Home Additions & Extensions in Oshawa
Expand Your Oshawa Home with a Professionally Built Custom Addition

Whether you want to add a new room, enlarge your main floor, build a second storey, or add an extension that integrates with your home’s style, 905 Reno delivers premium additions designed for comfort, aesthetics, and long-term value.
