JDC Custom Homes Inc. — Custom Home Design-Build, Renovations & Additions in Orangeville, Dufferin County, ON
JDC Custom Homes (also operating as Janssen Design & Construction) is an Orangeville design-build firm that has been planning and building custom homes, large additions, and full renovations across south-central Ontario for more than three decades. The firm keeps interior and exterior design in-house, which is unusual at this scale — most regional builders subcontract the design phase entirely.

- Major renovations and additions — including substantial second-storey and rear additions on existing homes.
- Cottage builds — custom cottages in Wasaga Beach, Thornbury, Collingwood, Kincardine, and other cottage-country destinations.
- Interior design — material selection, finish specifications, space planning.
- Exterior design — facade, hardscape relationships, building envelope coordination.

Why it’s on home.renovation.reviews
JDC fits a specific profile that’s underrepresented in the directory — a design-build firm with both architectural and construction sides under one banner, and 30+ years of continuous operation. For homeowners trying to decide between hiring a separate designer and contractor, this kind of integrated shop is often a more predictable path. The Dufferin County renovation cluster is one of our densest in central Ontario and JDC sits naturally inside it.
