Administrators from EY took control of the fit-out contractor in February and have now revealed the scale of the company’s debts.
A statement of affairs shows trade creditors were owed at least £20.9m with hundreds of firms left holding unpaid bills.
Styles & Wood also owed £49m to its lenders leaving nothing for unsecured trade creditors.
EY said Styles & Wood was sunk by significant losses in its projects division.
The biggest loss of £12m on a single project was at the India Buildings in Liverpool where its £38m contract was terminated last year following a series of delays.
Styles & Wood was bought in 2018 for £42.5m by investment vehicle Central Square Holdings and became a leading division in the rebranded Extentia Group.
The Extentia Group was also placed in administration in February.
