We are having a bespoke option built, 4m x 3m wooden, double skinned, insulated, UPVC double glazed anthracite colour specially glazed can’t remember the name but stops heat coming in or out, farrow & ball paint french grey, rubber roof, data points, electric sockets, outdoor power point. Concrete base. £14,000 all installed. We will use ours for treadmill & home office.
Really excited, concrete being poured into frame next week. Ready for install in May. We ordered in Feb, and that is quite a quick turnaround, we paid 50% upfront and Balance when we are happy with the install.
Thereis quite a delay, so if you have a need OP I would get one on order ASAP, as many companies we looked at weren’t available to deliver for 6mths.
We managed to find a local specialist that designs, builds & Installs. Which for us was a better & quicker option, and in fact cheaper that an off the peg internet purchase.
The quality we looked at in garden centres was very poor, windows & doors not closing properly poor quality timber, make sure you see what you are buying and if in the UK and you want to use it all year insulation will be required, it was cost a small fortune to heat otherwise.
