The pavilion sits perpendicular to the 19th-century building in the English countryside — creating a sheltered courtyard in the divide.“Given that the pool house was going to be in its own building,” de Cárdenas explains, “the main thing was to make it feel like a destination, something quite distinct from the main house, but that complement its surroundings.” Built from brick and copper, the building was designed to harmonize with the existing home whilst adding a contemporary touch. The space is experiential and refined — but designed with the clients, and their children, in mind. The inside of the ceiling has been lined with ridged fiberglass panels that are an architectural feature, designed for their changing quality in light and their noise dampening ability. The walls and floors around the pool have been crafted from Botticino marble, and then scored and treated with an anti-slip finish to avoid accidents. Indeed, de Cárdenas’ attention to detail is evident in every finish: The sheets of Azul Macula quartzite that line the pool were book-matched on site to ensure that there was a consistency of grain, and the shape of the hot-tub is mimicked by the skylight above it and the curved room that it sits at the center of.
