Brooklyn’s architectural diversity means renovation costs vary wildly depending on your apartment type. Whether you are breathing new life into a prewar classic, an industrial loft, or a brownstone, understanding the financial commitment upfront prevents sticker shock midway through your project. Here is what you will actually spend renovating these three iconic Brooklyn apartment styles—and why the price tags look so different.
Prewar Apartments: Charm Meets Complexity
Brooklyn prewar apartments built before 1940 have high ceilings, elaborate cornices, and beautiful hardwood floors. However, behind the beautiful designs lurk outdated systems that drive renovation costs higher than newer construction.
Cost Range: $250-$300 per square foot
Here’s what impacts your bottom line:
Electrical upgrades: Most prewar buildings need complete rewiring to handle modern appliances and tech. This adds $8,000-$15,000 to your budget.
Plumbing overhauls: 1920s style, galvanized pipes? They are probably corroded and need replacing ($10,000-$20,000)
Hidden structural surprises: Cracked plaster, deteriorating joists, and outdated framing mean contingency budgets are non-negotiable
But hey, those original details like crown moldings and herringbone floors? They’re worth preserving. Refinishing, instead of replacing, can save the historical integrity. This will run you $5,000-$12,000.
Loft Conversions: Open Space, Open Wallets
Industrial lofts have that sought-after open concept living style, but converting the raw or semi-finished spaces to functional homes requires big investments.
Cost Range: $350-$550 per square foot
Why Lofts Cost More
Creating livable spaces from commercial buildings means building from scratch in many cases. You’re not just updating—you’re constructing bathrooms, kitchens, and bedroom partitions where none existed.
Factors that escalate loft renovation costs:
- HVAC installation: Open floor plans demand powerful systems to heat and cool efficiently—expect $15,000-$30,000 for ductwork and units
- Soundproofing: Exposed ceilings and concrete floors amplify noise, requiring acoustic treatments ($8,000-$20,000)
- Custom millwork: Built-in storage solutions maximize vertical space in high-ceiling lofts, running $12,000-$25,000
The exposed brick, massive windows, and soaring ceilings justify the premium. Plus, fewer load-bearing walls mean you’ve got flexibility in your layout—just don’t skimp on your architect’s fees.
