Windows day 2

I'm at the point in the housebuilding process where I can say, "I wish we had used the past year of waiting to educate ourselves better." Somehow, I really wish we weren't at this impasse right now. We should have gone through this already.
As I said in yesterday's post, Mr. B has already sent out requests for estimates on windows. These requests are for full wood windows with security type shutters and window grills.
Only now, that we already have a bunch of requests out there, we've decided to get busy looking into windows. Today, we went to the showroom of a window producer in Stuttgart. On many, many levels, purchasing direct from them would be really cool. We had another lesson in the options- plastic, plastic covered with aluminum/ plastic, full wood, or aluminum/wood. Oy!
I don't love the thought of plastic. Really. Joern seems to like full wood the best. To me, the biggest problem with full wood is that you have to paint the weather side with wood every 2 years. While Joern is a great guy, house repairs aren't high on his list. I just get the feeling if you install full wood windows, that you need to be someone who loves to repair their house. Not Joern.
Obviously, to me the best option would be aluminum exterior, and wood interior. The only problem with this of course, is the fact that you could buy a considerable car with the price difference between plastic and aluminum / wood, with full wood somewhere in the middle.
And window grills? Huh? Do we need them? My argument for them is that they provide some visual interest to the outside of the house. I find German houses pretty square and boring. When you add window grills, it spruces up the look and here especially, it would help the house to stand out a bit.
The other problem: you have to know the color of the house when you order the windows. Why? Because the color you order for the windows needs to match the house and the roof. Sigh.
I don't know what to do. To make matters worse, I feel like my mind is crashing with the color of the house. I originally wanted white with a black roof. Then we chose roof tiles the week before we left, they were not normal German roof tiles, so I liked them. Unfortunately, I didn't realize what Mr. B said until we got back from our trip, that this style only comes in a dark gray. Nooooo!!! All houses lately are built here with white exteriors with a gray roof and gray trim. This is how you end up with an "oh that's so 2010" house. I am not a trendy girl. Now, Joern told me today, he wouldn't mind beige as an exterior color. Last week, he shot me down when I suggested a beige house. Yes, if we don't like the exterior, we can paint, but if we don't like the colors of the windows, depending on the material, it isn't so easy to change. Aaahhh!
