How you contract the build decides how much of your budget you control. The difference between the two common models is not just price — it is who carries the work and who carries the risk.
How Do the Two Models Compare?
| Labour-only contract | Turnkey (material + labour) | |
|---|---|---|
| Who buys materials | You | Contractor |
| Pricing | Labour rate per sq ft | All-in rate per sq ft |
| Contractor margin on materials | None | Included |
| Brand control | Full | As written in the contract |
| Your workload | High — ordering, checking, storing | Low |
| Risk of substitution | Low | Higher if spec is vague |
| Wastage risk | Yours | Contractor's (but priced in) |
| Best for | Owners with time, or a trusted site supervisor | Owners who cannot be on site |
Why Is Labour-Only Usually Cheaper?
Material is roughly 55 to 65 percent of a house's cost. A turnkey contractor adds a margin to that material and also prices in the risk of price rises and wastage. Under a labour-only contract you pay suppliers directly, choose when and how much to buy, and keep any saving from buying well.
The saving is real only if you actually buy well and control waste. Cement that hardens in storage, steel cut carelessly and sand washed away in the rain are all now your cost.
What Are the Risks of Turnkey?
Turnkey's convenience is real, and a good contractor delivers exactly what is promised. The risks come from vague contracts:
- "ISI brand cement" or "TMT steel" without a brand, grade or type lets the cheapest acceptable option be used.
- Tile, fitting and door specifications written as "standard" invite substitution.
- Quantities are not your concern on paper, but under-reinforcement or a lean mix is.
A one-page specification — brand, grade and type for cement and steel, named ranges for tiles, fittings, doors and paint — closes most of these gaps.
The Hybrid Most Owners Choose
The common middle path in Hyderabad: buy cement and steel yourself, and contract everything else turnkey or with the contractor procuring it.
Why it works:
- Cement and steel are the two largest material costs — together a large share of the material bill.
- They are easy to specify and check: brand, grade, packing week, weight per rod, certificates.
- They are bought in stage lots, which suits a planned schedule and earns better quantity pricing.
- Everything else — sand, aggregate, bricks or blocks, finishes — stays with the contractor, who manages the daily flow.
What Should Any Contract Include?
- Scope: what is and is not included (sump, septic tank, compound wall, electrical, plumbing).
- Specification: brands, grades and types of every major material.
- Rate and how built-up area is measured.
- Payment schedule tied to completed stages, not dates.
- Timeline, and what happens on delay.
- Who supplies water and electricity during construction.
- Defect liability: who fixes what after handover, and for how long.
The Short Version
Labour-only is cheapest if you can buy and manage materials; turnkey is simplest if you cannot. The hybrid — owner buys cement and steel, contractor does the rest — captures most of the saving with a fraction of the work, and is how many Hyderabad houses are built.
