Sound Proof Walls Open Freeway Development Opportunities
Hayball director and architect Tom Jordan said acoustic engineering is such that residents in an apartment building whose back wall is a thick “sound wall”, would hear traffic noise from the much quieter Fitzgerald Road nearby, moreso than the freeway offramp which it abuts.
Developer of the estate Millenium Properties, a joint venture between the Salta Group and Psaltis Ryobi Group, had to build a “sound wall” longer than 1 kilometre, to win council approval for the $40 million Glen Gala housing estate.
Glen Gala is near the former Sunshine Golf Course, which has been developed into a housing estate for Australand.
Mr Jordan said building townhouses into the 2-metre wide “sound wall” served to provide medium density housing in the Sunshine West area, as well as look more attractive to residents, than a tall imposing wall.
