This week on Dezeen, British practice David Chipperfield Architects completed an overhaul of Ludwig Mies van der Rohe's Neue Nationalgalerie in Berlin and revealed a skyscraper in New York.

In Berlin, the studio carried out a "surgical" renovation of Mies van der Rohe's museum, which is the only building he designed in Europe after his emigration to the USA.

David Chipperfield Architects aimed to retain the architect's original vision for the gallery while updating the ageing structure and reorganising the lower floor.

Meanwhile in New York, the studio unveiled The Bryant. The 32-storey concrete block in Midtown Manhattan, which overlooks Bryant Park and the New York Public Library, contains a hotel and residential apartments.

This week the organisers of Milan's Salone del Mobile ended speculation that the event would be canceled or moved to a smaller venue by confirming that the furniture fair will take place.

The fair, considered the most important design fair in the world, will run as planned at the Fiera Milano exhibition centre from 5 to 10 September.

In other design news, American journalist Evan Townsend shared his design for an Antarctic flag – which he believes is the first to be widely used on the continent.

Named True South, the flag was designed to give the largely uninhabited continent a distinctive identity and for others around the world to focus on its protection.

"True South is the first flag to be created, supported and adopted by members of the global Antarctic community," he told Dezeen.

The Oscars were awarded this week in California with a live audience attending. The ceremony took place in the main ticket hall of LA's art deco Union Station, in a set designed by US architect David Rockwell.

Rockwell aimed to recall the glamour of past Oscars ceremonies in his design.

In London, UK studio Adjaye Associates unveiled a triangular memorial to Cherry Groce who was wrongfully shot by police in 1985.

Built in Brixton, where Groce lived, the structure is formed of two triangles that act as seating and canopy, connected by a single column.

Popular projects this week included a Japanese-informed wooden apartment building in Paris, a hotel in Miami created by American designer Ken Fulk for musician Pharrell Williams and a boutique hotel in Puerto Escondido.

This week's lookbook focused on courtyards and enclosed outdoor spaces.
