In Stirlingshire, architect Bobby Halliday is taking on a huge development of bespoke homes on the site of an old farm steading in the shadow of Stirling Castle. As if juggling the ups and downs of such a huge build wasn't enough, he has to make sure that a house is ready for a client to move in to every three weeks.
