window ideas

Photo 1. Like the combination of wood and metal. Like the geometric design of the windows above. Note this has the windows above split from the doors below. This is a possibility for us - ie the big window could be split into two.
Photo 2. Example of double height room with sliding doors.
Photo 3. Concertina doors giving wide open feel. Like the doors.
Photo 4. Concertina doors with windows above like the wood split. Don't like the aluminum frames.
