How We Work

We break room additions into clear phases: design and permits, structural prep, installation, and finishing. You'll know exactly what happens when.

1

Site Assessment & Permits

We inspect your lot, discuss your vision, and handle Los Angeles building permits. This ensures your addition meets local codes and zoning requirements.

2

Foundation & Framing

We pour foundations, set posts, and build the structural frame. Every joint is squared and reinforced to code, creating a solid base for your new space.

3

Mechanical & Electrical Install

Licensed electricians run wiring, HVAC technicians connect ductwork and systems. All work passes inspection before we close walls.

4

Drywall, Paint & Trim

Drywall hangers tape and finish walls. Painters apply primer and finish coats. Trim carpenters cut and install baseboards, doors, and cabinetry.

5

Final Inspection & Handoff

City inspector signs off on all work. We walk you through your new room, test systems, and ensure everything works perfectly.

You'll always know what's happening next—and when.

Our Services

We handle every aspect of room additions in Los Angeles—from structural work to finishing touches.

Bedroom & Guest Suite Additions

Bedroom addition project

Custom bedroom addition in Santa Monica with en-suite bathroom and large windows.

Los Angeles homeowners often need extra bedrooms for growing families or guest space. We design bedroom additions with proper ventilation, closet space, and electrical outlets. Each room meets LA building codes and connects seamlessly to your existing home.

Guest suites are popular in neighborhoods like Pacific Palisades and Brentwood. We can add bedrooms with private bathrooms, creating independent living areas that add both comfort and property value.

Kitchen & Dining Room Expansions

Small kitchens limit entertaining and daily comfort. We extend kitchens into adjacent spaces, creating open floor plans with room for islands and dining areas. Los Angeles homes often benefit from this reconfiguration—especially in neighborhoods where entertaining matters.

We manage gas, electric, and plumbing relocations safely. New kitchen expansions include proper ventilation for cooktops and seamless transitions between old and new finishes.

Backyard Structures & ADUs

Accessory dwelling unit construction

Permitted ADU in Los Feliz with separate entrance, kitchenette, and full bathroom.

Accessory dwelling units (ADUs) are legal in Los Angeles, offering rental income or family housing. We build compliant backyard units with all required utilities, egress, and parking.

Detached offices, guest houses, and hobby studios follow the same permitting process. Echo Park and Highland Park homeowners frequently add these structures. We handle lot surveys, setback requirements, and utility connections from start to finish.

Why It Matters

A well-built room addition increases home value, improves livability, and solves space problems without moving.

Proper Permitting & Code Compliance

Los Angeles building codes evolve. We stay current on seismic requirements, energy standards, and setback rules so your addition passes inspection.

Unpermitted work can create problems when you sell or renovate later. Our permits protect you and your investment. We submit plans to the city, attend inspections, and handle corrections if needed.

Built to Last

We use quality materials and proven construction methods. Framing is squared, foundations are reinforced, and electrical systems are properly sized. Your new room won't settle, leak, or develop gaps over time.

A room addition should feel like part of your home, not a temporary addition.

Serving Los Angeles and Surrounding Areas

We work throughout Los Angeles County, from the coast to the San Fernando Valley.

Local Knowledge, Professional Standards

Los Angeles has unique building challenges: seismic zones, solar ordinances, and dense neighborhoods with parking restrictions. We understand local permitting, HOA requirements, and which inspectors need clear documentation. Our experience spans Westwood, Koreatown, Long Beach, and everywhere between.

Whether you're in a hillside home requiring foundation engineering or a modest craftsman needing careful lot line management, we handle the specifics. We coordinate with neighbors, manage city inspections, and keep your project moving forward even when unexpected issues arise.
