Most people can picture their finished house perfectly, but it's everything in between that's a blur, and that's usually where the stress comes from.

‍

A build moves through a set sequence of stages, each with its own start, finish, progress payment, and decisions that need making before the trades show up, not while they're standing around waiting.

‍

Here's what each stage involves, and what to be thinking about along the way.

Site preparation and base

The site gets cleared and set out, then excavation, cut and fill, services, drainage and the slab or footings go in.

‍

More unpredictable here than people expect. Sloping blocks need extra retaining and earthworks; sandy coastal soils and reactive clays need different footings, which is why the soil report matters so much; narrow coastal streets can limit truck and excavator access. It's also the stage most exposed to weather, since a wet winter can hold up earthworks and pours in ways later stages just don't feel.

‍

Settle by now: the engineering and site plan, completely. Changes here are the most expensive, since they ripple through everything after.

Frame

The frame goes up and the house stops being a drawing: walls, floor structure, roof trusses. Clients tend to enjoy this stage most, since progress is visible daily and the rooms finally feel real-sized.

‍

It's also your last easy window for certain changes. Moving a window or doorway is simple while it's still timber, but once services are run and cladding's on, it's a demolition job. A frame inspection happens before the build proceeds, with services rough-in to follow once the roof is on.

‍

Settle by now: window and door positions, and any structural changes you're still weighing up. Walking the frame with your builder is the best way to sense-check room sizes and openings against the plan.

Lock-up

Roof on, windows and doors in, cladding or brickwork done: sealed and weathertight.

‍

This matters more on a coastal site than an inland one, since everything inside is exposed to salt air and driven rain until the envelope closes. It's usually the largest single progress payment in a standard contract, worth knowing when planning lender drawdowns.

‍

This is also when we walk the house with you for the electrical layout, once the roof is on and before the plaster goes up. Every power point, switch, light, data point and appliance position gets marked up on site, room by room. Standing in the actual space beats reading it off a plan, and it's the last comfortable point to move anything before the walls close in.

‍

Settle by now: your electrical plan in full detail, plus external colours, cladding, roofing and window finishes. Internal selections should be final or close, since the next stage burns through them fast.

Fixing and internal fit-out

The longest, least photogenic stage, and the one where the house starts feeling like a home. Insulation, plasterboard, cornices, skirting, architraves and internal doors, then joinery, tiling, benchtops, painting, and finally tapware, fixtures and appliances.

‍

The sequencing here is tight. Joinery takes weeks to measure and manufacture, so it's ordered well ahead. Tiling happens before some jobs and after others. Painting comes in waves. One delayed selection can leave several trades idle.

‍

Settle by now: everything: tiles, tapware, joinery finishes, handles, benchtops, paint, flooring, lighting. Late selections are the single biggest cause of delay we see, and they're entirely within the client's control.

Practical completion and handover

The house is finished and ready to live in. You walk through with your builder, a defects list gets compiled and fixed, certification is issued, and the keys change hands.

‍

Take the walkthrough seriously: open every cupboard and drawer, run every tap, test every switch. Small things are far easier to sort now than in six months.

‍

You should leave with your certificate of occupancy, warranties, appliance and system manuals, and details of your defects liability period. That period isn't a formality: it's your window to flag anything that shows up once you're actually living there.

What actually determines how long it takes

Build time on the Peninsula depends on the site more than most people expect. A flat, sewered block with easy access behaves nothing like a sloping site with retaining, tricky access and a complex roof.

‍

The biggest factors: design complexity, the site conditions locked in at the start, weather during earthworks and lock-up, and how quickly the client makes selections. That last one is the one you actually control, and the one that most often eats up time. A decision left unmade for three weeks doesn't cost you three weeks; it costs three weeks plus whatever it takes to get that trade back on site.

Knowing what comes next

None of these stages is complicated on its own. What makes a build feel overwhelming is not knowing where you sit in the sequence, or what's being asked of you next.

‍

At TEMSEA, we spend the time to get the detail right at the start, but we understand that some things may still change along the way. We prioritise communication and involvement with our clients so we have every chance of catching every detail, while staying as organised and efficient as possible.

‍

A builder who tells you what's coming, and flags decisions before they're urgent, takes most of that stress off the table. Worth asking any builder you're considering how they keep you in the loop and how far ahead they flag selections. Our guide to choosing a custom home builder covers what else to ask, and our pre-construction checklist covers what needs resolving before any of this begins.
