Bluemantle, who are in charge of the £200 million Horwich Loco Works regeneration, have published a full masterplan.
The document includes an update for the 1,700-home Rivington Chase scheme off Chorley New Road.
The masterplan details the layout of the homes and open space and shows the proposed highways network including the spine road linking Horwich to Middlebrook.
Bellway Homes submitted its application to build the first 112 homes on the site earlier this year.
Residents and councillors were shown the masterplan at a recent meeting of the Rivington Chase Liaison Committee.
