Add Space Without Leaving The Home You Love

Sometimes the best next step isn't moving. It's making the home you already love work better for you.

At Scott Martin Homes, we help homeowners throughout Butler, Allegheny, Beaver, Armstrong, and Lawrence county create additions that blend seamlessly with the existing home while improving comfort, functionality, and everyday living.

As a family-owned builder, we don't just manage projects, we build relationships that last well beyond the final walkthrough.

Home Additions Designed Around Your Needs

Seamless Integration

A great addition should feel like it was always part of the home, not an afterthought. We match architectural details, materials, and flow to your existing home while navigating the permitting, zoning, and code requirements unique to additions, so the final result feels intentional from every angle.

Minimal Disruption

We understand that, unlike a new build, an addition happens while you're still living in your home. We plan and sequence our work to keep the disruption to your daily life as minimal as possible, so your home continues to feel like home throughout the process.

Quality Craftsmanship

Through a long-standing relationship with Lezzer Lumber, we only use premium grade materials. As a family-run business, Scott or Andrew is personally involved in every phase of construction, ensuring the quality of those materials carries through to the finished addition.

Organized Project Management

We believe the information gap between you and our build partners should be as short as possible. That's why we rely on tools like JobTread to bring the entire team together under one platform, keeping everyone aligned so no change or request is missed during construction.

Frequently Asked Questions

How Much Does A Home Addition Cost?

The cost of a home addition depends on the size, scope, and finish level you're after. Much like the home itself, the details in the cart matter as much as the size of it. A small bump-out or single-room addition will cost far less than a full second-story or multi-room expansion with high-end finishes. Once we understand your goals for the space, we can give you a much more accurate number to work with.

Will I Need To Move Out During Construction?

In most cases, no. You can continue living in your home throughout the addition process. We plan and sequence our work to minimize disruption, sealing off construction areas and keeping the site clean and considerate of your daily routine. Every project is different, so we'll walk you through what to expect for your specific situation before construction begins.

How Do I Finance A Home Addition?

We have long-standing relationships with local lending institutions that can help you secure a construction loan for your project. Because these lenders are familiar with home additions, they can guide you through the unique steps involved, like staged draws and inspections, that differ from a traditional mortgage. We're happy to make introductions and stay involved every step of the way.

Who Designs My Home Addition?

We highly recommend working with a local architect to design your home addition. This gives us the detail needed for accurate pricing, ensures your addition meets engineering and structural requirements, and keeps everything compliant with local building codes. We're happy to connect you with an architect we trust if you don't already have one.

What Areas Do You Build Home Additions In?

Based in Butler County, we build additions throughout Butler, Allegheny, Beaver, Armstrong, and Lawrence county. If you're unsure whether or not we can build in your community, we still encourage you to reach out.
