Building up on a narrow lot
Adding a floor to a 14–16 foot wide rowhome takes more than framing. We check zoning height limits, the existing party walls and joists, and how the new stair and pilot house will fit before anything is drawn.
- Zoning check before design, with variance help if needed. See permits & zoning.
- Structural review of walls and joists for the new load
- Neighbor coordination for shared walls and roof access
- One team from drawings to final inspection
