Klein’s Custom 3-Step Brownstone & Townhouse Renovation Process
We make renovating your NYC brownstone or townhouse simple, transparent, and stress-free—from the first design meeting to the final walkthrough
PHASE 1
Design & Planning
Every great renovation begins with a vision. During this phase, our team visits your home for an in-depth consultation—measuring, assessing structural and mechanical systems, and understanding how you live. We’ll develop a custom layout and detailed brownstone townhouse plan, tailored to your style, budget, and the character of your home. You’ll review design mockups, finishes, and materials with your dedicated designer while we outline estimated costs, project timeline, and any LPC or DOB requirements before construction begins.
PHASE 2
Permits, Materials & Selections
Once the design is finalized, we handle every step of the approval process—preparing architectural drawings, managing NYC landmark permits, and coordinating with neighbors when access is required. At the same time, you’ll work with our design team to choose premium materials, fixtures, and finishes that complement your brownstone’s architectural charm. From handcrafted cabinetry and stone to lighting and flooring, every selection reflects both function and aesthetic harmony.
PHASE 3
Construction & Restoration
With all permits approved, our licensed brownstone renovation contractors get to work. Our expert builders and craftsmen restore, reconfigure, and modernize your space with precision and care—whether it’s a full Brooklyn brownstone renovation or a multi-level townhouse remodel in Manhattan. We maintain protected work zones, manage daily progress, and keep communication open through on-site supervision and frequent updates. The result is a beautifully restored home that blends historic character with modern comfort and long-term durability.
THE FINISHING TOUCHES
At Klein Kitchen & Bath, every detail matters. After final inspections and quality checks, we walk you through your newly completed brownstone or townhouse, ensuring every finish and fixture meets our exacting standards. You’ll receive maintenance guidance, documentation, and warranty coverage for peace of mind. From elegant brownstone façade restoration to reimagined interiors, our NYC townhouse renovation process transforms historic properties into homes built for modern living.
Permits, LPC & Compliance
Navigating permits and landmark approvals in New York can be complex—especially for brownstone and townhouse renovations. At Klein, we handle every step, ensuring full LPC and DOB compliance throughout the whole process.
When LPC applies:
Landmarked buildings or within historic districts require LPC review for exterior work (and sometimes visible interior changes).
Common filings:
DOB Alt 1/2, LPC Staff vs Commission review, after-hours variances when needed.
Neighbor access:
We help with agreements and scaffold planning to keep schedules on track.
What you do:
Approve design; we handle the paperwork.

Design Details That Matter in Brownstones
Our team specializes in optimizing brownstone and townhouse spaces—designing layouts that enhance light, storage, and livability while honoring each home’s architectural integrity.
• Light strategies for narrow layouts: open stairs, glass transoms, and borrowed light to brighten every level.
• Smart storage in compact footprints: custom millwork, stair drawers, and built-ins that make use of every niche.
• Improved acoustics and privacy: resilient channels, mineral wool, and soundproofing between shared walls and floors.
• Durable, reversible detailing: period-appropriate trim, mantels, and flooring restored or recreated with precision.
• Energy efficiency and indoor air quality: ERVs, air-sealing, low-VOC finishes, and balanced ventilation systems for healthier living.
