It is necessary to provide for both the possible replenishment of the family and the personal characteristics of family members, their hobby. For example, a special room for a workshop or SMS newsletter service may be required. In general, the minimum number of rooms — 3. The kitchen can be either separate from the dining room, and make a single whole with it. In the second case, the minimum area can be considered 9 square meters. But even with such an area in the kitchen, it is quite difficult to install many household appliances: a dishwasher, a large refrigerator, as well as kitchen furniture — a large table with chairs and a headset. 15 square meters-the most suitable area that allows you to place all the necessary items in the kitchen-dining room. The living room is often the venue for lush family holidays. Therefore, its optimal area is 25 square meters. By the way, when planning the premises, it is necessary to take into account the level of natural light.
