Our Design-Build Services Vaughan
Our design-build method guarantees you have one accountable team from the planning stages to completion. The result is better coordination, better communication, and better outcomes. The following is a list of services we provide using our design-build approach:

Custom Homes Vaughan
We design and build fully customizable homes without template limitations. We design and plan architectural styles, layouts, and finishes to your vision and lifestyle. Custom homes are most common on large or redevelopment-ready lots, especially in estate areas such as Kleinburg, rural Vaughan, and select parts of Woodbridge and Thornhill.

Semi-Custom Homes Vaughan
Semi-custom homes have more design flexibility than a builder-grade home without the cost of a fully custom build. They’re a good fit if you want a modern layout and quality finishes without going through a full custom design process.

Full Home Renovations in Vaughan
Full-home renovations are common in Vaughan’s older housing districts, such as Woodbridge, Thornhill, and parts of Concord. Our turnkey renovations can help you address closed-off layouts, cramped kitchens and bathrooms, aging mechanical systems, and outdated finishes. You get to modernize your home with improved comfort and flow without having to leave your neighbourhood.

Home Additions Vaughan
Additions are perfect for growing and multi-generational families where moving isn’t ideal, but space has become an issue. This is especially common in older subdivisions throughout Vaughan. We handle the planning, design, demolition, building, and project management for additions. This includes second-storey additions, kitchen expansions, rear-home extensions, and more.

Commercial Renovations Vaughan
Jash Design & Build brings years of commercial construction experience to offices, restaurants, dental clinics, medical spaces, gyms, retail units, and larger properties. We design, build, and manage commercial renovations for empty shells and interior build-outs for:
- Office buildings
- Medical and dental clinics
- Restaurants
- Retail stores
- Low-rise residential buildings
- Plazas
- Hotels
- Gyms
One team, one process, and no missteps. We work around you and your schedule to minimize disruptions while delivering quality workmanship.
Additionally, we offer ongoing property maintenance from the same team who already knows your building inside and out. This is an add-on service for larger estate homes and commercial properties, including the type of large-scale properties we have built or renovated and understand inside and out.
