The striped, optically intermeshed glass and aluminum façade characterizes the visual appearance of the new

Alongside the façade, the glass roof that covers some
100 square meters and slopes inwards at an angle of
three degrees towards the building’s inner courtyard
constitutes another architectural highlight. This was
constructed using the RAICO THERM+ S-I steel mullionand-transom system with a width of 56 millimeters.
Identical to the basic THERM+ systems in its technical
characteristics, the glass roof provides the same
properties and functionality as a curtain wall system
constructed from the same components. The RAICO
specific fixture technology means that there are no
superimposed components and thus ensures optimum
protection against corrosion. To ensure efficient
drainage, a segmented run-off technique was used in
which each glass surface is drained separately by means
of a vaned transom gasket. This solution guarantees the
controlled removal of any condensates that occur.

A fully glazed, 90-meter high steel pyramid on
the ‘Little Matterhorn’ to take it to a height of
4,000 meters? A luxury hotel above Zermatt that
has already become a legend even though it has
been open for only seven weeks? Or steel cubes
measuring 30 centimeters scattered by helicopter
over the surrounding mountains to become
naturally formed artistic objects? These and
many other projects bear the hallmark of Heinz
Julen, the Zermatt-based action artist, architect,
painter, sculptor and designer. His architectural
agency here is housed in a former stables dating
from 1818 and at the back of which Heinz Julen’s
own workplace can be found. All the fittings and
equipment such as the tables, chairs and lamps
come from his own workshop. Alongside the
desk, the back wall of the office is constructed
from natural rock. “It is a place of power and
inspiration that lends wings to the imagination”
says Heinz Julen. Here, he works with his team to
put his projects into practice and combines daring
visions with long-standing, local tradition. By
using wood, leather, stone and glass, he creates a
relationship with the natural environment and, in
doing so, conjures up a very special atmosphere
– as in the case of his design for the Hotel
Matterhorn Fokus (presented in RAICO OBJEKTIV
1/2010) or in his own Backstage Hotel whose
entire internal fittings he designed himself.
