General contracting and interior renovation

The team that restores your façade can renovate your lobby and interiors too.

Banu works as a general contractor across New York City and Long Island, in commercial and institutional buildings and in residential common areas. That covers lobby and hallway renovations, office and retail interiors, and the building improvements that go with a façade or roof program. Interior jobs are managed, reported on and closed out the same way as the work on the wall.

Why run the interior work with us

  • One schedule for the whole building.

    When a lobby renovation happens while the façade is being restored, the sidewalk shed, the deliveries and the noise get planned once instead of twice.

  • Work phased around the people inside.

    We renovate area by area, with dust and noise controls in place before work starts.

  • Field questions go to your architect.

    When what we find on site doesn't match the drawings, we raise it with your architect or engineer before building anything differently.

  • A clean close-out.

    The punch list finished, permits signed off and warranty documents handed over in one package.

Permits and approvals

DOB permits. Interior work that changes layouts, plumbing, electrical or fire protection generally needs a Department of Buildings permit. Your architect or engineer files the drawings, and we work from the approved set.

Landmarked buildings. If the building is an individual landmark or sits in a historic district, interior work that needs a DOB permit also needs a Landmarks Preservation Commission permit before it starts. Your architect files for it, and we build to whatever the permit allows. Landmark restoration →

Questions about general contracting

Do you take on interior-only projects?

Yes. We do commercial and institutional interiors and residential common areas, on their own or as part of a larger building program. When the interior work runs alongside façade or roof work, one team handles both on a single schedule.

Can you work from our drawings?

Yes. Send the drawings and specs, and we'll come back with a proposal covering scope, clarifications and a schedule.

Can the building stay open while you renovate?

In most cases, yes. We phase the work so residents, tenants and staff keep a safe way through, and we schedule the loudest work for the hours the building agrees to.

Who files the permits?

Your architect or engineer files the drawings with the Department of Buildings. We pull the work permits as the general contractor, keep them current while the job runs and close them out at the end.

Let's talk about your building

Have a set of drawings?

Send them over. We'll read them against the building and come back with a scope and a schedule.
