Astoria home additions

Most of Astoria sits on narrow lots in attached brick row houses and small multi-family buildings, with party walls shared on one or both sides. That shapes everything about an addition here. A rear extension or a bump-out is usually the most feasible move, because adding width is rarely possible when neighbors abut your side walls. We start by reading your zoning district, then check how much floor area and lot coverage you have left before deciding what the lot can actually hold.

Queens zoning controls the envelope through FAR, required rear yards, and side setbacks, and many Astoria lots are already near their FAR ceiling. A rear extension has to preserve the minimum rear yard, a second story has to stay inside height and sky-exposure limits, and lot coverage caps how far you can build into the yard. When the numbers are tight, an ADU in an existing garage or a cellar conversion can add usable space without breaking the envelope. We map these constraints first so you are not designing something the DOB will reject.

Approvals in Astoria often involve more than the DOB. Pre-war co-ops and some condo buildings require an alteration agreement and board sign-off before any work starts, and party-wall changes mean coordinating with the adjoining owner. We handle the filings, the structural details for shared walls, and the documentation boards ask for, so the project moves cleanly from permit to final inspection.
