More Streamlined Than Traditional General Contractors

While searching ‘general contractors in Brooklyn’ may be the first route that comes to mind when renovating in NYC, this age-old path to your dream home is not always the straightest. Hiring a traditional design-bid-build general contractor usually requires additional design support you must source and manage yourself, plus complicated permit and approval work most homeowners are unfamiliar with. Read more via Design-Build Vs General Contractor: What’s The Difference?

More Control And Lower Cost Than Independent Architects

On the opposite end of the spectrum is an independent architect. Hiring an independent architect may result in more work for the client as this route can also become a burdensome partnership (think having to manage multiple parties between architect, contractors, etc). Furthermore, many clients report having little input when describing past experiences with independent architects in prior renovations. For example, common feedback from clients on prior experiences with independent architects is that it felt as if the architect acted in their own interests, resulting in clients paying exorbitant material costs for interior design that may not even suit their style. Plus, since independent architects outsource the construction, you’re often not seeing the full scope of costs until after designs are completed - which could take over six months in some circumstances.

Design Build, The Ideal Medium For Your Brooklyn Renovation

Working with a design-build renovation contractor in Brooklyn is the closest clients get to their initial expectations when renovating in NYC. From the rapport and custom-first approach to the cost and timeline, design-build renovations are specifically meant to manage expectations by delivering a system that delivers them up front and executes every time. Benefits of design-build include: 

  • Streamlined Communication: Multiple relationships become one with design-build, making Brooklyn renovations instantly easier for busy clients - who can now manage updates with one person instead of multiple.
  • Welcomed Design Input: This two-way relationship also means clients can have as much or little design input as they prefer, building directly from their mood boards or partnering with their dedicated interior designer for a reinvigorated look fit for their BK surroundings.
  • Faster Project Completion: Not only are there less middle-men for clients to deal with in design-build renovations, all needed components being under one roof means every party is working in tandem towards the same goal from day one. This leads to proactive solutions earlier in the process, faster permitting and approvals, quicker response times between parties in pivotal points of the renovation, and ultimately a shorter delivery time for clients. After all, in NYC, there’s no time to waste.

  • Improved Risk Management: The design-build umbrella of services not only expedites the move-in date, but having all needed services working in tandem early on in the process results in proactive problem solving and less change orders mid-way through the renovation.
  • Early Knowledge Of Costs: With all resources accounted for upfront, providing all-inclusive pricing for your full renovation is one of the most convenient benefits of design-build. This is especially beneficial considering most other methods of renovating in Brooklyn operate with staggered pricing, which can quickly become difficult to manage as the project proceeds.

The First Design Decision How Will Your Brownstone Live? Before a single wall moves, every Brooklyn brownstone renovation answers one question: how much of the house do you occupy, and does any of it earn income? Gallery has built all three configurations, including the single-family-to-owner's-triplex conversion at our Bed-Stuy project.
Single-Family The whole house is yours
The Living Arrangement Four floors of connected living: entertaining on the parlor level, bedrooms above, and family or guest space on the garden floor.
The Tradeoff Maximum space and privacy with no rental income offsetting carrying costs, a configuration that commands a premium at resale.
What The Renovation Involves If the house is currently multi-unit, consolidating means removing kitchens, opening the stair between floors, and filing for a new certificate of occupancy reflecting the reduced unit count.
Owner's Triplex Plus Rental Three floors yours, one earns
The Living Arrangement The owner occupies the parlor and upper floors as one connected home, while the garden level operates as a separate rental with its own entrance.
The Tradeoff Near-single-family living with income that meaningfully offsets the mortgage, at the cost of one floor and a landlord relationship.
What The Renovation Involves Fire-rated separation between the units, independent egress, a self-contained kitchen and bath for the rental, and DOB filings aligning the certificate of occupancy with the new layout, as executed at our Bed-Stuy brownstone.
Owner's Duplex Plus Rentals Two floors yours, two earn
The Living Arrangement A parlor-and-garden duplex for the owner, frequently opening to the yard, with the upper floors as one or two rental units.
The Tradeoff The strongest income position and the most manageable purchase economics, in exchange for the most compact owner footprint.
What The Renovation Involves Separate systems and metering where practical, sound isolation between owner and tenant floors, and unit layouts designed so the rentals lease well without compromising the duplex.
Unit-count changes require DOB filings and an updated certificate of occupancy, and rental configurations carry code requirements for separation and egress that vary by house. Gallery confirms the legal and structural path for your specific property during planning, alongside the financial conversation with your own advisors.

