More Space, Done Right

When your family outgrows your home, you have two choices: move, or build. G&S Restoration Group makes building the better option with expert room additions, dormers, and home extensions that blend seamlessly with your existing structure — matching the roofline, siding, and architectural style so it looks like it was always there.

We handle every phase: architectural coordination, permits, foundation, framing, roofing, siding, electrical, plumbing, insulation, sheetrock, and finishing. One contractor, one timeline, one number to call.

What We Handle

Room Additions

Single-room or multi-room additions — bedrooms, family rooms, home offices. New foundation, framing, and full interior finishing.

Dormers

Shed, gable, and hip dormers that add headroom, natural light, and usable square footage to your attic or upper floor.

Garage Extensions

Expand your garage for additional vehicles, workshop space, or convert it into living area with a new detached or attached garage.

Second Story Additions

Add an entire floor to your home. Structural engineering, foundation reinforcement, and complete construction from floor to roof.

Bump-Outs

Small-footprint extensions (4-10 feet) that expand a kitchen, bathroom, or bedroom without the cost of a full addition.

In-Law Suites

Self-contained living spaces with bedroom, bathroom, kitchenette, and private entrance. Multigenerational living done right.

Frequently Asked Questions

How much does a room addition cost?
Room additions typically run $150-$300 per square foot depending on finishes, plumbing, and complexity. A 200 sq ft bedroom addition might be $30,000-$60,000. Dormers are typically $15,000-$40,000 each. We provide detailed estimates after a site visit.
 
Yes — all room additions, dormers, and structural changes require building permits. We handle the entire permit process including architectural drawings, structural engineering, and inspection scheduling.
 
In most cases, yes. We seal off the construction area from your living space with dust barriers. There will be some noise and disruption, but you’ll have full use of your existing rooms throughout the project.
 
That’s our top priority. We match your existing roofline, pitch, siding material, window style, and trim profiles. When we’re done, the addition should look like it was part of the original design — not an afterthought.
