Unity Complex – Building Design Competition by IAB, Purbachal
Competition concept for United Group: site planning & architecture
In 2012, Studio Archifiction prepared the Unity Complex proposal for the IAB competition in Purbachal for United Group.
The scheme organizes five similar residential blocks around shared community space and generous open areas. Circulation is clear. Ground levels stay active and connected.
Each unit is individually planned for daily comfort. Kitchens, living, and bedrooms align for privacy and ease of use.
The building design follows climate-friendly principles: block orientation, shaded edges, and cross-ventilation through courtyards. Daylight is balanced to reduce heat gain while keeping interiors bright.
Open terraces extend living outdoors and create social pockets between blocks. Simple structural grids and compact cores make construction efficient and scalable.
Overall, the concept blends site planning and architecture to deliver a humane residential environment—where community space, airflow, and light shape the experience. This competition entry demonstrates our approach to building design that is practical, livable, and context-aware.
Competition entries like Unity Complex are not shelf pieces for us. The block planning and cross-ventilation ideas tested here later shaped real commissions such as Dr. Jasim’s G+6 residential building in Bashundhara, which we carried from first sketch through RAJUK approval to handover. Competition entries like this are where an architecture firm in Bangladesh shows its planning values in public: block orientation, shared open space and climate response, judged by peers at IAB.

Competition work is where we test ideas before clients pay for them.
The site planning and block arrangement worked out here went on to shape real commissions. If you are holding a site and want to know what it can carry, that conversation costs nothing to start.
