The proposed development of a new housing complex at Saint Brigid's Cottage in Celbridge has been denied approval by the local council.
The plans involved the demolition of an existing house and shed to clear the site for redevelopment.
The proposal outlined the construction of four blocks, each comprising three storeys above ground with a partial basement below ground level.
It would have included thirty eight one bedroom units designed for older persons, with terraces at ground level.
Amenities were also planned to include a communal area with provisions for education classes and a coffee dock.
