Walsingham House is an unlisted 1930s office building that John Robertson Architects is refurbishing and extending. The building is enviably located within the Trinity Square conservation area in the City of London. Originally designed by Howard Souster, its classical Portland stone facade is situated on the corner of Crutched Friars, Seething Lane and Pepys Street, with Grade I listed St Olave’s Church and the Grade II* listed Trinity Square directly adjacent.
The existing building is an irregular wedge shape comprising of ‘U’ shaped accommodation surrounding the core, spanning basement, ground and seven upper floors. JRA’s designs are transforming these spaces into flexible, Grade A office accommodation, suitable for modern occupiers. The original sloping roof will be removed to create a balanced façade and two new levels will be added, bringing the NIA up to 5,980m2. The three uppermost floors will boast private terraces for occupier use, providing panoramic views of some of London’s most notable landmarks. At ground level, JRA is creating a contemporary open plan reception and lobby featuring polished marble, metal panelling and timber. In addition, an inviting new entrance utilising wood and glass will be installed, in keeping with the historical exterior.
Sustainability has been a key consideration at Walsingham House. To improve the existing building’s offering, JRA is installing a new core that will increase energy efficiency and bring the building up to modern standards and regulations. The project is due to achieve BREEAM Excellent certification.
