Louis Kahn designed the entire Jatiyo Sangsad complex, which includes lawns, lake and residences for the Members of the Parliament (MPs).

Location and basic layout
The main building is divided into three parts:
1.    The Main Plaza: 823,000 square feet (76,000 m²)
2.    South Plaza: 223,000 square feet (21,000 m²)
3.    Presidential Plaza: 65,000 square feet (6,000 m²)
The main building is at the center of the complex. The outer parts of the complex include the MP hostel. An intricately designed lake surrounds the main building.

Design philosophy
Kahn’s key design philosophy optimizes the use of space while representing Bangladeshi heritage and culture. External lines are deeply recessed by porticoes with huge openings of regular geometric shapes on their exterior, shaping the building’s overall visual impact.

In the architect Louis Kahn’s own words:
“In the assembly I have introduced a light-giving element to the interior of the plan. If you see a series of columns you can say that the choice of columns is a choice in light. The columns as solids frame the spaces of light. Now think of it just in reverse and think that the columns are hollow and much bigger and that their walls can themselves give light, then the voids are rooms, and the column is the maker of light and can take on complex shapes and be the supporter of spaces and give light to spaces.

I am working to develop the element to such an extent that it becomes a poetic entity which has its own beauty outside of its place in the composition. In this way it becomes analogous to the solid column I mentioned above as a giver of light.
It was not belief, not design, not pattern, but the essence from which an institution could emerge…”
