This mixed use development, comprising of two ground floor commercial units, seven residential flats and a standalone studio house, is built within the curtilage of the Neckinger Mills site, a Grade II Listed 19th Century former tannery mill. The building is approached via a gated cobbled courtyard providing access and parking to the building and existing ‘warehouse’ apartments and commercial studios. The massing is stepped backed at each floor creating terraces for the apartments and reducing the visual impact on the existing tenants preventing overlooking. The large double glazed aluminium windows, with subdivisions, mirror the existing cast iron Victorian warehouse windows; rustic dark grey bricks, render and aluminium mesh cladding accentuate the new massing. The apartments are designed to Level 4 of the Code for Sustainable Homes and include ventilation heat recovery units along with high levels of thermal insulation, acoustic attenuation and communal cycle parking. The commercial offices comply with ‘Excellent’ in the BREEAM sustainability ratings.
