LIVE DESIGN-STAGE CALCULATOR

Now go deeper — every material, finishes first.

This is the full materials calculator. It turns a detailed material takeoff into an embodied-carbon report in real time. Finishing materials are listed first in the index below, followed by structure, envelope and every other category. Type quantities and watch total carbon, water, energy and hotspots update as you build.

Calculate Grey Structure

Enter your covered area in square feet or Marla and get a generic estimate of grey-structure materials — cement, steel, sand, crush and bricks — plus the associated embodied carbon. Grey structure only: foundation, RCC frame and structural brickwork up to plaster-ready stage. Finishing items are excluded.

1 Marla ≈ 225 sq. ft. is used throughout this tool. Regional definitions vary slightly. Commercial rates assume a multi-storey RCC frame.
Material index

Grey structure materials — per sq ft rates

Generic quantity rates per sq ft of covered area for a typical RCC-frame grey structure in Pakistan. Residential and commercial rates differ because high-rise commercial structures carry heavier loads and more reinforcement per sq ft.
