Our Design-Build Services North York
Instead of hiring separate designers, contractors, and trades, you’ll work with one team that manages the project from planning through construction. That means no communication issues, better scheduling, and more accountability throughout the build.
Here’s an overview of the services we offer with a design-build approach:

Custom Homes North York
Building a custom home in North York gives you control over layout, storage, finishes, ceiling height, exterior style, and more. You’ll be able to add everything you need, such as an open layout, larger entertainment spaces, or aging in-place features. We’re with you at each stage, from lot purchasing, material selections, and inspections to the final walkthrough.

Semi-Custom Homes North York
Semi-custom homes give you more design opportunities than a standard build without the added cost of a full custom build. This is a good alternative for anyone looking to reduce construction timelines while still adding character to the overall design.

North York Full Home Renovations
Many older homes in areas such as Lansing, Bathurst Manor, and Armour Heights have closed layouts, small kitchens, limited storage, and dated finishes. We renovate entire homes to improve flow, update interiors, and upgrade outdated systems. As part of our design-build service, we manage demolition, permits, scheduling, and trade coordination throughout the process.

Home Additions North York
When you outgrow your home, it doesn’t always have to end in a big move. Rather than leaving your desired neighbourhood, we can help you design and build the extra space you need. This includes rear-home extensions, kitchen expansions, bathroom additions, single-room additions, and second-storey additions.

Commercial Renovations North York
We renovate and maintain a variety of commercial properties in North York. We understand the unique demands for spaces to function unilaterally for staff, customers, and daily operations. Dysfunctional layouts, poor lighting, and aging finishes can affect workflow, appearance, and experiences.
We renovate offices, restaurants, medical clinics, dental offices, gyms, and retail spaces with durable materials and practical layouts built for long-term use.
For larger properties, including low-rise buildings and hotels, we also provide ongoing property maintenance through the same team that renovated and understands the property inside and out.
Why Choose Jash Design & Build
