Revier Mountain Lodge Lenzerheide 46°740'912"9°555'840
Ceilings, floors and walls are constructed as modules made of cross-laminated timber; pure structural timber without any doubling – serving as the supporting structure, room divider and surface finish all in one. The arrangement of the rooms in a row creates a double-shell structure that meets even the most stringent sound insulation requirements. The ready-to-install room modules, including a multifunctional bathroom unit, were manufactured in the factory. This has enabled a high standard of finish as well as a short construction and assembly time on site. Modern technology and unpretentious design come together here as a matter of course. On the façade of the four storeys of rooms, the individual modules are accentuated by protruding metal frames. Otherwise, the building is a clear timber structure with vertical boarding made of rough-sawn, untreated larch.

The Hotel Revier in Lenzerheide is
designed for guests who wish to indulge
in outdoor sports. Accordingly, the architecture is stripped back to the essentials and conveys
a sense of freedom: the long, narrow
building stands on the steep edge
of the mighty mountain forest in the background.
With two gentle bends, it follows the shoreline
of Lake Heidsee. The front section on the ground floor of the hotel opens out towards the valley station of the Rothornbahn
and, with its lobby, bar and restaurant,
is the place where people meet. The
massive ground-floor plinth also houses the spacious winter sports and bike room. Above this are four further floors with
a total of 96 rooms, all facing west
towards the water.
The experience of travelling in a VW campervan provided the inspiration for the design: you park right by the lake, open up the rear and feel free.
A large bed stretching from wall to wall,
a floor-to-ceiling panoramic window with
an integrated ventilation flap, and a wide
window sill emphasise this concept.
The compact bathroom is positioned within the room as a multifunctional unit. A standard room measures just 15 m² in floor area. Ceilings,
floors and walls are constructed as modules
in spruce cross-laminated timber. The
construction timber used serves as the
support structure, room divider and surface all in one. In addition to the standard rooms, the hotel
offers four accessible rooms and 28 triple rooms.
By arranging the rooms in a row,
a double-shell structure is created, which also
provides good sound insulation. Various
details enhance the functionality of the rooms:
the large radiator in a recess can
be used to dry gloves and
clothing, there are hooks for hanging
bulky items, and the bed can be used for
watching TV and relaxing. An
automatic folding mechanism also makes
making the bed easier. The series production of the fully fitted room modules in the factory
ensured high build quality as well as
short construction and installation times on site.
This is because the hotel rooms were
manufactured in the workshop whilst, in parallel,
the structural work was carried out and the
ground floor and stairwells were constructed
in concrete. This is one of the reasons why
the decision was made to opt for timber construction.
Vertically, the load is transferred via the
double-skinned partition walls. To meet
sound insulation requirements, the loads in the area of the floor slabs are transferred via plastic bearings.
The modules on the upper four storeys
transfer the loads to the reinforced concrete
slab above the ground floor, where the
structural grid changes. An interesting
concept was developed for horizontal
load transfer: to prevent structure-borne
noise transmission and achieve the greatest
possible decoupling of the components,
rigid connections between the modules. For load transfer in the longitudinal direction of the building, the modules in the central area are situated between the solid, oad-bearing reinforced concrete cores; the outer
parts of the building are suspended via prestressing cables in the area of the floor slabs from the respective reinforced concrete core. The transfer of compressive forces is achieved via sound-insulating plastic bearings. In the transverse direction, the loads are transferred via the cross-laminated timber panels of
the interior partition walls.
As far as fire safety is concerned, the visible
cross-laminated timber panels are designed in terms of thickness and construction in such a way that the requirement for a 60-minute fire resistance rating of the structural framework is demonstrated during a burn-through test. The exterior of the building conveys a rigorous and simple design language: a vertically profiled
metal cladding surrounds the concrete plinth,
above which lie the four storeys of timber
with vertical façade cladding made of
unplaned, untreated larch. The protruding
metal frames emphasise the individual
modules in the façade. Horizontal and vertical
fire protection measures ensure compliance
with the protection objectives for the
façade.
