A builder has been given a suspended prison sentence after a roof collapse destroyed a home and injured three workers in Windsor.
Jack Savva, 70, was given a 13-month custodial sentence, suspended for two years, following the incident on 6 August 2020. Savva, of Wraysbury in Surrey, was carrying out a loft conversion on the property in Springfield Road, when the gable wall fell into the building after the roof was removed.
Two days before the incident, Savva had informed the home owner about work that was required on the chimney breast. He had told them it was incomplete as it had previously been removed from the first floor bathroom and would need to be propped. However, on the day itself, he instructed his workers to remove key supporting timbers and steels, resulting in the collapse of the brick gable wall which struck the workers and destroyed the first floor of the home, which was occupied at the time.
An investigation by the Health and Safety Executive (HSE) found Savva had failed to ensure the structure did not collapse while it was in a state of temporary weakness. He had not taken steps to address the unsupported chimney breast before dismantling the roof, which caused the brick gable to collapse into the work area. He also failed to take all practicable steps to prevent danger to any person while the building was in a temporary state of weakness.
One of the injured workers said: “I still suffer from nightmares of the day of the accident.
“I haven’t slept more than two hours a night over the last four years.”
HSE guidance about managing structural stability during alteration or dismantling advises about temporary bracing and propping being required – particularly if it is known or suspected of being weak. You can read more here: Structural stability during alteration, demolition and dismantling – HSE.
Jack Savva, of Friary Road, Wraysbury, Surrey, pleaded guilty to breaching Regulation 19(1) of the Construction (Design and Management) Regulations 2015. He was given a 13-month custodial sentence, suspended for two years and was ordered to pay £2,000 compensation to the home owner, at a hearing before Reading Crown Court on 17 September 2025.
HSE inspector Dominic Goacher said: “Although three men were seriously injured, it was lucky nobody was killed. In addition, the householder faced a bill of £200k to rebuild their house due to Jack Savva’s public liability insurance being invalid.
“This was a completely avoidable incident had he acted on his findings regarding the unsupported chimney breast and taken steps to support the gable wall before removing the roof components.
“Jack Savva should have taken precautions to protect people from the risk of collapse.”
This prosecution was brought by HSE enforcement lawyer Alan Hughes and supported by HSE Paralegal Officer Melissa Wardle.
