The Jubilee Library in Brighton has emerged as the bookies’ favourite to win this year’s Stirling prize after RIBA announced its shortlist this week.

The shortlist, announced on Wednesday, names six contenders for the £20,000 prize: Bennetts Associates’ Jubilee Library; RMJM and Enric Miralles’ Scottish parliament; Zaha Hadid’s BMW Central Building in Leipzig, Germany; Foster and Partners’ McLaren Technology Centre in Surrey; O’Donnell + Tuomey’s Lewis Glucksman Gallery in Cork, Ireland; and Alsop Design’s Fawood Children’s Centre in north-west London.

Bookmaker William Hill makes Bennetts Associates’ PFI library the 5-2 favourite to win the prize. The low-energy building, at the centre of a large regeneration scheme, adopted two 19th-century libraries in Paris – Sainte Geneviève and the Bibliothèque Nationale – as its design models.

William Hill makes the Lewis Glucksman Gallery second favourite at 3-1. The controversial Scottish parliament building, tipped by some to lead the race, is the 5-1 outsider, along with Alsop’s Fawood Children’s Centre.

Zaha Hadid’s widely acclaimed BMW building, almost universally praised by architecture critics, is placed at 4-1 to win the sector’s biggest prize. The McLaren scheme, backed by office specialists, is also at 4-1.

The winner of the Stirling prize will be announced at the Museum of Scotland in Edinburgh on Saturday 15 October.
