What is exactly meant by “atmosphere” when describing a room? Does it refer to space, decor, lighting, or color? While often referred to in design magazines, atmosphere, and, more critically, the elements that create it, have rarely been analyzed. Written by a leading designer and academic, <i>Interior Atmospheres</i>, the latest issue of AD, offers an in-depth examination of the subject of interior atmosphere in three parts: the speculative, the evocative, and the conversant. In the speculative section, a number of prominent designers, such as Claudio Lazzarini and Philip Stark, “speculate” on an interior, creating original interiors. The evocative section deals with ephemeral projects and the more transient qualities of space. The conversant section features interviews with prominent designers and thinkers, including architect and theorist Joel Saunders and architect Wolf Prix. Here is a fascinating look at one of design’s most compelling, yet elusive subjects for architects, interior designers, and students alike.
