    Garden Offices Energy Saving Insulation
    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 the roof, 0.62 W/m2 K in walls, and 0.70 W/m2 K in the floor.*Insulation means a reduction in loss of heat from an area that has been heated to a different temperature. If no heat has been applied, the insulation will be nominally the same as the outside temperature.

    Garden Offices EPDM Roofing
    Garden Offices EPDM Roofing II
    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

Average Seller Rating:

We wanted a working space at the top of our uphill garden which would command the magnificent view that we do not get from the house. The Lienne MKIII has proved exactly right in terms both of internal space and of openness to the outside world. It also sits well in its natural surroundings: good clean modernist lines without making a brash statement. It is thoroughly well-designed, uses high-quality materials (excellent insulation, and a really thick roofing membrane, for instance), and gives a real sense of solidity. I would say that this is an excellent product. I decided to assemble it myself (I should perhaps mention that I am a complete and ageing amateur), and this has given me particular insight into its construction, which has been very carefully thought out. Apart from the help of two strong men for the really heavy work of putting the wall-panels together (and the services of a professional plasterer and electrician), I completed the whole project virtually single-handed. For the sake of complete transparency, I should mention that I encountered a few small issues along the line: minor deficiencies and inconsistencies in the instruction manual, and a wrongly supplied part, but I was in the end able to overcome the former, and the latter was resolved by the company to my satisfaction. These are insignificant incidents in the context of the whole project, which I have enjoyed, and the results of which give us all great pleasure.

So far so good am just finishing the outside area around the garden office which was assembled by a very useful and efficient team during a week of quite awful weather. My daughter will be the first to use the building. I did not opt for downlighters but have instead fixed LED spotlights on a bar and am installing an infra red heater energy efficient, healthy and much cheaper after an intial layout. I am pleased with the process so far and will be interested to see how it works out. It would be useful to know the appropriate wood stain to use to match decking to the building, I have opted for Sadolin Light Oak and hope it will match but its too cold to put it on! I will send pictures when its finished if you remind me. Pleased so far.

Thank you so much for your review! We are pleased you like it so much. Your comments seem to indicate you like it all a lot more than the 3 out of 5 stars you've given it! Perhaps after it is all finished, you might come back and leave a 5 star review!

I work from home and we needed some extra space, so ordered the Lienne garden office. The 3.9x2.7 size is a great size for me, and fits desk, filing cabinet, bookshelves and visitors chair. The office is really light and lovely to work in - it warms up fast with an electric heater and really holds the heat as well. I would certainly recommend this to anyone who needs some extra space. The Dunster staff who came and installed it were very efficient too.
