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.
