Loft Renovation Services in New York City

Melani General Contractor delivers specialized loft renovation services for converted industrial spaces, live/work lofts, and commercial-to-residential conversions across all five boroughs. Loft renovation demands a different approach than standard apartment work — open floor plans, exposed structural elements, non-standard ceiling heights, concrete floors, and oversized windows create both unique design opportunities and construction challenges. Our licensed team manages every phase from design and DOB permitting through construction and final inspection. Call (718) 283-4154 to schedule your free on-site estimate.

Services

Our Loft Renovation Services

Open-plan build-outs, mezzanines, kitchens and baths on concrete, full mechanical systems, and exposed-element restoration.

Open Floor Plan Design and Build-Out

Loft spaces are defined by their open layouts, but most residents need defined living zones without sacrificing the spacious feel. We design and build partial walls, custom room dividers, glass partitions, sliding barn doors, and built-in millwork that create functional separation between living, sleeping, working, and entertaining areas while maintaining sight lines and natural light flow.

Mezzanine and Sleeping Loft Construction

High-ceiling lofts (12–16+ feet) offer the opportunity to add significant square footage through mezzanine construction. We design and build structural steel or wood-framed mezzanines for bedrooms, home offices, or storage — with proper guardrails, egress requirements, and code-compliant stairway or ladder access. DOB permits are required for permanent mezzanine installations.

Kitchen Construction in Loft Spaces

Loft kitchens often need to be built from scratch in spaces that were never designed for residential cooking. We handle all plumbing and gas rough-ins, electrical circuits for appliances, ventilation through exterior walls or long duct runs, and custom kitchen island builds that anchor the cooking zone within the open floor plan.

Bathroom Construction and Plumbing

Adding or renovating bathrooms in loft spaces frequently requires building on concrete slabs with limited drain access. We core-drill concrete for new drain lines, install raised platforms or subfloor routing when necessary, and apply proper waterproofing systems. Our licensed plumbers handle all supply and drain connections for these non-standard installations.

Electrical System Design and Installation

Converted industrial lofts may have commercial-grade electrical systems or insufficient residential wiring. Our licensed electricians design and install residential-code-compliant electrical systems including panel upgrades, properly zoned circuits, track lighting, pendant fixtures, and outlet placement optimized for open floor plan layouts.

Concrete Floor Finishing and Flooring Installation

Loft concrete floors can be polished, stained, or epoxy-coated for an industrial aesthetic, or covered with hardwood, engineered wood, or luxury vinyl for warmth. We grind and level concrete substrates, install radiant heat systems when desired, and apply appropriate underlayment for the chosen flooring material.

More on Flooring Installation

Exposed Element Treatment

Exposed brick, structural beams, ductwork, and piping are signature loft features. We clean, seal, and restore exposed brick walls, paint exposed structural steel and ductwork, and incorporate these industrial elements into the overall design rather than concealing them behind drywall.

Cost

How Much Does a Loft Renovation Cost in NYC?

Loft renovation costs in New York City depend on the starting condition of the space and scope of the build-out. Here are general ranges based on our project history.

Cosmetic Update
Painting, flooring, lighting, fixtures
$25,000–$60,000
Partial Build-Out
Kitchen, bathroom, some partitions
$75,000–$175,000
Full Build-Out or Gut Renovation
Complete residential conversion
$150–$400+ / sq ft

Loft-specific cost factors

  • Concrete core-drilling and slab work for plumbing adds cost over standard framed-floor construction
  • Mezzanine construction requires structural engineering and DOB permits
  • Long mechanical runs (plumbing, HVAC, ventilation) across open floor plans increase material and labor costs
  • Building-specific requirements in co-op and condo loft buildings add board approval timelines and administrative costs
  • Sound attenuation between loft units often requires specialized acoustic treatment

We provide itemized estimates that separate structural, mechanical, and finish costs so you know exactly where your budget goes — including plumbing routed through concrete and any board requirements your loft building imposes.

Building Types

Loft Renovation by Building Type

Raw industrial conversions, managed loft buildings, and mixed-use live/work spaces each carry their own approvals and code path.

Former Industrial / Warehouse Loft Conversion

Converting raw commercial space to residential use involves full mechanical system installation, building code compliance for residential occupancy, and creating livable spaces within industrial shells. We handle certificate of occupancy requirements, DOB filings, and the complete build-out from rough-in through finishes.

Gut Renovation

Co-op and Condo Loft Renovation

Lofts in managed buildings require board approval before renovation begins. We prepare alteration agreement packages, coordinate with building management on construction logistics, and comply with all building-mandated protocols during the renovation process.

Co-op & Condo Renovation

Live/Work Loft Renovation

Live/work spaces require zoning that accommodates both residential and commercial use. We design renovations that satisfy mixed-use requirements while creating comfortable living environments with dedicated workspace areas, proper soundproofing, and separate utility metering when required.

Process

Our Loft Renovation Process

Five steps, in order — consultation through final inspection and walkthrough.

    We prepare a detailed scope of work with itemized costs. For complex build-outs, we coordinate with architects and structural engineers for drawings and calculations.

  3. 3

    Permits and Approvals

    We file DOB applications, prepare co-op/condo board submissions when applicable, and obtain all required permits before construction.

  4. 4

    Construction

    Our crews handle concrete work, framing, mechanical rough-in, mezzanine construction, and all finish work — flooring, cabinetry, tile, millwork, painting, and fixture installation.

  5. 5
