Designing for soft soil, salt and humidity

Much of Khulna sits on soft, low ground near tidal rivers. Salty water and damp air affect foundations, steel and finishes.

Construction Site Team
Soil test and piles
Soft clay often needs pile foundations. The soil test decides the type and depth.
Protect the steel
Good concrete cover, proper curing and clean sand protect rebar from salty moisture.
Damp proofing
A damp proof course above plinth level and a raised plinth keep ground moisture out.
Humidity safe interiors
Marine ply or PVC board near water and coated hardware that does not rust.

Architect in Khulna: common questions

Who approves building plans in Khulna?

Inside the Khulna development area, the Khulna Development Authority (KDA) approves building plans. Outside it, the pourashava or union parishad gives permission.

Often, yes, for buildings of several storeys, because much of the city sits on soft soil. A soil test with boreholes tells your engineer what you need.

Residential construction costs about ৳1,800 to ৳2,500 per sq ft in 2026 for the structure and standard finishing. Soft soil, a raised plinth or pile foundations can add to this.

About ৳900 to ৳1,500 per sq ft for a budget finish, ৳1,500 to ৳2,500 for mid range and ৳2,500 to ৳4,000 or more for premium work in 2026, including design, materials and labour.
