The former Southern Cross Post Office building dates back to the 1890's and was designed by the eminent Government architect George Temple Poole Ideally located on an 1148 square metre corner block on the main street of Southern Cross there is ample nearby parking. The age of the buildings gives them plenty of charm, with tall ceilings and many of the original features intact. The Post Office section of the building consists of a retail showroom area, large counter, lunchroom and two separate toilets. The adjoining residence consists of three bedrooms, study, formal lounge room, kitchen and laundry. The property is currently vacant, however lends itself to dual occupancy, which could enable investors to lease the dwelling and commercial premises separately for a greater rate of return The significance of the Southern Cross Post Office has been recognised by the Heritage Council of WA, and the building was entered on the Register of Heritage Places on a Permanent basis in February 1996.
