Frequently asked questions
Renovating in New York City is uniquely complex. Co-op and condo board approvals, Department of Buildings requirements, pre-war building constraints, and tight logistical realities shape every project. These answers are designed to help homeowners set accurate expectations and make more informed decisions before renovation begins.
Process FAQs
Yes. We handle the entire process start to finish, from architectural services, permits, and board approval to interior design, material procurement, project management and construction.
As an all-inclusive design-build firm in New York City, our interior design and architectural services are a value add within all of our end-to-end renovations.
Yes. We are an interior renovation contractor with a full-service design-build approach. We renovate every aspect of interior work in all types of residential renovations in New York, from condos/co-ops and lofts to brownstones and townhomes. We’re experts in renovating pre-war homes, kitchens, bathrooms, bedrooms, dining areas, flooring, sourcing custom pieces, building entirely new rooms (or even balconies), millwork, and all that falls in between.
People often unwittingly work with a separate designer and architect, or a separate designer and architect and builder. With a design-build firm that has built-in architectural services, multiple relationships become one, ensuring architectural plans and expectations are never muddled in translation from one contractor to the next. Essentially, a design-build firm performs all the functions of an architecture firm, along with all additional aspects of an interior designer, contractor, and construction manager.

At their core, the main difference between design-build vs design-bid-build is that the design-build offers a full-service, all-inclusive renovation package for homeowners who value a partner with one main point of contact to oversee the entire process, whereas design-bid-build delivers a more piecemeal approach that allows for more flexibility. For more detail, read our full breakdown on the two approaches to NYC contractors here.
It varies by firm. Some restrict selections to specific brands or in-house showrooms, which can limit options and inflate costs. Others are fully vendor-agnostic, giving clients open access to the broader market. At Gallery KBNY, we are brand and vendor neutral, and trade discounts are passed through to clients without markup.
Understand The Process: Our Material Selection & Procurement Services
Yes. We are fully licensed with the New York City Department of Consumer Affairs and the New York City Department of Buildings. We also carry lead-safe and Occupational Safety and Health Administration certifications, as well as all other necessary certifications. Finally, we carry insurance that’s significantly higher than the required limits ($5 million in general liability, $1 million in workers’ compensation, and $3 million in auto).
A full-service design-build approach is generally the most effective method. NYC renovations require close coordination across design, permitting, and construction. When those functions are managed by separate parties, misalignment, delays, and budget uncertainty are common. An integrated team evaluates design decisions against structural conditions, building limitations, and code requirements in real time, before problems become costly.

Co-op and condo renovations require formal board approval before construction begins, including submission packages with architectural and engineering drawings, insurance documentation, and indemnification agreements. Construction teams must also comply with building-specific rules governing work hours, noise, elevator use, and material deliveries. Working with a firm fluent in board requirements and building protocols is essential, it directly affects how efficiently approvals are obtained and how smoothly construction proceeds.

NYC renovations generally follow a structured multi-phase process: initial consultation and feasibility, design development and construction documentation, board submission and approval (for co-ops and condos), permitting, construction, and final inspections and closeout. Each phase has building-specific and regulatory requirements that must be met before the next can begin.

In a well-run renovation, communication is structured and centralized. At Gallery KBNY, clients have a dedicated project manager and project coordinator as primary contacts, along with direct involvement from a firm partner throughout the project. A secure project management platform centralizes schedules, selections, change orders, invoices, progress photos, and messaging in one place, which is particularly valuable for remote clients.

With a full-service design-build firm, involvement is typically limited to high-level decisions rather than day-to-day coordination. Gallery KBNY manages design, board submissions, permits, construction, and oversight under one integrated team. Some clients prefer frequent design input; others rely on the team to present curated options. Both approaches are fully supported.

Most unforeseen conditions can be avoided through thorough pre-construction due diligence: evaluating electrical loads, testing for lead and asbestos, assessing plumbing limitations, and reviewing building-specific requirements before work begins. At Gallery KBNY, change orders attributable to unforeseen conditions average less than 2% of total project budget, and are zero on the majority of projects (excluding client-initiated changes). When a genuinely unexpected condition does arise, it is assessed immediately and presented with clear cost and schedule implications before work proceeds.

Gallery KBNY focuses exclusively on co-ops, condos, and pre-war apartments in Manhattan and Brooklyn. The firm's differentiators are rigorous pre-construction due diligence, a fully integrated design-build model, and deep experience navigating the board, DOB, and building-specific complexities that define NYC renovation. Architecture, interior design, project management, and construction operate under one coordinated team, reducing risk and keeping accountability clear from concept through completion.
Learn more about what separates us from other general contractors and so-called design-build firms.
Yes. All Gallery KBNY projects include a full set of construction and design drawings — technical drawings, elevations, reflected ceiling and electrical plans — as well as photorealistic 3D renderings so clients can visualize the finished space before work begins.
See The Specifics: Render To Reality: How Our Rendering Process Helps Clients Visualize Their NYC Renovation
Look beyond visuals and pricing. A reputable NYC renovation firm can clearly explain how it navigates board approvals, DOB filings, building rules, and structural constraints, and demonstrates this through completed projects, not just renderings. Strong firms emphasize detailed pre-construction planning, realistic timelines, itemized estimates, and transparent allowances. Disciplined change-order controls, structured communication, and consistent project oversight are also reliable indicators. In NYC, the firms most worth trusting are those that anticipate complexity and communicate clearly, not those promising the lowest price or fastest turnaround.

