These pictures show how much has changed since the original office complex was demolished.
The land where Ashdown House once stood has now been redeveloped to create a new housing estate of 151 new homes and an Aldi supermarket.
Demolition of Ashdown House, which was formerly used by the Department of Work & Pensions (DWP) and other businesses, started in January 2023 and completed in June.
Plans for the scheme on the land between Sedlescombe Road North and Harrow Lane were given the go-ahead by Hastings Borough Council in January 2022.
Work suffered a minor setback in May 2024 when an explosive shell was discovered. Surrounding buildings were evacuated as The Ministry of Defence sent its explosive ordnance disposal team to detonate the 105mm (4.13in) shell.
The opening date for a new East Sussex Aldi store has now also been revealed as Thursday, February 12, at 8am.
