Most Homeowners Have No Idea What’s Happening on Site
Sign a contract, hand over an advance, and trust that something is happening on site. That’s how most people build their homes. And then month five arrives and nothing is what they expected.
Knowing the stages of construction doesn’t make you an engineer. It makes you a better client. You’ll know when to ask questions, which shortcuts to push back on, and whether the work you’re seeing actually matches what the contractor promised.
We follow a 270-day build schedule at Walls & Dreams with daily photo updates. More on how we run projects: our end-to-end construction process.
Stage 1: Site Preparation and Layout
Nothing goes into the ground until the site is ready. That means clearing the plot, levelling where needed, and getting the building footprint marked out exactly as the approved drawings show.
A layout error here gets baked into everything that follows — a wall that’s 6 inches off will misalign doors, windows, and eventually create problems with the neighbour’s boundary. It’s worth spending the time to get it right.
- Soil testing happens here — determines what kind of foundation the plot needs
- Water source arranged for construction — bore well or tanker supply
- Site office, material storage area, and perimeter fencing put in place
Duration: 1–2 weeks.
Stage 2: Foundation Work
This is the stage nobody photographs and everybody underestimates. The foundation is completely invisible once the walls go up — which is exactly why it matters so much.
In Delhi NCR, most independent homes use isolated column footings for RCC frame construction. The soil test result determines the depth and width of the footing.
- Excavation to the required depth — typically 4 to 6 feet for a two-storey home
- PCC (Plain Cement Concrete) bed laid at the base — creates a clean, level working surface
- Rebar placed and tied as per the structural engineer’s drawing
- Concrete poured, compacted with a vibrator, and left to cure — minimum 7 days with water
Ask for daily curing photos. It takes 10 seconds to take one. Contractors who don’t bother often aren’t bothering with the curing either — and cutting that short drops the concrete’s final strength by up to 40%.
Duration: 3–5 weeks depending on soil and structure size.
Stage 3: Plinth Construction
The plinth is the section of wall between the top of the foundation and your ground floor level. It lifts the floor above natural ground — important in Delhi NCR where even a single monsoon season can push groundwater high enough to damage a floor slab.
A plinth beam runs between columns at this level, tying them together. Think of it as the belt that holds the base of the structure together. Anti-termite chemical treatment goes in at this stage — once the floors are done, you can’t get it in properly.
- Plinth filling done with compacted murram or clean earth, in 150mm layers
- DPC (Damp Proof Course) layer laid to stop moisture rising from the ground
- Basement retaining wall waterproofing starts here if a basement is in the design
Duration: 2–3 weeks
Stage 4: Superstructure — Columns, Beams, and Slabs
This is when it starts looking like a building. Columns go up, beams span between them, and slabs form your floors and ceilings. For a G+1 house, this plays out twice — once per floor.
Columns
Columns carry the weight of everything above — beams, slabs, walls, and whatever’s in the rooms — down to the foundation. Formwork goes up, rebar is tied inside it, concrete is poured and vibrated, and then it waits. Formwork typically comes off after 24 hours, but the concrete is still gaining strength and needs water curing for another 7–14 days.
Beams and Slabs
Beams connect the columns and carry the slab load across to them. The slab is both your ceiling and the floor for the storey above. Centering (temporary wooden or steel support) holds everything up while the concrete is wet, reinforcement mesh is laid in, and the pour happens in one continuous go — stopping mid-pour creates a weak joint.
Every electrical conduit, plumbing sleeve, and AC drain line that needs to pass through the slab must be positioned before the pour. Miss something here and you’re cutting into the slab later — which nobody wants.
Duration per floor: 4–6 weeks.
Stage 5: Brickwork and External Walls
Once the RCC frame has cured, brick panels fill the spaces between columns. Delhi NCR builders use red clay bricks, fly ash bricks, or AAC blocks — each has trade-offs on weight, insulation, and cost.
- AAC blocks are around 40% lighter than clay brick and hold temperature better — preferred for upper floors
- Lintels (short beams) go above every door and window opening before the brickwork continues above
- Electrical conduit chasing cut into walls during or just after brickwork — before plaster goes on
Duration: 4–6 weeks per floor.
Stage 6: Plumbing and Electrical Rough-In
All the pipes and conduits that will be hidden inside walls and floors must be placed now. Once plastering happens, they’re gone — and any mistake requires wall-breaking to fix.
- CPVC water supply pipes and drainage lines set in position
- Electrical conduit runs from the distribution board to every room’s circuit points
- Bathroom trap positions and waste outlets fixed in concrete
Sit with the layout drawing at this stage and physically walk each room. Switch heights, tap positions, AC drainage outlets — confirm every point before plaster closes the walls.
Duration: 2–3 weeks.
Stage 7: Plastering
Plastering creates the flat surface that paint and tiles go onto. Standard approach is two coats — a thick base coat (12mm) then a finer finish coat (6mm) once the base has cured.
- Walls wetted before applying — dry surfaces pull water from the plaster mix too fast and weaken adhesion
- Chicken wire mesh applied at brick-to-column junctions — different materials expand at different rates and crack plaster at joints if not reinforced
- 7-day water curing after each coat — no shortcuts
Hollow plastering — where sections sound different when tapped — is a common quality failure. It means the plaster didn’t bond. These sections will crack and fall off in 2–3 years.
Duration: 3–4 weeks.
Stage 8: Waterproofing and Flooring
Waterproofing comes before tiles, not after. This order is non-negotiable and still gets skipped by lazy contractors all the time.
- Two coats of polymer-modified waterproofing on every bathroom floor — followed by a 24-hour flood test before a single tile goes down
- Floor screed laid to bring the finished floor to the correct level before marble or vitrified tile installation
- Terrace waterproofing done with brick bat coba or a modern membrane system
A bathroom that leaks through to the ceiling below costs ₹80,000–1,50,000 to fix post-possession. The waterproofing that prevents it costs ₹8,000–15,000. The math is obvious.
Duration: 3–5 weeks.
Stage 9: Doors, Windows, and Joinery
Door frames go in during brickwork so the masonry can bond around them. The actual shutters, windows, and grilles come later — right before finishing begins. Putting them in early just means construction dust and concrete splatter on new joinery.
Most homeowners in Noida and Gurgaon now go with UPVC windows over aluminium. Less maintenance, better heat resistance through Delhi summers, and they don’t let monsoon water in the way older aluminium frames do.
Duration: 2–3 weeks.
Stage 10: Paint and Final Finishes
This is the stage where it stops looking like a construction site. Wall putty fills minor surface imperfections, primer seals the surface, and then two coats of emulsion go on. On external walls, weather-shield or textured finish — Delhi NCR’s summers hit 45°C and the monsoon hammers the walls, so standard interior paint won’t survive outside.
- False ceiling framing and gypsum work done before wall painting begins
- Electrical fixtures, fans, switches, and points installed and tested
- Plumbing fixtures — taps, commodes, geysers — fitted and checked for leaks
- Full site cleaning and snag walkthrough with the client
Duration: 4–6 weeks.
Stage 11: Handover and What Comes After
Construction done doesn’t mean the relationship ends. Our WD Care programme runs 6 to 12 months post-handover with free visits and warranty coverage. Details here: how Walls & Dreams builds and cares for your home.
Before accepting the keys, ask for the full handover package: as-built drawings, waterproofing test certificates, electrical compliance reports. These matter if something goes wrong in year two.
