"My garden and my rules" is unfortunately not exactly the way it works with setting up a summer house or any other building in your garden. Whether you need to apply for a planning permit or not depends on the size and height of the building, ways of use, location in the garden and other details. There are two separate issues when considering a new garden building - Building Regulations and Planning Permission. In most cases, if the building has an internal floor space up to 15m² and its overall height is less than 2.5m, it is very unlikely that you'll need any Building Regulations or Planning Permissions at all. Even if your garden building is within the limits, it is still wise to contact your local planning office and get all the answers to your questions. drewniany domek ogrodowy
