I selected this today for my house. But I felt it deserved it's own thread.
With PD we get a fully glazed laundry door. I upgraded to one of these. Absolutely sensational. It's double glazed and has a blind inside the glazing that is operated by magnets. The slats can be adjusted to let in light, or the blind can be raised entirely just like a normal venetian.

It will only be a few hundred extra in upgrade cost apparently. I checked with my CSC last week. It's from Corinthian and I think it is absolutely sensational and worth every penny. Our laundry will face west and would need some type of covering on the glass door so now it's all in one.
It also comes in a half glazed model.
