Why Choose a Garden Room in Wiltshire?

A garden room is one of the most efficient ways to add usable space to your home without the cost, disruption, or planning complexity of a traditional extension.

Our Wiltshire clients typically use their garden rooms and garden offices for:

  • Home offices

  • Garden studios

  • Home gyms

  • Treatment rooms

  • Multi-use family spaces

All of our cabins are built using fully insulated SIPs construction, meaning they perform like a proper room, not a seasonal structure.

Planning Permission in Wiltshire

One of the biggest advantages of a Backyard Cabin is that most builds fall under permitted development.

Our cabins are designed under 2.5m in height, meaning they typically do not require planning permission.

For homes in conservation areas or the North Wessex Downs AONB, we can provide guidance to ensure your garden room complies with local requirements.

Built for Year-Round Use

Every Backyard Cabin is designed for comfort in every season.

  • Fully insulated walls, floor, and roof

  • Double-glazed doors and windows

  • Thermowood or high-quality timber cladding

  • Durable EPDM roofing system

  • Clean, plastered internal finish ready to use

This ensures your garden room stays warm in winter and comfortable in summer.

A Simple, Professional Installation Process

We keep your garden room project straightforward from start to finish.

  1. Choose your cabin model or discuss a bespoke design

  2. Prepare the base (we can advise on this)

  3. We install your cabin on-site

  4. Your electrician connects power from your main property

Most installations are completed in around 2–3 weeks.
