Waldeck Road in Ealing, located halfway between Heathrow airport and the centre of the city, is an archetypal middle-class London residential street: two stories plus an attic, brick façades featuring white timber, all of it infused with the spirit of the Victorian Age. And suddenly, a sober building consisting of grey brick cubes with large black windows and anthracite metalwork – the Tree House – forms a stark counterpoint to the surroundings.
