A central glazed courtyard, designed for year-round use, will form the heart of the development, intended to support seminars, events and informal working.Glyn Emrys, director of Emrys Architects, said: This is a unique site which requires a series of bold yet sympathetic solutions to deliver a leading office and retail space in the heart of Bloomsbury.A new Alfred Place frontage, constructed from glazed brick, will link two of the existing buildings and establish a unified entrance.Originally used for retail and manufacturing related to the furniture trade, the buildings have presented several challenges, including changes in level and ageing fabric. The retrofit strategy includes new circulation cores and ramps to improve step-free access between different parts of the newly consolidated building.Terrace with reinstated cupolaSource: Emrys ArchitectsView from Tottenham Court Rd and Windmill St looking North EastSource: Emrys ArchitectsNew combined entranceSource: Emrys ArchitectsView from Alfred PlaceSource: Emrys Architects1/4show captionCorridors and stairways will be widened, and meeting rooms reconfigured to allow wheelchair turning space.An additional fourth storey is proposed at roof level, set back from the main faade to reduce visual impact, and will house further office space and landscaped terraces.
