Basements & Additions
Basements & Additions in Atlanta, GA
Expand your living space — finished basements, home additions, and new square footage built to match your home.


More space, more value
Basement finishing converts an unfinished basement into usable living space by adding insulation, framed walls, drywall, flooring, lighting, and often a bathroom or wet bar. Home additions expand the home's footprint with new framing, roofline, and finish work tied into the existing structure. TopFlight Builders handles both throughout Greater Atlanta — from permits and framing through flooring and final finishes, designed to flow with your existing home.
