Luxury custom home builder · Greater Toronto Area

Custom Home Builders Mississauga Since 1995

Q: How much does it cost to build a custom home in Mississauga?

The cost depends on your home size, design, materials and finishes. GrandBuild Homes publishes fixed starting ranges: Signature Series $350-450 per square foot and Estate Series $450-800+ per square foot, itemized line by line before we break ground. A typical 3,000 sq ft Signature Series home starts from about $1,050,000 for construction scope.

Q: How long does it take to build a custom home?

Timelines vary based on design, approvals and project complexity. We provide a realistic schedule for your custom home build before construction begins, and manage the design, permit and approval stages so you are not chasing the city.

Q: Do you handle permits, architecture and engineering?

Yes. We manage permits, engineering and approvals in house with experienced custom home designers. Zoning, engineering, conservation authority and municipal approvals are all ours to manage across Mississauga and the GTA.

Q: What areas do you build custom homes in?

We build across Mississauga and the Greater Toronto Area, including Oakville, Burlington, Toronto, Etobicoke, North York, Vaughan, Brampton, Richmond Hill, Caledon and King City.

Q: Can you help me find land or assess my property?

Yes. We review properties, assess building potential and help you make informed decisions before starting your project. Most of our clients come to us before they own the land, and we help find the property and sell the home you are in.

For the last 3 decades we have been the top choice for families’ dream homes across the GTA. From start to completion, we manage, design, approvals, construction, and finishing with one dedicated team.

What We Build in Mississauga and GTA

Everything Under One Contract

Custom home builds

New homes from the lot up, designed and built end to end. As an HCRA-licensed builder, every home we deliver is registered with Tarion and covered by the Ontario New Home Warranty, architecture, permits, construction and finishes all under one contract.

Home additions and expansions

Second storeys, rear additions and structural expansions. We handle the zoning review, Committee of Adjustment application where a minor variance is needed, and the building permit, then build around the home you are living in.

Basement and income suites

Legal secondary units, walkouts and finished lower levels. Ceiling heights, egress windows and fire separation are built to the Ontario Building Code and inspected, so the unit is legally rentable the day it is finished.

Garden and secondary suites

Detached garden suites and Additional Residential Units (ARUs). We check your lot against current zoning and, where required, conservation authority approvals before you commit, then build to the Ontario Building Code.

Home Renovations

Full-house renovations and kitchen and bathroom rebuilds. One team through demolition, mechanical, drywall and finishes, with a fixed written scope and schedule before we start, no allowances that quietly grow.

Insurance and fire restoration

Rebuilds after fire, flood and structural loss. We work directly with your adjuster on scope and pricing, and bring the property back to current Ontario Building Code, not just back to what was there.

Real estate investment projects

Build-to-sell and build-to-rent for investors and developers. Budgets, timelines and finish levels set against your return, with HST and closing costs accounted for from day one.

Land and property

Help finding a lot to build on, and selling the home you are in. We review sites for buildability, zoning, setbacks, servicing and conservation constraints, before you put an offer in.

How a Custom Home Build Runs

Six Steps. One Point of Contact

The lot

Have one, or need one. We help you find land across Mississauga and the GTA, and sell the home you are in. Then we stand on the property together and tell you what it will realistically take, before you commit to it.

Design

Architectural drawings developed around the lot, the zoning and how you actually live. You see the home before it is built, and you sign off before anything moves forward.

Permits and approvals

Zoning, engineering, conservation authority and municipal approvals are ours to manage. Thirty years as a custom home builder in Mississauga means we know which desk your file lands on. You are not chasing the city.

Fixed price

Your number is itemized line by line and agreed before we break ground. No moving target, and no allowances that quietly grow.

Build

One team on site, one schedule, one person you call. Clean, organized, and inspected at every stage.

Handover

Final walkthrough, deficiencies closed, Tarion warranty registered and your 30-day form filed. Then we stay reachable, the way a builder should be after handover.

Land First? We Handle that Too

Most of our clients come to us before they own the land. We help you find the property, sell the home you are in, and tell you what a lot can actually support, before you put an offer in.
