Brandon is a 23-year-old software engineer who is saving over 90% of his income by living in the back of a 16' box truck parked at his work. He answers questions and documents his experiences on his blog. Instead of an apartment or a house, less than one hundred square feet may be all you need.
Christian Schallert transformed his tiny 258 square feet apartment into a much more usable space by creating a vast wall of clickable furniture, and a spring-loaded door swings.
With the economic downturn and a steady downward trend in family sizes, the end of the McMansion could be at hand. Some people are living in and building tiny houses (previously) to decrease their impact on the environment, while others can't afford more (or wish to own something small instead of paying off something big). Sergio Santos saw his small budget and limited space as a challenge (gallery), maximizing his 77 square foot space as a bedroom, office, and mini-kitchen. Claire Wolf lists the four pieces of living small: building, gadgeting, decorating, and coping. If these spaces are too small for you, Dan Maginn suggest 900 square feet for a 2 bed, 2 bath house, and outlines how to design your own small home (his tips: think "events" more than "rooms," and don't forget the cupboards and water heater closet).
Dirk Dieter, an industrial and exhibit designer, paid $101,000 in 1999 for a 250-square-foot house built on a triangular lot at the end of a dead-end street in Pacifica. Built in 1954, the little house was probably a warming shed for local fishermen, but Dieter's modest yet dramatic renovation has transformed the house into a marvel of space-saving design, inspired him to formulate strategies and design furniture for streamlined living, and brought a recent appraisal of $375,000.
