A typical home addition in Alpharetta takes 3 to 6 months from groundbreaking to completion, depending on the size and complexity of the project.

Weather-dependent stages like foundation work and roofing can shift the timeline slightly, but we build contingency into every project schedule and keep you informed throughout the process.

In most cases, yes — you can stay in your home while we build your addition.

The feasibility depends on the location of the addition relative to your living spaces, and we'll discuss the best approach for your situation during the planning phase.

Home additions typically deliver a strong return on investment, especially in Alpharetta's competitive real estate market where additional square footage is highly valued by buyers. Master suite additions and kitchen expansions tend to deliver the highest ROI, often recouping 60-80% of the investment at resale. Beyond the financial return, a well-designed addition increases your home's livability and marketability for years to come.

We source materials from the same manufacturers as your existing home whenever possible and use professional color-matching technology to ensure a seamless blend. For homes with James Hardie siding, custom stone veneer, or brick, we work with specialty suppliers to find exact or near-exact matches. Our goal is to make the addition look like it was part of the original construction, not a tacked-on afterthought.
