The document discusses the key spaces needed in an architect's office, including a reception area, conference room, studio, chief architect's room, free space, records and storage, and owner's room. It provides the minimum recommended room sizes for each space. The reception area is meant to make a good first impression on clients and should be arranged to showcase the firm's design style. The conference room is for meetings and also serves as a waiting area, with large windows to allow natural light. The chief architect reviews plans and designs there before presenting to clients.
