A garden annexe, often called a granny annexe, is a self contained home in the garden with its own bedroom, bathroom and space for a kitchen. The PrefabX modular home annexe arrives finished and plumbed ready for a kitchen, unfolding in 2 to 3 days, giving a parent or adult child comfort and privacy close to home, from a fixed price of £25,000.
A garden annexe is right for you if
Bedroom, bathroom and living space fitted as standard, plumbed and wired ready for your kitchen, so it lives like a real home from day one.
The annexe arrives finished and unfolds in 2 to 3 days, so a relative can move in within weeks rather than waiting out a long build.
Insulated, heated by discreet skirting and built at ground level, it is comfortable and easy to live in at any age.
The range
The Studio is a complete compact annexe for one person, while the Annexe gives two bedrooms and a separate living space, in your choice of a separate or open plan kitchen, for a couple or longer stays.

Common questions
Often yes. A garden building used as independent living accommodation for a family member usually needs planning permission, even where a plain garden room would not, and may need to meet building regulations. We assess your site and use, and guide you through the application where it is required.
A self contained PrefabX annexe starts from £25,000 for the compact Studio and from £30,000 for the two bedroom Annexe, fully fitted and installed. That is a fixed all inclusive price covering the bathroom, heating and electrics, with the unit plumbed and wired ready for your kitchen.
Yes, a modular home annexe is built for full time living, with insulation, heating, a fitted bathroom and the plumbing and wiring ready for a kitchen. Permanent occupation by a family member is usually allowed with the right planning consent, which is the main thing to confirm before you order, and which we help with.
A self contained annexe adds usable living space and appeals to buyers who need multigenerational accommodation or rental potential, so it generally adds value. Because the modular home is a permanent, properly built home rather than a temporary cabin, it counts as genuine extra accommodation.
