How to Renovate in Brooklyn

Renovating a home in Brooklyn isn’t just about fresh finishes or chasing trends—it’s about creating a space that actually works for the way you live. Maybe your brownstone’s layout has never quite made sense, or your prewar apartment needs a little more function to match its charm. Whatever the case, the goal isn’t to make it perfect. It’s to make it yours.

Brooklyn homes come with a lot of character—and a lot of quirks. So it makes sense that renovating one can feel like a big undertaking. There are permits, boards, building rules, and more than a few moments where you’ll wonder if it’s all worth it. (It is.) That’s where we come in.

At Block, we know this is more than a home improvement project. It’s personal. And we’re here to help you move forward with real guidance, a clear plan, and support you can count on. We help you see what’s possible, figure out what matters most, and stay grounded in the decisions that will get you there, without second-guessing.

Because in Brooklyn, a great home isn’t just well-designed. It’s well-lived in. And the best renovations are the ones that make everyday life feel a little more like you.

Renovating your home in Brooklyn

Renovating in Brooklyn isn’t just a design project—it’s a personal one. You're not starting from scratch. You're working with a space that already has history, quirks, charm, and maybe a few things that drive you up the wall. And the goal isn't to erase that—it’s to make the space work for your life now.

Let’s talk brownstones. They’re beautiful, no doubt about it. Tall ceilings, carved moldings, old fireplaces—there’s a reason people fall in love with them. But these homes weren’t built with modern plumbing or insulation or even the idea of an open floor plan. You often deal with choppy layouts, aging systems, and details you want to preserve but need to work around. Renovating a brownstone is a balancing act: keeping the soul of the place while bringing in the comfort and utility you need to live well in it today.

Townhouses are similar in spirit, but are newer and more flexible regarding layout. Many were built in the early 20th century and have been updated in bits and pieces. You’ll often find a decent shell—good bones, solid light—but a need for smarter storage, better insulation, and mechanical systems that aren’t 60 years old. If you want to renovate a bathroom, carve out a mudroom, or finally create a real office space, you can make some smart upgrades without reinventing the wheel.

Then you’ll find prewar apartments across neighborhoods like Prospect Heights, Bay Ridge, and Kensington. These units usually have high ceilings, solid walls, and just enough vintage detail to be charming. Still, they also tend to have tiny galley kitchens, no real ventilation, and bathrooms that feel more like afterthoughts. The footprint is fixed, but how you use it doesn’t have to be. A lot of what we do in these spaces is reconfigure the layout for better functionality—removing a wall here, adjusting storage there—without losing the character that gives the place its soul.

Lofts—mostly in Williamsburg, DUMBO, and parts of Bushwick—are a different animal entirely. Open space is the draw, but that blank canvas also means more decisions. Where does the bedroom go? How do you separate the kitchen from the living area without chopping things up? Where are you putting your closet? Do you even have one? Renovating a loft is about creating zones and flow, often with custom storage and smart materials that complement the rawness of the space instead of fighting it.

And finally, condos and co-ops. These are everywhere—from Carroll Gardens to Downtown Brooklyn—and they bring their own challenges. 

Renovation here isn’t just about your unit. It’s also about working with your building. That means dealing with board approvals, alteration agreements, work-hour restrictions, and building insurance requirements. The space might be straightforward. The process? Less so. But with a clear plan and the right paperwork, it’s manageable—and absolutely worth doing if you’re ready to make your home feel more like yours.

Here’s the bottom line: renovating in Brooklyn isn’t a plug-and-play process. But at Block, we’ve worked in all kinds of Brooklyn homes, and we know how to navigate the unique mix of architecture, regulation, and ambition that comes with each project. We’re here to help you move from “what if” to “this works,” with clear guidance, expert support, and a whole lot of respect for what it means to call a place home.

Navigating Brooklyn renovation challenges

If you’re renovating a home in Brooklyn, you’re working within a system—sometimes a very particular one—with its own rules, pace, and, frankly, quirks. It’s totally doable, but you need to know what you’re walking into. Permits. Boards. Landmarks. Tiny kitchens. Contractors who ghost. It’s a lot. But it’s not impossible—with the right plan, you can move through it without losing momentum (or your mind).

