Granny Annexes for Elderly Relatives

Granny Annexes for Elderly Relatives

granny annexe

Granny annexes can be a great solution to allow our elderly parents to live independently, for longer, in a place they can call home. In a perfect world, our parents and grandparents would be able to stay living at home, independently and safely, for much longer than their health might allow. However, there are approximately 418,000 people living in care homes in the UK, despite many of these people not needing extensive care at all – for example if they have had to move when their spouse has needed further care or has died. 

Domiciliary, or Live-in care does allow for people to live in their own home for longer, but at some cost – the average yearly cost of live-in care is approximately £40,000. In all care options, there is also an aspect of outsourcing your parents care to strangers. While there are thousands of great carers throughout the UK, for lots of people they would prefer to provide the minimal care their parent’s need themselves.

“We all want to live in the place we call home, with the people and things we love, in communities where we look out for one another, doing things that matter to us”

Social Care Future

About Kāinga

kainga care granny annexe optionsKāinga was founded by Jeremy Jayasuriya BA (Hons) Social Work who believed there had to be an alternative solution to care homes and live-in care that was affordable and allowed older people to live independently while allowing families to be fully reassured to their safety and wellbeing.

What is a Granny Annexe?

A Granny Annexe, or Garden Annexe, is a way for elderly parents and grandparents to live with, or very near, to their families. Rest assured, Granny Annexes are also a great option for Grandads! Garden Annexes for elderly people mean that families can feel completely reassured to their wellbeing, while allowing them to live completely independent lives. Unlike with some care options, Granny Annexes allow older people:

  • to live in a place they can call home
  • to settle into a community
  • to live the life they want to live safely and independently
  • to be cared for by the people they love
  • to save the money from selling their house

How much do Granny Annexes Cost?

The idea of including a Granny Annexe in your care solution seems like it would be an expensive one, however, compared to the costs of full time care at home, or in a care home, some granny annexe prices can be much less. In England, the average the cost of a care home is £44,000/year, which will vary greatly depending on where you live. Live-in care is likely going to cost around the same. When it comes to the cost of building a granny annexe:

Type of Annexe

Price of Annexe

Full extension connected to house
from £75,000
Permanent Outhouse
from £50,000
Kāinga temporary annexe
from £350 per week

Kāinga Care Granny Annexes

As part of the care solution the Kāinga Care Annexe is designed carefully to meet the needs of the elderly person making sure you are comfortable, safe and feel at home.

Each annexe has been constructed to BS3632 standard (a ruling for park homes and lodges) so you can be assured of the quality of the garden annexe. Fixtures and fittings are robust, tasteful and user friendly given possible limitations in mobility, strength or any other concerns.

Because the annexe is a component of the care solution it is temporary and will be removed when it is no longer needed. It is charged on a weekly basis at a cost affordable to many from £350 per week depending on the style and adaptations you would like. We believe this makes it the cheapest way to have a granny annexe in the UK.

  • Designing a warm, comfortable living space in the Annexe for the loved one; connected to all services. Depending on space available and your preferences the annexe can range in size from 14.5 sqm to 38.5sqm
  • Offering Carbon-Zero solutions where possible. All annexes are designed to minimize their impact on the climate and we will work with you to create as close to a Carbon Zero solution as we can
  • Offering smart technology which will include fall monitors, health monitors, medication alarms, and home security and monitoring systems. There are also communication and GPS systems that can be found if there are worries about this aspect of safety

How long does it take to build a granny annexe from Kāinga?

From start to finish, granny annexes are likely to take at least 5-6 months to build when you factor in planning permission and other variables. While with a Kāinga granny annexe, you will probably still need to get planning permission, as a simple, external building this is likely to be a lot quicker. The other benefit is that Kāinga don’t have to wait for planning permission to get started. While planning permission is being approved, Kāinga can get on with putting together the annexe off-site, which saves a lot of time. Usually, from order to installation, Kāinga estimates it will only take 3 months to get a well-built, comfortable, granny annexe in your garden.
