What makes us unique...

There’s a lot of choice when it comes to picking a garden room company, but there’s only one company that does things like us...

  • Dedicated point of contact

    We keep things simple by assigning you a dedicated team member to manage your build and answer any queries.

  • Eco-Friendly Company

    Carbon neutral, landfill-free and solar powered – just some of the steps we take to care for the environment.

  • No Hidden Costs

    Our pricing is transparent with all ‘essentials’ included in the price of your building to make things simple and hassle-free.

  • Backed by Kevin Mcloud

    The architectural guru and environmentalist has given us his seal of approval, impressed by our eco credentials.

  • Add value to your property

    Prices for garden buildings start surprisingly low for smaller garden offices. Even grander designs are much cheaper than the equivalent extension and so much easier to plan.

FAQs

  • Can I have any size I want?
    Most buildings can be adjusted in 50cm / 60cm increments with the exception of the Linea which can be made to whatever size you please!
  • Are the buildings customisable?
    Our buildings are fully customisable to suit your space! Select from a wide range of doors, windows, sizes & colours to create a truly unique building.
  • Do the buildings need planning permission?
    All of our flat roof buildings are made to 2.5m high to comply with permitted development rights. If you reside in an area of outstanding natural beauty or live in a listed development you will need to seek advice from your local planning office.
  • Do you have Bi-fold doors?
    No. All of our doors are timber and the natural movement of timber throughout the year causes frequent complications with bi-fold and sliding doors.
  • How small can you make a garden building?
    We can make a garden office/studio as small as 1.8m x 1.8m!
