Do I need planning permission for my new garden room?

We aim to make the process of buying a new garden room as easy as possible, so the majority of our garden rooms are designed to be installed without planning permission, without compromising on your needs or wants. Our 20 years experience building garden rooms means if you do need support on planning, we're here to help.

Make the first step towards to garden room of your dreams, TODAY!

Whether you need extra space for your ever-expanding family, a quiet space to work from or a place to enjoy your favourite hobby, our fully insulated garden rooms are custom designed and can be up and running in a matter of days

Every component we use in our Cabin Master garden rooms is guaranteed for quality and durability. Each building comes with a 10-year workmanship and labour guarantee, plus the guarantees of each individual component or building material included. Below are some typical examples:

  • 10 year  guarantee on building materials.
  • 1 year  metalwork guarantee (including hinges, handles and ironmongery).
  • 10 year  guarantee on UPVc doors.
  • 10 year  guarantee on window frames.
  • 4 year  guarantee on glass window units.

We only use FSC produced Western Red Cedar or slow grown PEFC/FSC Scandinavian Redwood exterior cladding over BBA certified breathable membrane to ensure all our buildings meet our strict quality control standards. The walls are constructed from structural (C16) timber and are fully insulated with KingspanTM thermal insulation boards (or similar).

The interior walls are lined with FSC NeatmatchTM Moisture Resistant MDF interior wall board ready for decoration and our roof system is finished with Firestone EPDM single piece rubber membrane roof covering complete with purpose made verges and gutter trims finished in black. Black uPVC guttering and downpipes are provided as required.

Our design team are on hand to turn your vision into a reality. Your ideas and sketches are transformed into a CAD drawing which is then perfected until you are 100% happy. The design is then sent to our factory where the cabin is created.

When you order your new garden room, we will arrange a convenient delivery and installation schedule, with an affordable quote tailored to your needs. The cost of delivery and fitting depends on the size of your building, where you live, transportation distance and how many people you need to set up your garden room.

The final price is determined by the size of your garden room and the features you choose. We provide a comprehensive, transparent quote for each garden room, issued on an individual basis. Your quote will include design consultation, base, construction materials and labour.
