Alastair's main project is Scotland's Lost Country Houses. Like their English and Welsh counterparts, many of Scotland's country houses were lost in the 20th century. This ongoing project aims to document them all, along with the villas that were often their urban equals.

Consultancy varies from modest to larger schemes. Additional architectural photos can be found on Alastair's Flickr stream. Alastair has previously chaired the Forth & Borders Cases Panel of the Architectural Heritage Society of Scotland for two significant periods, and separately the Highlands & Islands Cases Panel. He tutors in Architectural History at the University of Edinburgh.
