swiss firm smolenicky and partner architecture designed tamina thermal baths for
the grand resort, bad ragaz, an area in switzerland which is known for its famous
natural springs.

instead of being freestanding, the form of the building volume emerges from the enclosing
of exterior spaces. in the area of the open-air baths, for instance, the volume of the building
is stepped back and opens out the sunbathing lawn to the wooded slopes of the mountain
ridge. the view extends past the existing buildings, screened by newly planted groups
of trees.

the main entrance to the thermal baths, the spa spring hall, is set on the visual axis of
the cul-de-sac in order, from the main road, to mark its presence in the depth of the site as
a public facility.

the building volume has a monumental character, in order to stand out as an institution equal
to the other buildings in the resort.

materially the project possesses the same apearance externally and internally. the snow-white
timber battens are carried over internally as wall surfacing – so there is no definite division
between the two.

the predominant landscaped, park-like atmosphere remains intact despite the compact
manner of building. thus the resort remains characterized by its park.