Landmark and historic district regulations

Let’s start with one of the biggest curveballs: if your home’s in a landmarked neighborhood—say, Park Slope, Brooklyn Heights, Fort Greene—you’ll need approval for any work that touches the exterior. We’re talking windows, front doors, facades, and even some roof work. It all has to go through the Landmarks Preservation Commission (LPC), and their job is to ensure the neighborhood's architectural character stays intact.

Now, that doesn’t mean you can’t update your home. It just means you have to do it with care and paperwork. 

Co-op and condo renovation rules

If you're in a co-op or condo, you’ll deal with a different set of building rules. Most buildings require you to submit renovation plans before you can get started. They’ll review noise, work hours, delivery logistics, and whether your project affects shared systems (plumbing risers, electrical panels, etc.). You’ll likely need to provide contractor insurance and sign an alteration agreement. It’s a lot of back and forth, and timelines can stretch if you don’t get it right the first time.

This part of the process trips up a lot of people. We help avoid that. From scope reviews to working within board requirements, we ensure your renovation is board-friendly before the first hammer swings.

NYC permitting requirements

Then there’s the city itself. Any work that involves plumbing, electrical, or structural changes? That usually requires permits from the Department of Buildings (DOB). Even seemingly small upgrades can trigger the need for sign-offs, filings, and licensed professionals. You can technically skip permits, but you’d be doing yourself—and your resale value—a disservice. It can cause major issues down the line, especially when it comes time to sell.

We work with pros who know the DOB system, how to file correctly, and how to keep your project on the right side of regulation.

Designing for tight spaces

Space is always at a premium in Brooklyn. Even larger homes usually have a few rooms that just don’t make sense for how people live today. That’s where thoughtful design comes in.

• Small bathrooms are a common pain point—narrow layouts, awkward plumbing, and not enough storage—you know the drill. With the right planning, even a tiny bath can feel spacious. We’ve helped homeowners rework layouts, add floating vanities, and rethink where every inch goes, so the room feels less like a squeeze and more like a retreat.
• Small kitchens often suffer from outdated layouts and a lack of function. It’s not just about cabinets—how you move through the space, where the appliances sit, and whether you have enough prep area to make dinner without juggling cutting boards. A good kitchen renovation can completely shift how the space works.

We’ve seen time and again how a few smart layout changes and materials that make sense for your lifestyle can turn a cramped kitchen into the true center of your home.

Finding the right contractor

This might be the biggest challenge of all: finding a contractor who’s reliable, skilled, and easy to work with. Someone who knows Brooklyn buildings, understands local codes, and doesn’t disappear mid-project

Too many homeowners go into this part blind, asking neighbors, scrolling online listings, hoping for the best. But getting it wrong can cost you. Miscommunications, drawn-out timelines, budget creep—it all adds up fast.

At Block, we take the guesswork out of contractor selection. Every contractor on our platform is thoroughly vetted for craftsmanship, professionalism, and transparency. We match you with someone based on your project type, location, and goals. 

Before, during, and after your Brooklyn renovation

A great renovation doesn’t start with demolition—it begins with a clear plan and the right people around you. And when the work’s done, it’s not just about walking into a newly finished space. It’s about knowing everything came together the way you hoped. Here’s how to feel ready before the first day of work, stay grounded while it’s underway, and tie things up confidently when done.

Before renovation

The decisions you make upfront set the tone for the entire process. Get this part right, and everything else gets a whole lot easier.

Plan your renovation

Start with Block’s free Renovation Planner. It’s an easy way to get a visual sense of your space, narrow down your style, and start playing with layouts and materials while getting a personalized cost estimate. You’ll understand your options before committing to anything.

Define your goals and style

Why are you renovating? Are you after more space, better flow, improved resale value, or all of the above? Having a clear vision early on makes every decision easier, from layout to lighting. Knowing your style helps, too. That way, the finished space doesn’t just look good—it feels like you.

Set a clear, realistic budget

Brooklyn renovations can vary widely depending on your home’s age, size, and condition. It’s smart to be honest about what you’re willing to spend—and leave some breathing room for the unexpected. A strong budget doesn’t just guide decisions; it keeps stress levels down.

