A duplex house is a two-story single-family home, and one of the most sought-after residential formats in Bangladesh often extended to three stories as a triplex or villa-style home. Level Seven Architecture & Construction designs and builds duplex and triplex homes across Dhaka and beyond, handling everything from the initial layout through structural design and, if needed, full construction.
Well-planned duplex homes in Bangladesh are typically organized into distinct functional zones:
Entry and guest zone — a formal entrance and living area kept on the ground floor, close to the main entry, to preserve privacy for the family living areas above
Service zone — kitchen, dining, and utility spaces, generally also on the ground floor
Family living zone — bedrooms, a family living area, and private spaces typically placed on the first floor, away from guest and service traffic
Terrace and rooftop spaces — increasingly common additions, ranging from a simple family terrace to a rooftop garden or gym
We design the internal staircase connecting the floors as both a functional element and an architectural feature, and can incorporate landscaping, water features, or a rooftop pool where the plot size and budget allow.
Duplex construction costs in Bangladesh vary significantly by location, floor area, and finish quality. A modest home might run in the range of tens of lakhs of taka, while a larger, higher-finish home can run into crores. We provide a detailed, itemised cost estimate covering design fees, site preparation, foundation, superstructure, finishing, electrical, and plumbing before any construction begins, so the budget is clear from the start.
