Located on a steep hillside in the Italian Dolomites this new-built hotel has been developed as the interweaving of the free-flowing topography - indexed and organized by series of timber strips - and the serial sequence of apartment units perpendicular to it.Skin organisation as strataSince the overall shape was developed from the local planning guidelines, the linear distribution of units and the views and sun directions, it is a resultant of the constant negotiations among all these parameters as well as a topological answer to the picturesque typologies frequently built in the area. From applying the logic of topographical mapping i.e. the indexing of horizontal sections as continuous lines, the volume is formed as a series of strata that as an artificial entity maintains a dialogue with its natural environment. In addition these horizontal sections operate as control lines, enabling the generation of curved hyperbolic-parabolic geometry.The balconies become in-between zones that negotiate the internal rationale of the apartments - ruled by efficiency and the repetition of parts - with the exterior - as extension of the topography.The building is an extension to an already existing apart hotelThe old and the new part connect by an underground level and through a mediating low and inconspicuous building volume at ground floor level. The main building volume distinguishes consciously from the existing part.Programmatically the new volume is divided into two parts: the right side of the wing is a rigid addition of the axis of the guestrooms, all directed to the views and the sun, the left one together with the mediating building is occupied by the private house of the client. The guestrooms are all developed as family apartments. Each room has a balcony and the façade behind is fully glazed. The bands surround the volume at different scales, peeling off from it, flowing into the landscape and blurring the boundaries of the building.
