Hello there, we live in a very rural area and have a 1 acre garden and 3 acres of farmland with our cottage. I would like to build a large garage/workshop in our garden in the coming future to house my vintage tractor, 2 old land rovers and a workshop/garage. It would be L shaped and the size would be: 40ft on the long side and 35ft on the other with a width of 15ft ie works out at 86 square meters. Would have a pitched roof under 4 meters, be over 5 meters from the house. We have just had an extention done to the cottage and with the new garage we would still not have covered half of the garden by a long way with buildings. I know building regs will apply but do we need planning for this?
