Park Slope is defined by its brownstones and limestone townhouses — narrow, deep, four-story buildings with original parlor floors, ornamental detail, and layouts that were never designed around a modern kitchen or a family bathroom on every floor. Renovating one well means understanding how these houses were built, not just what a homeowner wants to change.

Park Slope Historic District (landmarked)
WhiteStar General Contractors has spent over 20 years working inside Brooklyn’s brownstone housing stock, and Park Slope is one of the neighborhoods where that experience shows most directly. We specialize in Brownstone Renovation — reconfiguring original floor plans, updating aging mechanical systems, and restoring or replacing historic details, all while respecting the structural realities of a 100+ year-old townhouse.
What Makes a Park Slope Renovation Different
Brownstone-specific structural knowledge
Original joists, load-bearing party walls, and narrow lot widths mean layout changes need to be planned around the building’s bones, not just its finishes. A wall that looks non-structural on the parlor floor may be carrying load from the floor above.
Bathroom and kitchen reconfiguration in historic homes
Many Park Slope brownstones were built with a single bathroom per floor and kitchens tucked into the rear extension. Modernizing plumbing lines and adding bathrooms on upper floors is one of our most requested services here, and it usually means running new stacks through existing chases without disturbing original finishes elsewhere.
Parlor floor restoration
Original moldings, pocket doors, marble mantels, and plaster medallions are a major part of a brownstone’s value. We restore and integrate these details into a modern layout rather than removing them — this is often what separates a renovation that adds value from one that erases it.
Rear extension and garden-level work
Many Park Slope brownstones have rear extensions added over decades, often with inconsistent foundations and roof lines. These areas frequently need structural evaluation before a kitchen or family room expansion can move forward.
Landmark district rules
Much of Park Slope sits within a designated historic district, which affects what can be changed on the facade and street-facing elevations, including stoops, window frames, and cornices. We factor this into project planning from the first estimate, not after a permit gets rejected.

Frequently Asked Questions
Do you specialize in brownstone renovations specifically, or general remodeling?
Both, but brownstone and townhouse renovation is one of our core specialties in Brooklyn, and Park Slope’s building stock is exactly the type of project we handle most often.
Can you add a bathroom to an existing floor in a Park Slope brownstone?
Yes. This is a common request. We evaluate the existing plumbing stack and structural layout to find the most cost-effective way to add or relocate bathrooms without opening walls unnecessarily.
Will you handle Landmarks Preservation Commission (LPC) requirements if my house is in a historic district?
Can you renovate the rear extension separately from the main house?
Yes, this is a common phased approach — many homeowners renovate the rear extension and kitchen first, then handle upper floors in a later phase.
How disruptive is a brownstone renovation if I want to stay in the house?
Depending on scope, partial renovations (single floor, kitchen, or bathroom) can often be done while the rest of the house remains livable, though full gut renovations typically require the home to be vacant.
Do you serve other brownstone neighborhoods near Park Slope?
Yes, including Brooklyn Heights, which shares a similar building stock and landmark rules.
