This question is part of why I like Kington and Cleeve Cloud so much. The courses are actually quite intimate in length and design ambition, especially Kington. However, the properties are huge scale, especially Cleeve Cloud. A course like Cleeve Cloud would never be conceived today.
I think its quite difficult to build intimate scale on an intimate property with all the fuss over safety, thus the overuse of trees. I fear that for most, intimate means tree lined, secluded. I think of intimate as a short walk using minimal land, but the best of these still affords views, even if only internal, and a sense of the property being larger than it truly is. There are reasons why so many classic designs are still cherished despite the advanvement of technology.
All that said, it would be churlish to criticize some of these modern classics because of the use of scale when
the property is begging for this kind of use and so many fine products are the result. There is room in the world for all sorts and styles of courses.