Cost FAQs
Change orders fall into two categories: client-initiated (scope additions, finish upgrades, layout adjustments) and contractor-initiated (additional work required to fulfill the agreed scope). Both should always be documented in writing with clear explanations of cost, schedule impact, and any applicable credits. On well-planned projects with thorough pre-construction investigation, contractor-initiated change orders should be uncommon.

Renovation costs vary based on apartment size, scope, finish level, existing conditions, and building type. As a 2026 benchmark for a full renovation in Manhattan:
- Upper mid-tier finishes: $400 to $550 per sq ft, or approximately $720,000 to $990,000 for an 1,800 sq ft apartment
- Luxury finishes, elaborate millwork, and extensive HVAC or window work: $550 to $850+ per sq ft, or approximately $990,000 to $1,530,000+ for the same apartment
- Pre-war apartments: typically $600 per sq ft and up, since older infrastructure and concealed conditions add labor and scope
- Layout changes such as relocating kitchens, bathrooms, or walls: typically $550 per sq ft and up
- Brownstones and townhouses: typically $700 per sq ft and up, and $800 per sq ft and up in landmarked buildings

Yes. Our project minimum is $400,000.
A transparent estimate is itemized, specific to your building and project, and clearly defines what is included, excluded, and how costs are allocated. In NYC, it should also account for board submissions, permitting, DOB filings, inspections, and building-specific requirements. Watch for artificially low allowances used to make pricing appear competitive — these reliably become change orders later.

Budget overruns are almost always preventable, and prevention happens before construction, not during it. The most reliable approach: define scope precisely, confirm building constraints early (electrical capacity, plumbing limitations, HVAC feasibility, work rules), and avoid vague allowances that don't reflect actual intended materials. During construction, locking key selections early, tracking long-lead items, and enforcing strict change-order controls keep budgets from quietly drifting.

timeline FAQs
For a full apartment of about 1,700 square feet, construction typically runs five to six months. Design, board approval, and permitting come first and usually take four to six months, so most full renovations move from first consultation to move-in in 10 to 12 months. Scope, building rules, and how much infrastructure is being replaced set where a project falls in that range.

The construction portion of a full kitchen renovation typically takes 7 to 11 weeks. Door to door, the timeline depends mostly on the building: about 10 to 14 weeks in a private townhouse, 14 to 20 weeks in a condo, 16 to 24 weeks in a post-war co-op, and 20 to 30 weeks in a pre-war co-op, where board and engineering review take longer. Gallery KBNY orders custom cabinetry, stone, and long-lead appliances during design and approvals, so materials arrive ready for the build.

The construction portion of a bathroom renovation typically takes three to four weeks. Gallery KBNY renovates bathrooms as part of larger interior renovations, so bathroom work is sequenced alongside the rest of the apartment within the overall project schedule.

Board review and execution of the alteration agreement typically take 6 to 10 weeks in a post-war co-op and 8 to 14 weeks in a pre-war co-op, where asbestos filings, electrical load letters, and engineering review add steps. DOB permits usually run at the same time. A complete package with full technical drawings and specifications tends to clear the building's reviewing architect in one or two rounds, which keeps the approval phase on schedule.
Get Into The Specifics: In-Depth Co-Op Board Approval Process For Complex NYC Renovations: What to Expect
A design-build firm provides architecture, interior design, expediting, and construction under one scope and contract. A general contractor builds from drawings produced by a separate architect. In NYC co-op and condo renovations specifically, the coordination gaps that emerge between separate design and construction teams often lead to delays and cost overruns that an integrated model avoids.
Read More: Design-Build vs General Contractor: What's The Difference?
Prioritize domain expertise above almost everything else. A firm experienced with your specific building type (co-op, condo, or pre-war) will understand board requirements, alteration agreements, DOB filings, and the structural and mechanical nuances of dense urban buildings. Location-specific experience also matters: familiarity with a neighborhood's building stock and approval culture can meaningfully reduce friction. Beyond technical knowledge, look for clear communication, transparent pricing, and a track record on comparable projects.
Dig Deeper: How To Distinguish True Design-Build Expertise For NYC Apartment Renovations
It depends on project complexity and your priorities. Design-build is particularly well suited to projects where early budget certainty, constructability, and schedule control matter. Because the builder is involved during design, costs and logistics are evaluated in real time, reducing redesigns and change orders once construction begins. A traditional architect-first model can work well for simpler or more decorative scopes where cost variability is less of a concern.
Consider Further: Will An Architect Have Your Best Interests In Mind?
The most significant factors are scope of work, building approvals, and procurement timelines. Projects that relocate plumbing, install HVAC, or alter structural elements take longer than decorative renovations. In co-ops and condos, board submissions and reviews can add months before construction begins. Long-lead materials such as custom cabinetry, stone, and specialty fixtures must be ordered early. Late design decisions or scope changes during construction are among the most common causes of delays.
At minimum, begin planning 5 to 6 months before your desired construction start date. For full apartment renovations, starting up to one year before your target completion date is advisable. Board approvals, architectural documentation, and procurement typically require 4 to 6 months before construction can begin, and delays caused by underestimating this phase are among the most common in NYC renovation.
The most common causes are incomplete planning, board approval timelines, late-stage design decisions, and long-lead procurement. Building-specific rules such as work-hour restrictions, elevator scheduling, holiday blackouts, and renovation duration limits also affect productivity. In pre-war buildings, unforeseen conditions such as outdated wiring, concealed plumbing issues, or hazardous materials can pause work. Projects that invest in thorough pre-construction planning consistently move more predictably.
