A compound is a big parcel of lot - more than 1,000 square meters but less than 1 hectare. Those who have money had invested in such before the start of this millennium. The rationale is to gain value of the land and at the same time earn from it. However, the investment is quite huge so only the rich ones can afford. Normally, compounds have small houses inside for renting out. That's where they get the income to further develop the compound. Some compounds have swimming pool and small clubhouse like structure.
