From what I can gather, the ones remaining close to the train station are for builder allocation only. Theyre 7.5 wide and the house designs are predetermined and parapet both sides.
The other blocks there are a bit bigger and usually advertised as Affinity St or Sunrise estate. The catch is, these are on the opposite side of the freeway. This defeats the purpose imo - if you're going to be in woop woop you may as well be amongst the amenities.
I dont like either of the above. There may be better stuff available in a higher price bracket but I haven't checked. Both because I dont have the money and because I dont think wellard warrants it.
