Decision readiness
Kitchen and utility
The kitchen is the heart of the home, and getting it right goes beyond cabinets: brief, timing, coordination and cost.

The kitchen is the heart of the home, and most families build their day around it. Getting it right means more than choosing units and a worktop: it means thinking about how your family gathers, how the room connects to the rest of your home, and locking in the decisions that have to happen early in your project before you walk into a showroom or choose colours.
Where do you start when you're planning a kitchen?
Start with how your family gathers, not with aesthetics. Most kitchens now sit within a semi-open-plan space, with a seating area, a dining table, or both. How the kitchen connects to those spaces and the outside shapes the spatial design before any units are chosen.
Write down your vision for how people will interact in the space. Reflect on whether you are a social cook who wants people gathered around an island, or would prefer to chat with friends without your cooking being on show?
These decisions lead to different kitchens and need to be baked into your layout and flow thinking before plans are signed off, because they can affect the kitchen's orientation and position within the property. If the island looks out over the garden, that orientation needs to be decided before the room is built.
Underneath all of this sits a useful frame: the working triangle. Hob, sink and fridge are your three working points, and the distances and obstructions between them determine how the kitchen works in use. Test any layout against this before committing to it: where appliances sit, whether an island makes sense, how seating is oriented.
Your utility needs the same early thought as one of the hardest working rooms in your home. Decide what yours is for before you plan it: laundry, overflow kitchen, pet space, or a combination. The same applies to a walk-in pantry: how you shop, how much you cook, and how much you want on show all matter.
What has to be decided before first fix?
A kitchen involves more trades than almost any other room: plumbers, electricians, kitchen fitters, decorators, flooring teams. Making all key decisions early will make scheduling and installation much easier.
If you want an American fridge freezer, the water feed needs to go in before the screed is poured on a new build floor. Sink and dishwasher positions need settling early for drainage. Hob choice, gas, electric or induction, determines gas supply, electrical load and extraction route.
Kitchen plans are a second layer of drawings beyond your architect's site plans, produced by a kitchen designer, an interior designer or the kitchen company. These plans detail the exact placement of every unit, every water feed and every electrical feed. Contractors on site need these plans as the kitchen area is being built, so first-fix electrics and plumbing land in the right place.
If you want your worktop to run into a window recess, this decision needs making early. It impacts windows and screed levels. That kind of detail only happens with good planning.
On one project, the flooring height was agreed with the contractor so the worktop could run seamlessly into the window recess. The worktops were a bespoke height for the client, so this needed careful discussion and communication on site to ensure it fitted properly.
Running the worktop into the window recess gives a clean finish around the sink
If you are having solid worktops, build the gap into your programme: templating happens once base units are fitted, which adds two to three weeks between cabinets going in and worktops being installed.
Lighting needs its own layered plan: task lighting over the hob and island, ambient lighting for evenings. A grid of downlights doing every job at once is the default and rarely the right answer.
Who actually designs your kitchen?
Architects and architectural technicians vary widely in how much kitchen detail they cover. Some will design the kitchen with you in real detail, so by the time you have plans the island, seating orientation and cupboard space have all been decided. Others will place a rough layout to show how the space could work, without it having been considered specifically in detail.
Kitchen companies generally won't do spatial design in terms of proposing to move walls or relocate the kitchen. That's typically outside their commercial scope. They organise units within the space you give them and advise on appliance layout. Recognise this, so you don't arrive expecting full spatial design.
Before you move into detailed kitchen plans, check you are happy with the size, position and orientation of your kitchen. If you are unsure, get some advice from an interior designer.
On site, the main contractor is usually responsible for electric and plumbing feeds, and the kitchen company manages installation. Getting the kitchen company out to review first-fix positions against their own drawings, once first fix is in, catches problems while they are still cheap to fix. If your builder is supplying and fitting the kitchen, this collapses to one point of responsibility.
Where does the kitchen budget really go?
Cost is driven by cabinetry, appliances and worktops, in roughly that order. Kitchens range from fully bespoke handmade joinery to modular off-the-shelf ranges.
Decide your overall interior fit-out budget before settling on a kitchen brand. Homeowners routinely underestimate bathroom fittings, bespoke joinery, flooring, lighting and loose furniture, and overspend on the kitchen as a result. The kitchen budget decision belongs after you have ballparks for everything else.
There are real saves available. In a very large kitchen, consider avoiding corner cupboards altogether, as they are awkward and often less useable spaces.
On a recent project with a large kitchen, we decided the corner cupboards were not required for storage so removed them from the design. This enabled the units to have better use, and avoided awkward corner pull-out trays or difficult-to-reach spaces.
Changing door finishes can transform how a kitchen looks without going fully bespoke. Pull-out and foldaway doors have been on trend recently, but these elements can be very expensive, so ensure budget and design choices align. Decide consciously whether that is where the spend should go.
If your builder has quoted with a PC sum for the kitchen and you decide to source it yourself, removing it is not a clean subtraction. Builders build profit margin into their contract price, and that conversation needs to happen directly to ensure both parties are comfortable with how that changes the contract.
