Navigating the board process in Carnegie Hill is one of the most consequential parts of any renovation. Our team prepares and manages the entire approval package — comprehensive architectural drawings, engineering reports, alteration agreement documentation, and insurance certificates — designed to satisfy reviewing architects, managing agents, and boards from the outset. We also manage all DOB filings, ACP-5 testing coordination, and LPC applications where required. Read more about our board approval and permitting services.

Pre-war kitchens were rarely designed for modern lifestyles — they barely fit one cook, let alone the appliances and layout a contemporary household requires. Gallery helps Carnegie Hill clients reconfigure layouts, upgrade plumbing and electrical systems, and integrate appliances with a design sensibility that honors your home's history. Pre-war kitchen renovations in this neighborhood typically range from $80,000 to $160,000+ depending on size, appliance package, and the extent of mechanical work required.

Whether you're renovating one bathroom or four, our team brings modern comfort into compact pre-war baths with unique designs for each — updated fixtures, concealed storage, and period-appropriate tilework, all while navigating structural and plumbing limitations. Bathroom renovations in pre-war apartments of this caliber typically fall between $45,000 and $90,000+ per bath depending on layout, tile scope, and custom fixtures.

From restoring existing built-ins to fabricating period-authentic cabinetry that matches original millwork profiles, our millwork team ensures cohesion throughout the home, offering practical storage that blends beauty with function. Custom millwork in pre-war apartments of this caliber typically ranges from $20,000 to $60,000+ depending on scope and profile complexity. Read our guide on what drives the cost of custom millwork.

Pre-war apartments built in the 1920s and 1930s were wired for a fraction of the electrical load a modern home requires. Knob-and-tube wiring is uninsurable and must be replaced. Steam risers in pre-war buildings often contain asbestos-containing insulation that requires ACP-5 testing and abatement before DOB permit filing. We help Carnegie Hill clients modernize infrastructure discreetly, concealing systems while ensuring compliance with current codes and co-op requirements. Full electrical rewire typically runs $50,000–$70,000+. HVAC installation runs $60,000–$100,800+. Learn more about HVAC for pre-war renovations.

Whether refinishing original parquet or installing reclaimed oak, we preserve the integrity of your pre-war home by selecting period-appropriate flooring that matches the original as closely as possible. In many high-rise buildings in Carnegie Hill, demo debris is removed by hand in buckets — unlike low-rise or townhouse projects where dumpsters are an option — which adds labor cost that rarely appears in preliminary estimates from less experienced firms.
