Our passion and drive have been instrumental to the success of numerous projects both domestically and all around the world.
All of those projects have different characteristics, different background stories and different specific requirements.
But each and every one of them embodies our whole experience.
They are all unique.
From industrial hangars to high-bay warehouses, from bold suspension bridges to glass skyscrapers in the world’s largest cities, we have realised more than 2000 projects over the years.
The following selection showcases our various areas of competence.

Ljubljana 2020

Shopping center

Aleja Laibach shopping and district centre 

The ALEJA complex in Ljubljana, planned by ATP architekten ingenieure, is one of Europe’s most modern shopping centres. The building owes its striking appearance especially to its extraordinary façade. Rows upon rows of colourful, diamond-shaped stainless steel shingles imitate the scales of a dragon – the symbol of Slovenia’s capital. The curved rhombus façade of the entrance represents the dragon’s head. PICHLER projects was in charge of implementing the 12,200-square-metre façade and five large glass roofs with a steel structure. Several architectural challenges had to be overcome. 

For instance, the complex, rhomboidal entrance façade, which rests on a spatially curved steel substructure carrying both the diamond-shaped glass panels and their stainless-steel counterparts. Due to the complexity of the façade structure, many different nodes in the steel substructure had to be produced with special milling machines. At the PICHLER projects production facilities in Bolzano, the individual steel shapes were welded together with the corresponding node parts. Then, a steel profile was added that would facilitate the later incorporation of the glass and stainless-steel panels. Finally, the individual diamonds were welded together on site, and the fillings were installed. 

The glass-diamond façade structure of the building envelope makes the weather visible on the inside. Thanks to the alternatingly open, half-open and closed elements making up the façade, sunshine and clouds conjure up a breathtaking display of shadows on the building floor.
