Perdita Martell v Grzegorz Roszkowski & Ors

16 April 2024
[2024] EWHC 840 (TCC)
High Court
Homeowner sued builders and engineers after a botched renovation. The builders used bad concrete, and the engineers didn't check their work. Both were found at fault. The engineers were also criticized for secretly taking money from the builders, which influenced their actions. The homeowner won, and the builders didn't get to claim their losses.

Key Facts

  • There was a dispute regarding the concrete specification (RC35) and waterproofing.
  • GSB used site-mixed concrete, contrary to the later issued Structural Specification.
  • MGA failed to monitor the work and notify Martell of the concrete defects.

Outcomes

Martell's claim against GSB and MGA for damages was partially successful.

GSB breached the contract by failing to use the correct specification concrete and failing to adequately design the waterproofing. MGA breached its duty by failing to monitor the work and advise on the need for specialist waterproofing advice; failure to disclose a conflict of interest.

GSB's counterclaim for lost profit was dismissed.

Martell's conduct did not constitute a repudiatory breach of contract.
