PROJECT DESCRIPTION

The re-purposing of the gasworks infrastructure at King’s Cross: the distinctive ‘Triplet’ of 138 year old gasholder guide frames were restored and formed the basis for a unique new residential offering, with three cylindrical concrete buildings positioned inside. An exhilarating blend of contemporary architecture with Victorian infrastructure.

Judge's comment:

Working within the constraints of these three 140 year old cast and wrought iron gasholder guide frames, the engineers have seemingly developed a structural solution that  onours and celebrates the heritage value of these historical structures.

The guide frames themselves had previously been disassembled in 2001 and stored nearby. Extensive study was required to ascertain their structural viability, as numerous original connections had been cut during the disassembly process. The iconic nature of these frames pushed the engineers to consider sensitive restoration approaches to minimise changes. The original frames did not include cross-bracing thanks to the stability achieved at the interface zone where the three frames meet. This became the central feature for the development, which included delicate new footbridges weaving between the guide frames.

The judges were pleased to see the frames restored and given front and centre attention in this new development.
