Epping railway station was opened on 17 September 1886, originally named "Field of Mars", and quickly renamed to "Carlingford" on 5 April 1887.

[7][8] The land from the Field of Mars was broken up into farms and orchards, and after World War II it started to convert to residential use.

The extension of the railway line from Sydney to Epping in the 1950s played a key role in connecting the suburb to the city, encouraging more people to settle there.

The area became increasingly attractive to professionals due to its convenient public transport links, proximity to employment centres and schools.

A 2015 review of local government boundaries[broken anchor] recommended that all of Epping be amalgamated into the City of Parramatta, and this became effective on 12 May 2016.

The changes to zoning for this programme cover 54 hectares, including provision for building heights of 8 to 22 storeys (although later proposals are up to 36 stories[12]) for mixed commercial and residential use within a 400-metre radius of the railway station, and about 3,750 additional homes within 800 metres of it.

[13] These zoning changes were finalized and approved in March 2014, although residents have expressed concerns about issues including traffic management, lack of parking, storm water drainage and access to schools.

[14] The first major project under this programme was scheduled to be Grocon's amalgamation of four lots at 30-42 Oxford Street, acquired in September 2015 for a cost of $56 million.
