Pott Architects created this unique, triangle-shaped house in the Lichterfelde district of Berlin, Germany. From the outside the home appears to be a single volume, but when inside, rooms are beautifully divided into multiple levels and spaces. Found on Freshome
I love the staircase that flows down the slope inside the house, I imagine most architects would be tempted to let go of such an obvious split-level approach.
I found their work a while back and I was also impressed by their House L:

It’s a slightly different approach but still incorporates the firm’s design language, although it’s a shame that they’ve included so few shots of the lower levels of the interior.
