ICF Home Builder in Markham, ON
Concrete-Core Homes Built for Markham’s Established Neighbourhoods
Insulated concrete form construction engineered for Markham’s mix of heritage-adjacent and established residential lots — built by one accountable team from feasibility through occupancy.
ICF Construction in Markham
As an ICF home builder, we integrate the wall system into your architectural planning from the earliest design stage, then carry that same team through permits and construction. Markham neighbourhoods near corridors like Highway 7 and Woodbine Avenue benefit from ICF’s sound dampening, while heritage-adjacent areas around Unionville require the same design sensitivity as any custom build in that district — we help you weigh both for your specific site. See our ICF Construction page for the full process.
Why Markham Homeowners Choose Modinno
ICF construction only delivers its performance advantages when the structural engineering and municipal approval process are handled correctly from the outset. Homeowners choose us for genuine ICF experience, not a wood-frame team adapting on the job.

Site-first planning
Zoning, heritage designation, and lot conditions reviewed before ICF-specific structural design begins.

Architect, structural engineer, and builder working from the same plan throughout.
Building science as standard
Continuous insulation and airtight construction paired with properly sized mechanical systems.
How We Handle Permits & Approvals for Markham ICF Homes
We manage your ICF home through the same zoning, site plan, and building permit process as any new Markham custom home, plus the additional structural documentation the wall system requires. Where your property sits within the Unionville Heritage Conservation District, we secure the same additional heritage design review as any custom build there, regardless of wall system.
Frequently Asked Questions
Is ICF construction available for custom homes in Markham?
Yes, and we manage the additional structural engineering it requires as part of every project — the underlying zoning and permit process is the same as a wood-frame custom home.
Is ICF a good fit for homes near Markham’s busier corridors?
Yes — we often recommend it for homeowners near Highway 7 or Woodbine, since the continuous insulation and mass of an ICF wall assembly typically provide noticeably better sound dampening than wood-frame construction.
Does building with ICF change my Markham permit timeline?
Not significantly — we complete the ICF-specific structural engineering before permit submission, so the municipal review process moves on the same timeline as a wood-frame home.
Can ICF be used for a custom build near Unionville’s heritage district?
Yes, and we manage that heritage review alongside the ICF-specific structural documentation as one coordinated process, regardless of wall system.
