.

What foundation does Winthrop 30 come with?
Winthrop 30 is drawn on a slab on grade foundation. A local engineer sizes the foundation for your soil and wind zone.
How tall is Winthrop 30 and how much ground does it cover?
The maximum ridge height is 26' 8". The footprint is 31' 8" x 30' 0", which is the number to check against your setbacks; porches and the garage count toward it even though they are not in the heated area. Heated living area is 780 square feet on 2 stories.
