A multi-national firm that makes timber doors, windows and stairs has announced plans to close its factory in Suffolk.
Some 194 workers at JELD-WEN's plant at the former Boulton and Paul factory in Lowestoft could lose their jobs.
The firm, which employs 20,000 people worldwide, said its markets in the UK have been hit by the recession and the downturn in the construction industry.
None of JELD-WEN's other UK manufacturing sites in Sheffield, Melton Mowbray or Penrith is affected.
The announcement marks the beginning of a statutory 90-day consultation with the firm's workforce.
A company spokeswoman said: "We are looking for savings in our manufacturing processes in order to remain competitive.
"We know that this is a difficult time for our colleagues in Lowestoft and we will be giving them our full support during the consultation process."
The news comes a week after oil firm SLP went into administration and announced it has made 45 staff in Lowestoft redundant.
