Home Addition Construction in New York City

When you love your neighborhood but need more space, a home addition is the answer. Zorlu Construction builds home additions throughout New York City — second-floor additions, rear extensions, dormer additions, and garage conversions — creating the additional space you need without the cost and disruption of moving.

Types of Home Additions We Build

Second Floor Additions

Many single-story Queens, Brooklyn, and Staten Island homes have the structural capacity to support a second floor addition. We evaluate foundations, existing structure, and zoning requirements to determine feasibility and design the most cost-effective second-floor addition for your property.

Rear Extensions

Extending the rear of your home adds square footage to your primary living spaces. We design and build rear additions that integrate seamlessly with your existing home, matching exterior materials and interior finishes.

Dormer Additions

Converting unused attic space into livable space through dormer additions is a popular project for New York City homeowners. Dormers add headroom, natural light, and bedrooms or flex spaces to homes with existing attics.

Garage Conversions

Converting an attached or detached garage into living space can add valuable square footage. We handle all structural, insulation, electrical, and finish work to transform garage space into comfortable living areas.

NYC Zoning and Building Department

Home additions in New York City must navigate zoning regulations including lot coverage, setback requirements, floor area ratio (FAR), and height limits that vary by neighborhood and zoning district. Our team works with architects and expeditors to design additions that are approvable and maximize what your property's zoning allows.
