Niall,
To the best of my knowledge, Burning Tree was originally an Alison design (under the banner of Colt, Alison, Mackenzie). Some have improperly credited it a Mackenzie. I believe, and I might be mistaken, it was constructed by the Flynn & Toomey Construction Company.
Several of the holes west of the clubhouse (10,11,12,13,14) were impacted by the Beltway.
Arthur Hills did work there at some point in the past 10-20 years. Obviously, it is a lot different now. It's a club with a great atmosphere and a lot of history. The historic aerials website goes back to 1949 and shows more bunkers in existence than today, as well as long bunkering on one side of the fairway on many holes.
(Off architecture, but especially fun is looking at the photos from the early 1960s and the slides of the Beltway in progress of being built)
