Garage Apartment Plan with 1 Bedroom & 2-Car Garage | 660 Sq Ft Living Space

The Haverton Bridge 3670 is a versatile two-story garage apartment plan offering 660 sq ft of heated living space atop a robust 528 sq ft garage. Designed with a 30 ft width and 33 ft depth, this building occupies a compact footprint that fits easily on smaller lots or behind existing structures while maintaining a total building height of 21 ft 6 in.

The second-floor living quarters are accessed via an efficient layout that maximizes every inch of the 660 sq ft floor plan. A central keeping room serves as the primary social core, providing direct access to the living areas. The private master suite is positioned to ensure quiet separation, featuring an attached full bathroom that creates a self-contained environment for guests or long-term tenants.

Convenience is integrated through the inclusion of a dedicated second-floor laundry area, preventing the need to traverse between levels for household chores. An attached 140 sq ft deck extends the usable living space outward, facilitating outdoor access directly from the upper level. The interior maintains a consistent 8 ft ceiling height throughout the living quarters, promoting energy efficiency and thermal control.

Structural integrity is provided by 2x6 wall framing and a slab foundation, ensuring a durable build suitable for diverse climates. The roof features a 5:12 pitch, contributing to a clean exterior profile. The side-load garage configuration provides space for two vehicles and includes a 9 ft ceiling height, allowing for significant vertical storage or workshop utility without impacting the building's front elevation.

Key Features: 1 bedroom, 1 bathroom, 660 sq ft living area, 2-car side-load garage, 5:12 roof pitch, 8 ft ceiling height, second-floor laundry, 140 sq ft deck, 2x6 wall framing, slab foundation, accessory dwelling unit utility.

Review image
JoAnne and the entire staff was extremely helpful and patient with us while we decided between 2 homes. This home has outstanding curb appeal and a great layout perfect for us. I work from home so having the home office off the foyer is fantastic. I converted the wet bar into a storage closet for my office. We also extended the laundry room into the porch and created a multipurpose laundry/mud room. I would buy from archival designs again and again.

It took almost a year to pick a plan. Since my husband and I retired a few years ago we wanted this last house had to have everything we wanted and needed. The kitchen is my favorite part of the house. I can see what’s happening in my neighborhood through my kitchen window and watch my husband garden in the back yard. Our children think we made a smart decision when we picked this house for our senior years.

We’ve had an amazing experience with our new home and are excited to be moved in. The customer service we received during our modifications was exceptional. We are loving the open layout of the kitchen and family room. It feels spacious and I’m already planning on hosting holiday dinners at home. We recommend Archival Designs to anyone interested in building the home they’ve always wanted!

We absolutely adore the Kildare Place house plan. Made some modifications to make this home ours! Our house is the talk of the neighborhood. We host big parties every holiday and still get compliments from our friends and family. We searched for months and looked through hundreds of floor plans and this one had almost everything we wanted, and with the help of the great staff at Archival Designs we got exactly what we wanted!

FAQ

Can I modify this Garage Apartment Plan with 1 Bedroom & 2-Car Garage | 660 Sq Ft Living Space now or later?

Absolutely. We offer in-house modification services to adjust layouts, room sizes, or expand garages before purchase. If you prefer to make adjustments during the construction phase, purchasing the CAD file package allows your local builder or architect to make on-site changes. Simply click 'Request a Modification' for a free quote.

How much will it cost to build this Garage Apartment Plan with 1 Bedroom & 2-Car Garage | 660 Sq Ft Living Space and why aren't exact costs shown? 

Construction costs vary significantly ($150–$300+ per sq. ft.) based on your location, material choices, and local labor rates. Because site preparation and regional codes differ, it is hard to provide a universal cost always.

Will this Garage Apartment Plan with 1 Bedroom & 2-Car Garage | 660 Sq Ft Living Space fit my lot, and can I add a basement or flip the layout?

You can check the 'Modifications' tab for width and depth requirements. To fit your site's orientation, most plans are available in a 'Right Reading Reverse' (mirrored) format. We also offer slab, crawlspace, and basement foundation adjustments for every design.

Do your plans meet building codes in my area and do I need a professional stamp?

Our plans meet or exceed national IRC (International Residential Code) standards. However, due to varying local requirements regarding seismic, wind (hurricane), or snow loads, house plans do not come with a professional architect’s or engineer’s seal. Most municipalities require a review and stamp by a local licensed professional to obtain a building permit.

Are plumbing, HVAC, and mechanical drawings included?

We provide the architectural and schematic electrical framework, but HVAC and plumbing layouts are not included. Because local codes and climate-specific systems vary significantly across the country, these are best finalized by your local subcontractors to ensure your home’s systems are optimized for your specific site and energy requirements.

Why should I choose Archival Designs and are the plans guaranteed?

With over 40 years of experience, Archival Designs provides high-quality, builder-ready designs that balance aesthetic elegance with structural integrity. We offer a Best Price Guarantee, a 10% discount for military and first responders, as well as builder discounts for life. And loyalty perks for pro builders. All plans are designed to comply with the IRC codes at the time of their creation. Learn more about our Best Price Guarantee.
