The Future of Living in Dhaka: A 2025 Guide to Integrated Interior Design and Engineering

Building or renovating a property in Dhaka has become more than just an aesthetic choice; in 2025, it is a complex engineering feat. With the full implementation of the BNBC 2020 (Bangladesh National Building Code) and the rise of smart, sustainable living, homeowners and developers are looking for more than just a decorator—they are looking for an authority.

At Sunlit, we provide a “dual-track” approach. We bridge the gap between world-class interior aesthetics and the rigorous technical demands of modern civil engineering, HVAC, and plumbing.

Why Integrated Design Matters in Dhaka’s 2025 Market

Hiring a separate designer, plumber, and AC technician for different purposes are an old and failed practices; expensive as well. Modern Dhaka apartments and commercial spaces require a turn-key solution

1. Seamless Interior Design & Modern Minimalist Trends

Dhaka’s urban landscape is shifting toward Modern Minimalism and Smart Space Optimization. Whether it’s a luxury residence in Gulshan or a compact office in Motijheel, the focus is on maximizing natural light and using sustainable materials like oak wood, marble, and steel.

Sunlit’s Approach: We don’t just “decorate” a room; we engineer it. Our designs prioritize flow and functionality, ensuring that your furniture doesn’t just look good but fits the exact spatial dimensions of your life.

2. Engineering Excellence: HVAC and MEP Services

In a tropical climate like Bangladesh, a beautiful room is useless if it isn’t cool and ventilated. HVAC (Heating, Ventilation, and Air Conditioning) installation is now a core part of the interior design process.

  • Custom HVAC Solutions: We calculate the exact tonnage and ductwork required for your specific floor plan, reducing energy costs.

  • MEP (Mechanical, Electrical, & Plumbing): We ensure that all plumbing and electrical systems are integrated behind the scenes, following the strictest safety protocols.

Navigating the Legal Landscape: RAJUK and BNBC 2020

One of the biggest hurdles for any construction project in Dhaka is compliance. In 2025, RAJUK has digitized the building plan submission process through the ECPS (Electronic Construction Permitting System).

What is BNBC 2020 and Why is it Mandatory?

The Bangladesh National Building Code (BNBC) 2020 replaced the older 2006 version to set higher standards for:

  • Fire Safety: Mandatory egress routes and fire-resistant materials.

  • Structural Stability: Ensuring buildings can withstand seismic activity.

  • Sanitation & Light: Minimum requirements for ventilation and water management.

Sunlit acts as your consultant, navigating the RAJUK plan approval process and ensuring every design modification meets the latest regulatory requirements, saving you from costly revision cycles.
