Also Gilze-Rijen is not probable. As are Bergen, Deelen, Venlo, Volkel, Eindhoven, Havelte, Twente and Schiphol.
These kind of "open" shelters are not known in the Netherlands.
The only possible airfield with this kind of shelters was De Vlijt at Texel island. But that was not an Nachtjagd airfield.
Maybe this picture was taken at an airfield in Schleswig-Holstein?
