Sheraton's new look
Sensible societies have educated bodies who decide if important buildings or buildings (or modifications to them) in important locations are suitable from the aesthetic and environmental point of view even after the design has been granted planning permission. For example, the UK has the Royal Fine Arts Commission, New Delhi has the Urban Arts Commission. These are to protect the visual and environmental quality of the city. Such bodies are composed of architects, engineers, artists, poets etc. Dhaka should have had one long time ago and there is still time.
