Dhaka's Airport (now called Hazrat Shahjalal, formerly Zia) was built in the 1980s, at a time when the country was much poorer than now. Considering the limited resources of the time, I think the architecture is reasonably attractive. The airport has received some upgrades and expansions since then, including the addition of a second terminal, but a major overhaul is needed to bring it on par with contemporary international standards. This is now in the works, with a much nicer third terminal likely in the next decade.
