Westchester County, NY Office Construction Contractor

Ariel Construction delivers commercial office build-outs, tenant improvement (TI) projects and workplace renovations across New York, Texas and Florida — always inside an existing shell or occupied floor, never ground-up.

An office build-out lives or dies on schedule certainty. Every day past your lease commencement date is rent you pay on space you can't occupy, so we build the construction schedule backward from your move-in date and hold it with fixed pricing, a single point of contact and daily on-site supervision.

Our office construction teams handle full interior fit-outs: demolition, metal stud framing and drywall partitions, glass front offices, acoustic and open ceilings, electrical and data rough-in, HVAC distribution and rebalancing, sprinkler relocation, millwork, flooring, paint and final furniture coordination. We manage landlord approvals, building department filings, COI requirements, freight elevator scheduling and after-hours work rules in Class-A buildings.

We work directly with owners, tenants, brokers, architects and workplace strategists — from a 2,500 SF suite refresh to a 60,000 SF multi-floor headquarters relocation.

In Westchester County, New York we handle the full interior scope — demolition, framing and drywall, ceilings, electrical and lighting, HVAC distribution, plumbing, sprinkler modification, millwork, flooring, tile, paint and final finishes — plus permitting, expediting, landlord approvals and inspections. Our Westchester County, NY office crews work in Yonkers, White Plains, New Rochelle, Scarsdale, Rye, Mount Vernon, Harrison and every surrounding community, including occupied spaces phased around business hours.

Whether you are a property owner repositioning an asset, a tenant working against a lease commencement date, a broker protecting a deal or a national brand rolling out a prototype, you get one point of contact, weekly reporting and a price locked before we mobilize. We do not do ground-up construction — commercial interiors are all we build.
