A summer cottage build independently in a garden like a  “hut” can be a fun and interesting DIY project. It can be used for different gardening needs or for personal relaxation. You can make a cozy toilet, bathroom with a shower or technical auxiliary room, where you can store small gardening tools. If you make it large enough 3 x 3m, 4 x 5m  its sure that something good will come out from the design that can also have a small kitchen. Build a “hut”can be alone shelter for a few days or a weekend.  The foundation for such a construction can be made of blocks with a step through 1-1,5 m setting them on a sandy base 20-30cm. The main frame can be made of timber 100 x 100 or 100 x 150 mm. Piping should be processed with antiseptic!