Our Brooklyn Renovation Process: What To Expect

The full process for renovating in NYC can be intricate, but don’t let that deter you from manifesting your dream home. By partnering with a full-service design-build general contractor in Brooklyn that manages every detail from start to finish, you can significantly reduce your personal workload while ensuring your design goals are met. Learn more about our entire renovation process below:

Before You Close What A Pre-Purchase Renovation Assessment Checks The most expensive renovation surprises are the ones baked into the purchase. Gallery's pre-purchase renovation assessment evaluates a Brooklyn property against your renovation goals before you commit, so the offer price reflects what the project will actually take.
Structure & Envelope
What Gets EvaluatedFoundation and party wall condition, joist and framing health, roof age, and facade condition, including the state of any brownstone cladding.
Why It Changes The DealStructural repair and facade restoration are the budget items buyers most often miss, and they compete directly with the renovation you actually want.
Mechanical, Electrical & Plumbing
What Gets EvaluatedAge and capacity of the boiler, electrical service, risers, and waste lines, plus signals of cloth wiring, galvanized pipe, or systems at end of life.
Why It Changes The DealFull systems replacement can rival the cost of the visible renovation. Knowing which systems survive determines whether the project is cosmetic or a true gut.
Layout Feasibility
What Gets EvaluatedWhether your intended plan works: kitchen and bath relocations against riser positions, bearing wall locations, ceiling heights, and stair placement.
Why It Changes The DealA property that cannot deliver your layout is the wrong property at any price. Feasibility confirmed before closing prevents buying a compromise.
Expansion Capacity
What Gets EvaluatedAvailable zoning floor area, rear yard and lot coverage rules, and the structural realities of extending back, digging down, or adding up.
Why It Changes The DealTwo identical houses can differ enormously in what they can become. Expansion capacity is value the listing rarely prices correctly, in either direction.
Regulatory Position
What Gets EvaluatedLandmark or historic district status, open DOB violations or permits, certificate of occupancy versus actual use, and, for co-ops and condos, the building's alteration rules.
Why It Changes The DealInherited violations and CofO mismatches become the buyer's problem at closing, and LPC or board oversight reshapes both the timeline and the possible scope.
Scope-To-Budget Fit
What Gets EvaluatedYour renovation goals priced against the property's actual condition, producing a realistic all-in number for purchase plus renovation.
Why It Changes The DealThe assessment converts a listing into a total-cost decision, giving you negotiating leverage on price and the confidence to walk away when the math fails.
The assessment informs your purchase decision alongside your attorney, inspector, and financial advisors rather than replacing them. When the deal closes, the findings flow directly into concept design, so the renovation starts with the diligence already done.

Our Process: Planning & SOW

Renovating an apartment in NYC requires a strategic approach from the beginning, achieved by understanding the client's unique vision and financial parameters. This foundational understanding sets the stage for a comprehensive collaboration, where we work closely with clients to explore the practical possibilities of their renovation project, aiming for a mutually beneficial partnership.

  • Phase 1 - Intro Phone Call: Before signing any contracts, our team will discuss your renovation goals and budget for your NYC apartment.
  • Phase 2 - Site Meeting: Following the initial consultation, we visit the site to evaluate the potential project with you.
  • Phase 3 - Concept Design And Project Budget: If the project is feasible, our design team and architect will provide an initial concept design, which will guide the projected budget and timeline in our formal proposal.

If the design strategy and proposal are approved, we proceed with the pre-construction and interior design process.

Townhouse Renovation New York City

Our Process: Pre-Construction & Formal Design

Before any work begins, our project managers survey the site and develop timelines for your NYC apartment renovation according to your goals, while all structural changes are reviewed by the architect and incorporated into an updated blueprint.

As the plans are developed and awaiting approval, our designers work with you to bring your design vision to life, coordinating material selections with our procurement team.

