Four blocks of flats in Llanelli are to be demolished - potentially in March - as part of a longer-term revamp of the area.
Carmarthenshire Council has submitted a prior demolition notice outlining its plans for Ty Cydwel, Ty Meriel, Ty Elizabeth and Ty Howard, in the town's Tyisha ward.
The complex in Maes Y Gors has 44 flats, but it is understood that only two of them are still occupied for now.
One of the blocks is also home to Tyisha Food Bank, which will be relocated.
The blocks were built in the 1960s and do not fit in with the council's long-term plans for the area.
Multi-million pound regeneration proposals for Tyisha include 110 new housing units - some owner-occupied - new shops and offices, improvements to the nearby Llanelli railway station, and more attractive links to the town centre and the life science and wellness village which will be built at Delta Lakes to the west.
The old goods yard could also be turned into offices and potential community facilities.
The council has updated its website about the £9 million regeneration scheme, which was approved last year.
"The aim is to transform the area into a place where people want to live and work," it said.
A community steering group has been set up and the council is working with Dyfed-Powys Police and Llanelli Town Council, among others, to drive forward the project.

It said Tyisha was the most densely-populated ward in the whole of Carmarthenshire, with many rental properties which were in low demand and difficult to let.
The council also wants to improve the surroundings of young people's accommodation at Clos Sant Paul and the environment at Ger Y Lan.
Tyisha is one of the areas in Llanelli which is part of a new public space protection order to help combat alcohol-related crime and anti-social behaviour.
The council said it was addressing fly-tipping issues, and would soon be recruiting community wardens to patrol Tyisha.
The Reverend Captain Robert Lowe, whose parish used to include St Peter's Church, which is behind the flats earmarked for demolition, said he commended plans to revitalise the area.
"Definitely any improvement is good," he said.
Reverend Lowe, who now runs the Impact 242 Llanelli Centre of Mission in New Dock, Llanelli, said he believed two-bedroom houses and bungalows would be good options in terms of housing.
He felt there was still a strong demand for rental accommodation.
"They (the council) must have something in mind," he said.
