Small house movement
In the United States the average size of new single family homes grew from 1,780 square feet (165 m2) in 1978 to 2,479 square feet (230.3 m2) in 2007, despite a decrease in the size of the average family. Reasons for this include increased material wealth and prestige.
The small house movement is a return to houses less than 1,000 square feet, some as small as 80 square feet. Sarah Susanka has been credited with starting the recent countermovement toward smaller houses when she published The Not So Big House in 1997. Earlier pioneers include Lloyd Kahn, author of Shelter in 1973 and Lester R. Walker, author of Tiny Tiny Houses: or How to Get Away From It All in 1987.
Tiny houses on wheels were popularized by Jay Shafer and Gregory Johnson, who together founded the Small House Society in 2002. Shafer designed a tiny house for Johnson to live in, and then Shafer went on to offer the first plans for tiny houses on wheels, initially founding Tumbleweed Tiny House Company, and then Four Lights Houses.
In the USA in 2005, after Hurricane Katrina, Marianne Cusato developed the Katrina Cottages that start at 308 square feet (28.6 m2) as an alternative to FEMA trailers. Though these were created to provide a pleasant solution to a disaster zone, Cusato received wider interest in her design from developers of resorts, for example.
With the financial crisis of 2007–2010 the small house movement attracted more attention as it offers housing that is more affordable in acquisition and maintenance and ecologically friendly. Overall, however, it represents a very small part of real estate transactions. Thus only 1% of home buyers acquire houses of 1,000 square feet or less. Small houses are also used as additions on the property (accessory dwelling units or ADUs) for aging relatives or returning children, as a home office, or as a guest house. Typical costs are about $20–50,000 as of 2012.
Interest in very small homes has been revived in other countries: in Japan, where space is at a premium, Takaharu Tezuka has built the House to Catch the Sky in Tokyo, a 925-square-foot (85.9 m2) home for four; in Barcelona, Spain, Eva Prats and Ricardo Flores presented 300-square-foot (28 m2) House in a Suitcase; in England, Abito created intelligent living spaces apartments of 353 square feet (32.8 m2) in Manchester; and the Micro Compact Home (M-CH) is a high end small house developed by the British architect Richard Horton and the Technical University of Munich. The M-CH is a 76-square-foot (7.1 m2) cube, designed for 1–2 persons, and has functional spaces for sleeping, working/dining, cooking, and hygiene.
Small and tiny houses have received increasing media coverage  including a television show, Tiny House Nation, coming July 7, 2014. The possibility of building one's own home has fueled the movement, particularly for tiny houses on wheels. Tiny houses on wheels are similar to RVs, but built to last as long as traditional homes. However, unlike traditional homes, tiny houses on wheels do not require building permits. This increase in popularity of tiny houses, and particularly the rapid increase in the number of both amateur and professional builders, has led to concerns regarding safety among tiny house professionals. In 2013, a Tiny House Business Alliance was formed  to address ethical and safety issues. In addition, workshops are held nationwide by various professionals in order to teach tiny house enthusiasts to build their own homes safely.
Pros and cons
Larger homes are more costly in terms of building, taxes, heating, maintenance and repair. In addition to costing less, small houses may encourage a less cluttered and complicated life and reduced ecological impact for their residents. The typical size of a small home seldom exceeds 500 square feet (46 m2). The typical tiny house on wheels is typically less than 8 ft by 20 ft, with livable space 120 square feet or less, for ease of towing and to except it from the need for a building permit.
Small houses may emphasize design over size, utilize dual purpose features and multi-functional furniture, and incorporate technological advances of space saving equipment and appliances. Vertical space optimization is also a common feature of small houses and apartments.
As small houses may be attractive as second homes, their increased utilization may lead to development of more land. People interested in building a small home can encounter institutional “discrimination” when building codes require minimum size well above the size of a small home. Also, neighbors may be hostile because they are afraid of a threat to their property values. However, this concern may be baseless as there is evidence that they actually increase property values through increases in density. There has also been opposition based on this fact, due to concerns about increased taxes.
