A geometric home slips discreetly into this London neighbourhood

No Londoner, when faced with an empty plot at the end of their historic Victorian mews, has ever said, “What we need next door is a 6,000-square-foot house with an indoor pool.”

And yet, voilà.

How did it happen? How did a hefty brick house with a 15-foot basement end up on this corner site blocks from Bloomsbury Square and the British Museum? The long answer, says the structure’s Canadian-born, London-based architect Jamie Fobert, is this: “The neighbours were upset about a proposed apartment block, so when this came along, they embraced it.”
