A London builder since 2010.
Ironstone was founded in 2010 on a simple conviction: that London and the surrounding region deserved a homebuilder who put quality, honesty and community first. More than a decade on, we've become one of the most trusted names in new-home construction across London and Kitchener, Ontario.
Our founders, David Stimac and Allan Drewlo, brought together more than 50 years of combined homebuilding expertise from their respective companies, Stoneridge Homes Inc. and Drewlo Homes Inc. Between them they had already constructed more than 1,500 homes, and Ironstone became the place where that craft, discipline and care came together under one roof.


With a focus on quality, sustainability and forward-looking design, we don't just build houses, we create vibrant, welcoming communities designed for the way people actually live today.
The road from 2010 to today.
From two established London builders joining forces to four communities across two cities, here's how Ironstone grew.
The beginning
David Stimac and Allan Drewlo unite Stoneridge Homes and Drewlo Homes, bringing 50+ years and 1,500+ homes of combined expertise under one name.
Rooted in London
The first Ironstone communities take shape across the city, built on a promise of quality trades, honest pricing and a personal relationship with every buyer.
A new kind of home
Ironstone's adaptive home design, a layout that grows and changes with your family, earns the OHBA Innovation Award.

A commitment to give back to local charities, in a new and meaningful way every single year, becomes part of who we are.

Four promises behind every home.
Our mission hasn't changed since day one, build better homes, and treat the people who buy them the way we'd want to be treated.
Built to last
Construct high-quality new homes with superior trades and building materials, no shortcuts where they matter most.
Honest pricing
Include upgraded finishes in the base price and keep the entire home-buying process transparent, start to finish.
A real relationship

Care after closing
Provide the best customer care possible through our Warranty Program, long after the keys change hands.

Building more than homes. Every single year.
A homebuilder's responsibility doesn't end at the lot line. The communities we build in have given us so much, and since 2020, through Ironstone Impact, we have found a new and meaningful way to give back every year.
Our team has supported local and national organizations doing vital work close to home, from food security and family crisis support to health research and housing.
A new cause each year
Rather than spreading thin, we choose one focus annually and go deep with the people already doing the work.
Local first
The families who buy our homes live here. So the organizations we back serve London and southwestern Ontario.
Our trades come with us
Suppliers and trade partners match and multiply what we give, which is how one gift becomes two.
We show the receipts
Every campaign is documented and shared, so you can see exactly where it went and what it made possible.
