Berlin's Barkow Leibinger has won an invited competition to design a new hotel tower and conference centre as part of Berlin's largest hotel complex, the Estrel. Establishing a new gateway to the center of Berlin from Schönefeld International Airport, the tower will stand at 175 meters (578 feet) making it the tallest high-rise in Berlin to date. Located on the Sonnenalle at the intersection of the Ship Canal, S-Bahn and Autobahn, the site acts as a threshold between the heterogeneous industrial and residential periphery of the city and the historical neighborhoods of Neukölln.

It proposes an itinerant soil-less agricultural infrastructure designed to drift the circulating ocean currents between Greenland and Canada, exploiting the nutrient-rich fresh water released by melting icebergs as the basis for a large-scale hydroponic-farming system. The floating facility is equipped to house a community of 800 people, inspired in its compact urban form by vertically oriented, bayside Greenlandic villages and their social, cultural and economic relationship to the sea.

Amsterdam-based NL Architects has been shortlisted, alongside three other prestigious teams, to design a new “ArtA” museum and film house for the city of Arnhem. Uniting four main programs - a cinema, art square, museum and park - the “wedge-shaped” structure is designed as an “urban moraine” that cascades towards the city and invites residents to experience the Rhine from an elevated parkway. This formation grants pedestrians two options for museum access: up the Baroque-inspired rooftop park or through the ground level “Art Square” which serves as a “public intermediary” between the building and city, as well as the museum and film theatre.

Kengo Kuma, one of four renowned architects competing to design the highly anticipated ArtA cultural center in Arnhem, has shared details about their shortlisted proposal.
