“The 45-acre Peacock Farm, built from 1952 to 1958, shared the subdivision tradition of taking its name from the previous identity of the site; peacocks really had been raised there. But it was far from traditional. Floor plans were open, wide expanses of glass substituted for walls, roofs were asymmetrical and only slightly sloped, and basements were raised higher than in most houses, allowing in more light and elevating their role.”
