Modular Penthouse, Wandsworth High Street

Generous glazed areas and therefore naturally lit apartments with fine views out are an extremely desirable part of the modern home. A common misconception and criticism of prefabricated modules is that they offer little opportunity for large glazed facades. Atelier One have proved this is clearly not the case on previous projects such as the rooftop extension to The White Cube Gallery in Hoxton Square and on their work on the Piper Building, Fulham. The key to glazing prefabricated modules is to provide enough stiffness to eliminate movement when the modules are transported.

This new two-storey penthouse is located above an existing four-storey building on Wandsworth High Street, London, within a Conservation Area.

The 2,400 sq ft apartment for private clients was pre-fabricated in Slovenia, and transported as five separate 12.0m long modules to London, where they were craned into position over a 2-3 day period, before connection to the existing services and stairwell. The steel framed structure minimised the load on the existing building and afforded strength during transportation and lifting. A modular construction route was chosen primarily to avoid disruption, noise, and dust pollution to the clients who occupied the top floor of the building. In addition, a conventional construction route with scaffolding and temporary shelter on this constrained site proved particularly difficult and costly.
