Turn Your Property Into a Multi-Unit Investment
Accessory Dwelling Units (ADUs) - often called Garden Suites, Coach Houses, or Secondary Suites - are one of the smartest ways to increase your property value, provide for family members, or generate rental income.
However, designing an ADU isn’t just about the layout; it’s about meeting strict municipal zoning bylaws and Ontario Building Code (OBC) requirements. At Nauta Home Designs, we specialize in creating functional, beautiful living spaces that are designed to be approved.
