Garden Annexes for Multigenerational Living

Independent homes for ageing parents

With UK property prices at record highs and care home costs rising, many families are thinking about how elderly loved ones can be cared for at home. One of the most popular solutions is the garden annexe – a self-contained living space built in the garden, offering independence for your parents while keeping them close. 

In this guide, we’ll explore why garden annexes are becoming increasingly popular, what they cost, how planning permission works and the latest design trends.

Why Garden Annexes Are Growing in Popularity

Families today face unique challenges:

Elderly parents needing support, but valuing independence.

Adult children returning home due to high housing costs.

Live-in carers requiring private accommodation.

A garden annexe balances privacy and proximity, giving everyone the space they need while keeping family support nearby.

Privacy with Peace of Mind

For elderly parents, independence is crucial – but so is safety. A garden annexe with a bedroom, bathroom and kitchenette allows your parents to live privately while being just a few steps away if help is needed.

This works for everyone: knowing loved ones are close without sharing the same roof.

Accessibility and Comfort

Modern annexes are designed with accessibility in mind:

Step-free entrances and wide doors for mobility aids.

Non-slip flooring and grab rails in bathrooms.

Heating, insulation, and proper lighting for comfort year-round.

These features make garden annexes suitable for long-term independent living.

Cost Savings vs. Alternatives

Care homes can cost £35,000–£50,000 per year per person. A garden annexe is a one-time investment (£30,000–£60,000+) that provides years of value and can increase property value by up to 20%.

Planning Permission and Legal Considerations

Garden annexes differ from standard garden rooms because they’re classed as habitable spaces. In most cases:

Planning permission is required if the annexe has sleeping, cooking or bathroom facilities. Building regulations also apply for an independent dwelling. Working with experienced suppliers ensures compliance and a painfree approval process.

Garden Annexe Design Trends 

Stylish exteriors: timber cladding and contemporary finishes.

Compact but smart layouts: one or two bedrooms, open-plan kitchens, space saving storage. 

Energy efficiency: Excellent ‘u’ values, good insulation, eco-friendly materials.

Flexible spaces: annexes that double as guest houses or rentals.
