Adding an extension or new room to a semi-detached home is something many homeowners explore. What’s possible depends on the property layout, local bylaws, and how the new space connects with your current home. Backyard extensions, second-floor additions, terraces, and garage conversions are often considered options, but each one typically requires a review of the site and layout to understand what may be possible for your specific property.
