Coastal Carriage House Garage Apartment with Compact Upstairs Living
Designed for efficiency, flexibility, and timeless curb appeal, this Carriage House / Garage Apartment house plan delivers a smart solution for homeowners seeking additional living space without expanding their primary residence footprint. With 448 square feet of heated living space positioned above the garage, this plan is ideal for use as an ADU, guest suite, casita, or income-producing rental.
Architecturally rooted in Coastal Traditional styling, the exterior features clean lines, balanced proportions, and classic horizontal lap siding—a durable and low-maintenance material commonly used in coastal and suburban environments. The result is a structure that blends naturally with primary homes while standing confidently as a fully functional secondary dwelling.
Thoughtful Two-Story Layout with Clear Separation
This carriage house design separates living and utility spaces vertically, offering privacy and flexibility that single-story accessory structures often lack. The garage level serves as secure storage or parking, while the upper floor functions as a complete living suite.
- Heated living area: 448 sq. ft. on the upper level
- Structure type: Detached garage apartment / ADU
- Access: Exterior staircase leading to private entry
Upper-Level Living Space
The upstairs layout is efficient yet comfortable, designed to feel open without wasted square footage. Natural light enters from multiple elevations, creating a bright and welcoming interior environment suitable for both short-term and long-term use.
- Open living area adaptable for lounging, dining, or work-from-home use
- Compact kitchenette layout supporting independent living
- Conventional ceiling heights for cost-effective construction
Bedroom & Bathroom Configuration
The plan includes one bedroom and one full bathroom, making it ideal for solo occupants, couples, or visiting guests. The bedroom is proportioned to accommodate standard furniture layouts while maintaining circulation efficiency.
- Private bedroom with space for closet storage
- Full bathroom positioned for convenient access from all living areas
Garage & Utility Level
The ground level is designed as a compact garage footprint, suitable for storage, workshop use, or small-vehicle parking depending on local zoning allowances. This makes the plan especially attractive for homeowners seeking flexible utility space beneath livable square footage.
- Detached garage configuration
- Front-facing access ideal for alley-load or rear-lot placement
- Efficient structural grid for cost-controlled construction
Coastal Traditional Exterior Design
This plan’s exterior reflects classic Coastal Traditional principles—simplicity, balance, and long-term durability. The horizontal siding exterior offers a clean visual profile while resisting the wear associated with humid or coastal-adjacent environments.
- Horizontal lap siding for timeless appeal
- Balanced window placement for symmetry
- Compact roof form for reduced construction complexity
Coastal carriage house designs like this are frequently used as secondary dwellings in beach towns, suburban neighborhoods, and resort-style communities. For broader context on how detached accessory buildings are shaping modern residential design, see this industry overview on ArchDaily.
