Architects ColladoCollins have announced that it has secured planning consent on a new 49 unit residential development, on behalf of Matterhorn Capital Ltd, at St Joseph’s College in Mill Hill London NW7. The development has now been acquired by THR Berkeley Group.
St. Joseph’s College, a substantial Grade II listed building, was built in the 1870s by St Joseph's Missionary Society, and was the first Catholic missionary society to be founded in England. The college in Mill Hill was first opened as a seminary and training center for priests training to go on missions abroad.
The main building sits on almost seven acres of land within the Mill Hill conservation area, and was developed in stages over its 140 year history, with one wing added in the 1930's and another in the 1950's.
The approved scheme includes the demolition of the late wings and their replacement with contemporary buildings of a consistent style. The main building and the new wings will house 49 apartments, 48 of which comprise one, two and three bedroom dwellings, ranging from 69 m² to 330 m².
The center piece of the redevelopment will be the conversion of the existing chapel into a four bedroom, 721 m² luxury apartment. It will feature open plan kitchen, dining and living areas occupying the apse, most of the central nave and the west cloister corridor. The existing lead roof of this corridor will be replaced by a glass roof to improve natural light and ventilation. The master bedroom will occupy a newly installed gallery on the north side of the nave, and will overlook the central living areas as well as giving residents a vantage point from which to view the chapel’s wealth of original features. The apartment will also feature four bathrooms, two of which are en-suite.
Roy Collado, Partner of ColladoCollins, said: “We’re delighted to have achieved consent for this fantastic local landmark. The building’s heritage, listed status and historic design presented us with a significant planning challenge, however this was overcome with a careful and sympathetic design that will form the basis for its redevelopment into a high end private residential scheme.”
ColladoCollins’ plans also detail how the development should be retrofitted to meet sustainability and energy standards. These include the provision of 182 m² of high efficiency mono-crystalline photovoltaic panel system, specially selected to be consistent with the external aesthetic of the Grade II listed building. These panels will help reduce the total CO2 emissions of the development by 7.2%.
Existing landscaping will be left intact and maintained and the existing agricultural buildings retained. In addition, 87 car parking spaces will be provided.
