Brooklyn's housing stock ranges from 19th-century brownstones to new-construction condo buildings, and a general contractor working across the borough needs to plan differently for each. Illyrian Group Corp runs general contracting and gut renovation projects in both, the home renovation work Brooklyn's housing stock actually calls for, with a scope built around what's in the building, not a one-size template.
Brownstones and limestones bring their own logistics: no freight elevator, no loading dock, and often a designated historic district overlay that adds a Landmarks review step for anything visible from the street. Condo and multi-family buildings trade that constraint for building-management protocols closer to what we see in Manhattan. We scope the project around whichever reality your building actually has, the same way any New York contractors worth hiring should.
A common Brooklyn project for us is a parlor-floor brownstone that's been divided into rental units and needs to come back to a single-family layout, or a full-floor renovation that keeps the building's original detail while modernizing the systems behind the walls. We walk the property first, confirm what's structural versus cosmetic, and only then put a number and a schedule in writing.

Brooklyn Home Renovation Tiers: Standard, Mid-Range, and High-End
Brownstone parlor floors and new-construction condo units call for different specs. We help you land on the right one for the building and your budget.
Standard
Contractor-grade finishes: laminate or stock tile flooring, builder-grade cabinetry, and code-minimum lighting. Common for a rental unit inside a multi-family brownstone.
Mid-Range
Semi-custom cabinetry, engineered hardwood or porcelain tile, quartz counters, and restored or replicated period trim. Where most owner-occupied parlor-floor renovations land.
High-End
Full custom millwork matching original brownstone detail, exposed brick restoration, natural stone counters, and wide-plank hardwood. Common in a full-building brownstone restoration.

What Can Complicate a Brooklyn Home Renovation
- Party walls and joist spacing. Brownstones share structural walls with neighboring buildings, which affects how we sequence demo and any structural work.
- No freight elevator or loading dock. Debris comes out through the front or rear yard, so dumpster placement and street-parking permits need to be arranged before demo.
- Landmarks Preservation Commission review. Park Slope and Brooklyn Heights sit inside historic districts, adding a review step for street-visible exterior work.
- Floor-combining structural work. Turning two floors into a duplex requires a new stair opening, structural engineering, and DOB permits filed together.
- Pre-1978 lead paint testing. Many Brooklyn brownstones predate 1978 and may require lead testing and EPA Lead-Safe work practices before demo.
- DOT street-access permits. Dumpster placement on a Brooklyn block usually requires a permit from the city, which we factor into the schedule up front.

A 1-Year Workmanship Warranty on Every Brooklyn Project

How Much Does a Gut Renovation Cost in Brooklyn?
A full Brooklyn gut renovation typically runs $200-$350 per square foot, or roughly $80,000-$180,000 for a studio or one-bedroom and $150,000-$400,000+ for a multi-bedroom unit. Brownstone renovations that combine floors into a duplex layout tend to land at the higher end due to structural work. We confirm your exact number with a free written, itemized estimate after seeing the property.
Serving Brooklyn Renovation Projects
We work throughout Brooklyn, including Park Slope (11215), Brooklyn Heights (11201), Williamsburg (11249), Bay Ridge (11220), and Crown Heights, with crews familiar with the parking and street-access permitting most Brooklyn blocks require for dumpster placement.
Park Slope and Brooklyn Heights both sit inside designated historic districts near Prospect Park, which adds a Landmarks Preservation Commission review step for exterior work. Brooklyn is also our anchor borough for specialty services like flooring, painting, and carpentry, so we can often bundle a full renovation with finish work under one schedule.
Questions to Ask Before Hiring a Brooklyn General Contractor
- Have you worked on brownstones or limestones before? Party walls, older joist spacing, and parlor-floor layouts trip up contractors used to standard new-construction framing.
- Do you handle Landmarks Preservation Commission submissions? If your building sits in a historic district, this is a separate review process from a standard DOB permit.
- Who coordinates structural engineering for a floor-combining project? Confirm whether that's handled in-house or you're expected to hire an engineer separately.
- How is debris removal handled without a freight elevator? Ask about dumpster placement and DOT street-access permits before demo starts.
- What's covered under warranty, and for how long? Confirm the workmanship warranty term in writing before signing.
- Can you provide references from other Brooklyn brownstone or limestone projects? A contractor with real local references can speak to specifics like party wall coordination and DOT permitting that a citywide portfolio alone won't show.
Frequently Asked Questions - Brooklyn General Contracting
Do you renovate Brooklyn brownstones and limestones?
Yes. Brownstone and limestone renovations often involve older joist spacing, parlor-floor layouts, and shared party walls with neighboring buildings, all of which affect how we sequence demo and structural work. We assess these details during the initial walkthrough, sometimes with a structural engineer if the scope touches load-bearing elements, before writing your quote.
Can you combine floors or add a duplex layout in a Brooklyn townhouse?
Combining floors into a duplex or triplex typically requires structural work for a new stair opening, an engineer's stamped plan, and DOB permits filed together. We coordinate the structural engineering, permit filing, and construction as one project so the layout change is planned correctly from the start rather than discovered mid-renovation.
How do you handle debris removal for a Brooklyn brownstone gut job?
Brownstones don't have freight elevators or loading docks, so debris comes out through the front or a rear yard access point. We schedule dumpster placement and debris removal around your block's parking and DOT permit requirements before demo begins, so a truck isn't showing up to a street with no legal place to put it.
Does a Park Slope or Brooklyn Heights renovation need Landmarks approval?
If your brownstone is in the Park Slope or Brooklyn Heights Historic District, exterior work and anything visible from the street needs Landmarks Preservation Commission review before DOB will issue a permit. Interior-only work usually doesn't, but we confirm your building's designation during the walkthrough so there are no surprises once demo is scheduled.
