Quick Answer
Grey structure construction is the structural stage of a building: excavation, foundations, the RCC frame, slabs, brick masonry and the pipes and conduits buried inside them. ACCO (Ahmed Construction Company), Lahore, builds grey structures for houses from 5 marla to 2 kanal and for commercial buildings, to approved architectural and structural drawings. Estimates are prepared from a bill of quantities (BOQ), and architectural drawings are free when the construction is awarded to ACCO.

Grey Structure vs Finishing vs Turnkey
| Contract | What you get | Best for |
|---|---|---|
| Grey structure | The structural shell, built and inspected to the drawings | Owners who will manage finishing themselves or later |
| Finishing | Plaster (if not in grey), flooring, paint, doors, windows, fittings, electrical | Owners with a completed shell |
| Turnkey | Design, grey structure and finishing in one contract | Owners who want one team and one budget — see turnkey home builders |
What Decides Grey Structure Cost
ACCO does not quote one per-square-foot rate for every project, because the same covered area can need very different quantities of steel and concrete. The estimate is built from a BOQ based on:
- Covered area and number of floors, including any basement or mumty.
- Structural design — foundation type, column sizes, spans and slab thickness from the structural drawings.
- Soil and site conditions, water table and access for materials.
- Material specification — steel grade, cement, brick class and concrete mix.
- Society bylaws in DHA, Bahria Town, Lake City, LDA and other schemes.
- Contract type — with materials, or labour-only.
For current indicative figures see the house construction cost guide for Lahore, then ask for a project-specific estimate.

Frequently Asked Questions
What is included in grey structure construction?
Typically excavation, foundations, DPC, the RCC frame (columns, beams, slabs, stairs), brick masonry and concealed conduits and pipes. Plaster, waterproofing and basements are agreed case by case. Your ACCO contract lists every included item.
What is the difference between grey structure and turnkey construction?
Grey structure covers only the structural shell. Turnkey construction covers design, grey structure and finishing in one contract, so the house is handed over ready to use.
What details are needed for a grey structure estimate?
Plot size and location, the society, number of floors, any basement, and architectural drawings if available. Structural drawings and a soil report make the estimate more accurate.
Does ACCO offer labour-only grey structure contracts?
Yes. ACCO offers labour-only contracts where the owner buys the materials, as well as contracts where ACCO supplies materials.
Can ACCO continue from grey structure to finishing?
Yes. Many clients start with grey structure and then award finishing to ACCO, or choose a full turnkey contract from the start.
