This thoughtfully designed Colonial Revival carriage house garage plan blends traditional American architecture with modern-day functionality. Designed as a compact yet highly versatile structure, this plan is ideal for homeowners seeking a refined garage apartment, guest suite, home office, or accessory dwelling unit (ADU) that complements classic residential neighborhoods.

With its symmetrical façade, traditional siding, and upper-level living space, this plan works equally well as a backyard addition, alley-loaded garage, or standalone secondary structure.

Heated & Unheated Square Footage Breakdown

• Heated living area: 423 sq. ft. on the upper level
• Garage area: Approximately 500+ sq. ft. accommodating two vehicles

The separation between garage and living space provides privacy, safety, and noise control, making the upstairs area comfortable for daily use or overnight stays.

Upper-Level Study & Living Space

The upper floor is designed as a flexible open living area with a dedicated private study. This space can easily function as:

• A quiet home office or remote-work studio
• A guest retreat or overflow sleeping space
• A hobby room, art studio, or library
• A future conversion into a small efficiency apartment

A full bathroom serves the upper level, making the space fully self-sufficient and comfortable for extended use.

Garage Design & Vehicle Storage

• Garage capacity: Two-car garage
• Entry: Front-load configuration
• Doors: Traditional carriage-style overhead doors
• Foundation: Slab (with free foundation change options)

The garage level is ideal for daily parking, workshop use, or general storage. The clean structural layout keeps construction efficient while maintaining architectural integrity.
