With the RIBA Regional and National Awards done and dusted, the time is nearing for the next round of British honours – and indeed, the shortlist for the highly coveted RIBA Stirling Prize has just been announced.

Spanning six exceptional structures, located in various spots across the UK, this year's highly anticipated list is composed of the Blavatnik School of Government, University of Oxford, by Herzog & de Meuron; the Riverside Campus, City of Glasgow College, by Michael Laird Architects and Reiach and Hall Architects; the Newport Street Gallery, Vauxhall, by Caruso St John Architects; the Outhouse, Gloucestershire, by Loyn & Co Architects; Trafalgar Place, Elephant and Castle, London, by dRMM Architects; and the Weston Library, University of Oxford, by WilkinsonEyre.

As with the recently revealed RIBA National Awards, education buildings have a strong presence in the Stirling battle – with the University of Oxford specifically being represented not once, but twice on the list. Both its round glass Herzog & de Meuron Blavatnik School of Government and the redesigned Weston Library have been highlighted by the RIBA awards judges.

Meanwhile, the residential typology has all scales covered, espeically in the partly subterranean Outhouse single family home in the Forest of Dean and Trafalgar Place, dRMM’s south London high-density housing scheme. It is also worth noting that while the nominees include some Stirling Prize veterans, there are newcomers in there too; Michael Laird Architects and Loyn & Co Architects are shortlisted for the very first time.

The winner will be announced at a ceremony in London’s RIBA headquarters on 6 October. Now in its 21st year, the Prize, this year sponsored by Almacantar, also has a supplementary book coming out in the autumn, celebrating two remarkable decades of accolades.
