BuckleyGrayYeoman has won planning for this rooftop pavilion on an office building next to the Gherkin in central London
The two-storey rooftop extension to 107-112 Leadenhall Street will add more than 1,000m² of office space to the existing building.
The pavilion will be clad in stone and will have a sedum roof.
The scheme will be overlooked by a clutch of surrounding tall buildings, including Foster + Partners’ Gherkin and Rogers Stirk Harbour + Partners’ Cheesegrater, due to complete later this year.
The architect’s view
‘London is going through a major phase of building tall and that presents some really interesting opportunities for architecture. With tall buildings creating new vistas across the city, roofs have become a new layer of London’s landscape. Our extension of 107-112 Leadenhall Street addresses the quality of this new space, adding prestige to the often forgotten ‘fifth elevation’ of the building.
‘The design of the pavilion will create a unique location nestled in the heart of the City tall buildings cluster, with light-filled interior spaces and outdoor amenity for future occupiers of the new floors. Impressive views over the surrounding cityscape will be maximised by a series of setbacks that create accessible terraces enclosed by clear glass balustrades.
‘The pavilion’s continuous, colonnaded facade will be clad in reconstituted stone to create a legible and concise form that blends harmoniously with the existing eight storeys below. Roofscape views from neighbouring buildings will be greatly enhanced by the pavilion, which will add visual interest to this newly prominent site, highly visible from the neighbouring towers.
‘A sedum roof, articulated with linear skylights tops the pavilion off, providing a visually uniform surface while meeting the City of London’s aspiration to encourage biodiversity in the centre of London.’
