Agreed": I too love big windows and hallways, my house has large windows and large glass doors across the whole back so I can see the backyard gardens from most rooms. They are all tinted to stop the sun from penetrating. The house is fully insulated for the climate here in Queensland. large hallways give an opulent feeling to a house.
Your house sounds very pretty. The laundry room at my house also counts as my mother's tea/sun room. It over looks our little back yard which because of all the trees, I've nicknamed Indinera Glade since I played LPII when I was little.
