High-tech is an architectural approach that is adequate to urban planning and public interiors rather than to private residential space. This is an ambivalent style that has grown out of admiration for technical progress and at the same time realizing the threats and dangers hidden in it. Using it in a residential interior requires special sensitivity from the architect, he has to adapt hard, sometimes aggressive forms to everyday life. The size of the apartment and the height of the ceilings in the new house dictated an ultra-modern architectural solution. The central composite element here is a high notched stained glass window, from floor to ceiling. The main stylistic device is a well-balanced combination of space and light: hard broken forms, glass and nickel-plated surfaces, in which natural light is reflected and refracted, penetrating into an apartment through a stained-glass window. In the penthouse with a height of almost seven meters, it was decided to make the second level. And at the same time, to find such a space-planning solution, in which the most interesting element in space will not be harmed - a complex window with a panoramic view of the city. The balcony encircling the apartment around the perimeter, not only was a beautiful compromise way out of an architecturally complex situation, but also gave the author of the interior additional expressive means. A broken glass staircase is an expressive accent that forms a pair of stained glass teeth. Metal railing fences, frosted glass, furniture MOBILEFFE and metal kitchen parts BOFFI and GAGGENAU techniques form a uniform, stylistically aligned space. Thus, the living room, dining room and kitchen on the first floor stand out in the front area, it demonstrates the main techniques that make up the overall design solution of the apartment. The second floor with an office and a small living room is similar to the mezzanine, from which it is supposed to watch the technoshow unfolding below. The private zone (master bedroom, children's room, dressing rooms) is much more moderate, here the form is strictly subordinated to the function of the rooms. It is united with the front part of the apartment through neutral elements: such as "sailing" lamps, which on the second floor emphasize the arched shape of the ceiling. Abstract painting from the collection of the apartment owner also compositionally combines different parts of the interior. The overall color solution (white, shades of blue and achromatic tones), a large amount of natural light create a wonderful background for the canvases. Adjacent to the bedroom, a bathroom with a glass podium and wooden sanitary ware is a game element in the space of the apartment. This hidden from outsiders zone, intended only for owners, as if quotes the front door: here is the same frosted glass, a miniature staircase with a break, a tall window. Herbal use of materials (the podium is made of glass, the bathroom is of dark wood) muffles hard forms and brings a soft ironic element into the interior. White pebbles laid out on the perimeter of the bathroom at the same time emphasizes and softens the laconic nature of the environment, expanding the eternal theme of natural and man-made martial arts. Metal, wood, glass, stone - the attributes of the latest architectural and interior fashion. Masterfully using them in a residential interior, the architect was able to observe the necessary balance of conceptual and functional, to create an expressive, tense and at the same time comfortable space.Alexey Borisov: “Metal, steel and glass are not like my favorite materials ... Rather, I wonder how they“ work ”with each other, what possibilities this combination opens up to create a comfortable living space. With customers of the penthouse I designed, It was easy and interesting to work, because my ideas are close to them - at the decoration stage the hostess was practically my co-author. "