Choose the right, vetted contractor

Who you hire matters. Look for someone with experience working on your type of home, whether a brownstone, a loft, or a prewar walk-up. At Block, we match homeowners with thoroughly vetted contractors, so you’re working with someone qualified, reliable, and familiar with Brooklyn buildings.

During renovation

This is where things start moving, and staying involved (without micromanaging) makes all the difference.

Protect your space and stay organized

Dust and tools tend to travel. Cover what you can, and set aside a clean zone for important items and paperwork. If you’re living at home during the renovation, discuss logistics upfront—what hours crews will be on-site, how they’ll access the space, and how you’ll manage the day-to-day.

Communicate regularly with your contractor

Don’t let things build up. Stay in the loop with regular check-ins, and make sure you know who to reach out to with questions. A good contractor won’t just expect this—they’ll appreciate it. Clear, consistent communication helps avoid missteps and keeps everyone aligned.

Track progress and stay informed

You shouldn’t be left guessing. At Block, we make sure milestones are clearly laid out, updates are shared in real time, and any changes or issues are flagged early. When you have visibility into what’s happening and why, you can make smarter, more confident decisions.

Compare Proposals with Ease

Easily compare contractor quotes with intuitive layouts, and side-by-side comparisons to help you make the best choice.

After renovation

The work may be done, but there’s still a bit to wrap up before it’s officially complete.

Walk through and check the finished work

Do a full walkthrough with your contractor. Go over the scope, inspect the details, and jot down anything that needs attention. This is your chance to catch small things now, not later.

Handle any final fixes

Even with the best team, touch-ups happen. Maybe a drawer needs adjusting, or paint touch-ups, in order. A solid contractor will take care of those without hesitation—it’s part of the process and matters.

Enjoy your new, personalized space

This is why you did it. Whether cooking in a kitchen that finally works for your routine or relaxing in a bathroom that doesn’t feel like a squeeze, this is your home—updated, refined, and shaped around your life.

Brooklyn neighborhood insights

Brooklyn isn’t a one-size-fits-all borough. Every neighborhood has its character and renovation challenges, from cobblestone blocks to converted factories. That means what works in a Park Slope brownstone might not apply in a DUMBO high-rise, and renovating a historic Crown Heights home will feel different from designing a sleek Greenpoint loft. Here’s a closer look at what to expect in some of Brooklyn’s most renovation-active areas.

DUMBO & Downtown Brooklyn renovations

In DUMBO and Downtown Brooklyn, you’re more likely to be renovating within a condo or high-rise. These spaces often have great bones—modern layouts, incredible views—but they come with strict building regulations and shared infrastructure.

Expect to navigate clear guidelines around plumbing changes, flooring materials (for soundproofing), and work hours. Some buildings may even require you to submit specific product details or design plans for approval before work can begin. Streamline this process by ensuring your scope is board-friendly and your contractor understands the building’s rules before day one.

Park Slope renovations

Renovating in Park Slope often means working with classic brownstones and townhouses. These homes are charming—ornate moldings, original fireplaces, and sweeping staircases—but updating them requires a thoughtful touch.

Many blocks fall within historic districts, meaning exterior changes must be approved by the Landmarks Preservation Commission. Interior renovations also need to consider structural integrity and outdated systems. 

Williamsburg & Greenpoint renovations

In Williamsburg and Greenpoint, the housing stock leans more industrial and modern. Think open-plan lofts, converted warehouses, and newer condo developments. Renovations in these neighborhoods often prioritize smart layouts and efficient design, especially when space is tight.

Small bathrooms and kitchens are common, including creative storage, multi-functional fixtures, and lighting strategies that maximize every square foot. 

Brooklyn Heights & Cobble Hill renovations

These neighborhoods are known for their tree-lined streets and historic charm. Many homes here are part of designated historic districts, so renovations, especially those involving facades, windows, or rooftops, need to comply with LPC guidelines.

At the same time, interiors often require modern updates, from better insulation to updated kitchens and baths. The challenge is keeping what makes these homes special while enhancing their livability. 

Bed-Stuy & Crown Heights renovations

These neighborhoods are full of historic townhouses with original features that deserve to be restored, not removed. From woodwork and fireplaces to stained glass and plaster details, the craftsmanship in these homes tells a story.

Block supports homeowners who want to honor that legacy while updating systems and layouts for modern life. In many cases, that also includes renovating basements—whether to create extra living space, a guest suite, or a rental unit. From waterproofing to egress requirements, we help ensure every step is up to code and built to last.

