What Is a Second Story Addition?

A second story addition is the process of building a new upper floor on top of an existing single-story home. Unlike a room addition that extends out into the yard, a second story addition adds height — using the existing lot space of your home. This approach is highly practical on smaller lots where there simply isn't room to spread out.

Mechanically, the work involves evaluating the existing structural elements, foundation, and load-bearing walls to determine how much vertical load they can carry. In some cases, load-bearing wall changes are needed before the upper floor can be built. Once the existing build is ready, the existing roofline is lifted, the new upper-level framing is installed, and walls, windows, electrical, plumbing, and HVAC are all integrated.

The finished product is a fully functional upper floor that blends seamlessly with the rest of your existing structure. A well-executed second story addition creates usable rooms while preserving your outdoor living areas. Brother & Brother Builders handles each second story addition as a unique build — never a one-size-fits-all solution.
