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!
