Liam O'Connor's Classical designs for a new Armed Forces Memorial are starting on site today.
A turf-cutting ceremony will be held in the National Memorial Arboretum, near Lichfield, Staffordshire, where the memorial will be situated.
O'Connor won a national competition last year, seeing off Modernist proposals by the likes of Chris Dyson.
The Ministry of Defence (MoD) said O'Connor's Portland Stone designs were key to the success of the project.
'The Armed Forces Memorial is a unique and exciting development that will recognise all UK servicemen and women who have been killed on duty or as a result of terrorist action since the end of World War Two,' an MoD spokesman said.
'It will have the name of each serviceman and woman engraved on it,' he added.
