The Chawk complex area is adjacent of the Chawk market and other congested areas like bakshi bazar, Begumganj. While the surrounding area offers no open space for recreation, this zone is built to meet that need. The site was previously used by the prison office has a ancillary space where they built tin shed structures for storage and personnel residence. It is bound to the northern side by the jail Boundary wall that dates back to Mughal times. The retention wall of the pond also dates back to Premughal era. A mosque was also present on site that has been redesigned and replace the existing mosque.

The proposed Chawk complex area consists of mostly open spaces.

It has Chawk market building that houses traditional food market and book shops. On either side of the market are futsal field and badminton court areas that will be open to the public. For the elderlies of the community senior citizen park has been designed equipped with gym equipment.

The Children's play area is another out door space it offer free area as well play equipment for children of different ages. It also includes a running and cycling track all of which has been built to a certain standard so that it is safe for the regular users of all age. The pond has been present in the site from pre Mughal times, remains of the Premughal retaining wall has been found on site and are on display at the park ghat. The pond is surrounded by an experiential walkway. The walkway has two ghats, the remain of one of them has been found, conserved and recreated, the other ghat has been built in reminiscence of the old ghat that might have been present adjacent to the mosque. A mosque had been present on site before the existing mosque had been relocated until the new mosque had become operational.

Old Dhaka central jail is edged by Chawk market, which is a popular wholesale destination for many businesses for the country. More over the traditional food market has existed for a long time in the history of the place. The morphology of the place is such that it has grown to become a crowded, tightly packed market place, offering no ventilation or open space. The design of the new Chawk Market is a two storied construction consisting of traditional food market in the ground floor and book market in the upper level. The market is a stark contrast to the existing chawk market, as it is open and airy allowing -air, rain, light- all the elements to enter the space freely. Every thing from the height to the finish have been deliberate decisions based on survey and observations on site. The structure was built with the intension of building a flowing open space with just a super roof for shade. The cardinal direction are open and serve and service fuctions have been placed in such a way as to reduce solar heat gain and creating a comfortable space that does not require air conditioning. The height on the building had been governed by the height of the adjacent Mughal boundary walls. The roof also acts as vantage point to view the surrounding Dhaka city as well the rest of the jail site.

The access of light through deliberately placed light wells and filtered light through the jail work makes for a spiritual space for prayer. The space is designed to feel monolithic and grand further enhancing the spiritual ambience of the space. The materials used along with the monolithic RCC

The materials used along with the pigmented RCC are all complimentary. The terrazzo floor to the Ms edging all make the structure more durable while the tones all go with each other.

The cast iron jalis are custom-designed, drawing from traditional Islamic motifs found in the Kara Central Jail mosque. Serving as both functional and aesthetic elements, the screens define the boundary between the prayer space and its surroundings while permitting natural light and ventilation. Fabricated from recycled metal, the jalis are engineered for durability, ensuring longevity within the high-traffic public environment.

The craft of this recycled metal has been a traditional practice of old Dhaka for centuries and that craft has not only been implemented rather celebrated here.

MS metals have been used to give an old textured outlook due to the Cortan finish. The choice for this finish comes from a process of trial and error showing it to be durable, while blending into the rustic historic ambience of the site.

Chawk complex area had previously been used by the jail authorities for their use. The area was filled with temporary structures. There used to be a mosque on site, which had been relocated until the new design was built in its place. This zone is partially done with construction with the mosque being completed and functional, the Chawk complex building also set to be open to public. The children’s play area has also been done. Other facilities such as elderlies gym area , a walking track and a futsal field are also present in this area.

While there maybe many play fields in the area , this part of zone B has accommodation for a variety of activity including, separate play area for toddlers and older children, Bi cycle stand, running track, a walking track along the pond, a futsal court, tennis courts and gym equipment for older citizens.
