New Layouts Within an Existing Brooklyn Building
Opening rooms or replacing utilities in a brownstone can affect original stairs, woodwork, and structural framing. We review the design with your architect and plan how to build around features you want to keep.
In multifamily properties, we coordinate unit work with shared systems and occupied areas. For designated properties, we also work with your architect or preservation professional on the required review.

Brooklyn Construction Questions
When should I contact Bau about a renovation?
You can contact us with an early idea or developed plans. We can discuss the building, proposed work, construction costs, and sequencing.
How do you develop the renovation budget?
We discuss the improvements you want and your spending expectations, then review the property and any available plans. We estimate the work, explain amounts set aside for unselected products, and identify repairs needing investigation. For a multifamily program, we organize costs by work package or phase.
Can original brownstone features stay?
Often. We review the features you want to keep, their condition, and the work beside or behind them. We plan protection or repair around the renovation.
Can you renovate an occupied multifamily property?
Yes. We plan access, protection, shutdowns, phasing, and resident notices with management. The work and required protections determine which areas can remain occupied.
How do you manage the schedule?
We plan construction around approvals, product lead times, site access, and inspections. We tell you when decisions are needed and explain changes to the timing.
Does Bau handle permit applications in Brooklyn?
Yes. We coordinate drawings with licensed professionals, submit permit applications, and work with city agencies. For designated properties, we also coordinate preservation review. We obtain the necessary approvals before construction begins.
