DESIGN BUILD

Built for Hamilton Homeowners and Investors Who Want It Done Right

At Gateway, we specialize in transforming underused land and existing properties into modern, multi-unit homes that enhance your lifestyle and deliver long-term value. Our integrated Design-Bu

Building a home or adding to one is one of the largest decisions you’ll make. Most people spend months trying to find the right builder — only to discover mid-build that their contractor can’t close permits, can’t hold a price, or hands the project off to trades they’ve never met.

 

Gateway is built differently. We’re not just renovators — we’re Tarion-registered builders. That means we take full accountability from the first feasibility conversation through to final city sign-off. One team. Fixed-price contract. You know exactly what’s happening every active build day.

 

Whether you’ve just bought a property and want it transformed before you move in, or you’re building a new home, addition, or multi-unit build from the ground up — we guide the full process so you never have to chase a contractor, a permit, or an answer.

ild process brings feasibility, planning, design, project management, and construction together under one roof — so your project is thoughtfully designed, efficiently executed, and built to last.

  • Feasibility first — know what’s possible and what it costs before committing to anything
  • Full permit management — City of Hamilton submissions, inspections, and code compliance. You never visit the building department
  • Fixed-price contract — the number in your proposal is the number you pay. No change orders for things we should have caught at the start
  • One team, full scope — plans to permits to final walkthrough, no handoffs to trades you’ve never met
  • Daily WhatsApp updates — every active build day, so you always know exactly where your project stands
