Local architects will be pitted against world famous icons to find the best building in the world at the World Architecture Festival (WAF) Awards.
Contenders for the prize include zoos, police stations, cutting-edge football stadiums and airports.
Top architects such as Lord Foster of Thames Bank, Richard Rogers, Frank Gehry and Zaha Hadid are almost always in the front running when it comes to awards.
But according to WAF awards Programme Director Paul Finch the most significant building in the world in any given year is not necessarily the most high-profile.
"It could be that a primary school in Glasgow or a small church in Peru is actually the building doing most to alter the way we think about the building type," Finch told The UK's Times newspaper.
The WAF prize is backed by 26 architectural magazines from five continents and covers 96 types of building split into 16 main categories.
There are awards for churches, mosques and synagogues, hotels and visitor centres, to name a few.
The festival takes place from 22 to 24 October in Barcelona.
