Garages and granny flats can be used to store large, infrequently used items, outdoor supplies, seasonal decor or items that simply don’t fit inside the house. They can also be used as recreational rooms or can be converted into granny flats or studios, with sufficient ventilation, light and insulation. Use as a separate home office is on the rise, as is building self-contained granny flats which can be sub-let for passive income. Whatever your project is, take a look at this Houzz image gallery to see how you can maximise this often overlooked space. If you're looking to get started building or renovating yours, you'll be able to find the right architect to help get you started in our professional directory. If your granny flat should be self-contained, a kitchen designer may also be helpful.
