What Our Trusted
Clients Saying
Highly rated by homeowners and property owners across the GTA.




Fully Custom Homes
A custom home is a new home designed completely from scratch, with fewer design and construction limitations. This option gives you full flexibility to create a home around your lot, lifestyle, layout preferences, and long-term goals.
You can customize floor plans, ceiling heights, finishes, materials, architectural details, and specialty features. For example, you may choose a 12 ft main floor, a 20 ft basement, premium finishes, custom millwork, and other high-end design elements.
At Jash Design & Build, the cost of a custom home typically ranges from approx. $400 to $500 per sq. ft.
Semi Custom Homes
A semi-custom home is a new home built similar to build-grade construction with some pre-built or modular elements i.e. pre-built frames, instead of being designed completely from scratch. There are some design and construction limitations, but the timeline can be shorter — for example, around 8 months instead of roughly 12 months for a fully custom build.
You can still customize floor plans, finishes, materials, and design details, but there are some limits to what can be changed. For example, ceiling height for the main floor will be approx. 10 ft high, but not 12 ft high (this is custom).
At Jash Design & Build, the cost of a semi custom home starts at approx. $320 per sq. ft.
