Cladding specialist Harley Facades’ “project designer” for the Grenfell Tower refurbishment has told the probe into 2017’s fire disaster that he was merely a freelance drafting service charged with turning architect Studio E’s drawings into fabrication versions.

Kevin Lamb told the Grenfell Tower Inquiry that he had agreed to do around 41 days of work on the project for Harley because it did not have the in-house capacity to translate Studio E’s work into plans that were ready for construction.
