Two quotes for the same kitchen can differ by 60% and both be honest. Here is where to look. None of what follows depends on style or budget tier; it applies whether the room is being done on a tight number or a generous one. What changes with budget is the material, not the sequence of decisions. This is written from projects rather than from a general principle, which is why it names specific dimensions and specific failure modes rather than staying at the level of advice. Where your own room differs from the assumption behind a point, the point still applies — just adjust the number. Nothing here requires taking our word for it; each point is the kind of thing you can verify yourself on a site visit or ask a contractor to confirm in writing. That verification is usually the difference between advice that gets followed and advice that gets nodded at and ignored. A few of these points contradict what gets repeated as conventional wisdom. Where that happens we say so directly and explain why, because the conventional version is usually true in general and wrong for the specific case it gets applied to.
We raise this early in every project for the same reason it is worth raising here: it is cheap to decide correctly up front and expensive to correct once the trades that depend on it have moved past it. Where any of this does carry a cost, it is usually smaller before installation than after. A change raised at the drawing stage is a line on a plan; the same change raised after the trades that depend on it have moved past it is a demolition and a delay. Most of what follows needs deciding before the trade it depends on starts, not before the project starts — so there is usually more time to get this right than it first appears, provided the decision does not get skipped until that trade is already on site.
Compare the material schedule, not the total
A quote without a line-by-line schedule of carcass material, shutter finish, hardware make and countertop cannot be compared to anything. Ask for it before you look at the number.
Check what unit the pricing is in
Running foot, square foot of shutter area, and per-module pricing all produce different totals for identical work. Make both quotes state the same basis.
Find the exclusions list
This is where the difference usually lives — electrical rework, civil changes, painting, transport, installation, loading and society charges. A quote with no exclusions list is incomplete, not inclusive.
Look at the hardware line specifically
Hinges and runners are 5-8% of cost and the first thing to fail. A quote that says 'imported hardware' without a make and cycle rating is hiding the cheapest available.
Ask what triggers a revision
Understand which changes are free, which are chargeable, and at what point the price is locked. Get that in writing at sign-off rather than discovering it at production.
Summary
Key takeaways
Reduced to a checklist, this is what to carry into a conversation with a designer:
- Compare the material schedule, not the total
- Check what unit the pricing is in
- Find the exclusions list
- Look at the hardware line specifically
- Ask what triggers a revision
The fastest way to know which of these apply to your room is to put a floor plan in front of a designer rather than guess from an article, however carefully written. This article is one piece of a larger project rather than a standalone decision. Where it touches layout, storage or services, it connects to the design categories on this site that carry the full specification — worth reading alongside this one rather than instead of it.
Questions
About expert advice
Does this apply to a resale flat as well as new construction?
Yes, with one difference: in a resale flat we verify what is actually behind the wall or ceiling before relying on it, since the original drawing is often no longer accurate to what was built or altered.
How much does getting this right or wrong actually cost?
Usually far less to get right at the drawing stage than to fix after installation. Most of what is covered here is free to change before sign-off and expensive to change after, which is the whole reason it is worth deciding early.
Is this something I can plan myself, or do I need a designer?
You can plan the intent yourself; a designer earns their place in translating it into a drawing the factory and the site can execute without ambiguity, and in catching the version of this that does not suit your specific room.
Does this apply outside a full renovation — say, a single-room refresh?
Yes. Most of what is covered here is scoped to one room or one decision rather than to a whole-home project, and applies just as directly to a smaller scope.
How confident should I be applying this without a site visit?
Confident enough to plan around, not confident enough to finalise a drawing from. Every point here is a starting assumption that a measured survey either confirms or adjusts — treat it as the question to ask, not the final answer.
Where can I see this specified in full for my own room size?
The design category and home-size pages linked below carry the full buildable specification — layout, material, dimension and cost — for the decision covered in this article.
