Singapore's Parkroyal on Pickering by Woha Architects and SkyTerrace @ Dawson by SCDA Architects are on a longlist of 30 buildings around the world being considered for the inaugural Royal Institute of British Architects International Prize.
The institute - known for the past two decades for naming the best British building - will award the prize for the best global project.
The first round includes 30 buildings in 20 countries. The award will be announced in December.
The projects range from private homes and places of worship to large infrastructure developments. Here are four projects that made the longlist.
SKYTERRACE @ DAWSON
The award- winning project in Queenstown, Singapore, has five residential blocks 40 to 43 storeys high. Designed by SCDA Architects, it has six sky gardens and features eco-friendly features such as solar energy systems to power lighting in common areas.
PARKROYAL ON PICKERING
Sky gardens are a highlight at this project in Chinatown, Singapore, which opened in 2013 and was designed by Woha Architects. The curvy facade is inspired by terraced padi fields and is decorated with more than 10 species of plants, including palms and creepers.
This mosque in Istanbul, Turkey, overlooks Lake Buyukcekmece. Terraces on the sloping site double as steps and lead to the building's entrance. The cave-like interior offers one a quiet space to contemplate and pray. It was designed by EAAEmre Arolat Architecture.
HEYDAR ALIYEV CENTER
Designed by the late architect Zaha Hadid, this project in Baku, Azerbaijan, features the curvy aesthetic of the Pritzker Prize winner. It houses a museum as well as a 1,000-seat auditorium. It won the Design Museum's Design of the Year Award last year.
