IKEA is working with BoKlok UK to be part of a revolution in housing in the UK. (26)BoKlok means "live smart" and is a project to provide affordable homes to people on average incomes. It aims to build small communities of BoKlok housing with at least 12 flats, 6 in each block.
    So will you soon be able to go to IKEA and drive away with a new home? Well, no, you won’t. BoKlok finds the land, gets permission to build, and the low-cost housing will only be available to people who can’t afford their own home. (27)The flats are built in a factory and delivered to the site—IKEA supplies the kitchens and the bathrooms. Buyers can then choose furniture and get advice on interior design from IKEA.
    So far, BoKlok has sold over 2, 000 homes—all of them in communities with shared facilities, such as gardens, to make neighbors socialize as much as possible.
    Houses of this type are called prefabs in the UK and the USA. And they’re not a new idea. In the early 20th century, the large American shop, Sear, offered prefabs. In Japan and the UK after World War 11, prefabs were a popular way of building new houses quickly and cheaply.
    Nowadays the price of housing in many countries makes it very difficult for a lot of people to buy or even rent. Prefabs offer home-buyers modern, quality homes which are designed by architects and are often very environmentally efficient. (29)In the USA the popularity of prefabs is growing rapidly with young people who want a 21st century-designed house.
