From Underused Garage to Beautiful, Livable Bonus Room

Scope: When the homeowners at this Brentwood property wanted to unlock the potential of their detached garage, Carey Bros. Design & Build Remodeling delivered a full transformation—turning an underutilized structure into a comfortable, light-filled bonus room that feels like a natural extension of the home.

The Vision: The goal was to create flexible living space without expanding the home’s footprint. The new room needed to feel permanent, integrated, and architecturally consistent with the existing residence—while meeting today’s energy, safety, and comfort standards.

The Transformation: Our team at Carey Bros. Design & Build Remodeling managed the project from design through completion, including:

• Structural conversion of the garage into conditioned living space
• Removal of the overhead garage door and installation of a new window wall to bring in natural light
• Widened entry door for improved access and flow
• New framing, insulation, drywall, and interior finishes to create a polished, residential feel
• Luxury vinyl plank flooring for durability and style
• Mini-split HVAC system for efficient, year-round comfort
• Updated electrical with new lighting, outlets, ceiling fan, and life-safety systems
• Exterior refinements, including stucco patching and foam trim, to seamlessly match the existing home

Every detail—from window proportions to finish transitions—was carefully planned so the new space feels like it was always meant to be there.

The Result: What was once a storage-only garage is now a bright, versatile bonus room—ideal as a home office, guest suite, studio, or media space. The project not only increased the usable square footage of the home, but also enhanced its overall value and livability.

This conversion is a great example of how thoughtful design and precise construction by Carey Bros. Design & Build Remodeling can completely redefine how homeowners experience their space—without the cost or disruption of a full addition.
