From prewar co-ops on the Upper East Side to loft conversions in Tribeca, we plan, permit, and build across Manhattan. One accountable team that knows board approvals, building rules, and how to work cleanly in an occupied building.
Building in Manhattan
Manhattan is the most demanding place to build in New York. Co-op and condo boards, alteration agreements, prewar structures, and elevator-only access all shape what a project takes. We handle the paperwork, the board requirements, and the on-site logistics so your renovation moves forward without friction, and without straining your building relationships.
Where we build in Manhattan
Cast-iron lofts, converted warehouses, and glass condos where landmark rules and building agreements shape every scope.
Prewar and postwar co-ops, high-rise condos, and pieds-a-terre where elevator access and board schedules drive the plan.
Classic prewar apartments, brownstones, and townhouses from the Upper East and West Sides up to Harlem and beyond.
How we work in Manhattan
Most Manhattan homes are co-ops or condos. We prepare the alteration agreement package, insurance certificates, and drawings your board needs, and we build within approved hours and house rules.
Century-old buildings hide surprises behind the plaster. We file the right DOB path, coordinate with your building engineer, and plan for old wiring, plumbing, and load-bearing walls before demolition starts.
No driveway and one service elevator. We schedule deliveries, protect common areas, control dust, and keep the hallways spotless so the building barely notices we are there.

Common questions
In almost every co-op and most condos, yes. Your board reviews an alteration agreement, drawings, and insurance before work begins. We prepare the full package and build to the approved scope and hours, so the process stays smooth.
Board review and DOB filing usually add a few weeks up front. Once approved, a kitchen or bath typically runs a few weeks and a full-apartment gut runs a few months. We give you a realistic schedule after we see the space and your building rules.
Yes. We work within approved hours, protect elevators and common areas, control dust with negative-air setups where needed, and keep hallways clean. Respecting the building is part of the job.
All of it, from the Financial District and Tribeca to the Upper East and West Sides, Harlem, and Washington Heights. Share your address and we will confirm and outline next steps.
