A plan to convert a 1960s concrete block into modern housing has hit another delay after workers found a problem with the lift shaft.
Neville House in George Street has been undergoing a £1.5m refurbishment during the past year.
It had originally been due to open late last summer but its opening was delayed by twelve weeks because of issues putting up scaffolding.
Cladding then had to be removed to measure all the windows.
Tenants had then been due to move in during February, but now the council has admitted that issues with the lift shaft have again delayed the handover.
A Corby Council spokeswoman said that building work had now finished and that the lift should now be commissioned by the end of next week.
It is believed that the flats have all been allocated and tenants are waiting to move in.
The building had lain empty for ten years before being bought from PA Housing by Corby Council to provide 12 maisonettes for social housing tenants.
The project was funded by right-to-buy receipts and is set to bring the number of social housing completions by Corby Council to 242 since 2010. The work has been carried out by CAFOS limited.