Repositioning a kitchen can cost less than people assume. If a fixed plumbing or drainage position looks like it rules out a better layout, check it with your contractor and get a ballpark quote. The cost to move a kitchen can be an investment well worth making if it significantly improves the overall layout and flow of your home.
What goes wrong with kitchens?
The most consistent starting mistake is going to a kitchen showroom before the floor plan is right. Get the layout settled first, understanding connection to the rest of the home and where key appliances will be positioned, and then brief the kitchen company once those elements are decided.
The second is not being realistic about how you actually live. Brochures show an island with a sink but none of the pots stacked up waiting to be washed, a hob but none of the chopping board chaos. Think through how you cook and clean up before committing. If space allows, moving the hob and sink off the island and onto perimeter worktop leaves the island free for prep and changes the feel of the room day to day.
Storage is often underplanned. Think through what the kitchen actually needs to hold, and if it feels tight, consider whether items used less often, large serving dishes, lasagne pans, seasonal kit, could live somewhere adjacent instead of inside the kitchen.
Another is ignoring how people move through the room. A kitchen that doubles as a through-route needs its cooking zone kept clear of the traffic path.
On one project, the kitchen was also the route through to the dining area. Appliances were planned around that path, so the hob and active cooking zone sat on the side away from the main flow.
In a kitchen you walk through, the cooking zone sits away from the main traffic path
Committing the kitchen budget before you know what the rest of the interior costs is its own recurring mistake. Get ballparks for bathrooms, flooring and joinery before the kitchen number is fixed.
Kitchens are often fitted right at the end of the project, when everyone on site is ready to finish, and you are desperate to get into your new home. Ensure you don't rush this final stage. Give the kitchen fitter the time needed to produce the finish you want; a tight, unrealistic deadline shows in the result.
How do you make the kitchen decor work with the rest of the home?
If you did the thinking at the Preparation stage, you will already have a base palette direction for flooring, doors, windows and walls. Kitchen finish decisions sit against that.
The kitchen's largest finish is the units, and they sit against the flooring. A wooden kitchen with oak doors against an oak floor is hard to pull off well and needs to be a deliberate choice with wood tones considered.
Worktop material carries real cost, durability and aesthetic differences across quartz, granite, marble, solid surface, wood and ceramic. If you are having a waterfall effect on the island, the finish will again meet the flooring, so ensure you have sufficient contrast, but that it works as part of the overall decor scheme.
Finish preferences may impact the kitchen company or designer you work with, and also have a cost implication. A hand-painted in-frame shaker kitchen will be a different design approach to laminate slab doors. Kitchen companies specialise differently: some in wood veneers, others in spray paint, others in laminate, so look at past projects and ensure they offer the range of finishes you like.

Frequently asked
When should I start planning my kitchen?
Well before you appoint a kitchen company, and ideally while your architect is still working through layout before planning approvals. Many kitchen decisions, particularly where it sits in the home and how it connects to adjacent spaces, have to feed back into plans before they are signed off.Do I need an interior designer, or can the kitchen company handle the design?
The kitchen company handles units, appliances and finishes within a space you give them. If no one has worked through the spatial questions, whether there should be an island, how the room connects to other spaces, where walls or openings should sit, that gap is where an interior designer adds the most value. If you are not using one, ask whether your architect has covered that ground with you in detail.What should I budget for a kitchen?
Settle your whole interior fit-out budget before putting a number on the kitchen. Bathroom fittings, bespoke joinery, flooring, lighting and loose furniture all compete for the same pot, and kitchens are where homeowners most reliably overspend relative to what is left for everything else. Cost is driven by cabinetry, appliances and worktops.Can a kitchen be moved if the plumbing is already in place?
Sometimes more easily than people assume. The cost of redirecting water feeds is often smaller than expected. Underfloor heating in an existing kitchen is one thing that can make relocation a real issue, along with limited plumbing feeds. An existing drain position doesn't automatically make a new location impossible, so discuss it with your contractor.What is the most common mistake with kitchen islands?
Forcing an island into a narrow kitchen is an issue, and sometimes it's not the best solution for your home. Also not being realistic about how you cook. Brochures show clear worktops and tidy sinks; real life accumulates washing-up and prep mess. Where the layout allows, consider keeping the hob and sink on perimeter worktop and leaving the island for prep.When do hob and worktop decisions need to be locked?
Both earlier than most people expect. Hob type determines gas or electrical supply, electrical load and extraction route, all of which affect first-fix planning. Worktop decisions can come slightly later, but cost for your worktops early as they can be a significant part of the kitchen budget. In terms of timing, solid worktops will be templated after base units are installed, adding a two-to-three week gap between cabinets going in and worktops fitting.Do I need to plan the utility at the same time as the kitchen?
Yes, the utility can be the hardest working room in your home, and often sourced from the kitchen company, so do it at the same time. Working out the main use of the space such as laundry, second kitchen, pet space, or all three, helps to ensure the room is functional.
