    Avoid Planning Permission
    All our Garden Offices are under 2.5m high so that under permitted development rights you can place the building within 2m of a boundary if you wish to. Please be aware that any building over 2.5m high needs to be placed over 2m away from any boundary. If you want to find out more about planning permission click here.
  • 10 Year Guarantee
    All of the exterior timber of your Garden Office is pressure treated. We offer a genuine 10 year guarantee against rot and insect infestation on all of these parts. So you won't need to worry about little critters causing havoc or rot damaging the timber.
  • Energy saving insulation
    The walls, floor and roof of our garden offices are all insulated to lower energy costs. We use foil backed Polyurethane to insulate our garden offices, which is proven to retain heat better than cheaper alternatives such as polystyrene or rockwool. The U values of our insulation are as follows: 0.64 W/m2 K in roof, 0.62 W/m2 K in walls, and 0.70 W/m2 K in floor.
  • 28mm Double Glazing
    We don't compromise on quality just because it's a garden building. Our garden offices have domestic style uPVC windows and doors, making your garden office secure and highly insulated. The 28mm sealed double glazing provides improved heat and sound insulation.
  • Multipoint locking windows & doors
    Our garden offices come with domestic grade multipoint locking windows and doors. Great for securing your garden building and its contents! Euro cylinder locks are used in our uPVC doors to ensure maximum safety and security.
  • Smooth plasterboard interior
    The interior walls and ceiling of our garden offices are covered in uninterrupted plasterboard for a clean, sleek and professional look. Complete with coving and skirting boards you have a look that is the same as you would expect to find in a house.
  • Easy to build panel system
    Using a technique unique to Dunster House, we've been able to create panels that simply slot together, ensuring the rigidity and strength of this office surpasses many alternatives and is quick to build.
  • Halogen spotlights
    Recessed halogen spotlights are located around the office to provide plenty of light, controlled by a light switch just like they would be in your home!
  • Electrics Included
    Everything you need to run electrics within the Garden Office is included. We use our own qualified electricians to install and test the electrics if we are installing the building for you. The only thing we don't do is the connection between the Garden Office and your existing electrical supply.
    EPDM Roofing
    Our Garden Offices feature an EPDM covered roof. EPDM has been widely used in commercial and residential flat roof applications for over 30 years and has an enviable record for durability and waterproofing. We’re so confident in our choice of roof material that we give a 10 year guarantee against rain water penetrating it. Being made from one large sheet it also means that the roof won’t be covered in clout nails as is the case with felt roofing, but please be aware that there may be some bubbles trapped under the EPDM material when it is laid and/or creases. The pictures above show a typical EPDM roof installation on one of our offices
  • Free fixing pack
    We include all of the screws, nails and fixings needed to put your garden building together, not everyone is that thoughtful! So there's no need to worry about the type of screws, or length of nails etc you might need to get started, it's all there in the pack!
  • Fully pressure treated
    Our Garden Offices are made using non-toxic, pressure treated timber. This process forces wood preservative deep into the pre-cut timber using a large pressure treatment vat. This allows us to offer our customers a 10 year timber guarantee against rot and insect infestation.
