The
boathouse was built as a solitary building at the Seebodner lakeside of the
Millstätter lake in Carinthia. The location of the construction is
characterized by the intersection line between water and soil, directly at the
foot a precipitous slope in which also the remaining buildings of the property
complex are situated. Due to their
elevated position, those houses have an extensive view at the south and the
west façade of the boathouse.
This
distinctive location reasoned on one hand a complicated technical and
constructional challenge, because it needed 10-metres-long drilling posts to
reach weight-bearing subsoil to construct the basement. This approach that, due
to the nature conservation and water rights notifications, was only achievable
by using a base grade, an oil barrier and several other challenging measures.
On the
other hand, this setup also meant an essential formative element in the
development of the building design: the construction body subdivides itself
into those parts of the building erected over water and those over ground, the
original shoreline can be read off the two different materials in the facades.
Moreover the wish for a grown appearing house, which in the course of the years
is permanently variable in its appearance, stood in the foreground: thus it
seems that the building, alike a reed belt, grows out of the water of the lake.
The components established over water manifest themselves completely in wood,
while those established over soil are wrapped in a cover of expanded copper.
Both selected materials, the untreated Siberian larch as well as the natural
copper panels are subjected to a natural weathering process which gives the
building an annually changing in its appearance, until the wood has turned
completely grey and the expanded metal panels are totally covered with the
green patina typical for copper.
The key
signature design feature is “hidden” in the wooden façades: on account of an
authority ban, which prohibited an outside footbridge for docking on to the
boathouse at the west facade (although there has always been footbridge in the
past), a system of facade-integrated folding elements was developed. The
uniqueness of these folding elements lays in the fact that in contrast to the
usually available folding elements, they can form a completely horizontal,
passable surface. In the open
position these gates make up the by authority eliminated footbridge in the west
façade. On the ground floor of the north facade they establish the entrance
gateways to the three boat moorings and also in the upper floor a platform over
the lake. In addition, the infinitely variable adjustable folding gates also
lead to a constantly iridescent overall impression of the building.
The spatial
subdivision of the building reflects the strictly functional and
comfort-related conversion of the space programme: located in the ground floor
is, beside the three boat moorings, one for a motor-, one for a rowing and one
for a sailing boat, the wellness area. The rooms of this area, sauna and steam bath,
as well as the changing room, are assigned to the outside space and to the
lake. In contrast the thermally separate upper floor accommodates the rooms for
solarium, massage and fitness training, as well as a small tea kitchen and a
relaxing area. The space sequence is rounded by a generous terrace on which the
cultivated vegetation extends the reed belt of the lake shore. The three levels
are connected by an open staircase which establishes the symbolical connection
between the blue of the lake and that of the sky.
The
attentive observer will recognise, that the design of the edifice and the
planting arranging of the outside areas clearly reference to the formative
elements of the existing buildings and vegetation, which have developed in a
long time, without imitating these or repeating them undifferentiatedly. By
doing so, this stylistically modern building concludes the architectural
development of the property, which already stretches for several decades, in a
contemporary manner.
