Tarion Registered • BCIN Part 9 • Conservation Halton Liaison • $5M Liability + WSIB • GOHBA + OHBA • Since 2004 Custom Home Builder Oakville [/ →](/) provides luxury estate homes, waterfront residences, premium teardown rebuilds and full design-build service throughout Oakville and Halton, backed by 21+ years combined Oakville and Halton design-build. As a luxury custom home builder in Oakville, we measure success by one thing above all: the price and schedule you were promised are the ones you get. ## What Is Luxury Custom Home Construction? Luxury custom home construction covers the largest and most detailed homes we build, typically 5,500 to 10,000 sq ft. These homes are designed from a blank page, use engineered structure to create generous rooms, and integrate mechanical, lighting and audio systems from the earliest drawings. They are also the homes where small decisions add up fastest. A different stone, a larger window, a second island: each is reasonable on its own, and together they can move the budget by hundreds of thousands. That is why our luxury builds run on line-item allowances and written approvals for every change. ## Types of Luxury Homes We Build ### Waterfront and ravine estates Lake Ontario, Bronte Creek and Sixteen Mile Creek lots, where engineering and views shape the plan. Our Bronte Creek ravine residence, 5,200 sq ft at $2.89M, was redesigned around the staked top of bank before purchase. ### Georgian and traditional estates Indiana limestone, slate and copper on larger lots in Eastlake, Morrison and Old Oakville. Formal front elevations with open, light-filled rear living spaces. ### Modern estates Structural steel, curtain wall glazing and cantilevers, designed carefully around Oakville’s height rules. ## When Does a Project Move Into the Luxury Tier? Usually when the home exceeds about 5,500 sq ft, when the design needs structural steel or long spans, when the exterior uses natural stone throughout, or when the systems include hydronic heating, lighting control and whole-home audio. Many waterfront and heritage-district homes also land here because of their engineering and material requirements. ## How Much Does a Luxury Custom Home Cost? | Component | Typical range | Notes | | --- | --- | --- | | Structural steel and engineered framing | $60K-$250K | Open spans, cantilevers, tall ceilings | | Window package | $150K-$500K | Marvin Signature, curtain wall, steel-look | | Exterior stone and slate | $120K-$450K | Indiana limestone, natural stone, slate roofs | | Hydronic heating + ERV | $60K-$180K | Zoned radiant, Zehnder ERV | | Lighting control + AV pre-wire | $40K-$150K | Lutron HomeWorks, integrated audio | | Kitchen and appliances | $120K-$350K | Sub-Zero and Wolf or equivalent | Overall, our luxury homes typically run $2.5M to $6M. ## Which Standards Apply? Luxury homes follow the same Ontario Building Code Part 9 framework as any house, though larger spans often call for engineered steel and connections designed by our structural engineer. Our standard envelope meets Toronto Green Standard Tier 1 for Net Zero Ready qualification even at this scale, which matters in large homes where heating loads can otherwise be significant. STC-rated wall and floor assemblies keep bedrooms and media rooms quiet. Zoning By-law 2014-014 sets the envelope, and on waterfront or heritage lots Conservation Halton or Heritage Oakville review applies. Every home is enrolled with Tarion for the 7-year structural warranty. ## Luxury Builder vs General Contractor With an Architect With separate architect and contractor contracts, upgrades and changes often arrive as change orders with little warning. With our design-build approach, the person pricing the change sits in the design meeting. You decide with the number in front of you, and the decision is recorded. One project manager carries it through to installation. Written Pricing ## How Much Does Luxury Homes Cost in Oakville? Typical ranges for premium Oakville homes.

Our luxury custom homes in Oakville typically run $2.5M to $6M for 5,500 to 10,000 sq ft, which works out to roughly $575 to $750 per square foot depending on structure, exterior materials and systems. The biggest swings come from structural steel for open spans, natural stone exteriors, large window packages, hydronic heating and integrated controls. Waterfront and ravine lots add engineering. Every allowance is written into the contract, so if you upgrade the stone or the kitchen, you see the cost in writing and approve it before anything is ordered. Land, HST and development charges are separate. ### What makes a home luxury rather than standard custom? Mainly three things: scale, structure and systems. Luxury homes are larger, use steel or engineered framing to create long spans and tall ceilings, and include premium mechanical and control systems such as hydronic radiant heat, Zehnder ERVs and Lutron HomeWorks. Finishes are custom rather than chosen from a selections program, and acoustic separation between rooms is designed in. ### How long does a luxury custom home take to build? Typically 14 to 20 months of construction after a 16 to 20 week design and permit phase. Larger homes, complex structures and long-lead items like custom windows push toward the longer end. We order long-lead items during permits to keep construction moving. ### Do you build luxury homes on waterfront and ravine lots? Yes. Many of our luxury homes sit on Lake Ontario, Bronte Creek or Sixteen Mile Creek lots. Those lots add Conservation Halton permits and geotechnical design, which we handle in-house. ### How is the price kept fixed on a luxury build? By writing everything down. The contract lists every line item and allowance. Changes are priced and approved in writing before ordering. That is how Robert H.'s stone upgrade was handled on his $3.72M Eastlake Georgian. ### Can I bring my own interior designer? Yes. Many luxury clients do. We coordinate with your designer on drawings, schedules and allowances so their selections are priced and installed correctly. ### Who manages my luxury build day to day? One dedicated project manager from consultation to occupancy: one phone, one email, one contact through all 14-20 months. ### Are luxury homes covered by Tarion? Yes. Every new home we build is enrolled with Tarion and carries the 7-year structural, 2-year mechanical and 1-year workmanship warranty.
