Now that the building permit is issued, I have 2 significant things I'm working on.
1) Theater - We just received the designs from Dennis Erskine. I have to redesign downstairs a little to create a separate entrance to our dedicated gym & incorporate the theater design that Dennis did for us.
2) We received a price increase from our PVC/Vinyl window supplier so we're re-evaluating the decision to go with Vinyl windows.
Vinyl windows are superior from an insulation perspective to aluminum, like aluminum they don't require maintenance, unfortunately they are somewhat looked down upon here in Australia and our builder and others have commented that they wouldn't do good things to our property values.
We've narrowed down the decision to timber (cedar), or powder coated aluminum. Cedar is a much better insulator than aluminum. Aluminum is a good conductor and used to make things like cookware, hence it is less energy efficient. The upside of powder coated aluminum is that it never needs any maintenance. Once you put it in, there's no repainting involved. Cedar I'll need to re-stain every couple of years. It's a tough decision, but I'm leaning toward the warm look of the cedar. Cedar is a beautiful timber.
