It's a 235-acre landbank, according to The Irish Times.
According to today's Irish Times, two developers based in the county have paid more than €5 million for the “Castletown Lands”, a 95-hectare (235-acre) landbank in Celbridge.
The developers are Straffan-based Killross Properties and Springwood, and both have a long history of developing residential and commercial schemes in North Kildare.
According to Ronald Quinlan's article, the sale of the lands was brokered by agent Cushman & Wakefield on behalf of Janus Securities Ltd.
Situated immediately adjacent to the landmark Castletown House and its demesne, which is owned by the State and open to the public under the auspices of the OPW, the “Castletown lands” are predominantly zoned Objective F – Open Space and Amenity under the Celbridge Local Area Plan 2017-2023.
The remaining portion of the site is zoned GB – Green Belt.
The lands are designated within a Historical Landscape Area and have mostly been in agricultural use for several years.
