"We did a water supply straight off the washroom on our house into the studio and the waste is straight into a drain although we do have a filter before the drain which was advised when cleaning pets.
I did a fair bit of research into having a shop or premises and my QCB garden studio will be paid for in 2 years when compared to renting premises.
My only overheads are the gas which I use for the dog's hot water and I run a little oil heater set on it's minimum. That keeps it lovely and warm but once I'm in there working I don't even need that during this cold January."
