Complete Guide to Building a Duplex House in Pakistan (2025 Costs & Designs)

Pakistan’s real estate market is thriving with a projected growth rate of over 5% annually through 2028. With a housing deficit exceeding 10 million units, duplex houses are becoming a popular choice for maximizing space on limited plots in cities like Lahore, Islamabad, and Karachi. At Afaq Ahmad Constructions, we’ve built numerous duplex homes, offering efficient designs for families or investors. This complete guide covers costs, designs, and a step-by-step process for building a duplex house in Pakistan in 2025, helping you navigate the market with confidence.

What is a Duplex House?

A duplex house is a multi-family dwelling divided into two separate units, often sharing a common wall but with independent entrances, kitchens, and bathrooms. In Pakistan, duplexes are ideal for extended families or rental income, fitting on 5-10 Marla plots (1,125-2,250 sq ft). They can be side-by-side or stacked (upper and lower floors), offering privacy while optimizing space. In 2025, duplexes align with the Naya Pakistan Housing Program’s focus on affordable, multi-unit homes, reducing the housing gap while providing economic benefits.

Why Build a Duplex House in 2025?

Pakistan’s urban expansion, with Lahore’s population over 14 million, demands efficient housing. Duplexes provide two units on one plot, saving land costs (PKR 50-70 lakh for 5 Marla in Johar Town) and generating rental income (PKR 30,000-50,000/month per unit). The Green Building Code 2023 encourages sustainable duplex designs, while material costs (e.g., cement at PKR 1,060/bag) and labor rates (PKR 450-500/day) have risen by 5-7%, per our cost blog. Duplexes can save PKR 500,000-1 million compared to two separate homes, with a 24-40 week timeline, per our timeline blog. They also boost resale value by 10-15% (PKR 1.6-3 million for a 10 Marla duplex).
