Expanding Your Square Footage Seamlessly

When you love your neighborhood but have outgrown your house, a room addition is the ideal solution. EG Construction builds home extensions that integrate flawlessly with your existing architecture. Whether you are adding a new primary bedroom suite, expanding the kitchen, or building a second story, we handle the complex structural tie-ins required to make the addition look like it was part of the original build.

A successful addition requires careful engineering. The new foundation must be properly tied into the old one, the new roofline must pitch and drain correctly, and the new electrical and HVAC systems must be integrated without overloading the existing infrastructure.

We manage every aspect of the expansion, from trenching the new footings to matching the exterior stucco or siding perfectly. Our goal is to expand your living space while minimizing disruption to the rest of your home.

  • Window matching for architectural consistency

The Challenge of Tying In

The mark of a poorly built addition is a visible seam between the old and new structures. We pay extreme attention to the "tie-in." We lace new roofing materials into the existing roof, match the texture of the exterior stucco perfectly, and level the floor joists so there are no awkward steps or transition strips between the existing house and the new room.

Crucial Addition Considerations

Setbacks & Zoning

Before designing an addition, we must review city zoning laws, property line setbacks, and lot coverage limits to determine how far out or up you are legally allowed to build.

Foundation Matching

We evaluate your current foundation (slab or raised) and engineer the new foundation to match the height and prevent differential settling between the old and new structures.

System Upgrades

Adding square footage often requires upgrading your main electrical panel from 100 amps to 200 amps and evaluating if your current HVAC unit can handle the extra volume.

Roofing Geometry

We design the new roof pitch to shed water effectively away from the existing structure, avoiding the creation of "dead valleys" that trap water and cause leaks.

EG Construction Process
Our Construction Process

Clear Planning from Start to Finish

1
Consultation & Existing Review

We start by learning how the added space needs to function and reviewing the property constraints that shape the addition strategy.

2
Scope & Planning

We help define the remodel scope, including structural work, cabinetry, counters, plumbing, and electrical to reduce surprises.

3
Preparation & Demolition

Before demolition, we protect surrounding areas, set up dust control, and remove the existing kitchen carefully.

4
Rough Construction

This phase includes framing, structural changes, plumbing, electrical, and drywall prep for finishes.

5
Cabinetry, Counters & Finish Work

Cabinets, counters, backsplash, flooring, fixtures, lighting, and appliances are installed with attention to detail.

Frequently Asked Questions

Building out (a ground-level addition) is generally cheaper because you do not have to reinforce the existing walls and foundation to support the weight of a second story. However, building out requires available yard space and new foundation work.

A standard ground-floor addition typically takes 3 to 5 months of construction time, not including the architectural design and city permitting phases.

Yes, adding permitted square footage to your home will trigger a reassessment of the new addition by the county, which will increase your property taxes based on the value of the added space.

In most cases, yes. We can usually build the shell of the new addition while you live in the house, only breaking through the connecting wall toward the end of the project to minimize disruption.
