In the thick of Clerkenwells variety of styles, scales and uses, Infinity House is an extraordinary family dwelling that has been miraculously carved out from a very constrained site. The detail design solution delivers a haven of privacy, facility and joy. The result is a design led rejuvenation project that substantially extends an 18th century Georgian Townhouse following the demolition of a 20th century industrial workshop that covered the original garden. The sanctuary and classic section of the Georgian townhouse has been seamlessly linked vertically and horizontally to new spaces. Soft reflections and floating details deliver magical transitions between old, new and nature. The structured planting of the sky gardens is visible from all the main spaces. Natural light is brought into all levels by extensive roof and floor glazing that lights the basement swimming pool, spa and ground floor. Reflections widen an elongated site, forming an illusion of infinite space. Lateral views, not provided by a terraced property, are developed with parallel and offset glazed materials applied to the party walls and emphasised with an internal and an external courtyard at the junction between the new and the old architectures. Infinity unfolds as light pours over, reflects within and is either recycled or absorbed by a variety of surfaces. There are numerous special moments, great spaces and details for which no amount of words can adequately explain the magic.
