Home Addition in Springfield, VA
Springfield's 1960s–1980s split-levels and colonials were built on generous lots — often 0.3 to 0.5 acres — with room to build. When you've outgrown the house, adding on beats moving in this market. DFC designs and builds Springfield additions from permit to certificate of occupancy.
Springfield Home Additions
Springfield's housing stock makes it one of NoVA's best addition markets.
Springfield — primarily the 22150, 22151, 22152 and 22153 zip codes — is a Fairfax County community built out largely between 1955 and 1985. The dominant housing types are three-bedroom split-levels, four-bedroom colonials and some ranches. Most sit on 10,000–20,000 square foot lots in the interior of the county, away from the tighter urban lots you find in Falls Church City or Arlington.
That lot size matters for additions. A 300–500 square foot rear bump-out is feasible on most Springfield properties after checking setbacks. So is a second-story addition over an existing garage or one-story section. The structural complexity is manageable, the foundation conditions are generally known (poured concrete or block, depending on era), and Fairfax County's permitting process is one we navigate every month.
The most common Springfield addition requests we get: a primary bedroom suite addition over an existing garage, a rear kitchen bump-out to open up the main level, an in-law suite on a first-floor addition for an aging parent, and basement-up expansions. We assess which is feasible on your specific lot and give you real numbers before you commit to design fees.
