This is a building I saw first on Archidose.  Since the website project description is in Dutch, it’s hard to get specific information on this building, but I’ll share what I’ve been able to get translated.  Urban Cactus is a project of the Rotterdam-based architectural office UCX Architects, founded by Ben Huygen + Jasper Jagers.  It will have 98 residential units on 19 floors, and because the project abuts the harbor, the architects chose to give the building a more green, natural feel (rather than the urban feel common to neighboring architecture).  I’m thinking that this layout provides an interesting mixture of sunlight + shade with the perfect amount of green space that is usually lacking in most vertical high-rise buildings.
