Short answer: there is no responsible one-number answer for every plot. A 3 BHK home moves through feasibility, design, approvals, site work, structure, services, finishing, testing and handover. The best schedule exposes dependencies early and assigns a clear owner to each decision.
A house timeline starts before excavation
The build programme should begin with the plot, not with a masonry date. Confirm the site boundary, soil investigation, proposed built-up area, design brief and approval route first. This avoids expensive redesign after work has begun. If you are still comparing builders, use the same scope and specification sheet for every quotation.
1. Brief, soil review and concept design
Define rooms, parking, future expansion, budget tier and climate response. Site measurements and soil information guide structural design; they should not be guessed from a neighbour's house.
2. Drawings and permissions
Prepare architectural, structural and service drawings, then follow the applicable planning/building-permission process. Keep clarification time in the programme; a submission may need queries resolved before it proceeds.
3. Mobilisation, excavation and foundation
Set out the building accurately, manage excavation safely and construct the foundation system specified by the engineer. This stage should include inspection records before concrete is covered.
4. RCC frame and masonry
Columns, beams, slabs, stairs and walls establish the building shell. Curing periods and quality inspections are programme activities—not spare time to be removed.
5. MEP, plastering and waterproofing
Coordinate electrical conduits, plumbing lines and service openings before finishes close the walls. Test wet areas and terrace waterproofing at the required stage, not after interiors are installed.
6. Finishes, testing and handover
Flooring, joinery, paint, fixtures, final testing, snag correction and cleaning follow in a controlled sequence. Retain time for defects to be fixed before handover.
What commonly changes a Chennai house-build schedule?
- Late scope changes: moving a staircase, adding a floor or switching key finishes after structural or service work is underway.
- Approval uncertainty: incomplete documents, revisions or unanswered queries can hold the planned start.
- Monsoon and site protection: rainwater management, curing and safe material storage need to be planned—not improvised.
- Long-lead selections: windows, stone, custom joinery, fixtures and electrical products need decisions before their installation date.
- Uncoordinated services: plumbing, electrical, AC and false-ceiling decisions can clash when drawings are not coordinated.
How to protect your project programme
Ask for a milestone schedule that names the deliverable, predecessor activity, responsible person and inspection point. Pair it with an itemised BOQ so the budget, material selection and timeline use the same scope. A weekly site review should compare actual progress with the next two to four weeks of work and record any decision required from the owner.
Need a build programme for your plot?
Silux can turn your preliminary brief into a staged scope, BOQ and construction programme for Chennai or Vellore—before the first excavation date is fixed.
Get a project cost estimateBefore you set a handover date
- Freeze the room programme and major finish level.
- Confirm the site information and approval route.
- Approve coordinated architectural, structural and service drawings.
- Set milestone inspections and payment triggers against visible work.
- Order long-lead materials before they become critical.
- Keep a documented variation process for changes.

Frequently asked questions
How long does a 3 BHK house take to construct in Chennai?
It varies by plot, floors, approvals, design and finishes. Build a project-specific milestone programme instead of relying on a generic completion promise.
Can I make design changes during construction?
You can, but assess the time, cost, structural and service impact before authorising each change in writing.
What should a good construction schedule include?
It should show design/approval dependencies, phases, inspection points, decisions due from the owner, material lead times and a handover/snagging allowance.
