Sharp contrasts and a tin box-like structure, the White Deer Plain. Mountain Land Resort Hotel offers a strong vision of different material usage and highlights the perpetual battle between light and shadows through its shapes and framework. The space and dimensions of the building remind the viewer of the ratios and relationship between human and architecture.

Interior Design of the Year

Technopolis Auditorium: An acoustic device

The Auditorium was a renovation project designed for the Municipality Of Athens, completed recently in the cylindrical Historic Industrial Gas Park building. Keeping with the concept of a gasholder tank, the forms of the inner design fold and flow, transforming the auditorium into an “acoustic device.” The roof enhances passive acoustics through geometric sound reflectors and absorbers and oak surfaces that form prismatic clusters. In total, the structure consists of 564 elements coming together into an alluring, jubilant meeting spot for art lovers.

Property Development of the Year

Park Silom

“Silom” translates to “Windmill” in Thai. Historically, the area was a humble rural location that, with the evolution of Bangkok, became the financial district. At Silom, the windmill symbolises new beginnings, which is reflected by the intention of breathing new life into the community right from the heart of the building. The o ice complex is a38 storeys with two basement levels and 56,000 square metres in total area.
