One of the most common misunderstandings between homeowners and contractors in Lahore is what a given stage of construction actually includes. A contractor saying "grey structure is done" and a homeowner expecting a livable shell are often picturing two different houses.
Grey structure covers everything structural: foundation, DPC, columns and beams, the RCC slab or roof, and exterior and interior brick walls with a single coat of plaster. At this stage there is no flooring, no electrical wiring beyond conduit piping laid inside the walls, no plumbing fixtures beyond pipe routing, no doors, no windows, and no paint. It is, quite literally, a grey concrete shell — which is exactly why it is called grey structure.
Semi-finished (sometimes called "grey plus") adds a second, smoother coat of plaster, window frames and door frames fixed in place, and the rough-in for electrical and plumbing completed and tested (wires pulled through conduit, pipes pressure-tested) but no fixtures installed yet. Many buyers underestimate how much work sits between grey structure and semi-finished — this is where a large share of the skilled labor cost actually goes.
Finished construction is everything semi-finished has, plus flooring and tiling throughout, paint (primer and at least one topcoat), sanitary fixtures installed and functional, electrical fittings and switches installed and live, doors and windows hung and operable, and kitchen cabinetry if included in scope. "Finished" does not automatically include false ceiling, built-in wardrobes, or landscaping — those are commonly quoted as separate line items, so confirm explicitly whether they are in scope before signing a contract.
Understanding these three tiers matters most when you are agreeing on a payment schedule. A typical milestone-based schedule releases roughly 40% of the budget across the grey structure stage (in sub-milestones — foundation, then roof), 30% across semi-finished, and the remaining 30% across finishing, with a final holdback of 5–10% released only after a punch-list walkthrough. If your contractor is asking for a payment structure that front-loads more than that toward grey structure, it is worth asking why.
