I work from the office most days when I'm in country - its a two room shed with a bar in the other room. The office has two computers in plus a printer and a full offcie set up with storage cupboards and filing cabintes all in matching white. The Bar is a fully stocked bar with 25+ types of gin, 5 types of Whisky and 7 different vodkas. A fully stocked triple beer fridge, with wine and soft drinks and in ice machine. We have a 65" 4K TV with Bose surround sound and additional disco speakers for entertainment with both Sky and BT plus the sound system can link to a phone to create a disco. The bar has disco lights underneat. We have underfloor heating across both rooms (seperate), extra thick insulated plaster board interior for walls for both warmth in winter and cool in summer. One wall is made of welsh slate (behind the bar - which is mirrored) all others are plasterboard and painted. It really is a must see bar.
It was built to my specification out of breeze block and wood cladding. it has a veranda area in front to relax in summer and smoke in evening (i am not a smoker) and triple bi-fold doors for access with two huge windows each side for light in the office and behind the bar. it has a felt flat roof and external power sockets.
the bar is regularly used to invite friends and family around for football games, boxing rugby etc or just a great night out. the lights can give a disco effect too and we have held dinner parties in the shed too. It is the focal point of our garden.
