Stages of House Construction in Bengaluru: A 12-Step Guide
Every stage of house construction in Bengaluru, from soil test to handover, with typical planning ranges, what is checked at each step and what delays it.
A house in Bengaluru is built in about 12 stages: approvals and soil test, site marking, excavation and foundation, plinth, columns and slabs for each floor, masonry, plastering, services, waterproofing, flooring, finishing and handover. For a G+1 house of around 2,000 sq ft, the build itself is often planned at 9 to 12 months after approvals. That is a typical planning range, varies by site, weather and approvals, and it is not a promise.
Stage by stage, with typical planning ranges
Every duration below is a typical planning range, varies by site, weather and approvals. The ranges assume a G+1 house on a regular plot with steady labour and no long monsoon stoppage, come from general site experience rather than a standard or an authority, and are not promises or Buildryt contract dates. For the month-by-month view, see how long a house takes to build. Concrete needs time to cure, and no honest schedule skips that.
| # | Stage | Typical planning range (varies by site, weather and approvals) |
|---|---|---|
| 1 | Design, soil test, plan sanction | 1 to 3 months (depends on the authority) |
| 2 | Site marking, excavation | 1 to 2 weeks |
| 3 | Foundation (footings, pedestals) | 3 to 5 weeks |
| 4 | Plinth beam, filling, plinth slab | 2 to 4 weeks |
| 5 | Ground-floor columns and roof slab | 5 to 7 weeks |
| 6 | First-floor columns and roof slab | 5 to 7 weeks |
| 7 | Brickwork or block masonry | 4 to 6 weeks (can overlap) |
| 8 | Electrical and plumbing conduits | 3 to 4 weeks (overlaps) |
| 9 | Plastering, waterproofing | 5 to 7 weeks |
| 10 | Flooring, tiling, doors, windows | 6 to 8 weeks |
| 11 | Painting, fixtures, final fittings | 4 to 6 weeks |
| 12 | Cleaning, snag list, handover | 1 to 2 weeks |
Several stages overlap, which is why the total is less than the sum of the rows. Total on-site time as a typical planning range: roughly 9 to 12 months, varying by site, weather and approvals.
What happens in each stage, in plain words
1. Design, soil test and sanction
A soil investigation tells the structural engineer how much load the ground can carry. This decides the foundation type. Then the architectural and structural drawings are made, and the plan goes to the local authority for approval. Sanction timelines depend on the authority and the plot, so treat any fixed promise with caution. Our plan sanction guide explains the steps. Rules change; confirm with your architect or the authority.
2. Marking and excavation
The building outline is marked on the ground from the approved plan. Check the setbacks on the ground yourself, with the drawing in hand, before digging starts. It is the cheapest time to fix an error.
3. Foundation
Steel is tied, shuttering is fixed and concrete is poured for the footings and pedestals. Before the pour, the engineer checks bar diameter, spacing and cover. This is the time to ask for cube test reports to begin.
4. Plinth
The plinth beam ties the foundation together and sets the floor level. Plinth height above road level matters for drainage. Ask your engineer to explain the choice in your drawing.
5 and 6. Columns and slabs, floor by floor
Columns go up first, then beams and the slab are cast together. Curing is not optional. IS 456:2000 (clause 13.5.1) asks for moist curing of at least 7 days for ordinary Portland cement concrete, and at least 10 days where mineral admixtures or blended cements are used or the weather is hot and dry. Formwork is removed based on strength and the engineer's instruction, not just the calendar.
7. Masonry
Walls are built with red bricks or solid concrete blocks. The standards that matter are IS 1077 for burnt clay bricks and IS 2185 (Part 1) for concrete blocks. Plumb, line and mortar mix are checked on site. Our guide to blocks versus bricks helps you choose.
8. Electrical and plumbing rough-in
Conduits and pipes are fixed inside the walls before plastering. Plumbing lines should be pressure-tested before they are covered, because a leak behind finished tiles is expensive to chase.
9. Plastering and waterproofing
Plaster is applied in coats. Terraces, bathrooms and balconies are waterproofed and then flood-tested, meaning they are filled with water and watched for leaks before tiles go on.
