Apartment conversion plans for Belgrave House, Greyfriars in Northampton have been approved.
The proposals will see the unoccupied office block transformed and extended by two floors to provide 122 apartments for affordable housing in an 11 storey building.
70 one bed units and 52 two bed units would be provided.
Northampton Partnership Homes are behind the plans for the building, which dates from the 1970s.
A council document released ahead of the decision on the plans says: “The conversion and extension of the application property to facilitate town centre living is acceptable in principle under the development plan.
“Notwithstanding this, the Council cannot presently demonstrate a five year housing land supply and, therefore, it is necessary to assess the proposal against the presumption in favour of sustainable development.
“In this instance, there would be harm arising from inability of the scheme to mitigate the impact of the development on education, health and open space infrastructure.
“However, it is considered that this harm is outweighed by the benefits arising from the scheme, including the delivery of a significant number of affordable housing units to contribute to an identified need; the increase in central area living to improve the vitality, viability and sustainability of the town centre; the reuse of a vacant brownfield site; the potential for the scheme to act as catalyst for the regeneration of the central area; and the introduction of renewable energy technology, and biodiversity enhancements.”
