Forty-two houses are profiled in this book, ranging in size from 6.5 sq. m./ 70 sq. ft. to 294 sq. m./3,165 sq. ft. More than half the houses are over 120 sq. m./1,300 sq. ft., so they aren't necessarily small. They are architect designed in the minimalist style, mostly boxes with flat roofs, but a few dare to step out of the box with gabled or shed or v-shaped roofs. There are houses for every budget, from low cost prefabs to luxurious, custom built houses.
Each profile gives an almost too brief description of the house followed by icons with reasons why it is an eco house, floor plans and/or elevations, and color pictures of the interiors and exteriors with views of breathtakingly beautiful landscapes. Here are a few examples of the variety of houses in this book:
The Joshua Tree house is a gabled roof prefab, on wheels for transport, with two bedrooms and a long, skinny bathroom with a toilet and sink on each end and a shower in the middle, all in a tiny 36 sq. m./387.5 sq. ft. space.
The Float houses are low cost prefabs in New Orleans for people who lost their homes during Hurricane Katrina. They are narrow, shot gun houses that resemble mobile homes but they have unusual design innovations. They are built to withstand another hurricane and are on a chassis that will float like a raft during a flood. The roof is v-shaped with a groove to capture rain water.
The Casa Pulmo house is a two story house with an outdoor wheelchair ramp connecting the levels.
Half of the house in Geres, Portugal, featured on the cover, juts out over a cliff. It has a low environmental impact because part of it hovers in mid air!
There are houses in Norway and Iceland specially designed to withstand a sub-arctic winter. The landscapes had no trees and little vegetation.
