FAQs
How much does it cost to build a 10 Marla house in Lahore or Islamabad?
Use our Construction Cost Calculator to compare grey structure and finishing costs per square foot. Get a ballpark instantly, then message us on WhatsApp for a site‑specific, itemized proposal with timeline and payment schedule.
What is the current grey structure rate per square foot in DHA Lahore and Bahria Town?
Rates vary by design, specification, and market conditions. Our calculator uses local benchmarks for concrete, steel, and masonry. Share drawings for an updated quotation with inclusions, exclusions, and a fixed‑price or labor‑only option.
How do I calculate FAR/FSI and buildable area under LDA/CDA/DHA bylaws?
Enter plot size, setbacks, and height in the FAR Calculator to test compliance. We’ll validate assumptions and propose a concept plan maximizing covered area, parking efficiency, and natural light—ready for authority submissions.
What’s the typical timeline to construct a 1 Kanal house in Islamabad?
Most 1 Kanal homes complete in 10–14 months depending on design complexity, approvals, and finishes. Use our calculators to plan budgets and milestones; then request a detailed Gantt schedule with procurement and quality checkpoints.
Should I choose turnkey construction or labor‑only contracts?
Turnkey simplifies coordination and cost certainty; labor‑only can appear cheaper but shifts risk to you. We’ll compare both models using your calculator results and issue a transparent BOQ, payment plan, and workmanship warranties.
How do I estimate tile, paint, and lighting quantities accurately?
Our Interior & Finishing Estimators calculate coverage, wastage, and recommended lumen levels by room type. Export quantities and specifications, then ask us for brand‑specific selections that balance performance, durability, and warranty.
Which is better in Pakistan—aluminum or uPVC windows for energy efficiency?
Both can perform well if specified correctly. Use the Windows & Glass Estimator to compare U‑values, glazing thickness, and cost. We’ll propose the right profile, hardware, and seals for Lahore/Islamabad climate and budget.
