Remodeling

Major structural reconfiguration: combining units, full system replacement, complete spatial reimagining. Licensed professional coordination throughout.

Remodeling is the Build service for a complete structural reconception — a project where the existing layout is not the constraint but the starting point. Walls move. Units combine. Every system is replaced from the infrastructure up. When the work is complete, the residence is fundamentally different from what it was.

Tier Options

Build

Structural reconfiguration, full system replacement, and complete spatial reconception. The studio leads design and coordinates the licensed team throughout.

Investment Range: Starting at 20% of the property value

Project Duration: 12 - 36 months

Scope: Comprehensive home transformation with structural modifications

 

Perfect for:

  • Properties requiring total transformation with space configuration
  • Homes needing comprehensive structural improvements and updates
  • Investment properties requiring complete market repositioning

Renovation

Room-level structural reconfiguration. Full design and build oversight. Licensed professional coordination when required.

Gut kitchen renovation, full bathroom renovation, non-structural wall reconfiguration, complete electrical upgrade, full smart home integration, and co-op board submission managed by the studio. Construction documentation, bidding, contractor selection, and construction administration are all within scope.

Notes

Combining apartment units in a co-op building adds 12–20 weeks for board approval of the combination plan. LPC review in landmark buildings can add an additional 8–16 weeks.

Licensed Professional CoordinationWhen projects require architectural drawings, structural engineering, permit procurement, or Building Department liaison, NYC Interior Design collaborates with New York State licensed architects, engineers, and registered professionals. We coordinate this process on the client's behalf as part of the service.

In Detail

A Remodeling project requires a licensed general contractor, a structural engineer of record, and an architect of record for all permit drawings submitted to the NYC Department of Buildings. The studio engages and coordinates all three. The client has one point of accountability for the design outcome. The licensed professionals execute. We lead every design decision from schematic through occupancy.

What's Included

Overview: Everything in Home Renovation plus: combining multiple apartment units, complete electrical and plumbing system replacement as a primary scope item, major structural alterations, full HVAC system design where permitted. The most complex residential work we undertake.

Scope Details:

  • When projects require architectural drawings, structural engineering, permit procurement, or Building Department liaison, we collaborate with New York State licensed architects, engineers, and registered professionals. We coordinate this process on the client's behalf as part of the service.
  • Everything in Home Renovation
  • Combining multiple apartment units: structural opening of party walls, new egress planning, unified MEP systems
  • Complete electrical system replacement: new panel, new wiring throughout
  • Complete plumbing system replacement: new supply and drain throughout
  • HVAC system design and installation (where building permits)
  • Major structural alterations: load-bearing wall removal or relocation (structural engineer of record (NYS licensed) required)
  • LPC coordination for landmark buildings
  • Permit coordination with NYC Department of Buildings
  • Coordination with architect of record (NYS licensed — required for structural and MEP permit filings)
  • Full smart home infrastructure as a primary scope item
  • Complete millwork program throughout combined space

The Process

Process Methodology

  • Combination Complexity: Combining two or more apartments is the most complex residential renovation we undertake. Every party wall that is opened requires structural engineering. Every MEP system that is unified requires coordination between the original systems of both units. The board approval process for a combination is significantly more demanding than a standard alteration — we have managed this process multiple times and approach it systematically.
  • Systems Sequencing: In a full remodel, the sequencing of MEP work determines the project timeline. Electrical, plumbing, and HVAC rough-in must happen in the correct order, and delays in any one system delay the finish work that follows. Construction management at this level is a professional discipline.
  • Smart Home At Remodel: When all walls are open, smart home infrastructure can be designed without compromise. This is the only moment when the full potential of a smart home can be realized — every conduit run is optimal, every outlet is exactly where it should be, every system is integrated at the infrastructure level.
  • Licensed Professional Coordination: Any project that touches load-bearing structure, requires permit filing, or involves Building Department coordination requires a New York State licensed architect and/or structural engineer. We engage and coordinate these professionals as part of the service — we do not substitute for them. The architect of record files permits; we manage the full coordination between the design intent and the licensed professional's drawings.

Process by Subservice

Build

20%+ of property value12–24+ months

Renovation

Starting at 20% of property value12–18 months
Pre-Renovation Audit1–2 weeks

Structural assessment. MEP system review. Board requirements mapped. Alteration agreement template reviewed. Budget framework established.

Schematic Design3–4 weeks

Floor plan options developed with board approval in mind. Layout alternatives presented. Scope confirmed. Structural engineer engaged for any bearing wall work.

Design Development6–8 weeks

Full material specification, millwork design, lighting program, smart home scope. Construction documents prepared.

Board Submission6–12 weeks

Complete board submission prepared and submitted. We manage this process — the client's time commitment is signing documents, not preparing them.

Construction16–24 weeks

Construction with weekly site visits and full trade coordination. Smart home rough-in before walls close. Punch list at practical completion.

Completion and Handover2–3 weeks

Completion certificate process managed. Systems commissioning. Client training. Final punch list resolved.

Ideal For

The Client

A client who has acquired two adjacent apartments and wants to combine them into a single residence. Or a client in a townhouse undertaking a complete whole-building renovation. Or a client in a new acquisition that requires full system replacement and structural reconfiguration to match their program.

Active Neighborhoods: Lenox Hill/Park Avenue, Upper East Side, Upper West Side, Tribeca, West Village, Financial District, SoHo, Chelsea

Not A Fit If

If the project does not involve structural alterations, system replacement, or unit combination, Home Renovation is the appropriate scope at lower cost and shorter timeline.

Tier Evolution

Home Remodeling is the highest-scope service we offer. The natural progression after completion is Bespoke Decoration — the build quality of a remodeled space warrants a decoration program at the same level.

Building Requirements

Applicable Architecture

Pre-war co-op unit combinations are the most common Home Remodeling scenario in our practice. Glass tower condominiums: simpler combination approval process. Townhouses: whole-building remodel is distinct from apartment combination — floor-by-floor structural work with different engineering requirements.