10 and 11. Flooring, doors, windows, paint and fittings
This is the stage where the house starts to look like a home, and where most changes get requested. Every change is a cost and a delay, so freeze your choices early.
12. Handover
Walk the house with a snag list: tile hollow spots, door alignment, tap pressure, switch points, paint finish. Collect drawings, warranties and documents. For power and water connections, the BESCOM and BWSSB deposits are normally paid by the owner directly.
What to look at before you approve each stage
At Buildryt, quality sign-off is required before the next stage starts, and test reports and check sheets are filed in the app before you approve. Whoever builds for you, this is a useful habit. A simple version:
| Stage | What you look at before saying yes |
|---|---|
| Foundation | Bar sizes and spacing against the drawing; cover blocks in place; cube samples taken |
| Slabs | Shuttering levels; curing started and kept wet; cube reports on their way |
| Masonry | Plumb and line; openings at the drawn positions; no dry units laid |
| Rough-in | Plumbing pressure-test record; electrical points marked as you chose |
| Waterproofing | Flood-test photos or video of terraces, bathrooms and balconies |
| Finishing | Tile levels and hollow-sound check; doors and windows aligned |
Because each stage starts only after you approve the previous one, and its payment falls due then, you are never far ahead of the work, and you always have a moment to ask questions. Take it.
What slows a house down (and what you can control)
- Sanction delays. Mostly outside your control; start early and keep documents ready.
- Monsoon. Excavation and slab casting are harder in heavy rain, so plan around June to September.
- Design changes mid-build. Fully in your control. Freeze layout and electrical points before the first slab.
- Late approvals and payments. Fully in your control. The next stage waits for your approval and its payment.
- Material shortages. A good site manager orders ahead.
What to ask your builder
- Can I see the master schedule and the stage list with durations?
- Who approves each stage, and what checks are done before it starts?
- When is the earliest I must freeze electrical and plumbing points?
- What happens to the schedule if it rains for two weeks?
- Is there a delay clause in the agreement, and what does it say?
How Buildryt runs its stages
According to buildryt.com, builds follow a master schedule with regular updates and a contractual penalty clause that holds Buildryt accountable for delay. Buildryt does not publish a fixed build duration, so the ranges above are not its commitments; ask what your agreement says. Each stage starts only after you approve the previous one, and its payment falls due then. Cubes from every slab, beam and column pour are tested at an NABL-accredited lab, with reports in the app. The app keeps you updated daily, with reports also sent to WhatsApp. Timelines for approvals depend on the local authority. See how the checks work, compare packages or check costs by size.

Frequently asked questions
What are the stages of house construction in Bengaluru?
Design and soil test, plan sanction, site marking, excavation, foundation, plinth, columns and slabs for each floor, masonry, electrical and plumbing rough-in, plastering and waterproofing, flooring and joinery, painting and fittings, then snagging and handover. A G+1 house is often planned at 9 to 12 months on site after sanction, a typical planning range that varies by site, weather and approvals.
How long does the foundation stage take?
As a typical planning range, varies by site, weather and approvals, foundation work on a G+1 house on a regular plot is often planned at about 3 to 5 weeks after excavation. This is not a promise or a Buildryt commitment. Your structural engineer's foundation type, the soil and the rain decide the real number.
How many days should concrete be cured?
IS 456:2000 clause 13.5.1 asks for at least 7 days of moist curing for ordinary Portland cement concrete, and at least 10 days where mineral admixtures or blended cements are used or in hot, dry weather. Follow your engineer's instruction on the exact period for your pour.
Why is plumbing tested before the walls are closed?
A pressure test finds leaks while pipes are still visible and cheap to fix. After plastering and tiling, repairs mean breaking finished walls and floors. A good site tests lines first and keeps the test record. Ask to see it before pipes are concealed.
Can I change the design after construction starts?
You can, but each change costs money and time, and structural changes need the engineer's approval. Freeze the layout, window positions, and electrical and plumbing points before the first slab is cast. Late changes are the most common reason for budget and schedule overruns.
