Unique & high-quality annexes.

Keep family close while giving everyone space of their own. At Wren Lodges & Garden Rooms, we design and manufacture bespoke garden annexes in Wales, with layouts tailored to your household, garden and day-to-day needs.

Based in St Clears, Carmarthenshire, we work with customers across West, South and Mid Wales. Whether you are considering a granny annexe for a parent, additional space for an adult family member or comfortable guest accommodation, we can discuss a design around your property and the permissions required for its intended use.

A Garden Annexe Designed Around Your Family

A well-planned annexe can bring relatives closer while preserving privacy and independence. The right layout makes room for everyday routines, from preparing breakfast and relaxing in the evening to welcoming visitors.

We can discuss a compact layout or a larger annexe with separate living and sleeping areas. Window positions, entrances and the relationship with your main house can all be considered as part of the design.

If accessibility is a priority, tell us about requirements such as step-free access, wider doorways or additional bathroom space at the outset, so these can be considered in the proposed layout.

Choose Your Layout, Features and Finish

Your annexe can be specified around the space available and how it will be used. Depending on the agreed design, options include:

• Separate bedrooms and living areas.
• A kitchen or kitchenette with storage and worktop space.
• A bathroom, shower room or en-suite.
• Insulated walls, floor and roof.
• Glazing, doors, heating and lighting selected for the intended use.
• A choice of external cladding, colours and internal finishes.

Comfort Throughout the Year

For an annexe intended for regular occupation, comfort needs to be considered throughout the building. Insulation, glazing, ventilation and suitable heating should work together, alongside a practical layout and the appropriate construction specification.

We discuss these details with you when developing your annexe, including how it will connect to electricity, water and drainage where required.

How Much Does a Granny Annexe Cost in Wales?

The cost depends on the building’s size, layout, specification and installation requirements. A fully fitted annexe with a kitchen and bathroom has different requirements from a garden office or hobby room.

Site access, foundations, ground levels, service connections and chosen finishes can also affect the overall budget. When requesting your quote, tell us your approximate dimensions, postcode, intended use and the facilities you need.

Ask for the quotation to identify what is included, any separate site or connection costs, and the applicable VAT, so you can assess the complete project.

Planning Permission and Residential Use

An annexe intended for living or sleeping needs careful consideration of its planning status. The position depends on the property, the proposed building and how it will be occupied. Confirm the requirements with your local planning authority before proceeding.

Building regulations are a separate consideration. The usual exemptions for small detached garden buildings exclude sleeping accommodation, so confirm the requirements for your particular proposal with building control.

You can read the Welsh Government’s guidance on planning permission for outbuildings and building regulations for outbuildings.
