Frequently Asked Questions

  • What can a granny flat be used for?

    A granny flat can be used in a variety of ways depending on your needs. It’s commonly used for extended family members, such as parents or adult children, but it can also serve as guest accommodation, a home office or a private retreat. Some homeowners use granny flats as rental properties, providing an additional income stream. The flexibility of the space is one of its biggest advantages, as it can adapt over time as your circumstances change.

  • Can a granny flat have its own utilities?

    Yes, granny flats can be designed to have their own utilities, including water, electricity and sewer connections. This allows the space to function independently from the main house, which is especially useful if it’s being used as a separate living area or rental property. The setup will depend on the existing infrastructure on your property and how the new dwelling is designed.

  • Does adding a granny flat increase property value?

    In many cases, adding a granny flat can increase property value by providing additional usable space and flexibility. Buyers often see the benefit of having a secondary dwelling for family, guests or potential rental income. The overall impact on value will depend on factors such as design quality, location and how well the granny flat integrates with the rest of the property.
