The RIBA London Regional Awards nominees have just been announced, marking the beginning of the 2015 RIBA awards cycle.

The Regional list in turn leads to the RIBA National Awards, which in turn gives birth to the highly coveted Stirling Prize. The London winners, judged separately across four regions within London - west, east, north and south - will be joined by the separate winning design lists from across the UK, forming the full RIBA Regional Awards for 2015.

As always, the capital's wealth of shortlisted buildings spans different scales and typologies, ranging from the Bonhams Headquarters in the UK capital by Lifschutz Davidson Sandilands through to Gianni Botsford's tiny 'White on White' house extension in North London. Also shortlisted are Kew House by Piercy & Company, Waddington Studios by Featherstone Young Architects and Fitzroy Park House by Stanton Williams. With each, architectural excellence is key.

The London winners will be announced at the RIBA London Awards ceremony at the National Theatre's Temporary Theatre on 18 May.
