Depending on what type the cottage will be necessary to decide on the laying of the foundation. It can be slab, columnar or strip.
It is also very important that the construction of the roof and the structure of the ceilings are also. For the construction of the roof, you can also choose the material: bitumen or soft tile. I use soft tiles more widely. You can also use metal tiles. So, after choosing a project and materials, you can safely start building a cottage.
