When is a home addition not a home addition? When it is done as elegantly as the Lilyfield House in Sydney, Australia. Nobbs Radford Architects created this subtle modern extension, drawing inspiration from the humble original cottage, with its flanks clad in narrow wooden weatherboards, while still managing to convey a functional, standalone character. Starting from the original 19th-century weatherboard house, this modern addition evokes the ad-hoc add-on spirit embodied by decades of extensions. This addition nearly doubles the living space and maintains the spirit of the original pitched roof design without mimicking it.
