Rationale: Why is this case interesting?
The commercial building "BGMEA" has been standing illegally in the middle of Hatirjheel lake, obstructing the water flow, as well as creating visual and aesthetic disturbance.I would like to attempt for a design solution to make the site more interactive with public and nature, without completely demolishing the building,to ensure the continuum of the urban-public characteristics of the rest of the lake.

Green Infrastructure benefits for this site
Environmental Benefits
Preservation of local habitat
Green Infrastructure can attempt to restore the original ecological cycle at the site by regenerating living processes and integrating it with man-made structures.
Retaining storm-water
It can reduce storm-water runoff volumes by utilizing the natural retention and absorption capabilities of vegetation and soils.
Enhanced Groundwater Recharge
The natural infiltration capabilities of green infrastructure technologies can improve the rate at which groundwater aquifers are recharged. Enhanced groundwater recharge can also boost the supply of drinking water.
Improved Water Quality
Green Infrastructure techniques infiltrate runoff close to its source and help prevent pollutants from being transported to nearby surface waters.
Improved Air Quality
Green infrastructure facilitates the incorporation of trees and vegetation in urban landscape, which can contribute to improved air quality.
Increased Carbon Sequestration
The plants and soils that are part of the green infrastructure will serve as sources of sequesting carbon.
Urban Heat Island Mitigation and Reduced Energy Demands
By providing increased amounts of urban green space and vegetation, green infrastructure can help mitigate the effects of urban heat islands and reduce energy demands.
Social Benefits
Creating Recreational Space
Green Infrastructure can improve the life and living of the inhabitants by providing recreational spaces in the form of greenways, parks, urban forests, wetlands etc. This is more true for this site as it was being treated as a dumping back-yard; and also because there is an acute shortage of land in this densely populated city of Dhaka.
Improved sense of community
By increasing access to places for gathering and interacting, Green Infrastructure can boost the sense of belongingness, sense of community among the people. This can be improved to a better extent if the people can participate in the management and maintenance.
Improved Aesthetic Quality
Green Infrastructure can greatly improve the aesthetic quality of the site.
Improved Public Health
With improved environmental and aesthetic quality, reduced pollution, places for exercising activities; Green Infrastructure can imrove the physical, mental and spiritual health of the people.
Economic Benefits
Cost Effective
Green Infrastructure is cost effective as it requires less capital investment and maintenance cost. It can also lessen the associated wastewater pumping and treatment cost.
Reduced Transport cost
Waterways can be an economically efficient and energy-saving mode of transport.
Income Generating Potentials
Income can be generated from various recreation facilities; like boating, fishing etc. Yields from local agriculture can generate income too.
Other economic benefits
Reduced energy consumption and health care cost can be considered as economic benefits.
Potential for multifunctionality
Green infrastructure has typically multiple functions. What could be achieved for your site in this respect?
