Whether you are planning a new construction, remodeling or a new renovation project, our consultants will save you time and money during the procurement process, from submission to approval.
Turning a residential property into a commercial space (or converting a commercial building back to residential) is one of the most profitable moves a property owner can make in New York City. But without the right property conversion professionals in NYC, the process can become a maze of zoning reviews, DOB filings, and costly delays that may stall your project for months.
We guarantee that the applications are presented correctly and we carry out a previous detailed review of the construction plans.
