Barsinghausen / Tuebingen, January 2011. What has long been tradition in other countries will become a signature feature of the future for the Lausitzer Seenland (Lusatian Lakeland): innovative living on water. For the past two decades, the former brown coal open-cast mining area Koschen has been in the focus of scenic redevelopment. The Internationale Bauausstellung (IBA) Fürst-Pückler-Land 2000-2010 brought different projects into being which make the countryside liveable and usable again and at the same time make the past come alive. A huge lakeland area with canals was developed. It offers the locals high recreational value and attracts numerous tourists. The swimming houses of Geierswalde play a special role. In the wind-protected South-West of the artificial lake of the same name, the Lausitz Resort is the bridge between water world fun parks and living.
Over the next few years a total of 20 houses are planned on the water and nine on land, connected by a 24 meter long shore bridge. The water buildings dock at the 60 meter long, angled pier in a staggered fashion. Their basic form is cuboid, but one side wall is replaced by a curved metal roof surface which extends all the way to the ground. The association of a sail on the water is obvious – or, lined up in the dock, a small fleet of ships. A continuous glass façade
supports the visual lightness of the construction. In interaction with the open-plan interior, it offers view relationships in all directions. The lower level of the module house with kitchen, dining area and bath is dedicated to the supply, the calmer areas for living and sleeping are arranged above. An outside staircase establishes the connection to the generous sun deck.
The prototype in steel construction, which can also be erected on land in modified form, was developed by steeltec37. The design was provided by WIL/DESIGN and Wilde Metallbau GmbH manufactured the houses.
The modular construction of the prototype allows flexible design of the 97 square meter floor space. An unsinkable steel pontoon forms the base, a self-supporting frame construction of rectangular steel tube
profiles. The façade is also constructed of steel profiles.
Its high glass component requires highly-efficient heat protection and therefore a real high-tech product. That’s why the GEWE-therm® triple heat insulating glass
protects against the cold in winter and overheating in summer. With realisable Ug-values of up to 0.4 W/m2K the insulating glass is neutral when looked at and looked through. The units consist of several panes arranged one behind the other, the spaces in between being filled with inert gas. Inert gas is excellent for thermal insulation because it has a many times greater insulating effect than air. The glass surfaces also have thin precious metal coatings. They lie protected in the space between the panes and ensure that long-wave heat rays are reflected to the outside and short-wave rays are allowed into the room. During the cold season, this keeps the expensive heating energy in the room and the cold stays outside. At the same time the warming rays from a setting sun can be used simply and effectively for heating up the rooms situated behind, which saves additional heating costs on cold days and makes them feel cosier. Vertical blinds in front additionally guarantee shade and privacy. In areas where these cannot be installed, “intelligent” glass takes care of privacy protection. It can be changed from transparent to milky by the press of a button. A liquid crystal film makes this possible. When power is added, the crystals move from the ordered into the disordered state and therefore become translucent.
In the exposed region, the “Residential Fleet” captivates through its glassy charm which also presents itself at night when the light reflections from the houses dance on the water.
