Planning permission has been sought for a major development in Tallaght described as “a new urban quarter”.

It has been lodged by Dublin based property group Marlet, who want permission to build 438 apartments and 403 bedspace student accommodation units at the junction of Belgard Road and Belgard Square North.

This application, which was submitted before Christmas under the fast track planning process, is the first of a planned two-phase development called “Belgard Gardens”.

As well as the apartments, permission is also being sought to develop a childcare facility, external playing area and 6 retail/commercial units on the 7.2 hectare site Marlet bought in 2016 for a reported €16 million.

Due to the size of the proposed development, which could eventually increase to 1,500 apartments and create new streets, a civic plaza and park, Marlet describe Belgard Gardens as a “new urban quarter” for Tallaght.

Warehouse units for Cuisine de France, Kerry Group and Uniphar previously occupied the site.

Marlet Property Group, founded by developer Patrick Crean in 2014, has grown to become one of the country’s largest property development companies and is backed by a UK finance partner M&G Investments.

In November they paid a reported €56 million to buy the former Apollo House site on Tara Street from NAMA.

A decision on the Belgard Square application is due on  February 22.
