A late 1990s New Urbanist quarter in Stockholm that I think pretty much suits the city. It's speaking the traditional language of the city's fabric, but still adds something fresh. Lovely, livable.
Sankt Eriksområdet is a good example how to build urban new quarters, yet sustainable and sticking to what makes a place, traditional elements. Block perimeters are important - don't build satellite housing estate like blocks or rowhouses!
Rosemary Beach, a New Urbanist community in Florida.
It was started in 1995 by Duany Plater Zyberk & Company, who also planned Seaside, Florida.
It's a highly demanded residential location and tourist spot today.
