The Upper West Side is defined by its classic pre-war co-ops — grand "classic six" and "classic seven" layouts built for large families, many facing Central Park West or Riverside Drive inside the Upper West Side/Central Park West and Riverside-West End Historic Districts. A full renovation here usually means reconfiguring formal, compartmentalized floor plans for modern family life while satisfying some of Manhattan's most conservative co-op boards.

WhiteStar General Contractors has renovated Manhattan pre-war buildings for over 20 years, and the Upper West Side is where reconfiguring a formal, compartmentalized classic layout into an open modern home is the core of the work. We prepare full board packages up front, handle the structural review that comes with removing prewar partition walls as part of a coordinated gut renovation, and manage unit-combination projects that are common across the neighborhood’s larger buildings.
Why Upper West Side Renovations Are Different From Anywhere Else in Manhattan
Classic layout reconfiguration
Original floor plans built around formal dining rooms, maid’s quarters, and separate staff stairs often need full reconfiguration through our interior renovation service to create the open kitchen-and-living layouts today’s buyers expect.
Some of the city's most conservative co-op boards
Full board packages — architectural drawings, engineer letters, insurance documentation, and a firm schedule — are standard, and approval timelines here tend to run longer than average.
Landmarked facades on Central Park West and Riverside Drive
Buildings within these historic districts require LPC review for any street-visible or facade change, which we file and manage alongside the interior scope.
Unit combination projects
Combining adjacent apartments — common in the neighborhood’s larger prewar buildings — requires structural review and unified plumbing and electrical planning across the combined footprint.
Brownstone and townhouse full renovations
Multi-floor brownstone projects frequently involve structural upgrades alongside full mechanical and finish-level work — see our approach in the Brownstone Renovation service.

Frequently Asked Questions
Can you reconfigure a classic six or seven layout into an open floor plan?
Yes — this is one of our most common Upper West Side project types, including structural review of the original partition walls before removal.
Do you prepare full co-op board packages for Upper West Side buildings?
Yes. We prepare drawings, engineer letters, and insurance documentation tailored to what Upper West Side boards typically require, and recommend starting the process 6–8 weeks ahead of construction.
Can you combine two adjacent apartments?
Yes — unit combinations are common in the neighborhood’s larger prewar buildings, and we manage the structural and plumbing coordination across both units.
Do you renovate brownstones as well as co-op apartments?
Yes. We handle full multi-floor brownstone and townhouse renovations, including structural and mechanical work — read more about our approach on the blog — in addition to individual apartment renovations.
