In addition to its sleek, minimalist design, this West London private residence dubbed Number 23 (based on its street address) designed by and for Matt White of MATT Architecture, is very playful. From the camouflaged front door with a very cool cut-out 23 and the humorous “hello” right above it, to the large single window jutting out of the façade with its electronically ‘switchable’ glazing—an LED technology that creates opacity for privacy with a mere flick of a switch—to the climbing wall and little messages such as “boo” in neon inside the bar cabinet and the “I don’t have OCD” mugs in the kitchen, these guys definitely had fun working on this home. Plus, the simple elevation conceals a house that is 30% bigger than its neighbors, despite occupying a 20% smaller plot and also includes various concealed technologies that dramatically reduce the energy consumption and running costs for the family. Magic. Humor, trickery, energy efficiency, and style…what more could a person ask for in a design?
