Much of Tom and Martin's work has been renovation. Heythrop Park, which I like very much, is Tom's work. I shouldn't speak for Martin but having spent a certain amount of time with him, I think he might name Goodwood in Canada, which he built for Gordon Stollery of Angus Glen, as some of his best work (I haven't seen it).
Both of them are, I think, very talented architects. Since I spent time with him during the initial recreation of Askernish back in 2006', Martin has been high on my list of designers who would do something really good if the right project came along. And a number of good judges have told me that Tom's reworking of Skibo is top drawer.
