Walsingham House is an ex-commercial building of eight storeys above ground and a basement level. It is located in Trinity Square amidst one of London’s most popular tourist areas; flanked by the Tower of London and Tower Bridge, it falls beneath the imposing shadows cast by The Shard across the river and the Walkie Talkie building just around the corner.
Located within the Trinity Square Conservation Area, Walsingham House is being transformed into modern and much-needed office space totalling 6,000m2 in the heart of the City of London.
