The Brooklyn Cohousing Group found a building in Fort Greene to house its community in October, and is now moving forward with its development. The group has 25 member households so far — people who have paid $20,000 to $40,000 to help pay for the down payment for the site — and 25 associate households who have paid $500 and agreed to attend weekly meetings about the development. Members are expected to start moving in by 2010. The apartments will range from studios to four-bedrooms, and will sell for about market rate, but will have less square footage than similar units because residents can use common spaces for entertaining. There will also be no spare bedrooms as members will be able to use guest rooms for visitors.
