Plastic Houses / Units AB architecture
In Hjuvik outside Göteborg och Anna Marcus Bohlin buying a property containing an old house. This area is purely residential area that has been fully developed during the last 20 years with a high density of houses in a row.
This also causes the paradox that, although all residents have settled to see the sea, the sea can not be seen from their property as their neighbor’s house near by blocking the view.
This, combined with current building regulations that Sweden has a kitchen, living room, bathroom and bedroom should be accessible to persons with disabilities, led to the tragic reality that, despite the proximity of the sea, Most people do not see the room where they spent most of the time their savers – the kitchen and living room.
In the first calculation, proved too expensive to extend the existing house and had been destroyed as a result. This foundation has been saved and thus determine the depth of the new building. From the ground floor in this case, the position was dark and narrow, it is desirable to move the story – to get a room and into the living room and kitchen. It was possible to prepare dishes lift outside the building, if the house must be adapted for the disabled in the future.
Customers want a bigger house that the budget really permits. This is made possible by a very simple geometry and general material to follow the logic of the external shape and layout of a shoe box as easy as possible. That is the size of the room which was defined as a luxury, not a building material.
Material from the facade reflects the various activities within the home. Ground floor houses the main bedroom, private housing and non-representative. The front of this floor of the building facades are clad with Sweden’s most – sawn pine boards. It is painted with a mixture of equal parts of turpentine, linseed oil and tar – the west coast of the traditional treatment of health coverage for their wooden landing. This floor has a traditional investment in Windows. Upstairs is a representative section and facade of the house wearing perfectly good materials – 5 mm white translucent acrylic plastic or PMMA. Captured with a panoramic view of magnificent large windows. A large balcony with a grid of steel construction and low-cost pragmatic compensate for the lack of open space in the living room.
The ground floor has a pragmatic level, built around an alley across from storage as a buffer to the north. On the other hand there is a row of rooms. Top-level inspired by Moore and houses Kubly – both designed by Craig Ellwood and built in the 60s – with their free walls interrupted only by the sliding door closed.
The material in front of the upper floor consists of sheets of opaque 5 mm acrylic glass. PMMA – polymethyl methacrylate – has been developed in the 20s in Germany and marketed in 1933 under the brand name glass. Already during the Second World War equipment used in various military applications, like a periscope, wind screen, etc.
PMMA has the ignition point of 460 ˚ C and other forms of carbon dioxide and water during combustion. He has less than half the density of glass production requires about two liters of oil to produce a kilo of PMMA. The material is UV stable, making it suitable for outdoor applications.
Two factors are important considerations when designing with PMMA. The first is the expansion of the extreme length of the text, in various temperature of 100 ˚ C design, estimated at 7 mm of expansion per meter. This means that when you can not allow continuous movement is limited to a relatively small leaf size. Second, electrostatic plastic so it can not attract dirt particles and growth.
After considering various methods of setting by considering these factors, and we concluded that 3M’s band will be the best solution in terms of technology and aesthetics. The proposed technique is to place the leaves with acrylic foam tape with a dimension as the width, thickness and appropriate choice of foam. Because no previous experience of implementing PMMA adhesive tape, 3M has conducted experiments in a hot room to justify the procedure. strip thickness must be counted for one third of thermal expansion, so the strip thickness 2 mm was chosen. tape was applied to the surface treated steel strip, galvanized surface is not stable over time.
Leaves from the PMMA is applied directly to the struts, which depends on the temperature of about at least 15 ˚ C at the time of application. Because of the historical cost of the cold spring has unfortunately too high to maintain the scaffold until the temperature is on the right. Therefore, the leaves that have traditionally been installed with screws at the top.
