What to Expect During a Home Renovation (Week-by-Week Timeline)

Here’s what really happens during a renovation, from demo to handover — with no sugar-coating.

Renovating your home is exciting—but let’s be honest, it’s also messy, noisy, and full of moving parts. If you’ve never been through the process before, you might be wondering: how long will it take, and what actually happens week by week?

Here’s a real-world renovation timeline NZ homeowners can expect, based on typical Key Interiors projects. No sugar-coating, just a clear guide so you can plan with confidence.

🛠️ Pre-Reno Phase (2–4 Weeks Before)

Before any work begins, we lock in:

• Design decisions

• Fixtures, fittings, tiles, and tapware

• Finalised scope and floorplans

• Council consent (if needed)

• Appliance and product orders

This is the most important phase. Good prep = fewer delays.

🔨 Week 1: Demolition + Site Prep

• Old cabinetry, tiles, fixtures removed

• Protective floor coverings laid

• Temporary walls or barriers installed

• Rubbish skip delivered

• Any minor framing or wall adjustments begin

Expect: Dust, noise, trades on-site from day one.

🧱 Week 2: Plumbing + Electrical Rough-In

• Plumbing pipes repositioned or capped

• Electrical wiring re-run for new lights, powerpoints, and switches

• Underfloor heating (if included) installed

• Builders complete wall framing or prep

Expect: Holes in walls and floors. It’s not pretty yet.

🧱 Week 3: GIB + Plastering

• GIB board installed

• Plastering, sanding, and wall prep

• Ceiling lines cleaned up and boxed areas completed

Expect: A lot of dust (again) and drying time. Site starts to take shape.

🧱 Week 4: Flooring + Tiling

• Subfloor or underlay prep

• Tiling begins in bathrooms/laundry

• Timber, vinyl, or hybrid flooring goes down in main areas

• Grouting and waterproofing checks

Expect: Your finish choices start to appear—momentum kicks in.

🪵 Week 5: Cabinetry Installation

• Kitchen, laundry, and bathroom cabinetry installed

• Benchtop templates taken (stone may require extra time)

• Appliance positions confirmed

Expect: The rooms begin to look like real spaces again.

💡 Week 6: Benchtops, Plumbing + Electrical Fit-Off

• Stone benchtops installed

• Tapware, sinks, vanities, and toilets installed

• Lights, switches, and fans fitted

• Final appliance install and testing

Expect: Your space is 90% complete—nearly move-in ready.

🧽 Week 7: Final Touches + Clean-Up

• Painting touch-ups, silicone sealing, trims finished

• Doors, handles, and hardware fitted

• Final site clean

• Quality assurance check and defect list reviewed

Expect: You’ll walk through the space and flag any final tweaks.

🏠 Week 8: Handover!

• You get the keys (or the go-ahead to move back in)

• We provide care instructions and warranties

• Photos taken (optional)

• You enjoy your new space!

Some smaller renovations may wrap up faster; larger projects may take 10–12+ weeks.

First, the honest caveat: that timeline is for one room

The week-by-week above describes a single-room renovation running cleanly, which is a fair picture of a kitchen or a bathroom where nothing unexpected turns up. It is not what a whole-house project looks like, and the gap between those two is where most disappointment lives.

Rough guide for Auckland, counting time on site only:

• Bathroom: around 3 to 5 weeks. Short, but intense, and you lose the room completely.

• Kitchen: around 4 to 8 weeks, with the cabinetry lead time usually setting the pace rather than the labour.

• Laundry: often 2 to 3 weeks, and frequently bundled in with another room because mobilising trades for a small space alone is inefficient.

• Full home renovation: commonly 4 to 6 months on site, and longer on a character home with structural work.

• Extension: add foundations, framing, roofing and weathertightness, and you are usually looking at 5 to 8 months.

The invisible half nobody puts in the timeline

Here is the part that surprises people most: on a typical Auckland renovation, more calendar time passes before site works start than during them.

Before week one of demolition you have:

• Design and documentation, typically 4 to 10 weeks depending on complexity and how quickly decisions get made.

• Pricing and contract, another 2 to 4 weeks.

• Consent. Councils have 20 working days to process a building consent, but that clock stops every time they request further information. A clean application often lands close to it; an incomplete one can drift for months. Resource consent, if a character overlay applies, runs on top.

• Long-lead ordering, which should start the moment the design is locked, not when the site is ready.

