Adding value to a property with a garage conversion
Converting a garage into a self-contained granny flat or extra room can add significant value to a property.

AI summary
Converting your garage can significantly add value, whether as an extra room or a self-contained granny flat. Before starting, assess suitability, including ceiling height (min 2.4m) and alternative parking options.
Building consent is almost always required to change a non-habitable space. Adding a kitchen to create a minor dwelling will likely also need resource consent, so always check with your local council.
Key changes include waterproofing floors, replacing the garage door, and ensuring proper ventilation. This investment can boost your property's appeal and final sale price.
