Originally, this house designed by Architecture aluminum UNIT AB in Sweden lake Gärdsken are wooden two-storey houses with basements in rock and popular retail. The aluminum case design is based on brick walls. The lower floor is constructed from 220mm beams, while the roof is supported by glulam beams. As the home front material was selected 3 mm anodized aluminum plates are coated with stainless steel countersunk screws on an adjustable frame galvanized steel. All plates are prefabricated in the workshop. The extension is heated with underfloor heating.
There is a well-developed grammar of Swedish culture of how to enlarge the construction design of the house with traditional gable roof, a ridge generally perpendicular to the existing. To achieve this objective requires that the extension is subject to size. The ability to build a fairly traditional style has been tested in a sketch, but was deemed too intrusive because of its size. The new wing "eaten" the old house. Thus, the architect chose instead to target the maximum contrast in the expression.
In the eastern part of the plot is a beautiful old trees position. The movement is proposed in this project follows the principle often used in the art of Japanese gardens, the first place in the main view (the garden), then disappears from view - but not forgotten. In the third step of the sequence of the viewer is facing the garden. A large plate is the custom item that hides the garden in the second stage and the form of a filter between the foyer and living room overlooking the garden.
A new hallway and entrance is established between the new building and the existing house. From this corridor almost every room in the house can be reached and it can also give a more representative input from the living room if necessary. The new room has a maximum opening of the garden, but it is closed to the streets to ensure confidentiality. Also known urbanism Office for Windows in the front wall to brighten up the printing of the street. The solution was to shape the aluminum panels of the facade as a trellis growing vines. It always takes time for vines to establish, therefore, the architect has designed a model that provides a quality of realism to the facade of the lack of green space. The laser-cut design is inspired by vineyards and produces a form favorable for spins to climb.
In Sweden, there is a long tradition of working with steel plates (about 0.6 mm thick) that connects the different sheets with creases to achieve an impermeable surface. This technique is mostly used on horizontal surfaces when used on the facades of steel (about 1.0 mm thick) is often folded in cartridges for greater rigidity. Both applications will result in a surface tension and unprecedented movements due to temperature combined with the fragility of the thin plate. Japanese architect Fumihiko Maki with as master developer has a highly developed tradition of using thicker plates in the walls. These provide an accuracy quite different and a smooth feel and require further details, because they can not be formed in situ sheet metal workers. As the architect wanted a contrast between the design of existing and new building, the architects chose to 3mm thick aluminum plates to achieve high accuracy.
Aluminum can be used with raw or anodized finish. Finally, the forms of primary aluminum, an oxide, but it's just one hundredth as thick as that achieved in the anodization. It also makes a more organic feel with ridges running water and a dynamic finish. One advantage is the ability to bend raw aluminum on the site.
As an architect who searched precise expression, the architect chose anodized plate. Discs treated first mechanically and then sent to the finishing of the company through the electrolytic process created in the oxide layer thickness of selected dishes (25 micrometers in this case). It offers 100 years of resistance, which meets the customer's request for low maintenance. This is a hard and brittle oxide as a glaze on the hardness of China makes it impossible to do without breaking any license plate anodized in this layer.
Architect selected tables automotive manufacturing subcontractors. If anyone dares to say that the Swedish construction companies are often involved in questionable places, subcontractors, Saab and Volvo to excel in a high level. They serve as digital manufacturing and industrial tolerances + / - 0.1 mm compared to the construction tolerance of + / - 10mm. Riboverken Göteborg, laser cut sheets of all the CNC (Computer Numerical Control), the designs of the architect. In this process, it is expensive to cut a curved line as straight. When the prefabricated panels, you get the clash of two different tolerances, and the inaccuracy of the exact area dotted frame. This has been fixed Adjustable front panel frame.
The model is catching in the gears of a plant because they are developed by the architect and translated into digital manufacturing plans, also Riboverken laser cutting. Laser cutting can be done to a certain thickness. For thicker plates that you have to switch to water-jet cutting. Aluminum is available in a variety of alloys and because the architect wanted a small radius of curvature and the architect chose anodized alloy 5005. Photographs:
