There exists a comprehensive range of garden office designs on the UK market today. From the lower price range bursts a variety of sheds with plastic window panes and pitched and flat roofed log cabins. For under £8000 it is possible to achieve a space to work in reasonable summer comfort. I like the colourfully painted sheds which sit very well into a cottage garden, highly planted with tall wallflowers, foxgloves, dalias and rambling roses. In this way, landscaping around your shed with appropriate plants allows it to really fit in.
Middle price range garden offices tend to be constructed with polystyrene insulation sheets and clad with horizontal shiplap board, stained to your colour preference. Windows may be PVC and double glazed for a little extra warmth in the autumn chill. Traditional pitched roofs are common with this design, as is the popular feather-edged cladding for under £15,000. This style holds its own in a rural setting and can be expanded into larger structures, suitable as farm shops or showrooms.
Upper range garden office designs are usually very contemporary. Cedar cladding with aluminium or chrome trims and sharp boxy lines emanating from almost-flat roofs send this set of designs into the £22,000 – £40,000 bracket. Some variation can be achieved with thermally broken aluminium glazing options and integral decks. Best structure for this money has got to be BBA approved SIPs panels with professionally pressed polyurethane insulation: rigorously tested for all year round comfort, cool summer working, warm winter comfort and the longest verifiable durability.
Glasshouses and oak framed buildings meet in this upper price range too and can easily exceed £40,000. The building technology for oak frames tend to be traditional with a lower thermal performance than the SIPs structure mentioned. The glasshouses need to be displaying very low u-values to be suitable as a working office.
In conclusion, one can achieve a garden office from £8,000 to £40,000 and the price increase usually reflects an increase in quality. Using this guide, you are justified in expecting certain quality standards for your money. A wary word on SIPs panels – many companies claim to use the latest but make them in a poor back-yard fashion using polystyrene and various glues. The result is an over priced product with shortened life and poorer insulation qualities. Ask for a garden studio independent thermal value calculation or certificate number.
