The main aim of reconstruction is to make big open concept of modern flat with functional space. Dinning area is moved on entrance because it can be pass-throw. Kitchen is moved on the wall were is entrance. It is big and functional. It has big kitchen island where can be move water from the wall if you want. In other case it can be for breakfast and seating. The largest place is for living room. It has big seating furniture with open concept and can be made with interesting modern lights. Corridor is only one because it can be only for pass. In place where was kitchen and two bathrooms now is made master bedroom with master bathroom and big walk in-closet. From corridor you can walk in laundry area where can be two laundry machines and shelves for laundry. In other site of corridor are two single bedrooms with walk in-closet and there is also bathroom for than two single rooms. Where was master bedroom now is placed library with office space where you can read books or take a rest. All entrance walls which can be moved are reconstructed. I hope you like my idea because it's functional and with modern concept.
