Builder St Marys, Penrith
St Marys is the LGA's secondary CBD with its own station and shopping precinct — Queen Street the spine, R3/R4 redevelopment ramping around the station with the upcoming Western Sydney Airport rail link. Older fibro/brick stock on side streets ripe for KDR. Industrial-legacy contamination overlays on the eastern edge.
