Timelines slip in predictable ways. A realistic schedule, built stage by stage, shows where the time really goes and which delays you can prevent.
Typical Timelines
| House | Design and approval | Construction | Total |
|---|---|---|---|
| Single floor (~1,000–1,500 sq ft) | 1 – 3 months | 6 – 9 months | 7 – 12 months |
| G+1 (~2,000–2,500 sq ft) | 1 – 3 months | 9 – 14 months | 10 – 17 months |
| G+2 (~3,000–3,600 sq ft) | 1 – 3 months | 12 – 18 months | 13 – 21 months |
Stage Durations for a G+1
| Stage | Duration |
|---|---|
| Excavation and foundation | 3 – 6 weeks |
| Plinth, filling, anti-termite, DPC | 2 – 3 weeks |
| Ground floor columns, beams, slab | 4 – 6 weeks |
| First floor columns, beams, roof slab | 4 – 6 weeks |
| Masonry, both floors | 5 – 8 weeks (overlaps) |
| Electrical and plumbing rough-in | 2 – 4 weeks (overlaps) |
| Plastering | 5 – 8 weeks |
| Waterproofing | 1 – 2 weeks |
| Flooring and tiling | 4 – 6 weeks |
| Doors, windows, painting | 5 – 8 weeks |
| Fittings, cleaning, handover | 2 – 3 weeks |
Overlap — finishing the ground floor while the first floor's structure goes up — is what keeps a G+1 near the lower end of the range.
Why Each Slab Takes Weeks
A floor's frame involves column casting, formwork for beams and slab, steel fixing, conduits, the pour itself, curing, and the minimum time before props come out — 7 days for typical slab spans and 14 days for beams under IS 456 with OPC, longer with PPC. Those waiting times should not be shortened.
What Causes Delays?
| Delay | Prevention |
|---|---|
| Design changes during work | Finalise drawings and specification first |
| Materials not on site | Order each stage's materials a few days ahead |
| Labour shortages (festivals, harvest season) | Plan around them; keep a buffer |
| Payment delays | Stage-linked payment schedule, funds ready |
| Approvals | Apply early; build only what is approved |
| Monsoon | Get below ground and under a roof before June |
| Decisions on finishes | Choose tiles, fittings and colours early |
Fitting the Hyderabad Seasons
| Start month | Effect |
|---|---|
| October – February | Foundation and frame in dry weather; internal work in monsoon |
| March – May | Fast progress but hot; careful curing; foundation done before rains |
| June – September | Monsoon interruptions to excavation and slabs |
The Short Version
Plan 9–14 months for a G+1 after approvals. Lock the design, have materials on site before each stage, and start between October and February if you can. The concrete's waiting times are not the delay — late decisions and late deliveries are.
