Winthrop Garage/ADU Plan
1-Bedroom Garage Apartment ADU Plan
650 SQ. FT. | 1 BED | 1 BATH | 2-STORY | 2-CAR GARAGE
The Winthrop is the plain, well-made version of the garage apartment: 650 square feet over a two-car garage, with a full kitchen, a living area, a bedroom, a full bath, a walk-in closet and a washer and dryer in the unit.
It works as a rental, a guest cottage, a place for a parent or a home office with a full suite attached. There is nothing unusual about it, which is the point: a complete apartment in a compact footprint that is inexpensive to build.
A full kitchen: a complete kitchen, so whoever lives here can cook every meal at home.
A bedroom with a walk-in closet: a separate bedroom with generous closet space, away from the main house.
Laundry in the unit: washer and dryer hookups inside the apartment, so laundry day never crosses the yard.
A full bath: a complete bathroom serving the bedroom and the living area.
A two-car garage: a ground-level garage for two cars and the overflow from the house.

The Winthrop proves a garage can be more than a garage: a complete apartment above it adds a place to live, rental income and flexibility to the property.

What foundation does Winthrop come with?
Winthrop is drawn on a slab on grade foundation. A local engineer sizes the foundation for your soil and wind zone.
How tall is Winthrop and how much ground does it cover?
The maximum ridge height is 25' 0". The footprint is 32' 0" x 25' 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 650 square feet on 2 stories.
What comes in the plan set for Winthrop, and what do I still need locally?
A licensed construction set: cover sheet with general notes, foundation plan, dimensioned floor plans for every level, all four exterior elevations, a cross section, roof plan, electrical plans, and door and window schedules, sold as PDF, PDF plus CAD, or Chief Architect files. Every set is licensed for one build at your build address. An engineer's review and stamp where required, a site plan, engineered floor and roof framing, mechanical and plumbing drawings and energy compliance are produced locally, as they are for any stock plan.
