King's Cross

Since 2008, we have worked with developer Argent on proposals for a site forming the linchpin of regeneration plans for the King’s Cross area in London. Masterplanned by architect Allies and Morrison and Porphyrios Architects, Pancras Square will feature six high-rise buildings and a central public space. We have subsequently delivered eight of the buildings on the estate as identified below.

The two hectare wedge of land, forming a new commercial district, is sandwiched between King’s Cross and St Pancras stations, with individual blocks designed by high-profile architects such as David Chipperfield, Eric Parry and Dimitri Porphyrios and Rab Bennetts.

Our involvement spans from civil engineering enabling works for the development – including extensive remediation of land contaminated by former gasworks – to the structural engineering of six of the landmark buildings. We also introduced a new pavilion building alongside Stanton Williams Architects, a three-storey structure overlooking the nearby Regent’s Canal. Initial work supported the outline planning application for the development and included a concept design for a 9 m deep basement across the whole site, to create a consistent base and structural grid for the buildings above.

We then worked with BAM Nuttall on the design and sequencing of the complex enabling works for the development, including decontamination works and excavation of the entire area to basement level and construction of a perimeter piled wall.

Detailed geotechnical analysis was also completed to show that excavations and subsequent construction works would not impact detrimentally on adjacent roads, utilities and nearby St Pancras Station.

The first building to be engineered by us was Five Pancras Square, the new 23,500 m² headquarters for Camden Council. This highly-complex design poses a number of technical challenges, including a new basement leisure centre complete with a swimming pool, requiring major load transfer structures. One Pancras Square, a nine-storey commercial building, featured cast-iron clad columns which created delicate interfaces with the structural concrete frame.

We were also structural engineers of the new large office building developed by BNP Paribas, Six Pancras Square, designed with long floor spans for maximum efficiency, and the speculative 13,500 m² office building designed by Allies and Morrison at Two Pancras Square. We conceived the design for the structure of the classic building at Three Pancras Square, and the high-quality student accommodation offered by Building T5, and most recently have been working closely with Eric Parry Architects on Four Pancras Square, a proposed commercial office block.
