Site Prep, Excavation and Foundation
The build usually starts with clearing and levelling the plot, marking out the layout, and digging for the foundation. Before anyone pours concrete, a soil test typically tells the engineer how much load the ground can carry — this decides whether you need simple footings or something heavier. Skipping this step is one of the most common and expensive mistakes.
Once excavation is done, the foundation goes in, followed by the plinth (the raised base that lifts the structure above ground level). Anti-termite treatment and basic waterproofing are usually handled here too. On a typical individual home this early phase can take a few weeks, but it varies a lot with soil, weather and plot size.
Get this stage right and everything above it sits on solid ground. Rushing it, or building on untested soil, is where cracks and settlement problems usually begin.
RCC Superstructure and MEP Rough-In
Next comes the RCC (reinforced cement concrete) frame — columns, beams and slabs cast floor by floor, plus the brick or block walls that fill in between. This is the skeleton of the building and usually the most visible, satisfying phase to watch, because the shape of the house finally appears.
While the structure is going up, the MEP rough-in happens in parallel: mechanical, electrical and plumbing lines are laid inside walls and slabs before plastering hides them. Conduits, pipes, drainage and electrical points all get positioned now, so decisions about switch locations, bathroom fittings and water lines are best locked in before this stage rather than after.
Concrete needs time to cure and gain strength, so there are natural waiting periods built into this phase. Trying to push finishing work onto slabs that haven't cured properly usually causes problems later.
Finishing, Snagging and Handover
Finishing is everything that turns a bare structure into a liveable space — plastering, flooring, tiling, painting, doors and windows, kitchen and bathroom fit-out, and final electrical and plumbing fixtures. This stage often takes longer than people expect because it involves many small trades working in sequence, and finish choices (tiles, fittings, paint) drive both cost and timeline.
Before you take the keys, there is snagging: walking the property to list defects — a leaking tap, an uneven tile, a door that sticks, a switch that doesn't work — so the contractor fixes them before final payment. It helps to snag in daylight and to test every tap, switch and drain yourself rather than assume they work.
Handover is the formal point where the property, along with any warranties, drawings and completion paperwork, passes to you. Holding back a small final payment until snags are cleared is a common and reasonable practice.
