Some mostly recent books on houses, some posh, some not.
The Green House
Authors Alanna Stang and Christopher Hawthorne argue that green design is not just ecologically responsible but also high style— "camera ready." They make a good case, using projects like Georg Driendl's Solar Tube, in Vienna, Brian MacKay-Lyons's Howard House, in Nova Scotia, and Lahz Nimmo's Casuarina Beach House, in northern New South Wales.
Prefab Modern
A well illustrated and gracefully written survey by Jill Herbers showcasing some designers who are making prefab both affordable and stylish. Besides the projects listed elsewhere on this site, these include Adam Kalkin, Jennifer Siegal, Michelle Kaufmann, and Resolution: 4 Architecture
The Very Small Home
The subtitle says it: "Japanese Ideas for Living Well in Limited Space." Author Azby Brown has compiled a collection of houses most of which are so diminutive they'd fit into the master bath of a McMansion. These include Tadao Ando's austere 4 x 4 House, just 243 s.f., and Architecture Lab's White Box House, a comparatively roomy 559 s.f.
David Adjaye Houses
A handsome monograph featuring a dozen of the houses that have made Adjaye a rising star of London architecture. These include Elektra House and Dirty House, plus the residences he's designed for Ewan McGregor and Chris Ofili.
