Nextroom, which I may have written about before, was started by the Swiss architect Juerg Meister in 1996. “At nextroom's core lies the databank, with thousands of buildings, images and texts, as selected by independent institutions. nextroom acts as the central interface for all this information. This provides us with a matrix of information, the quality and density of which are without equal.” I'll say. I go to the single-family homes tab on the list of building types, which is under the larger heading of Index Listings where you can also peruse projects by the name of people involved with the project, location, and chronology.
Then, there's World-Architects which gives you access to hundreds of mini portfolios of architects all over the globe, links to their own websites, and lots of other links to related businesses, events, publications, resources and even jobs.
Got more time to spare? There's Archinform which is a database for international architecture, originally emerging from records of interesting building projects from architecture students. It has become the largest online-database about worldwide architects and buildings from past to present. There is information on more than 18,000 built and unrealized projects from various architects and planners. The architecture of the 20th century is the main theme of this database. You can search for projects by architect, town or keyword or by using a query form. For most entries you get the name, address, keywords and information about further literature. Some entries include images, comments, links to other Websites or internal links.
Then, if your eyes have not yet melted from their sockets, there's always Danda's links list and gallery.
OK - that'll keep you busy for a while! – GF
