Building permit project fills the last big empty plot on the entrance to Bratislava city district Jarovce. This plot used to be a collective farm. Nowadays, there are new existing family houses and apartment houses all around. We designed a new compact urban zone consisting of 9 apartment houses part and 24 family triple-houses. From the very beginning our intention was to create an urban structure in the scale of a village with all the advantages of the city living. The courage of our foreign investors gave us the possibility of experimenting – in the variable setup of flat interiors, new types of duplexes under the atypical roofs or to bring up new typological spaces to the market – work & live lofts on the ground floor. 9 sectional apartment houses (with 1 or 2 staircase cores = separated entrances) are set above the common “ring” of ground floor with mixed-use purpose. The “ring” protects the inner park with kid’s playground from the noise and wind coming from the main Jantarova street. All the flat roofs of the “ring” are green as gardens of flats on 2nd floor and together with the front gardens of flats on the ground floor (designed higher above pavements for better privacy) create the unique type of hybrid community living, somewhere between family and apartment houses.
Project aims to be the real first low-energy and green project in Bratislava. We designed maximum green surfaces, green roofs to keep the maximum of rain water on site for better microclimate. The heating system uses 9 deep water wells and a system of Heat Pumps (system water-water) with the possibility of cooling during the summer. The water from the wells is also used for garden watering. Altogether with good insulated facades and roofs (with designed venting gap for better cooling in white colour for maximal reflection of sun rays) and using of LED lights everywhere lead to the best grade of energy certification possible. For the needs of Opal project, we processed several comparative studies, cooperated on marketing researches and we designed and created all the marketing materials.
