Specification & Pricing

No two gardens are the same and neither are our buildings – there is always something that makes them unique as we design them to suit each space. Whether you need a triangular office, a room under existing raised decking or other unusual requirement, we can deliver what you require. Thinking outside the box is one of our specialities.


Foundations

We use our own DGO designed PileBar© foundations. This means we use minimal concrete which is quick and also good for the environment. It also means we can easily cope with sloping sites. Often we can include initial landscaping and site clearing as part of our quotation and often dispose of tired looking sheds...

Timber frame

We use a timber stud method to construct our buildings and all work is on-site. The floor uses 150x50mm treated timber, the walls 90x40mm and the roof timbers vary depending upon the size but is never less than 125x50mm. A waterproof breather membrane is used to stop condensation build up in the walls and make sure the weather is kept out.


Insulation

Dore Garden Offices are not afraid of shouting about what we hide in our walls, floor and roofs as we use exactly what you need to make your room warm in the winter and cool in the summer.

80mm rigid dense insulation under the floor, in the walls and in the ceiling and then we use insulated plasterboard on the ceiling to help stop the loss of heat upward. Installed expertly, it leaves your room dry, cheap to heat and draught free.

Cladding

In an increasingly flooded market, we are unusual in using a 200mm x 20mm pressure treated softwood as standard. Laid horizontally and overlapped, it has a soft rustic appearance that easily blends in to the garden. It is also a cost effective solution which will last for 20 years with minimal maintenance.

We do supply other options such as Western Red Cedar and Siberian or UK Larch for a contemporary feel. All these are an engineered smooth tongue and groove with a hidden fixing system so you don’t see any nails.


Roof

Our gently sloping roof design is finished in 18mm external OSB board and then covered in a single piece of 1.1mm EPDM rubber. This great material lasts for 20 years, needs no maintenance and is enviro-ready meaning we can lay a green roof on top of it. If you are worried about running down the garden with your laptop or cup of tea in the rain, you may also want to chose one of our canopy or porch options to shelter under while you open the door.

Doors & Windows

Predominantly we install Anthracite Grey UPVC but can install any colour to match a house or preference. We also use timber doors and engineered oak Bi-fold doors which come with a range of finishes. For the complete inside/out garden experience, bi-fold doors are a must and can be installed in engineered Oak or Aluminium. Whatever you opt for, security and heat retention are always the priority.


Electrics

Just as with our wall finish, our electrics have the feel of a cosy home. 3 double sockets are fitted as standard with all the cabling in the walls. A central 3 spotlight light fitting and light switch is included in our standard price but LED downlights are another option. We undertake all the work and connect the room to your supply as required. Part P certificate can be supplied.

Internal Finish

We believe that when you walk into one of our buildings, it’s as if it was another room in your house – this means that it's fully plastered and doesn’t feel like a porta-cabin or pimped shed with badly joined panels, cover strips and gaps around the ceiling. The walls look and feel solid, clean and warm and can be painted whatever colour you require if desired. As standard we install 8mm laminate flooring with a medium colour wood grain – this means you can walk in a bit of garden before it looks dirty. Primed MDF skirting helps give the room its clean modern feel.
