Replacing two existing structures at 177-179 Piccadilly and 48-50 Jermyn Street, this new building establishes a distinctive presence on both streets, creates a more efficient working and living environment, and offers greatly improved levels of energy efficiency. The ground floor is devoted to retail, the first to fifth floors offer state-of-the-art flexible office accommodation and the sixth and seventh floors house a range of luxury apartments wrapped in a curved mansard roof.The portland stone facades offer an elegant contemporary interpretation of St James's traditional architectural character and feature a new public art work created by artist Pip Dickens. Grooves etched into the stone surface form a network of undulating ribbons which transform into brass-coloured metal strips as they pass before window openings; these shimmering threads lead the eye around the facade and bind the building together.The building employs a comprehensive package of energy efficiency measures which have achieved a BREEAM rating of 'Very Good' for the office accommodation, and an EcoHomes rating of 'Very Good' for the residential element.
