Also included · Garage conversions
Turn your garage into living space.
Your garage is space you already own. We turn it into a comfortable living area that feels like part of your home.
A converted garage should feel like part of your original floor plan, not a closed-in storage room. We match the exterior finishes, make the most of the ceiling height and add windows for natural light. We also solve the technical parts early, such as insulating the concrete slab, so the new room is comfortable all year and adds real value to your home.
The technical work
Leveling the floor, moisture barriers and dedicated heating and cooling.
Matches your home
Trim, flooring and exterior finishes that match the rest of your house.
More than a cosmetic update
A garage conversion needs real structural and climate work, not just new paint. We connect the new room to your home's systems and solve the insulation and exterior details, so it feels like it was always part of the house.
Free consultation →- Slab insulation, moisture protection, and heating and cooling, done right.
- An exterior that blends in with the rest of your house.
- Zoning and permits handled, so the new space is fully approved.

All service areas → What is the difference between an ADU and a Junior ADU?
An ADU is a detached or attached accessory dwelling up to 1,200 square feet with its own kitchen and bathroom. A Junior ADU (JADU) is smaller, created within the walls of your existing home (like a garage or spare wing), and can share a bathroom with the main house while having its own kitchenette and entrance.
Can I build an ADU on my property if I have a small backyard?
In most cases, yes. Local zoning laws have become more flexible, allowing ADUs even on smaller lots as long as specific setback requirements are met. During our initial feasibility study, we analyze your property's dimensions to design a unit that maximizes your available space without making your yard feel crowded.
Do ADUs have their own utility meters for electricity and water?
They can, but it is not always required. You can choose to have separate meters for a completely independent setup, ideal for long-term guests, or you can tie the unit's utilities into your main home's existing systems. We handle all the plumbing and electrical engineering to ensure both structures have consistent, reliable power and water.
How does an ADU impact my property value and taxes?
An ADU is a significant investment that typically increases your property's market value by adding functional square footage and potential rental versatility. While it may lead to a modest reassessment of your property taxes based on the value of the new construction, it does not trigger a full reassessment of your entire home's original value.
How do you ensure privacy between the main house and the ADU?
Privacy is a cornerstone of our design process. We strategically place windows, entrances, and outdoor living areas to prevent direct lines of sight between the two dwellings. We also use professional landscaping and sound-dampening materials to ensure both spaces feel private, quiet, and entirely independent.
Will you handle the specific ADU permits required by my city?
Absolutely. ADU regulations can be complex and vary significantly by neighborhood. As a design-build firm, we take full responsibility for the entire permitting process, ensuring your unit is fully compliant with local height restrictions, fire safety codes, and structural mandates before construction ever begins.
Will my converted garage feel like a "real" room or just a finished garage?
Our goal is complete architectural integration. By raising the floor to match the house level, using consistent ceiling treatments, and matching the interior trim and flooring of your main home, the space will feel like an original, high-end part of your residence.
How do you handle the temperature control in a former garage?
We don't just add a heater; we treat the space as a new thermal envelope. This includes insulating the concrete slab, using high-R-value wall insulation, and either extending your home's HVAC system or installing a dedicated, high-efficiency climate control unit for year-round comfort.
Do I need a permit to convert my garage into a living space?
Yes. Converting a non-habitable space into a living area requires specific building, electrical, and plumbing permits. We handle the entire application process, ensuring your new room meets all fire safety, ventilation, and ceiling height codes for legal occupancy.
What happens to the garage door and the exterior look?
We remove the garage door and replace it with architectural elements that match your home, such as custom windows, French doors, or matching siding. This ensures the exterior of your home maintains its curb appeal without looking like a "patched-over" garage.
Is it possible to add a bathroom or kitchenette to the conversion?
Absolutely. Many clients convert garages into self-contained guest suites or ADUs. During the design phase, we assess your home's existing plumbing and drainage lines to determine the most efficient way to integrate a full bathroom or functional kitchenette into the layout.
Will converting my garage decrease my home's resale value?
In high-demand areas, adding high-quality, climate-controlled square footage typically increases home value. We focus on ensuring the conversion is permitted and architecturally seamless, which protects your investment and makes the extra living space a verified asset during a future sale.
