An Edinburgh roof extension, a house that cantilevers across a beach and Steven Holl's new wing for the Glasgow School of Art are among the projects shortlisted for Scotland's national architecture awards (+ slideshow).
The Royal Incorporation of Architects in Scotland (RIAS) has announced 24 nominees for its annual awards, which will be announced at an event in Edinburgh on 17 June.
Other projects recognised include a new auditorium for the 1930s-built Glasgow Film Theatre by NORD Architecture, a Maggie's Centre for cancer care in Lanarkshire by Reiach and Hall Architects, and a Scotch whisky distillery by Archial Norr.
"It is a huge credit to the profession in Scotland that, despite sometimes savage cost cutting, the remarkable work illustrated in this shortlist is still being produced," said RIAS secretary Neil Baxter.
The judging panel, which included architects Julia Barfield and Hugh Dutton, will now visit all 24 projects before selecting the overall winners of the RIAS/RIBA Awards 2015. All 24 projects will be eligible for the RIAS Andrew Doolan Award, recognising the best new building in Scotland, as well as the RIBA Stirling Prize for the best contribution to British architecture in 2015.
