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

• Realistic cost ranges so clients can scope projects properly

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

2-Family → Luxury Condo Conversion

Typical Boston range:
$350,000 – $900,000+ depending on:
• Full gut requirements
• Floorplan redesign
• New HVAC + electrical service
• Roofing, siding, windows
• High-end kitchen/bath packages
• Condo egress and life-safety requirements

3- and 4-Unit Value-Add Renovations

$450,000 – $1.5M+
Structural and mechanical upgrades often required.

New Construction

New construction offers the highest level of customization and long-term performance. Building from the ground up allows full control over layout, structure, and energy efficiency.

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

Typical Range: $350–$800 per sq ft in Greater Boston depending on site complexity and finish level.

ACCESSORY DWELLING UNITS (ADUs)

ADUs are self-contained living spaces added to an existing property, often used for rental income, multigenerational living, or guest accommodations.

Example:
Backyard cottage, garage conversion, or internal apartment including:

  • Kitchen and full bathroom

  • Independent utilities

  • Private entry

  • Full insulation and code compliance

Typical Range: $275K – $650K depending on size, access, and structure type.
