The flat where a woman was fatally poisoned with the nerve agent Novichok is being demolished.
Dawn Sturgess, 44, collapsed at her partner Charlie Rowley's home on June 30, 2018 after spraying herself with a perfume bottle containing Novichok.
The mum-of-three died in Salisbury District Hospital, Wiltshire, seven days after collapsing on June 30.
Mr Rowley, now 47, was left seriously ill but recovered.
His flat in Amesbury is situated eight miles away from Salisbury, where Russian former agent Sergei Skripal and his daughter Yulia were poisoned with the nerve agent in March 2018.
They also recovered, having initially been found unconscious on a bench in the southeastern city.
At first police had believed Ms Sturgess and Mr Rowley had taken contaminated drugs.
Mr Rowley later revealed that he had found a bottle of perfume and given it to his partner as a gift.
She had sprayed it on her skin, with neither of them aware that it contained the deadly agent.
On Monday, housing provider Stonewater said it had worked "very closely" with Wiltshire Council and consulted with residents on the best way forward for Mr Rowley's former home.
It confirmed that demolition work was now under way at two flats on Muggleton Road.
"The cleared area will be landscaped, creating additional green space for the local community and we'll be providing two additional homes at an alternative development nearby to ensure that there is no loss of affordable housing in south Wiltshire," a spokeswoman said.
"Whilst we cannot forget the events that unfolded at this property, we're pleased that we've been able to work together to come to this successful conclusion and we'll be doing our absolute best to minimise disruption."