Real Brooklyn transformations

What is the best way to understand what a Brooklyn renovation can achieve? See it for yourself. From compact bathrooms to full kitchen overhauls, real homeowners across the borough have transformed their spaces with Block, creating homes that reflect their lives, needs, and neighborhoods. These are just a few examples of what’s possible when thoughtful design meets expert execution.

A serene bathroom upgrade in Clinton Hill

Before: This Clinton Hill bathroom showed its age, with outdated tile, a cramped tub, and minimal storage, making the space feel more functional than calming.

After: With help from Block, the homeowner created a light-filled, spa-inspired retreat that feels like a breath of fresh air. A floating vanity adds visual space, while a frameless glass shower, modern fixtures, and soft, neutral tones bring an elevated sense of calm to a once-cluttered room. The layout remains compact, but every inch now serves a purpose.

A modern refresh in Prospect Lefferts Gardens

Before: Tired finishes and poor lighting made this bathroom dark and dated. The original layout didn’t maximize space or storage—common pain points in Brooklyn prewar buildings.

After: Block worked with the homeowner to reimagine the space with brighter materials and a more efficient design. Matte black fixtures and sleek tile add a modern touch, while built-in shelving and a floating sink free up precious square footage. The result is a current and classic bathroom—proof that even smaller spaces can make a big statement.

A bold kitchen overhaul in Williamsburg

Before: The original kitchen in this Williamsburg apartment lacked style and storage, mismatched cabinetry, outdated appliances, and limited counter space, making it feel disconnected from the rest of the home’s industrial-modern aesthetic.

After: The transformation is dramatic. Block helped the homeowner create a sleek, cohesive kitchen with flat-panel cabinetry, quartz countertops, and upgraded appliances. A new layout added both flow and functionality, while a mix of open shelving and concealed storage keeps things organized without feeling closed in. It’s now the kind of kitchen that invites people in and holds up to everyday life.

Whether you’re looking to bring more light into a bath, modernize your kitchen without losing character, or finally make your space work for how you live, Block is here to help you bring that vision to life.

Expert guidance

No two renovations are alike, and navigating the process alone can feel overwhelming, especially in Brooklyn, where each neighborhood (and building) has its quirks. Block brings deep expertise to every phase of the journey. From planning and budgeting to design decisions and construction oversight, our team helps you understand what to expect and how to make wise choices. You’ll get a clear sense of your options and the trade-offs involved, so you’re not left guessing or second-guessing. It’s expert support designed to meet you where you are, whether it’s your first renovation or your fifth.

Clear pricing and scope

One of the biggest stressors in any renovation? Uncertainty. Vague quotes, missing line items, and last-minute changes can quickly derail your budget and timeline. At Block, we believe in full transparency from day one. That starts with our Renovation Planner, a free tool that helps you visualize your space and receive accurate, real-time cost estimates based on your style and layout.

Once you’re ready to move forward, Block helps you define a detailed project scope and receive competitive quotes from vetted contractors. Our expert scope review flags anything that might be unclear, missing, or problematic, so you can move forward with confidence knowing exactly what you’re getting (and paying for).

Personalized renovations

Your home should reflect you, not a one-size-fits-all template. Whether you're reimagining a Park Slope brownstone, updating a condo in DUMBO, or modernizing a prewar co-op in Prospect Heights, Block helps you bring your unique vision to life. We guide you through materials, layouts, and design decisions that align with your goals and how you actually live. Every renovation is tailored to your style, your home’s architecture, and how you want to use your space—no generic packages here—just thoughtful, individualized planning that leads to a home you love.

Secure payments

Money matters in renovation, and how it moves can impact your peace of mind just as much as your budget. With Block, you don’t pay your contractor directly. Instead, we provide a secure payment system that holds funds until key project milestones are met. Payments are only released as work progresses, keeping everyone accountable and aligned on timing. This protects your investment, avoids awkward money conversations, and ensures that your contractor stays motivated to deliver quality work on schedule.

Renovating in Brooklyn is a big decision. But with Block, it doesn’t have to be a risky one. We combine smart tools with trusted human expertise to make every step more transparent, personalized, and empowering.