  • Phase 1 - Inspections, Diagnostic Testing & Risk Management: Even though many potential issues can be identified during initial walkthroughs, a more thorough inspection phase is necessary to ensure all internal elements are ready for renovation. This includes probing walls and consulting with specialized contractors.
  • H4: Phase 2 - Formal Design & Material Procurement: The most hands-on aspect of any interior renovation is finding the right materials for the chosen design style. That entails paint color, accent walls, flooring style, mouldings, fixtures, countertops, and more. As a full-service design-build firm in NYC, we take on the design, sourcing, and procurement of every permanent fixture needed for your full home renovation.

That overarching expertise also allows us to accommodate every architectural and interior design adjustment required, whether that’s tearing down a wall to open up your footprint or extending the back of your townhome for more square footage. We handle all architectural planning plus filings on your behalf via our award winning in-house design team and architects.

Once we have identified all site conditions, we finalize all details of the floor plan and present material selection options to choose from. This phase typically includes:

  • Design meetings at our design studio and outside showrooms
  • Receiving and inspection of all ordered finishes and fixtures
  • Procurement of all selected finishes and fixtures
  • Review of 2D and 3D lifelike renderings, plus review and approval of all material options and design plans. The kitchen render below is from our full gut renovation of a downtown Brooklyn co-op. The following image is the completed kitchen.

    Learn more about how our lifelike design renderings help clients visualize the proposed interior design plan for their Brooklyn apartment renovation.
  • Phase 3 - Building Submission: We must formally submit plans to ensure compliance with building codes and energy codes.
  • Phase 4 - DOB Submission, Approval & Permits: Renovations in NYC often require complicated approvals and permits. For co-op renovations, obtaining a tentative tax lot number from the Department of Finance is also necessary.
  • Phase 5 - Production Calendar & Logistics: Once all plans are approved and designs finalized, we establish the production calendar and begin the renovation process.

Understanding The Number The Six Levers That Move A Gut Renovation Budget Two Brooklyn gut renovations of identical square footage can land far apart in cost. The difference lives in six levers, and knowing where each sits for your property is what makes an all-inclusive proposal possible before contracts are signed.
Building Condition
What Pushes It UpStructural settlement, deteriorated joists, water damage, and the hidden conditions common in century-old construction that surface once walls open.
How It Stays ControlledInspections and diagnostic probes before pricing, so structural findings enter the proposal as line items rather than mid-project change orders.
Systems Scope
What Pushes It UpFull replacement of electrical service, plumbing, heating, and HVAC, which a true gut of an older property usually requires.
How It Stays ControlledAn honest early assessment of which systems genuinely need replacement, and doing the full scope once while walls are open instead of twice in ten years.
Historic Restoration Scope
What Pushes It UpSkilled-trade restoration of plaster, millwork, mantels, and original floors, the craftsmanship that makes an 1899 brownstone worth owning.
How It Stays ControlledAn element-by-element restore-or-replace decision made during design with costs visible, concentrating restoration budget where it carries the room.
Exterior & Facade Work
What Pushes It UpBrownstone re-facing, roof replacement, new windows, and additions like the balcony at our Bed-Stuy project, plus LPC standards where districts apply.
How It Stays ControlledScoping exterior work with the interior gut so scaffolding, permits, and trades mobilize once, rather than as a separate future project.
Added Square Footage
What Pushes It UpRear extensions, cellar conversions, and unit reconfigurations, each bringing structural engineering and expanded filings beyond the base gut.
How It Stays ControlledFeasibility and zoning confirmed during planning, so expansion enters the budget as a deliberate choice with its return understood, never as scope creep.
Finish & Millwork Tier
What Pushes It UpStone selection, custom cabinetry, appliance package, and the density of built-in millwork, the most elastic lever of the six.
How It Stays ControlledBudgetary guidance during selections, prioritizing spend where it is felt daily and finding the middle ground between an AD-ready look and the number you set.
Every lever is priced within the all-inclusive proposal before contracts are signed, which is why the diagnostic and design phases precede the final number. For a deeper breakdown, see our guide to what goes into the cost of a complete gut renovation in NYC.

Belltel Loft Renovation In Brooklyn | 365 Bridge St

The renovation provided a clean, cohesive look with bursts of contrast throughout. View the full Brooklyn loft renovation before and after.
