What actually happens on site.

Building is mostly waiting for the right thing to be ready.

The common expectation is that a house rises steadily — a bit more each week until it is finished. What actually happens is a sequence of trades, each of which cannot start until the one before it has finished and been inspected. Progress therefore arrives in bursts separated by periods where the site looks idle and is not.

Understanding this changes how you read your own project. The week when nothing visible happens is often the week that decides whether the next three go well. The following is what actually occurs, in order, and what is genuinely required of you at each point.

Before anything is built.

Site establishment: hoarding, access, welfare, storage, power and water, safety signage, and the approvals to have people on the plot at all. In a gated community this also means the community’s own permissions — working hours, access routes, deposits, and often a schedule agreed with neighbours.

Then setting out: the house is marked on the ground against the approved drawings and the plot boundaries. This is worth attending. It is the first moment the design becomes a size you can walk, and the last moment a room can be moved for the cost of a conversation.

Substructure — the part you cannot see and cannot revisit.

Excavation, foundations, ground treatment where required, below-ground drainage and waterproofing. Every element here is permanent in a way nothing else on the project is: it is buried, inspected, and then built upon.

This is also the stage where the discovered block of a budget usually declares itself — ground conditions differing from the survey, existing services in unexpected positions, or a neighbouring structure closer than the drawings suggested. Expect a conversation here. Be suspicious of a project that reports no findings at all.

Superstructure — the weeks that look like progress.

Columns, slabs, walls and roof. This is the fastest-moving and most photogenic stage, and the one clients enjoy most, because the house appears. It is also when the least is being decided: almost everything about this stage was fixed months earlier on paper.

The critical work during these weeks is not on site. It is the procurement and shop-drawing programme running alongside it — joinery being drawn, stone being selected, sanitaryware ordered, long-lead items placed. Items ordered late during superstructure become the delay that appears at finishing, when it is visible and expensive.

First fix — the most important stage nobody photographs.

Electrical containment, plumbing, drainage, air conditioning ducts and pipework, and the openings and penetrations they require, all installed before anything is closed up. Followed by inspection, and by the civil defence and utility approvals that depend on it.

Two things matter here more than anywhere else on the project. First, this is the point of no return for layout: after first fix, a socket, a tap or a wall costs a multiple of what it cost the week before. Second, this is where quality is genuinely decided. A house is only as good as what was buried in it, and the difference between a well-built and a poorly built villa is almost entirely invisible after this stage.

If you visit once during the whole build, visit at first fix.

Closing up and second fix.

Blockwork completed, plaster, screeds, tanking to wet areas, then the finishes: tiling, stone, joinery installation, sanitaryware, ironmongery, painting, lighting and the trims that make a house look finished.

The programme becomes congested here because many trades must work in the same rooms in a specific order, and each depends on the last being complete and clean. This is where a well-coordinated project pulls decisively ahead of a poorly coordinated one — not through speed, but through sequence. It is also where late client decisions do the most damage, because a single undecided item can hold a room and everything queued behind it.

Commissioning, snagging and handover.

Systems are tested and balanced: air conditioning, water, electrical, drainage, fire and any specialist installations. Then snagging — a systematic inspection producing a single written list of defects, closed one by one with evidence rather than assurance.

Then the closing sequence: completion certification, permanent utility connections and community clearances. Homes have stood finished and uninhabitable for weeks because this stage was treated as paperwork rather than as construction. Ask early who owns it by name.

What is genuinely required of you.

Less than clients fear, but at specific moments. Decisions on specification before they are needed rather than when they are urgent. Attendance at setting out and at first fix. Prompt responses when a discovery requires a choice — a week of deliberation on site is a week of programme. And attendance at snagging, because it is your list and nobody else will notice what you notice.

What you should expect in return is a written programme, a report on a fixed day whether or not there is news, and an honest account when something goes wrong. Silence during a build is almost never a good sign; it usually means nobody has been given the job of telling you.
