A Granny Annexe is a general term for various housing arrangements that allow an elderly relative to live in your home with maximum freedom and independence. Typically, a Granny Annexe is a self-contained unit attached to a house, complete with its own kitchen and bathroom.

Types of Granny Annexes

Here are some widely known and commonly used types of Granny Annexes:

Traditional Granny Annexe

A traditional Granny Annexe involves a section of a residential building that is separated from the rest of the house. This self-contained apartment includes a kitchen and a bathroom and may have its own entrance or share access with the main house.

Granny Flats

Granny flats are another popular type of Granny Annexe, especially in larger cities. This arrangement converts the downstairs of a house into a self-contained flat. Unlike traditional Granny Annexes, granny flats do not require an additional building to be connected to the house.

Ancillary Buildings

Ancillary buildings can be built on-site or pre-fabricated. This concept involves creating a permanent or temporary movable home in your garden. The ancillary building should be connected to the main house’s utilities, such as electricity and water supply. There are also examples of detached buildings being converted to accommodate elderly individuals.

Advantages of a Granny Annexe

This intergenerational living arrangement offers numerous benefits for everyone involved. Here are three major reasons why a Granny Annexe can be advantageous for your elderly relative:

1. More Time with Loved Ones
   Finding time to care for an elderly parent or relative can be challenging, especially with busy schedules. By moving them close to you, it becomes easier to spend quality time together—whether inviting them for dinner or chatting in the garden.
2. Cost Savings
   If your elderly relative has savings exceeding £23,250, they may not qualify for council support for care costs. A Granny Annexe provides a creative solution. For instance, proceeds from selling an old house can help fund care costs. Family members can also take turns caring for the elderly relative, reducing reliance on professional carers.
3. Greater Independence and Freedom
   A Granny Annexe allows for more control over the living arrangements of your elderly relative, giving them the freedom to personalise their space. This arrangement fosters a sense of independence that care homes often cannot provide.

How to Build a Granny Annexe

There are three primary methods to build a Granny Annexe for your elderly loved one:

1. Use Existing Rooms
   If your house is spacious enough, consider converting two or three extra rooms into a Granny Annexe without significant changes to the building. This option often does not require planning permission and allows for minimal disruption to your home.
2. Attach an Extension to Your House
   Extending your existing home is another cost-effective way to create more space. By connecting the extension to the original building, the Granny Annexe can feel more secluded.
3. Build a Detached Annexe
   If you prefer more separation between you and your elderly loved one, a detached annexe may be the best choice. Be sure to consider the number of bedrooms needed, especially if you plan to employ a live-in caregiver.
