OUR HOME ADDITION SERVICES

Every home addition is scoped and priced before we break ground. Done right, it's one of the highest-value investments you can make in your property.

Design + planning

Home additions require careful planning to ensure the new space looks and feels like it belongs. We guide layout, rooflines, exterior integration, and interior flow so the addition connects naturally to your home. Designers or drafters are coordinated when required.

Project Management

We manage scheduling, permits, inspections, and trade coordination from start to finish. Additions involve more moving parts than interior remodels, so clear communication is essential. You'll always know what phase we're in and what's coming next.

CONSTRUCTION + SITE CARE

Additions involve excavation, framing, and exterior work alongside interior construction. We protect existing structures, maintain organized job sites, and manage debris carefully so your home remains safe and livable throughout the build.

Cabinets + Storage

When your addition includes kitchens, bathrooms, or built-in storage, we install cabinetry designed to match or complement your existing home. Storage solutions are planned to maximize function without making the new space feel disconnected.

Plumbing

If the addition includes bathrooms, laundry, or wet spaces, we handle plumbing installation and extensions from existing systems. All plumbing work is completed to current code and coordinated carefully with framing and finish work.

Electrical + Lighting

We extend electrical systems into the new space, adding outlets, switches, and lighting where needed. Lighting is planned to match the function of the room while maintaining consistency with the rest of your home.

Flooring

Flooring in a home addition is selected to blend seamlessly with adjacent spaces or define the new area intentionally. We prepare subfloors properly and handle transitions so the addition feels like part of the original home.

Walls, Ceilings + Finishes

Drywall, paint, trim, and ceiling details are completed to match existing finishes or updated intentionally as part of a larger remodel. The goal is a finished space that doesn’t feel added on or out of place.

Structural + Framing

We handle foundations, framing, and structural connections required for your addition. This ensures the new space is built correctly, meets code requirements, and integrates safely with the existing structure of your home.

Countertops + Surfaces

We coordinate countertops and interior surfaces within the addition to match or intentionally transition from the existing home. Materials are selected for durability, consistency, and long-term use, creating a cohesive finished result.

Optional / Common Upgrades

Common upgrades include vaulted ceilings, large windows or sliding doors, skylights, custom built-ins, exterior patio connections, and energy-efficiency improvements to enhance comfort and long-term value.

Our Trusted Contractors + Suppliers

We partner with reliable subcontractors and quality suppliers to deliver consistent results on every project.

HOME ADDITION FAQs

Common questions about home addition costs, timelines, and planning.

Will the addition match the rest of our home?

That’s a priority. We design additions to blend with your home’s structure, rooflines, and finishes so the new space feels intentional, not like an afterthought.

How long does a home addition take?

Most home additions take several months from start to finish. Timelines depend on size, permitting, and complexity. We provide a clear schedule during planning so expectations are set early.

Can we live in our home during a home addition?

In most cases, yes. We plan construction to minimize disruption, though some phases may be noisier or require temporary adjustments. We’ll walk through what to expect before work begins.
