Chilean architecture duo Pezo von Ellrichshausen has installed a mirrored structure within Milan's Palazzo Litta, creating disorientating reflections of its baroque architecture.
Described by studio founders Mauricio Pezo and Sofia von Ellrichshausen as a "magic open box", Echo Pavilion offers two types of reflection ? some are the right way up, while the others are upside down.

The pavilion is located at the very centre of the palazzo's courtyard. It lines up exactly with the building's windows, columns and other details, but also with the paving patterns on the ground below.
A cube forms the base of the structure, while the upper section is an inverted pyramid that slopes outwards at a ratio of 1:2, in line with the proportions of the courtyard and the palazzo walls.
"We decided that the most important aspect of of the whole place was the place in itself," explained Pezo.
"Everything is based on the existing structure ? the proportions, the size and the angle of the opening ? everything relates to the existing building," he told Dezeen.
"We wanted to make something that would be imposing but, at the same time, very humble and very invisible."

The pavilion is clad in polished stainless steel, which provides the reflections. But inside, the mirrored surface completely disappears and the structural framework is revealed.
"The inside shows you the tremendous effort and structure that's needed," said Von Ellrichshausen.
