Ironstone Building Company

What Ironstone Building Company does

Ironstone Building Company is a privately held residential home builder founded in 2010 by David Stimac and Allan Drewlo, operating primarily across Southwestern Ontario. The company develops spec/ready-to-go single-family homes and townhomes across five active communities — Summerside Trail, Summerside Trail II, The Grove, Jackson Meadows in London, and The Enclave at Jeffrey Place in Kitchener — with a parallel Ironstone Condos sub-brand offering townhomes and stacked-townhome products (Kai, Evans Glen, STAX). Construction uses conventional wood framing with energy-efficiency specifications (R22 exterior walls, R60 attic insulation, HRV systems, tankless water heaters), and several communities are ENERGY STAR certified or Net Zero Ready. Listed home prices range from roughly $377,184 (STAX after HST rebate) to $799,912.

Ironstone monetizes exclusively through one-time home sales at fixed prices, distributed entirely through a direct-to-consumer model using model homes, pop-up sales centres (e.g., 1067 Wellington Rd for STAX), a central London sales office (519-660-6006), and weekend open houses. The company differentiates on three proprietary programs: Ironclad Pricing (standard finishes included at base price), Flex Haus (single-family designs with a separate legal rental unit to offset mortgage costs, winner of the 2024 LHBA Innovation Award), and HomeStart ($100,000 interest-free deposit deferral for up to 10 years, expanded to all buyers in 2025). The Rent.Save.Own. program — a partnership with Drewlo Holdings providing $400/month (up to $15,000) of rent credit toward an Ironstone purchase, 2020 OHBA Innovation Award winner — generates a warm-lead pipeline that competitors lack.

The company is privately held with no external institutional investor disclosed, 11–50 employees, and consecutive recognition as London's Best Home Builder (2024 and 2025). Revenue is not publicly disclosed. The Ironstone Impact charitable giving program ($140,000 in 2024, $150,000 pledged in 2025) functions as both CSR and a community-led demand engine through weekly voting and earned media.
