What we build
Home additions for Lindenwood homes
Lindenwood's housing stock pushes additions in a specific direction. The co-op complex is governed by a board, so any change to an attached unit needs board approval before it ever reaches the DOB, and alterations that touch a party wall, a shared roof, or the building envelope are often off the table entirely. For the attached one and two-family homes around the complex, you are still working between neighbors on a narrow lot, which means the rear yard is usually where the real square footage lives.
Zoning is the second constraint that shapes what is feasible here. Lindenwood's lots are governed by FAR, required rear and side setbacks, and a lot-coverage cap, and on attached homes much of that buildable area is already used. We start every project by reading your lot against the zoning to see how much floor area you have left, whether a rear extension fits inside the required rear yard, and whether a second story can be added without triggering setback or coverage problems with the attached units beside you.
From there the process is methodical: a measured survey of the existing structure, a feasibility check against FAR and setbacks, board approval where the co-op requires it, then DOB filing, construction, and sign-off. Because units sit wall-to-wall, we sequence work to protect shared structure and keep neighbors informed, and we keep the design within what the lot and the board will actually permit rather than promising space the zoning does not allow.
Rear extensions
Pushing into the rear yard is usually the most feasible addition on a Lindenwood attached home. We size the extension to stay inside the required rear setback and the lot-coverage cap so it clears DOB review.
Second stories
Where FAR and the building line allow, a second story adds bedrooms without touching the footprint. On attached homes we detail the work to respect the shared roofline and party walls with adjoining units.
Bump-outs
A modest bump-out can widen a kitchen or bath when a full extension would exceed coverage. It is often the most board-friendly option on tight co-op-adjacent lots.
ADUs
Where the lot and current rules support it, we look at accessory dwelling options such as a finished, code-compliant lower level or rear unit, planned around Lindenwood's setbacks and coverage limits.
