What sits beneath the finish

How we build insulated garden rooms that last.

A garden room has to do more than look good on handover day. The structure, weather protection, insulation and ventilation strategy are considered as one envelope — engineered so your garden room performs year-round across the Midlands climate.

Every Roomrise garden room uses a precision-cut timber frame with 100mm PIR insulation in the walls, floor, and roof. Combined with residential-grade double glazing and a ventilated cavity behind the cladding, the result is a building that exceeds domestic thermal standards. That means lower running costs and a space that feels like a natural extension of your home.

Common Questions

Garden room questions answered.

How much does a garden room cost?
Prices typically range from £15,000 for a compact office pod up to £50,000+ for larger, multi-room structures. The final cost depends on size, design complexity, site preparation, insulation specifications, and high-end finishes like premium timber cladding or aluminum bi-fold doors. We provide detailed, fixed-price proposals after our design consultation.
Do I need planning permission for a garden room?
Most garden rooms fall under Permitted Development, meaning they do not require planning permission. This is generally true if the room is single-story, has a maximum eaves height of 2.5m, does not exceed a total height of 2.5m if positioned within 2m of a boundary, and takes up less than 50% of your garden space. We always assess these criteria during our consultation.
Can I sleep in a garden room?
Occasional use (like a guest bedroom) is typically fine, but if you intend to use the garden room as primary, permanent sleeping accommodation, it must comply with Building Regulations and will require planning permission. We can help you navigate this process if that is your goal.
Does a garden room add value to my property?
Yes, garden rooms can add significant value—often between 5% and 15% of the property's overall worth—by adding high-quality, flexible floor space. They are particularly attractive to modern buyers looking for fully insulated home offices or fitness studios without the disruption of a loft conversion or house extension.
Can a garden room have a toilet or shower?
Absolutely. We can design and install internal partitions to accommodate a toilet, shower, or small washroom. This requires connection to your mains water supply and waste system (often via a pump or gravity connection to the main house drains), and must comply with Building Regulations.
Can it have a kitchen or kitchenette?
Yes, we can build custom garden rooms that include kitchenettes, sinks, and breakfast bars. If you are adding a fully functioning kitchen for independent living, you will need to apply for planning permission and ensure full Building Regulations compliance.
