South Plainfield homes and their basements
South Plainfield in Middlesex County is a classic post-war suburb of Capes, ranches, and split-levels. Many homes are on original roofs from the 1990s and original bathrooms from the 1960s, and they are ready for both.
Capes and the family room they're missing
Many South Plainfield Capes were built with a small living room and no family room. A finished basement gives you that space without an addition. The main planning issue in Capes is usually the main beam and ductwork running down the middle, which we box into clean soffits.
Ranches with full-footprint basements
A ranch's basement runs under the entire house, so it's often 1,200 square feet or more of potential living space. That's enough for a family room, a bedroom, a full bath, and storage.
Split-level lower levels
Split-levels in South Plainfield often have a lower level that is half above grade plus a true basement below it. The above-grade walls get real windows, which makes egress and daylight easier. We finish both levels as one project.
