Keith Astley, a councillor who spoke for the town council, acknowledged the need for care provision, but also said the plans would end the possibility of extending a neighbouring cemetery.
According to the Local Democracy Reporting Service, concerns about the development were also raised by the Daventry Allotment and Garden Association.
The association said building the homes would involve the demolition of a local shop, external used by the community.
However, the agent for the application told the committee its client was “committed to replacing the shop building”, but it would not be on the land he owned.
A previous proposal for the site, which included an 85-bed care home, 24 extra care apartments and 16 independent-living maisonette units, was approved in 2019, but the agent said that the planning permission lapsed due to complications around Covid.
