So when I found this "schoolhouse" as the listing said, I felt a need for a quick Google (sounds rude!) which led me to discover that this building is the old Caralulup PS974. (944 Lexton-Talbot Rd, Burnbank 3371).
Here it is in 1909 (I've borrowed the photo from here). Better days - for the school at least.
Some information on the school is as follows (I've borrowed this from the same site.)
63 students at one stage. If my memory doesn't fail me, that's more than was at my primary school in the 1970s. The "destitute children's clause"...oh dear. I do think 'Caralulup' is a delightful name though.
So it closed in 1928, and appears to have been converted to a residence - when?...and here it is now, yours for $90,000.
Was this the old shelter shed? There's also a derelict tennis court.
I guess I romanticise things, but I do hope someone buys it and gives it some love...imagine how delightful it would be!
