[2026] EWHC 312 (TCC)
In the Technology and Construction Court
Before Recorder Singer KC sitting as a Judge of the TCC
Judgment delivered 16 February 2026
The facts
Baltimore was the owner of a mixed-use development near Crossharbour DLR station on the Isle of Dogs that had been developed by Ballymore and completed during 2010. Ballymore provided Baltimore with a collateral warranty deed dated 7 January 2013. During July 2023, the roof of a nursery forming part of the Baltimore Wharf development collapsed. Relying upon the collateral warranty, in May 2024, Baltimore commenced proceedings against Ballymore claiming damages in excess of £2 million. Ballymore denied liability and during July 2024 commenced a Part 20 claim against its structural design consultant, WSP UK Ltd, where it was alleged that the nursery roof had collapsed because of the failure of the connection between the roof steel beams and the reinforced concrete frame.
