Piet Hein Eek writes:
"It sometimes happens that you are asked to produce something you have wanted to do for some time. A customer called and asked if we could build a log shack in is field, one that would be large enough to sit in and write inside.....The windows and shutters are what really make the difference. The sliding windows are fitted into specially designed frames, although "specially designed" is somewhat of an exaggeration for the simple plastic and steel profiles."
