Why it's Wildland
5.7Charles and Maggie Jencks turned their West London home into an exuberant architectural argument: part house, part museum, and part puzzle. Its 52-step circular staircase tracks the weeks of the solar year, while a kitchen frieze swaps classical ornament for projecting salad spoons. Look closely: here, decoration is also a trail of ideas.
The Cosmic House earns its place for the way it makes a domestic interior feel like an architectural treasure hunt. Rather than a conventional museum sequence, its rooms, symbols and playful details invite visitors to follow one idea into another—an unusually immersive encounter with postmodern design in a residential London street.
