Last year, I posted this photo of a house along Nguyễn Văn Trỗi Street in the Phú Nhuận District.
The front half or two-thirds of the house had been sliced off to accommodate the widening of the street. As streets are widened, the government takes back land use rights and compensates the rights-holders, who can then sell the remaining property or fix up what is left.
Not well done architecturally, in my opinion. But it would up being a highly-visible location for a large advertising sign.
