High-End Renovations • Condo Transformations • Multi-Family Value Add • New Construction
At CZ Construction Management, we specialize in high-end residential renovations, condo conversions, new construction, brownstone remodels, and multi-family value-add projects throughout Boston, and greater Boston
Our management-driven approach focuses on:
• Transparent budgeting from day one

Most CZCM projects begin around $20,000–$75,000 for single-room renovations and range into $300,000–$2,000,000+ for full gut renovations, additions, and multi-family build-outs.
Understanding typical cost ranges allows you to make confident decisions early and ensures every project starts with clarity, structure, and realistic expectations.
Getting Started
Kitchen Renovations
Kitchens are typically one of the highest-cost areas in a home due to the number of trades involved (10–15+), material selections, and structural/layout changes.
Full Gut Kitchen Renovation
(Down to studs, all new mechanicals, layout changes, custom cabinets)
$70,000 – $150,000
High-end versions with structural reframing or luxury cabinetry:
$150,000 – $250,000+
Partial Kitchen Remodel
(Keeping layout, updating finishes, counters, new appliances)
$40,000 – $85,000
Typical cost drivers:
• Custom or European slab cabinetry
• Quartz or stone countertops
• New electrical service & panel upgrades
• Structural changes (opening walls)
• High-end appliance packages
• Flooring replacement across multiple rooms
Your kitchen is the centerpiece of your home — and the most critical room to get right.
Bathroom Renovations
Bathrooms are mechanically dense and finish-heavy spaces. Labor, waterproofing, tile work, plumbing reconfiguration, and specialty materials drive pricing.
Powder Room (Half-Bath)
$20,000 – $35,000
Full Bathroom
(Tile shower OR tub, vanity, plumbing upgrades)
$25,000 – $50,000
High-End or Primary Bathroom
(Walk-in shower + tub, luxury tile, heated floors, custom vanity)
$50,000 – $120,000+
Bathroom Details
Cost factors include:
• Linear drains and specialty waterproofing
• Custom tile patterns
• Heated flooring
• Relocating plumbing fixtures
• Ventilation and electrical upgrades
• Adding recessed lighting or luxe fixtures
Primary bathrooms often require structural or plumbing upgrades—leading to the highest cost of all bathroom types.
Whole Home Renovations
Full home remodels allow the most efficient sequencing and best long-term value by addressing structure, systems, and finishes at once.
Example:
A 2,000–3,000 sq ft Boston single-family or brownstone gut renovation including:
Full kitchen + bathrooms
New electrical, plumbing, and HVAC
Insulation + drywall
Flooring, trim, and doors
Layout changes or light structural work
New siding, trim and roof
Typical Range: $250–$450+ per square foot depending on scope and finish level.
Additions + Structural Work
Boston’s older housing often requires:
• Structural reframing
• LVL beams
• Foundation modifications
• Layout reconfiguration
Home Additions
$350 – $600+ per sq ft
(Boston & Newton typically fall between $400–$650/sf)
Interior Gut Renovations
$250 – $450+ per sq ft
Decks, Porches, Roof Decks
$200 – $450+ per sq ft
(Roof decks with steel often exceed $500–$700+/sf)
MULTI-FAMILY + CONDO CONVERSIONS

3- and 4-Unit Value-Add Renovations
$450,000 – $1.5M+
Structural and mechanical upgrades often required.
New Construction

Example:
Ground-up single-family home or urban infill build including:
Site work and foundation
Full framing and structural package
High-performance building envelope
Complete mechanical systems
Custom kitchen, baths, and finishes

Kitchen and full bathroom
