Adding a room, a second story, or a bump-out in New Jersey means new framing, foundations and beams that tie safely into the existing house — and sealed drawings for the permit. We design the structure for snow, wind, frost and seismic per the NJ Uniform Construction Code.
Home additions in New Jersey need sealed structural engineering: foundation and footing design, floor and roof framing, beams, and the connection back to the existing structure — all sized for New Jersey's snow, frost and wind.
The hardest part of an addition is the connection to what's already there — matching foundations, transferring loads, and making sure the existing structure can take the new demand. We evaluate the existing framing and design the tie-in, not just the new box.
Ground snow load on the new roof, footings below the ~36-inch frost line, design wind, and Seismic Design Category B all factor into the design. We engineer to the adopted 2021 IRC/IBC New Jersey code.

Absolutely. We provide the structural engineering to go with your architect's or designer's plans, or prepare the structural drawings directly.
Yes — including verifying the existing foundation and walls can carry the added floor, which is critical for a second story.
