Jeroen,
thanks for your reply. I had seen those titles on amazon, but wasn't sure if these titles had any golf course architecture elements in them. Judging from Paul's answer they probably do not have anything on that subject. Paul do you know if Penninck ever wrote articles in British Golf Magazine's?
The courses that Penninck did in NL are: Broekpolder, Edese, Geijsteren, Gelpenberg, de Haar, Kleiburg, de Koepel, Lauswolt, Noord Nederlandse, Noordwijk, Oude Maas, Sallandsche, Wouwse Plantage en Zeegersloot.
I've played only three of Penninck's courses sofar: Edese, Hooge Kleij and Noordwijk (although it seems from the Noordwijk's history book De Geschiedenis van de Nieuwe Baan (The History of the new Course) by Paul de Jong, that Penninck did not play a real meaningful role. The real design seems to have been done by de Jongh, a member of the club, aided by an inexperienced shaper. The book is a very interesting read on how the course was routed and designed, unfortunately it's in Dutch).
Of these both Edese and Hooge Kleij need work, be it on different areas. Edese was pieced together over time (Dudok van Heel designed the new holes) and therefore lacks consistency in style (the big give away on that point are the bunkers). De Hooge Kleij was built on a very low budget, which is visible by the fact that the green complexes are rather simple. The course needs some more interesting shaping around the green complexes and some better bunkering.
Noordwijk is a good course, but has two problems. First it is totally overwatered, so it's too green and too soft. Second problem is harder to change, and that is that it only has one good links par 3 (hole 17). This is a shame since the course lies in virtually perfect links land....
In the near future I will visit/ play Broekpolder (I played it 20 years ago, did not like it very much, very much Polder golf, but seems to have grown in/ improved a lot) de Koepel and Wouwse Plantage.
