Garden Room & Office are based in the UK but the actual kits are sourced from Bulgaria, and the company can supply their kits throughout the UK and Europe.

It seems a very simple proposition, the company supplies garden office kits in two external finishes Spruce and Cedar and each finish in two sizes 3m x 2m x 2.3m high and 3m x 3m x 2.3m high. The Spruce option is cheaper than the Cedar version and although the Spruce has been pressure treated it will require a decorative finish applying and on going maintenance, the Cedar on the other hand can be left to weather to a silver grey as it has natural preservative qualities.
