Home Additions

Home Additions Designed To Disappear Into Your Home

Home additions in Long Beach and the South Bay, engineered to grow with your family and disappear into your existing home. We expand the right way with permitted plans, clean structural transitions, and finishes that match what you already love about your house.

Our Approach to Adding Space

Grow your home without losing what makes it yours.

A home addition is the most permanent change you can make to a house, which is why we treat it as architecture, not square footage. Every Urban Construction addition starts with a structural review of the existing home, an honest feasibility conversation, and a design that respects the original roofline, scale, and rhythm of your facade.

Whether you are adding a primary suite, a second story, a kitchen bump-out, or a sun-drenched family room, we coordinate architecture, engineering, and construction under one accountable team. That means one phone number, one schedule, and one budget from feasibility through final inspection.

We build for South Bay families who plan to stay in their homes for the next decade or longer. Material choices, mechanical sizing, and structural detailing all reflect that long horizon, so the addition still looks and performs beautifully years after the dust settles.

Benefits

Why Homeowners Choose To Add Instead Of Move.

  • Stay where you love. Add the square footage your family needs without selling, moving, or restarting your commute, schools, and neighborhood roots.
  • Add long-term value. A well planned addition increases usable space and resale value far beyond a quick cosmetic remodel.
  • Built to blend. Roofline, siding, trim, and interior finishes are matched to the original home so the addition reads as part of the architecture, not a bolt-on.
  • Predictable budgets. Fixed line-item pricing, locked allowances, and clear change-order rules so you know what you are paying for before we swing a hammer.
  • Live in your home while we build. Phased construction, dust walls, and protected entries keep your family comfortable during the project.

Our Home Addition Services

Every kind of addition, end to end.

Second-Story Additions

Second-Story Additions

When the lot is tight, build up. We handle structural engineering, foundation reinforcement, new stairs, and roof re-framing so a second story lands cleanly on the existing footprint. The result is a true second floor with full-height ceilings, code-compliant egress, and a roofline that looks original to the home.

Primary Suite Additions

Primary Suite Additions

A dedicated primary bedroom, spa-style bath, and walk-in closet, designed as a quiet wing of the house. We site the addition to capture light, protect privacy from neighbors, and keep mechanical runs short so HVAC, plumbing, and electrical are efficient and easy to service for decades.

Kitchen & Dining Bump-Outs

Kitchen & Dining Bump-Outs

Push the back wall out four to twelve feet and the whole house changes. We add the structure, windows, and slab work, then coordinate with our cabinet and stone shops so the new footprint flows into a kitchen and dining area that finally fits how you cook, host, and live.

Family Room & Sunroom Additions

Family Room & Sunroom Additions

Open, light-filled living additions that connect the home to the backyard. Large sliders, vaulted ceilings, and integrated indoor-outdoor transitions create a true gathering space, not a closed-off bonus room, while still meeting Title 24 energy and structural requirements.

Garage Conversions & Bonus Rooms

Garage Conversions & Bonus Rooms

Convert an attached garage or unfinished bonus space into a home office, gym, playroom, or guest suite. We address foundation, insulation, headroom, egress, and HVAC so the new room performs like the rest of the house, not a glorified storage space with carpet.

How It Works

How Your Home Addition Comes Together.

  1. 01

    Feasibility & Site Walk

    We walk your lot, measure the existing structure, review setbacks and easements, and confirm where an addition can actually go before any drawings begin. You leave the first meeting with a realistic scope, not a wish list.

  2. 02

    Design & Structural Planning

    Architectural drawings, structural engineering, and Title 24 energy calcs are produced together so the design we price is the design we build. You see floor plans, elevations, and a fixed line-item estimate before signing.

  3. 03

    Permits & City Coordination

    We prepare the permit package, submit to your local building department, respond to plan-check corrections, and pull all required trade permits so your project is fully legal and inspection-ready from day one.

  4. 04

    Site Prep & Protection

    Dust walls, floor protection, temporary weather seals, and a clear path for the crew. We protect the part of the home you keep living in and stage materials so daily life can continue around the work.

  5. 05

    Foundation, Framing & Tie-In

    New footings, slabs, framing, and the critical tie-in to the existing structure. This is where additions live or die, and our framers specialize in matching old framing to new without telegraphing the seam at the finish stage.

  6. 06

    MEP, Insulation & Drywall

    Electrical, plumbing, HVAC extensions, insulation, and drywall, coordinated and inspected at each rough phase. We size new mechanical loads against your existing systems so panels, water heaters, and HVAC are not silently overwhelmed.

  7. 07

    Finishes & Punch List

    Flooring, trim, paint, cabinetry, and fixtures, executed by the same finish carpenters who built our portfolio homes. We finish with a documented punch list and a final walk-through, not a vague handoff.

Structural Tie-In And Foundation Review

Every addition starts with the part you never see. We open a small area of the existing wall and foundation, document framing conditions, and have our structural engineer specify exactly how the new structure ties to the old, so loads, shear, and seismic forces are handled correctly.

  • Matching foundation depths and reinforcement so the new slab moves with the old, not against it.
  • Engineered beams and headers at the connection wall so existing ceilings stay level over time.
  • Seismic upgrades and shear paths designed to current California code at every tie-in point.

The payoff is an addition that does not crack, sag, or telegraph its seam, even ten or twenty years after the paint dries.

Permits, Setbacks, And City Coordination

Long Beach, Lakewood, Torrance, Manhattan Beach, and every city in the South Bay has its own setback rules, height limits, lot coverage maximums, and historic overlays. We confirm what your lot allows before design starts, then carry the permit package through plan check on your behalf.

  • Lot coverage, FAR, and setback analysis tied to your specific parcel and zoning district.
  • Title 24 energy compliance, structural engineering, and Cal Green calcs prepared with your plan set.
  • Plan-check responses, revisions, and trade permits managed by our team, not handed back to you.

We are not the city permitting office, and permit requirements can change. We help you understand the process, prepare the right documentation, coordinate with the appropriate city departments, and navigate review and inspections based on your specific project.

Living In Your Home During Construction

You should not have to rent a second home to remodel the one you live in. Our PM-led job sites are planned around the parts of the house your family still needs every day, with clear protection, predictable hours, and weekly schedule updates.

  • Sealed dust walls and floor protection separating the work zone from your daily living space.
  • Coordinated utility shut-downs scheduled in advance so power, water, and HVAC are only down when needed.
  • One project manager as your single point of contact, with weekly check-ins and a shared schedule.

The result is an addition that grows your home without taking over your life while we build it.
