Or Garden Annexe as it is also known. What is it exactly and what are the benefits?

A Granny Annexe is a fully self-contained dwelling, that can be built separately to the main building/house or interconnecting within the property. The primary use of this building is usually to allow a beloved parent or parents, who are now ageing and require daily care, to be close to their family for convenience and security.

There are also other family circumstances and requirements that would dictate how the annexe is used. An annexe allows for the ever-changing family landscape, where living requirements can differ each year. Typically, an annexe can afford the much-needed freedom to the teenager or early twenty-something, who needs their space and privacy, but may be finding it difficult to enter the housing market themselves.

Overall, the charm of a Granny or Garden Annexe is the ultimate separation, tranquillity and privacy that is afforded to all parties of the household, whilst retaining that strong link to the heart of the main home.

Do I need planning permission for a Granny Annexe?

Yes. A Granny Annexe that is inhabited on a daily basis will need planning permission or a Certificate of Lawfulness from your Local Planning Authority. Swift can help you with this, we have a team of specialists and a 100% success record in achieving planning permission – See our design & build page here

Does a Granny Annexe add value?

Yes. Whilst there are many variables that will dictate the true value of your property, average estimates are that you can expect up to 30% to be added to the value of your existing home. This is further bolstered by the ever-popular demand for properties with an additional building. The multi-functional use and self-containment of granny annexes ensures that they are an attractive extra property feature for many prospective buyers.

Can I put a Granny Annexe in my garden?

Absolutely. In most cases, this is the best position for such a dwelling, thus affording the privacy and space that is mostly sought after. Space permitting and provided that the correct planning permission is in place, of course.

How much does a Granny Annexe cost?

At a very brief overview, the costs of building a granny annexe can vary considerably. Swift pricings range from around £50,000 to over £100,000. The most important considerations and those that would have a dramatic effect on costs, would be;

• The location

• The intricacy of the design

• The size of the annexe

In general, your costs will mostly consist of the key requirements for such a dwelling. Planning permission and related planning application fees, design/architect fees, compliance with building regulations and construction/contractor fees.

We have an excellent pricing table here on our Prices page to guide you with this, including a list of options and upgrades you may want to consider.

How long will it take to build?

“My Swift Garden Room has been my permanent home for the past 2.5 years – through two winters and three summers. The Room was designed with my retirement needs in mind and has proved to be the perfect solution. The G Room was built in just 4 weeks, with me and my two greyhounds installed in six. Builders Lee and Steve were amazing. Martin Lawson was the classic ‘can-do’ overseer and the Office staff wonderfully friendly, efficient, and supportive in every aspect of the project. We have remained close friends!”
