At first glance, the front facade of the Villa LL in Casablanca, Morocco, looks a bit forbidding, with its thin, blank wall of white plaster-covered concrete. But look again, and you see that the wall curves in on either side of the front door, which is topped by an asymmetrical canopy with curved corners. And curved walls extend past each end of the screenlike facade. They hint at the flowing spaces, and more curves, that are inside the just over 3,100-square-foot house, designed by Mohamed Amine Siana, a Record Design Vanguard architect in 2016. The client is an artist, for whom security and privacy are important, as well as what Siana calls “sensual lines,” adding that the person wanted the house to be “protective but not too enclosed.”
