That all architectural structures are covered by solid opaque walls on all four sides to maintain privacy and security is a given. So, a home with walls of glass that offer a clear view of the inside is bound to create more than just a ripple, and 128 Werner Sobek does just that. This rather novel concept in residential architecture seems to have broken through all conventions and set a new - if not higher - standard in innovative construction.

R128 Werner Sobek is four-storey house, floating high on a hill overlooking the city of Stuttgart, Germany. Inside this curious creation, there are no doors, switches, interior walls or partitions and no closed rooms. But what takes the cake is that the home generates its own energy. The construction material used to create R128 is one hundred percent eco-friendly and recyclable.

R128 has a most attractive glass façade and is devoid of a basement. High quality triple-glazed glass with inert gas filling is in use. The use of a modular design, complete with glass panels and steel frames ensured easy assembly and disassembly of the construction. The insulated glass panels prevent overheating of the interior during summer and loss of energy and warmth during winter. The supporting steel frame comprises of 10 tons of steel.

The ceiling of the Werner Sobek glass house consists of prefabricated panels overlaid by plastic. Beneath the unscrewed floor, aluminium ceiling panels are affixed by clip connections. Lighting, heating and cooling systems are fitted into that layer and this acts as an acoustic absorber pattern.  

Sensor controlled doors have been installed on the upper and lower levels of the house. All appliances and environmental systems are also controlled by motion sensors and voice commands. The front door has a voice recognition feature which allows it to open automatically on a voice command. Water faucets in the bathrooms are regulated by sensors. Windows are controlled by touch screen technology.

Every floor has two folding windows each, which allow natural daylight and fresh air to enter the house. During summer, cool water running through the floor elements removes excess heat from the entire house with the help of a heat exchanger. Thus surplus energy is stored for use in winter. This ensures minimal energy consumption. 48 solar powered modules with a total capacity of 6.2 KW are installed on the rooftop, which are responsible for supplying all the power required by the pump system.

This green show-house is expected to go a long way in promoting energy-efficient architecture.
