What is going on?

When I went to live in Road 33, Gulshan 2, in 2007, I was very impressed by the development of the lakeside pathway which extended right up to the bridge at Kamal Attaturk Avenue. It was an enchanting walk. All human life was there a real glimpse of what I believe is the real Bangladesh - rich and poor, young and old, enjoying the beauty of the scenery. I took lots of photos.
Mind you, one naughty builder had put all his building materials at the back of his house, over the footpath, so the paving had not been able to be laid there and one had to scramble over the stuff but I just shrugged and muttered about those determined to spoil honourable attempts to beautify Dhaka.
The building of the new bridge began and the path was blocked off at that point but it still made a nice late afternoon walk up to the point where one could peer over the barrier to see the progress being made. I rejoiced that the caretaker government seemed to be having a real impact and dared to have great hopes for the future.
Last July, I moved house (or, as one says in these parts, 'shifted') but revisited my previous flat recently to collect some mail - and was absolutely horrified to see the access to the lake-side path blocked by a wire fence and someone had built a house over the footpath on the other side of it!
What is going on? Has all this been done with permission? If so, whose?