Add it up and a kitchen that takes six weeks to build has often taken four or five months from first conversation to finished room. That is normal. It only feels like a delay when nobody said so at the start. Our consent guide covers that part properly.

What actually causes delays in Auckland

Almost never the thing people expect. In order of how often we see it:

1. Decisions not made. The single biggest cause. A tile not chosen, a tapware finish not confirmed, a handle still undecided. Trades work to a sequence, and one undecided item can idle a whole week.

2. Long-lead items ordered late. Custom cabinetry commonly runs 6 to 10 weeks from sign-off. Stone benchtops are templated only once the cabinetry is physically installed, then fabricated. Imported tiles and specialty tapware can run longer. None of that can be compressed by working harder.

3. Consent RFIs. See above.

4. What is found once things are open. Rot, borer, failed waterproofing, asbestos, old wiring, cracked drains, floors well out of level. On a villa or bungalow this is close to a certainty rather than a risk.

5. Subtrade availability. Plumbers, electricians and tilers are booked weeks ahead. Miss your slot in the sequence and you wait for their next one, which is rarely tomorrow.

6. Variations. Changing your mind mid-build costs more time than money. Moving a power point after the linings are on is a small charge and a big reschedule.

Order these the day the design is signed off

If you do nothing else with this article, do this. These are the items whose lead times set your finish date:

• Custom cabinetry and joinery

• Appliances, especially anything integrated or imported

• Tapware and sanitaryware in a specific finish

• Tiles, particularly handmade or imported ranges where a re-order means a new batch

• Windows and exterior doors if the design touches them

• Flooring

Stone benchtops are the one you cannot pull forward, because templating physically requires the cabinets to be in. Build that pause into the plan rather than being surprised by it.

Why a villa or bungalow takes longer

Character homes add time in three predictable places, and a programme that ignores them is fiction.

Discovery. Old houses hide things. Floors out of level, piles needing replacement, wiring that has to be redone, drains that have failed. Good practice is to investigate before pricing so this is known rather than found, but some of it only appears once the linings are off.

Resource consent. If you are inside a Special Character Area, that runs before or alongside building consent and it is the long pole.

Making good around original detail. Matching a hundred-year-old architrave profile, scribing new work to an out-of-square wall, restoring rather than replacing. It is slower than working to a modern straight line, and it is the reason the result looks right. See our villa renovation guide.

Living through it

The practical question everyone asks last and should ask first.

• Single room, you can usually stay. A bathroom reno with a second bathroom in the house is manageable. Without one, it is a hard few weeks.

• Kitchen, you can stay, but set up properly. Move the fridge and microwave somewhere usable, accept you will be eating differently for a month, and plan for it rather than discovering it.

• Whole house, most people move out. It is faster and cheaper overall, because trades can work without protecting and unprotecting the house daily, and there is no negotiating around bedtimes. Budget for the accommodation in the project, not as a surprise.

• Dust travels further than you think. Proper containment helps, but it does not eliminate it.

• Working hours. Most sites run roughly 7am to 4pm on weekdays, and it is noisy.

How to protect your timeline

1. Lock the scope before anyone starts. A clear, fixed scope beats a fast start every time.

2. Make every selection up front, down to the handles. Every open decision is a future delay.

3. Order long-lead items immediately.

4. Resist mid-build changes. If you must change something, ask for the time cost as well as the price.

5. Have one point of contact who owns the programme, rather than coordinating trades yourself.

6. Expect a contingency, in time and money. On a character home, plan for both.

We run fixed-price, single-team projects with the programme managed for you, which is what keeps these timelines honest. See our design and renovation services, or browse real projects in our before and afters.

Frequently Asked Questions

How long does a typical renovation take in NZ?
Most mid-size renovations (kitchen, bathroom, laundry) take 6–8 weeks. Larger or structural projects can run 10–14 weeks or more depending on complexity.

Can I live in the house during the renovation?
Sometimes—if the renovation is contained to one part of the house. But expect disruption, noise, and dust. Many clients temporarily move out if multiple rooms are involved.

What causes delays in renovations?
Late product orders, unforeseen wall/floor issues, or decision changes mid-build. That’s why we lock in all selections up front.

Do I need council consent for my renovation?
Only if structural, plumbing, or layout changes affect compliance. We’ll advise you during the planning stage if consent is needed.

Can you manage the whole renovation for me?
Yes—we handle everything from design to delivery, so you don’t have to coordinate trades, suppliers, or council paperwork.
