I'm planning to build a garden shed / playhouse in my back garden. It will be 3.6 meters by 2.4 meters by 2.4 Meters (WxDxH)
It will not be visible from road and will not cast a shadow over any part of my neighbour's property. It will be constructed of timber and roofing felt, with exterior grade acrylic for the windows.
Will I need planning pemission?
