The Titlis antenna tower was built in the mid-1980s as telecommunications infrastructure. Due to its exposed location over three thousand meters above sea level, the tower is anchored deep into the limestone mountain by a concrete structure and built with an almost filigree steel framework. The tower is defined by this existing steel structure, which we extend and develop with the addition of two horizontal volumes and four vertical circulation towers.
From the base, visitors ascend through the four vertical circulation towers, which complement the existing steel columns at each corner, leading all the way up to the viewing platform. The two fully glazed horizontal volumes extend in far-reaching cantilevers and overlap in a cross-shaped arrangement, creating a striking figure visible from afar while offering impressive panoramic views of the alpine landscape from within. The external load-bearing structure allows the interiors of the two new volumes to remain entirely column-free. More info at hdm.com
