Remodeling Contractor in Richmond Hill

Rosmon Group is a remodeling contractor based in Oak Ridges, Richmond Hill. We remodel kitchens, bathrooms and basements, open up layouts and renovate whole homes and townhouses for families across Richmond Hill and York Region.

We plan the work around how you live, take care of the permits, and keep one team on the job from demolition to the final walkthrough — like the townhouse at 556 Bondi Ave in Newmarket and the family home at 41 Spring Home in Barrie.

Design-Build in Richmond Hill

Design-build means one company designs your project and builds it. Our designers and our construction team work together from the first sketch, so the drawings, the budget and the build stay aligned — and the design you approve is the one that gets built.

We take care of the architectural and interior design, the permit drawings and approvals, and the construction itself, so you are not coordinating an architect, a designer and a contractor separately.

  • A general contractor runs the whole job: plans the work and the schedule, hires and coordinates the trades — framing, plumbing, electrical, drywall and finishing — orders the materials, keeps the site safe, books the City inspections and makes sure the work meets the Ontario Building Code. At Rosmon Group our team does this on every renovation, so you deal with one company instead of a dozen trades.

  • With design-build, one company handles both the design and the construction. The traditional route is to hire a designer or architect first, then take the drawings to contractors for pricing — two teams, two contracts, and room for the plan and the price to drift apart. Design-build keeps the designers and the builders on one team from day one, so costs are checked while the design is drawn and one company is responsible for the result.

  • Kitchen, bathroom and basement remodels, condo renovations, home additions, whole-home renovations of houses and townhouses, and commercial fit-outs for offices, retail and hospitality spaces. We also design interiors and build new custom homes.

  • Look at finished projects similar to yours, ask who designs the work and who builds it, and check that the contractor takes care of building permits and inspections. Ask for a detailed written scope and price after a site visit rather than a quick number over the phone, and make sure you know who your contact is during the job. You can see our own work on the Projects page.

  • A design-build contractor can. Rosmon Group prepares the design and the permit drawings, applies for the building permit with the City of Richmond Hill or your municipality, and books the inspections during construction — the design, the paperwork and the build come from one team.
