The housing market is tough for young adults. With rising property prices and cost of living, saving for a deposit can feel impossible. This is where a teenage annexe comes in.

What is a Teenage Annexe?

A teenage annexe is a self-contained living space built in your garden, perfect for your growing child. It offers them the privacy and independence they crave while keeping them close to home. And giving you all some much-needed space!

Benefits of an Annexe

  • Save for a deposit: An annexe lets your teenager live at home while saving for their own home. This is especially important in today’s market where property prices are soaring.
  • Promote independence: Teenagers crave independence. An annexe provides a space for them to learn responsibility and life skills like cooking and laundry.
  • More space and privacy for Everyone: Teenagers can be loud! An annexe creates a separate living area, giving everyone in the house more space and privacy.
  • Potential investment: Studies show annexes can increase property value by 20-30%. It’s a great investment for the future.
  • Potential for multigenerational living: Maybe you envision living with your child in the future. An annexe can be designed for flexibility, adapting to your family’s needs.
  • Reduced cost of living: Compared to renting an apartment, an annexe can be a more affordable option for your teenager.
