A vacant, worn office space should be transformed into a show apartment / showroom. The existing space had been used as an office structure since the 1960s. Located on the 4th floor of a ten-floor reinforced concrete skeleton, the area is already high enough to receive a great amount of light, which is particularly noticeable at dawn and dusk: sunrises and sunsets conjure up the most spellbinding blends of light. The existing structure and also the technical equipment were completely outdated and needed to be completely rebuilt: suspended ceilings were removed and walls changed. The result is a modern city apartment of almost 100 m2 (about 1,070 sqft) – divided into a large living space, 2 rooms, 1 bathroom, 1 powder room and 1 utility room. The existing window facades could not be changed, but they are part of the concept anyway, namely to bring as much light as possible into the room. A controlled ventilation system ensures optimal air quality even with closed windows. The central kitchen element serves as a kind of separation of the living area and the dining area. Here customers and guests are served, people communicate, cook together, drink a glass of wine. Clients experience living. The rough reinforced concrete ribbed slaps were uncovered and painted white to give the room more height, which is accentuated by the lighting concept with ceiling-mounted spotlights. The dark oak floor creates a successful contrast to the brightly designed rooms. The wittily positioned pedestal areas hide all technical elements, such as the supply air openings of the living room ventilation. Flush-fitting door elements in the walls with a chalked brick look show in detail the special feature of the room. The central wall elements were deliberately not pulled up to the ceiling, but are separated by a glass element to show the continuity of the construction. Most of the furniture was designed by Wolfgang Pichler. Within the course of this project he was able to implement his holistic approach in the field of construction technology, architecture and furniture design and skillfully combine it with design classics. Scandinavian classics can be found in the concept just as much as pieces he collected during his career and furniture he developed for the company VITEO, which he founded in 2002. The project illustrates the added value of an architectural holistic approach.
