In its design for the housing project CJ5, Caramel tackles the question of sustainable urban density on the outskirts of Vienna.Save this picture!SectionRecommended ProductsEnclosures / Double Skin FacadesIsland Exterior FabricatorsCurtain Wall Facade SystemsEnclosures / Double Skin FacadesFranken-SchotterFacade System – LINEAEnclosures / Double Skin FacadesAlucoilStructural Honeycomb Panels – LarcoreEnclosures / Double Skin FacadesRodecaRound Facade at Omnisport Arena ApeldoornBuilding heights of between 4.5 and 7.5 metres are permitted for the type of building prevailing there, which allows for the construction of estates of two-storey detached or terraced houses. On the one hand, they display a high individual quality of life, with adjacent gardens and terraces on the living level, but on the other hand they result in very high space requirements due to their low floor area ratio FAR (= usable living area / property area) of 0.2 to 0.4.Save this picture!© Hertha HurnausFrom an infrastructural and space-saving perspective, it would be worth striving not only for a denser flat construction style (FAR 0.4-0.8) for these areas, but also a FAR of 0.8 to1.2, which at present is only achieved by means of densely built multi-storey apartment blocks.Save this picture!© Hertha HurnausWith the pilot housing project CJ5, Caramel Architekten have completed a project which both maintains the qualities of the single-family house, with a generous garden and terrace on the living level, and attains a FAR of 1.0. It is therefore more densely constructed in comparison to a multi-storey apartment block which comprises several units, but does not have any direct connection to the exterior space > see visual ‘Site plan and floor area ratio’Save this picture!Ground Floor PlanThis has been made possible by means of a narrow floor plan layout of 5 x 35 m, with a three-sided firewall to allow the possibility of direct extension, an internal connection between the living levels, a central atrium garden and focused horizontal and vertical lighting areas.Save this picture!© Hertha HurnausFrom the outside, one enters a relatively enclosed white spatial sculpture, which then continues to open up vertically as one proceeds from the studio / garage in the entrance area to the living area and atrium garden. In this way, an internal set of very spacious interlocking rooms is developed, despite the narrowness of the property.Save this picture!Courtesy of Caramel ArchitektenThe external white cube is continued as an inner white cube in the studio / garage and in the basement cinema. In the case of the living and office area located behind, the interior and exterior are connected by means of continuous fair-faced concrete surfaces with a boarding look on the walls and ceilings, as well as continuous wooden floor coverings running in the same direction as the visual effect of the boarding on the walls. This creates a spatial continuum which extends via the central kitchen landings as part of the landscape of the staircase (CJ5 = Cooking-Jay-5m wide) and the studio, to the bedroom area on the upper storey.Save this picture!© Hertha HurnausThe bathroom and toilet, which are adjoined at the side, are then respectively developed as separate islands of colour, using tiles of the smallest possible format. The ‘room in room system’ creates views through all the rooms of the living and office areas and out onto the central external element, the garden atrium.Save this picture!Courtesy of Caramel ArchitektenAs far as energy is concerned, the house is almost completely independent. It supplies its own needs from photovoltaic panels on the south-facing areas of the roof, and from an air-to-water heating pump. It has also been developed as a low-energy house with respect to its insulation values (heating requirements 41 kWh/m²/a).Project gallerySee allShow lessTicollage City / Costa Rica Pavilion at the Venice Biennale 2014Architecture NewsCritical Round-Up: The 2014 RIBA Stirling Prize ShortlistArchitecture News Share Projects CJ5 House / Caramel Architekten photographs: Hertha HurnausPhotographs: Hertha Hurnaus, Courtesy of Caramel Architekten+ 17 Share ShareFacebookTwitterPinterestWhatsappMailOrhttps://www.archdaily.com/527124/cj5-house-caramel-architekten Clipboard CJ5 House / Caramel ArchitektenSave this projectSaveCJ5 House / Caramel ArchitektenSave this picture!© Hertha HurnausHouses•Vienna, Austria CopyAbout this officeCaramel ArchitektenOfficeFollowProductsWoodConcrete#TagsProjectsBuilt ProjectsSelected ProjectsResidential ArchitectureHousesViennaHousesAustriaPublished on July 21, 2014Cite: “CJ5 House / Caramel Architekten” 21 Jul 2014.
