The initial assumption for this City of London tower, opposite Liverpool Street Station, was that it would be demolished and rebuilt. Fletcher Priest working with the client, Landsec, revealed that the concrete frame and foundations had capacity for six additional storeys within the height restriction of St Paul’s viewing corridor, increasing the usable area by over 40%. Retention of the building frame avoided demolition costs, site clearance and the construction of a new structural frame. It also resulted in a shorter contract period on site and we made significant energy savings overall. Our design replaces the existing pre-cast panels with a new lightweight high performance cladding system of floor to ceiling glass which optimises daylight and views out across the city. We used new technological advanced, efficient lift cars in existing shafts maintaining the original core size even with the extra storeys added.

The building sits next to the Grade I listed St Botolph’s Church. The adjacent public gardens have been extended around the base of the tower providing a new landscaped public space overlooked by reception and new restaurants on the ground floor. Our approach delivered a building one year ahead of a conventional new-build programme, with an increase in net floor area and a BREEAM Excellent environmental rating.
