The Granny Annexe

Also referred to as a Garden Annexe, this unique structure offers a wealth of benefits.

Essentially, a Granny Annexe serves as a fully self-contained residence, with the flexibility to be constructed independently from the main house or connected within the property. Its primary purpose often revolves around providing a comfortable living space for aging parents who require daily care, fostering proximity to their family for both convenience and security.

Beyond elder care, various family circumstances and needs determine the versatile uses of an annexe. This adaptable space accommodates the ever-evolving dynamics of family life, catering to changing living requirements each year. Typically, an annexe becomes a haven for teenagers or young adults in their early twenties, offering the desired freedom, space, and privacy, especially for those facing challenges in entering the housing market.

In essence, the allure of a Granny or Garden Annexe lies in its ability to provide ultimate separation, tranquility, and privacy for all members of the household while maintaining a strong connection to the heart of the main home.

Do I have to pay Council Tax on a Granny Annexe?

Dependent Occupancy in Granny Annexe: If a granny annexe is inhabited by a dependent relative, such as an elderly parent or a disabled family member, and is an integral part of the same property, it might qualify for an exemption from council tax. However, specific criteria must be met to satisfy the conditions for this exemption.

Fully Self-Contained Annexe: To be eligible for exemption, the annexe must be entirely self-contained, featuring its own entrance, bathroom, kitchen facilities, and maintaining separation from the main dwelling. Local authorities will thoroughly assess the level of self-containment to determine eligibility for the exemption.

No Renting or Subletting Allowed: To maintain eligibility for council tax exemption, the annexe must not be rented out or used as a separate dwelling. Engaging in renting or subletting activities could potentially disqualify it from the exemption.

Do I need planning permission for a Granny Annexe?

Before proceeding with your annexe project, it is important to ascertain whether planning permission is necessary, particularly if the structure is intended for permanent habitation.  A Granny Annexe that is inhabited on a daily basis will need planning permission or a Certificate of Lawfulness from your Local Planning Authority. 

Have you considered the Caravan Act?  Swift Unlimited strongly advises against utilizing it as a substitute for obtaining full planning permission.  Your peace of mind (and that of a loved one) is far too important to take such a big risk.

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.

An annexe can potentially add significant value to a property by providing additional living space and flexibility. The increased demand for multi-generational living arrangements and versatile living spaces makes annexes an attractive feature for potential buyers, contributing to the overall value of the property.

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.
