If you’re planning an apartment or townhouse renovation in New York City, the “who do I hire?” question usually lands in one of two camps. Two common design/construction methods are design-build and design-bid-build. Both approaches can produce a beautiful result. The difference is the project delivery method: how risk is managed, and how smoothly decisions travel from concept to construction. This is especially true when you’re dealing with a real budget, co-op/condo rules, board approvals, DOB filings, and the realities of working in older NYC buildings.

This guide breaks down the real-world differences so you can choose the model that fits your scope, timeline, and stress tolerance.
