The theme of the project is to design new buildings, an ambassador residential villa. The aims of the project are to elaborate architectural design documentation for landuse proceedings, the project for building permission and related matters. The building is situated on two parcels in the King Valley in Bratislava in a very lucrative location matching for this purpose. We comforted the design of the building orientation to the cardinal direction with respect to current ecological trends in architecture. The building of residential villa is based on conventional strip footings. There is a wall support system, in the underground floor there is an external wall build of the mould shaped bricks 300 mm thick, bricks Heluz Thermo STI 44, eventually equivalent masonry of the same thickness and similar attributes are used in the upper floors. Ceiling structures consist of reinforced concrete monolithic plates and corrugated ceiling. The building covers the flat roof with three different structures- a trafficable roof, an intensive green trafficable roof and extensive green non-trafficable roof. There are wooden windows and doors with exterior aluminium surface treatment; glass walls consist of aluminium frames and double- insulating glass. Wooden wall facing and Rheinzink wall facing are used on the facade. The building layout is divided into two main operations - private and social part. Each of them has its own main entrance and also a side and supply entrance. For the purpose of parking is set up 5 parking places, two in the garage and three in the reserved area in front of the villa. The private part of the building intended for ambassador's accommodation has three floors, the first floor is dominated by an interconnected living room, kitchen and dining room and a garage, bedrooms and hygiene are mostly on the second floor, in the basement you will find fitness, wine-cellar and HVAC areas. The entire social section, accessible to persons with wheelchair disabilities, covers the first floor; its main parts are the hall, lounge, dining room and food preparation.
