The general rule states that any freestanding building under 25 sq m and any house extension under40sq m to the side or rear of your house doesn’t require planning permission. But since the local rules might slightly differ we highly recommend customers check with their local authorities prior to purchase.For larger log cabins planning permission is necessary. Please keep in mind that LoghouseMasters only provides the log cabin you requested and is not responsible for planning permission, which is the customer’s responsibility.Knowing whether planning permission for your log cabin build is required when choosing is very important and will vary depending on your situation.
