This particular building looks like it is using the similar design from Cameron Highland (West Malaysia).
One of the newer buildings…
Aaahh… I remember these petrol stations very well. We used to top-up our petrol here when we drove from Miri/Bintulu/Sibu before the last sector to Kuching.
Opposite these petrol stations, once upon a time, were a few rows of wooden shophouses. They got burnt down some years back and now replaced by concrete shophouses (picture below). If I’m not mistaken there’s still one more row of wooden shophouse left.
The main road through Serian town.
