To achieve this base you will need to dig out 25-30 cm ground, fill it with gravel and then a good layer of sand to provide a level surface. Then, finally lay down the concrete slabs, blocks or similar. It is vital that your base is level as your cabin will only be as level as your base!The most popular, but more expensive and durable foundation type is a concrete base. A concrete base is a perfect fit for all types of garden buildings.
