Do you have any key texts for architectural theory & practice that you'd recommend to a non-expert?
Sorry for the delay! Here are 10 suggestions, in no particular order:
Rural Studio: Samuel Mockbee and the Architecture of Decency - Dean (Mockbee's work in many ways can be interpreted as a fundamental critique to the state of the architectural/design industry - instead of flashy facades and overtly complex forms and styles you will instead find here a collection of buildings constructed with a high degree of care for the sole purpose of providing healthy, affordable, practical, and sustainable spaces)
Thinking Architecture - Peter Zumthor (this is a collection of essays by the architect recording his opinions on the effects of well designed spaces and why they are meaningful)
The Eyes of the Skin - Juhani Pallasmaa (establishes that vision is hegemonic in architectural design therefore the architectural community must further address the other senses)
Questions of Perception: Phenomenology of Architecture - Steven Holl (addresses pretty much what the title says)
Learning from Las Vegas - Venturi, Brown (las vegas as a case study of the rise of signs in the 20th century)
In Praise of Shadows - Tanizaki (a non-designer discusses the subtleties and intimate nature of traditional japanese design)
Studies in Tectonic Culture: The Poetics of Construction in 19th and 20th Century Architecture - Frampton (I've yet to read this but it's a key text for one of my closest friends - you can't talk about architecture seriously until you understand tectonics! this is actually the next book I intend to read)
Life and Death of Great American Cities - Jane Jacobs (the key text I would suggest for addressing the design of cities and communities)
Architecture of Happiness - Botton (I also haven't read this but many of my friends recommend it as a great introductory text to architecture and the senses)
The Image of the City - Lynch (a fascinating case study conducted in the 1960s recording how the citizens of Los Angeles, Jersey City, and Boston have developed a visual language to navigate and 'read' their cities, the principles derived from this study are applicable to all cities)
