Benefits of Having a Garden Annex

Choosing to invest in a garden annex comes with many benefits that caters to various needs. 

1. Property Value Appreciation

Adding a high-specification garden annex can significantly increase the value of a UK property. The versatility and extra living space it provides are highly desirable features for prospective homebuyers.

2. Versatility and Functionality

An annex can serve as a guest room, workspace, or living area. By creating a clear separation between professional and personal life, it offers a more balanced work-life experience.

3. More living space

Homeowners can gain more space with a garden annex without the upheaval and expense of a loft or rear extension, which can be very costly and disruptive to the family. This is particularly beneficial when space in your home is limited.

4. Family Support

Being close to family significantly enhances the well-being of elderly members. They can easily access emotional support, companionship, and help with daily tasks. This support network can profoundly impact their quality of life.

There are many ways adding a garden annex can benefit your home life.

It provides a place for someone to live, with their own kitchen and bathroom. This makes it ideal for elderly relatives who may need somewhere to stay, or makes the ideal spot for children to have a space of their own when returning from university.

An annex can work as an apartment right in your garden, with all the comforts needed to get a good nights sleep, a wash, and have something to eat. 

This makes it the ideal way to host guests, and even could become a business prospct on a website such as AirBnB.

As the prices for things such as loft extensions get higher and higher, having a garden annex is a cost-efficient way of adding more living space to your home.

Additional living space in your home

If you need to care for elderly relatives permanently, but don't have the space in your property, then our Granny annex is the perfect solution.


When you have people over, for a weekend, provide them with their own space where they can stay comfortably.

Add Value

A garden annex should be seen as a great investment, as adding one of these to your home is like adding an extension, and is proven to increase the value of your property.

Create a New Business Opportunity

An annex provides everything anyone will need to stay. From kitchens to bathrooms, you're sure to have plenty of interested guests if you use it as holiday accomodation.
