Dhaka's listed stock amounts to 81 office units spread across 9 buildings, and they concentrate in the northern business belt: Gulshan Avenue, the Mohakhali Commercial Area, Garden Road and the Kawran Bazar block around the UTC Building. Nine addresses is a narrow market, so a tenant in Dhaka is effectively choosing between a handful of towers rather than between neighbourhoods.
Unit sizes in Dhaka run from 5 m² to 530 m² with a median of 77 m². That median points at teams of about ten, while the 530 m² top end is whole-floor territory of the kind head offices in outsourcing, garments and financial services take in Dhaka; between those two poles the 81 units cover most requirements except a genuine multi-floor campus.
Asking rates in Dhaka span $274 to $450 per m² a year, with the market centred at $336. Bottom to top is a factor of less than two, which is tight: inside Dhaka's northern corridor the size you take moves the invoice more than the address you pick.
Budgeting is therefore simple arithmetic in Dhaka — a 77 m² unit runs about $25,900 a year at the $336 median and about $34,650 at the $450 upper rate, a difference of roughly $8,700. Before paying the upper end, check what it covers in practice: lift capacity, backup power and generator hours differ sharply between the 9 buildings and rarely show up in the headline rate.
