30 St Mary Axe

A view from inside the Gherkin

Project team

Developer: Swiss Re
Architect: Foster + Partners
Contractor: Skanska
Structural Consultant: Arup


Technically complex and visually striking, the building is unlike any other and set the trend for giving buildings nicknames based upon their shape. The building is 40 storeys high and serves as a multi-tenanted office space and a restaurant. Complex features include the diagrid structure, six storey atria spiralling up the building to form 'villages' and a double skin ventilated facade. This was one of the first tall buildings of its kind in London and one of the most well known.

Our role

From an early stage, we assisted the design team with the very complex design, including early input into structural, fire, drainage and mechanical and electrical engineering. Our surveyors inspected the works on site from commencement to completion, giving the client and ourselves the comfort that the regulations have been completely satisfied.

We have also been involved in numerous fit out works at 30 St Mary Axe, including the restaurant under the large domed roof at the top of the building.

If you are contemplating taking office space at 30 St Mary Axe or completing a similar commercial development, we are happy to assist you with any Building Regulation queries you may have and offer pre-application advice. Please call 020 7332 1000 or email the District Surveyor's Office.
