This week on Dezeen, RIBA revealed the shortlist for this year's Stirling Prize, which includes a mosque, a bridge in Cornwall and a museum in the Lake District.

Alongside Cambridge Central Mosque (above) on the six-strong shortlist was 15 Clerkenwell Close, designed by Groupwork.

The building was a surprise addition to the shortlist as, unbeknown to its architect, it was withdrawn from consideration for the prize in 2018 due to a planning dispute between the studio and the council.

Speaking to Dezeen following the shortlisting, Groupwork's founder Amin Taha said he was "speechless".

Also in awards news, Glenn Murcutt was named the winner of this year's Praemium Imperiale for architecture, which is awarded each year by the Japan Art Association.

Murcutt, who is the first Australian to win the prize, was described as an "architect ahead of his time" in the award's citation.

Following the announcement of the Dezeen Award shortlists last week, we have opened the voting for this year's public vote.

You can vote now for your favourite projects, which will receive a special Dezeen Awards 2021 public vote certificate.

In interiors news, paint brand Dulux revealed its colour of the year.

The brand picked an "airy, light blue" colour called Bright Skies as it "perfectly captures the optimism and desire for a fresh start that is the mood of the moment".

We also reflected on last week's Milan design week, which took place in a reduced capacity due to the continuing coronavirus pandemic.

"It's completely different to the other editions," designer Luca Nichetto told Dezeen. "It's totally another rhythm. I prefer it this way because you can actually speak more deeply."

Popular projects this week included a boathouse in Austin with perforated metal facades, the renovation of a mid-century house in East Sussex that was informed by Sri Lankan architect Geoffrey Bawa and a concrete house in the Arizona desert.

Our lookbook this week focused on mid-century modern interiors.
