Floor Plan, Interiors and 3D Visualization

Design That Makes Better Use of Your Apartment

Better storage, bedroom privacy, and a more functional kitchen begin with the floor plan.

We study daylight, room proportions, and circulation, examining the way you move between spaces, developing layout options suited to your priorities. Existing-condition surveys and available building records inform those studies with 3D visualizations to help you compare proposed materials and spatial relationships.

Our kitchen and bathroom design is developed alongside cabinetry, lighting, and finishes. The scope may retain existing interiors or involve a gut renovation to reorganize rooms and update systems.

Solved Before Construction Begins

Common Co-op Renovation Issues

Your Architect identifies building constraints and develops solutions before construction begins.

A Wall You Want to Remove Contains Shared Services

ProblemWalls may contain structural elements, plumbing, or ventilation serving other apartments.

Our approachOur floor plan feasibility studies assess the proposed changes and identify where probes or engineering input are needed.

Example: At 200 West 20th Street, Chelsea, our co-op kitchen renovation scope included wall removal to create an open layout.

The Proposed Kitchen or Bathroom Location Is Restricted

ProblemExisting drainage and building rules may prevent relocation, including wet areas above dry rooms below.

Our approachThrough co-op board approval assistance, we review the alteration requirements and coordinate feasible layout options.

New Floors or Bathrooms Need More Than Finish Selections

ProblemFlooring and bathroom assemblies may need to meet specific sound-control and waterproofing requirements.

Our approachOur architectural design services incorporate the required assemblies into construction drawings before materials are ordered.

Co-op Board and NYC Approvals

Building consent and government permits are separate approval processes. Our board approval assistance addresses the alteration submission, technical review comments, and supporting documents.

We assess the scope against DOB permit requirements. Some minor work is exempt from a DOB permit but may still require your building’s review.

For landmark properties and buildings in historic districts, LPC approval must be obtained, even on projects focusing on interior work only, which requires LPC approval.

Design, Filing and Oversight Under One Roof

Why Choose Apartment Renovation NYC?

Our architectural team brings design, in-house filing coordination, and construction oversight together, serving as your professional advisor and owner’s representative throughout the renovation.

Licensed Architectural Practice

Principal Architect Lenka Ilic, NYS Registered Architect, coordinates and makes final decisions ensuring every project meets our standard for renovations. She also serves as Technical Director of our NYC DOB registered Special Inspection Agency. We provide applicable inspections within our registered scope and coordinate completion documentation and required sign-offs.

In-House DOB Filing

Our team prepares your drawings and handles DOB filing and expediting. Design revisions and application information stays coordinated without any third party filing intermediary.

Owner's Representation

We define the work before contractor bidding, following the design and documentation sequence described by the AIA. Before you sign a construction agreement, we establish construction administration procedures for professional review of the contractor’s submissions, charges, and progress.

During construction, we review submittals, respond to contractor questions, evaluate change orders and payment applications, and visit the site periodically. These services keep you informed when technical decisions or additional costs arise.

Often third-party elsewhere. In-house with us.

Fees, Construction and Third-Party Costs

How Much Does a Co-op Renovation Cost in NYC?

Architectural services establish the drawings and specifications needed for contractor pricing. Without them, construction estimates remain rough figures based on assumptions.

Architectural and Professional Fees

Our proposal identifies fees for architectural and interior design, filing coordination, inspections, and construction administration, as applicable. Fees reflect the scope and complexity of your renovation.

Construction Costs

Our cost guide provides preliminary references of $350-$450+ per square foot for renovations involving kitchens and bathrooms, and $450-$550+ per square foot for full gut renovations. Existing conditions, the area renovated, and material selections affect pricing. Contractors prepare project-specific bids from the coordinated construction documents, which we review before you sign a construction agreement.

Third-Party Costs

Engineering, environmental testing, DOB agency fees, and building review charges are budgeted separately. Our office coordinates required consultants, including engineering when needed, and testing.

Planning, Approvals and Construction

How Long Does a Co-op Renovation Take in NYC?

The timeline includes architectural planning, approvals, and construction, with some activities overlapping. Our renovation timeline provides planning estimates that vary with scope and building requirements.

Architectural Planning and Design

Allow 1-3 weeks for programming and floor plan feasibility, followed by 2-8 weeks for design development including interior and architectural design. Construction drawings and consultant coordination may require additional time, depending on complexity.

Filings and Approvals

Allow 2-4 weeks for co-op board review and 2-4 weeks for DOB permitting, with additional review rounds extending this stage. Contractor selection generally requires 2-4 weeks and may overlap with approvals.

Construction

Smaller renovations generally fall toward the shorter end, while full gut renovations take longer. Through construction administration, we oversee construction phase and inform you of progress. If any concealed conditions need to be addressed we coordinate with the contractor. During construction phase we perform required inspections to meet project milestones.

Co-op Renovation FAQs

Answers to common questions about renovating a co-op, with links to our services and practical guides.

Do I need an Architect for a co-op renovation?

Layout and building-system changes commonly require professional design and documentation.

Do I need board approval for a kitchen or bathroom remodel?

Many co-ops require it, even without relocating fixtures. We’ll check the building’s alteration requirements before starting.

Can I remove walls in a co-op apartment?

Possibly. Your Architect shall assess structural conditions, concealed services, and building restrictions first.

Can I move a kitchen or bathroom in a co-op?

It depends on plumbing, ventilation, structure, code, and the building’s wet-area restrictions.

How much should I budget for a co-op renovation?

Budget for architectural services, construction, and third-party fees, see our renovation cost guide for more information. Construction drawings establish the scope for contractor pricing.

How long does co-op renovation approval take?

Timing varies by building and submission. Allow for review comments and revisions before scheduling construction. See our renovation timeline and steps guide to see the intricacies.

Can I live in my apartment during renovation?

Possibly, if safe access and essential facilities remain available. Extensive renovations often require temporary accommodation.

Should I hire a contractor before an Architect?

Engage your Architect first so contractors can price a defined design and scope.

Can a co-op renovation include combining apartments?

Most likely however, combining apartments require a feasibility review, building consent, and applicable filings.
