Designed by American architect Wallace E. Cunningham, the "Razor House" is famous around the world for having inspired the villa of Marvel hero Tony Stark, appearing in the Iron Man 3 movie. The property is perched on a reef in La Jolla, near San Diego, California. Featuring an ultra-modern design and large windows, the villa enjoys stunning views of the Pacific Ocean. Inside are a living room on a circular plan, four bedrooms, two kitchens, a cinema room, a billiard room and a library. The exterior includes a heated infinity pool, a health club, rooftop terrace, kitchen and garage. The property includes a detached guest house with two bedrooms. Built in 2007, almost entirely of glass, steel and concrete, the residence of more than one thousand square meters was put up for sale a year ago for $30 million. Singer Alicia Keys concluded the purchase for 20.8 million dollars, about 18.8 million Euros, making this sale the most expensive of the year in the exclusive La Jolla area.
