What a kitchen design process looks like, step by step

Hiring a kitchen designer can feel like handing over the keys to the most expensive room in the house. It helps to know what a sound process looks like before you start. Whoever you work with, whether an independent designer, a cabinetmaker with a design service or an architect, the good ones move through broadly the same stages. Each stage ends with a decision you sign off, so mistakes get caught on paper rather than in plywood.

Here is how that sequence usually runs, and what you should be doing at each point.

1. The brief

Everything rests on the brief, which is really a written answer to "how do we actually live?" Before the first meeting, jot down:

• Who cooks, how often, and whether two people cook at once.
• What frustrates you about the current kitchen: no landing space beside the oven, a pantry you can't see into, a bin with nowhere to live.
• What has to stay, such as a window, a chimney breast or a sink that sits on a drain you don't want to move.
• Your budget as a range, plus a contingency. Setting aside 10-20% for surprises is common advice for renovations, and older houses tend to need the top end.
• Timing: when you can live without a kitchen, and any fixed dates.

A good designer will push back on the brief with questions. That is a sign they are listening, not upselling.

2. Site measure

Next comes a measured survey of the room. Expect the designer to record wall lengths, ceiling height, window and door positions, and where the existing plumbing, waste, power and any gas or ventilation sit. They should also note walls that are out of plumb and floors that are out of level.

This is the moment to raise anything hidden: a soft patch of floor near the dishwasher, a damp smell under the sink, wiring you suspect is old. Problems found now cost far less than problems found once the old cabinets are out.

3. Concept design

The first drawings are usually a floor plan and a few elevations or 3D views showing layout options. At this stage you are judging the bones: where the sink, cooktop and fridge go, how people move through the room, and how much bench and storage you get.

Resist the urge to pick handles yet. Ask instead:

• Can two people pass each other while the dishwasher door is open?
• Is there clear bench space either side of the cooktop and next to the sink?
• Where do the groceries land when you walk in?

4. Revisions

Most processes allow a set number of revision rounds before extra fees apply. Check how many are included and what counts as a revision. Bring your feedback in one consolidated list rather than in dribs and drabs, and be specific: "the island feels too close to the fridge" is more useful than "something feels off".

Problems found on paper cost far less than problems found once the old cabinets are out.

5. Detailed specification

Once the layout is settled, the design becomes a specification: final drawings plus a schedule listing cabinet construction, carcass and door materials, benchtop, splashback, hardware, appliances, sink and tapware, lighting and power positions. This is the document trades will price and build from, so read it closely.

Look for gaps. If an item says "TBC" or "allowance", you are carrying the risk that it costs more than expected. Check appliance model dimensions against the cabinet openings, and make sure power points, the rangehood duct route and the dishwasher's water and waste are actually drawn rather than assumed.

6. Consents, where relevant

Many kitchen renovations don't need a building consent, but some do, and the line isn't always obvious. Building.govt.nz's guidance on plumbing and drainage work that doesn't need a building consent explains that altering existing sanitary plumbing can be exempt where the number of sanitary fixtures doesn't increase, and the work is done by an authorised person. Remodelling a kitchen within the same space, with the sink staying put, is the kind of job that commonly falls within the exemptions. Adding a new kitchen, adding fixtures, or structural changes such as removing a load-bearing wall are different matters.

Two points are easy to miss. First, exempt work must still comply with the Building Code. Second, plumbing, gasfitting and drainlaying have to be done by appropriately authorised people, and electrical work generally needs a licensed electrician. If you're unsure, ask your council before work starts. It can grant a discretionary exemption or tell you a consent is needed.

7. Pricing and contracts

With a full specification you can get comparable quotes. Consumer NZ's guide to choosing tradies and builders is a useful primer. It covers the difference between an estimate and a quote, the main contract types, and why you should get everything in writing. For residential building work above a set value, NZ law requires a written contract and certain prescribed information, so ask for both.

Pay attention to variations. Any change after the contract is signed should be instructed and priced in writing before the work is done. That is where many kitchen budgets quietly drift.

8. Trades and sequencing

A typical sequence looks like this, though every job differs:

1. Strip-out of the old kitchen.
2. Any structural, framing or subfloor work.
3. Rough-in of plumbing, drainage, electrical and ventilation while walls are open.
4. Linings, plastering and painting of walls and ceiling.
5. Flooring, if it runs under the cabinets.
6. Cabinet installation.
7. Benchtop template and install. Stone and solid-surface tops are usually templated on site after the cabinets go in, which adds a gap of days or weeks.
8. Splashback, final plumbing and electrical fit-off, appliances.

Ask your designer or main contractor who coordinates this sequence. Often it is a project manager, a builder or the cabinetmaker, and it is worth confirming in writing.

9. Install, snagging and handover

At practical completion, walk the kitchen with the plan in hand and make a list: doors that don't align, drawers that catch, a missing kickboard, silicone that isn't finished. Agree a date for fixing the list. Collect appliance manuals, warranties, care instructions for the benchtop, and any code compliance or producer statements that apply.

The short version

A kitchen design process is a series of narrowing decisions: brief, measure, layout, refinement, specification, approvals, pricing, build and check. Sign off each stage before moving on, keep changes in writing, and spend most of your thinking time on layout and specification. Those are the two stages that shape everything else.
