Garden annex

Garden annex — self-contained living

A fully self-contained modular home in your garden — private kitchen, bathroom, heating. No foundations, no planning permission in many cases. Delivered ready.

A self-contained home in your garden

A Quintillio garden annex is a fully self-contained modular home placed in your garden — complete with private kitchen, bathroom, heating and all services. No foundations needed, no permanent alterations to your property.

Our homes sit on a galvanised steel chassis with wheels, classifying them as caravans under the Caravan Sites Act 1968. This means many garden annexe installations don't need planning permission — though requirements vary by local authority.

Whether it's for elderly parents, adult children, a home office, or rental income from an Airbnb let — a Quintillio garden annexe adds immediate living space without the cost and disruption of a traditional extension.
