Owners of a residential care home in Tattershall have been given the go ahead by East Lindsey District Council to build a 17-bedroom extension.
The extension - at the Bramhall Residential Care Home in Butts Lane - will also feature en suite bathrooms, a staff room, a laundry, a day care room and a day room.
There will also be provision for additional car parking.
The application had attracted concerns from some residents.
However, ELDC’s planning committee gave it the green light after officers recommended the scheme for approval.
Planners have imposed a number of conditions relating to a variety of issues - including the risk of flooding and the protection of existing trees.
In relation to flooding, ELDC said that before work starts, full details of the means for surface water disposal will have to be submitted to and approved by planners.
The council also stresses that none of the existing trees on the site - apart from those shown for removal on the application - can be cut down or lopped, without prior consent.
Another condition relates to a travel plan which planners stress must be in operation when the extension is in use.
Residents had previously written to the council expressing concern about parking arrangements.
One resident claimed the addition of up to six more spaces was “totally inadequate” considering the extra staff, residents and visitors.
They also claimed emergency vehicles had encountered problems entering the premises - and that extension would lead to the loss of garden space.
Tattershall Parish Council did not object to the scheme but Highways officers did initially express concerns.
