A granny annexe is a self-contained living space designed to provide comfortable accommodation for a family member, usually within the grounds of the main home. Thoughtfully designed and beautifully finished, it can include everything needed for day-to-day living, such as a bedroom, bathroom, kitchen area and living space.
For many families, a granny annexe offers the perfect balance between independence and closeness. It creates a private place to live, while allowing loved ones to remain nearby and connected to family life. As part of our wider annexe range, each design can be tailored around the way your family wants to live.
Included features may include:
Bedroom and living space
Bathroom or shower room
Kitchenette or kitchen
Designed for year-round comfort
Tailored to your property and requirements
A well-designed granny annexe should feel every bit as welcoming, practical and comfortable as the main home. Our bespoke designs are created around real day-to-day living, with carefully considered layouts, quality finishes and a strong focus on comfort, privacy and ease of use.
Whether you are looking for a compact annexe for one person or a more spacious layout, we can create a design that reflects the needs of your family and your property.
Flexible Layouts
Choose from open-plan spaces or more defined room layouts, designed around one or two occupants.
Designed for Everyday Living
Incorporate kitchens, bathrooms and living areas that feel elegant, practical and easy to use.
Private Space, Close to Family
Keep a loved one close, while still creating a space that offers independence and a genuine sense of home.
Where needed, layouts can also be shaped around future practicality, accessibility and comfortable long-term living.
For many households, a granny annexe is a thoughtful and practical way to bring family closer together without compromising on privacy or independence. It can provide a beautiful living solution for an elderly relative, a dependent family member, or wider multi-generational living, all while making better use of the space you already have.
Choosing a granny annexe can also be an appealing alternative to moving house or making major changes to the main property, offering greater flexibility both now and in the future.
 Key advantages: Â
Keep loved ones close to home
Create a private, self-contained living space
Support multi-generational family living
Make better use of your property
Enjoy a flexible solution for changing family needs
Planning Permission
Because granny annexes are designed as self-contained residential accommodation, planning permission will usually be required. The exact requirements can vary depending on the site, the scale of the building and how the space is intended to be used. You can read more on our planning permission page.
Council Tax
Annexes are often assessed separately for Council Tax, although discounts or exemptions may apply depending on the circumstances. In some cases, a 50% discount may be available, while in others a full exemption may apply where a dependent relative lives in the annexe as their main home. As this can vary depending on the living arrangement, it is always worth checking the latest rules with your local authority.
We can help you think through these practical considerations at an early stage, so the design is aligned with both your goals and the intended use of the annexe.
At Heritage Living, we create beautifully designed annexes that are tailored around the way people truly live. Rather than offering a one-size-fits-all solution, we work with you to create a bespoke annexe that complements your property and provides the right balance of comfort, practicality and style.
Using SIPs construction, we create spaces that are warm, energy efficient and suitable for comfortable year-round living, while still allowing flexibility in layout, finish and overall design. You can also browse our case studies to see more of our completed projects.
