What level of architectural service does your project actually need?

Why fees vary, and how to spend well rather than simply spend less

Anyone comparing architects quickly runs into the same puzzle: the fees vary enormously, and it is rarely clear why. One proposal comes in well below another for what looks like the same work. Without a way to understand the difference, it is tempting to treat the lowest number as the best value - and that is where projects often go wrong.

The more useful question is not how to pay the least, but how to spend well: how to match what you pay for to what your project genuinely needs, and how to avoid the far larger costs that come from starting in the wrong place.

Why fees vary so much

Architect fees vary because scope varies. Two proposals for the same house can describe quite different levels of service, even when the drawings at the end might look similar.

A lower fee usually reflects a narrower service - fewer design options explored, less resolution of the details, less coordination with engineers and other consultants, less involvement once the work reaches site. A higher fee usually reflects a fuller service - more time spent testing the design, more detailed information for the builder, closer oversight during construction. Neither is wrong. They are answers to different questions, and the right one depends on your project, your budget, and how much of the process you want to hand over rather than manage yourself.

As a rough guide, architect fees for a residential project typically fall between 12 and 15 per cent of the construction budget, with the wider consultant team - structural engineer, party wall surveyor, building control and others, reaching perhaps 20 to 25 per cent in total. But the percentage matters less than what sits behind it. A fee is only meaningful once you understand the scope it represents. Comparing two fees without comparing the two scopes could lead to disappointment as you later discover what is not included.

Why the fee is the small number

There is a further point that fee comparisons almost always miss. The architect's fee is a small proportion of the total cost of a project - and how well that fee is spent has a direct effect on the much larger numbers around it.

The construction cost, the wider consultant fees, and the VAT that sits on top of both together dwarf the architect's fee. What connects them is risk. When a building is documented thoroughly - complete, well-coordinated drawings and clear specifications - a builder can price it with confidence, because there is less uncertainty to allow for. Less uncertainty means a keener price, because the builder is not adding a margin to cover the unknowns. During construction, fewer things are left undefined, so there are fewer variations, fewer delays, and fewer of the expensive decisions that get made on site when a drawing did not answer the question.

The reverse is also true. A project documented too thinly - often because the fee was too low to allow the work to be resolved properly - pushes cost outward. The builder prices the uncertainty. The gaps surface later as variations, usually at a worse price than if they had been designed in from the start. The saving on the fee is frequently smaller than the extra cost it creates everywhere else.

This is why a good investment into a professional team can, paradoxically, reduce the total cost of a project. The fee is not the number to minimise. It is the number that, spent well, brings the far larger numbers down - by removing risk before it becomes expensive.

Matching the service to the project

Architectural involvement is not all or nothing. It exists on a spectrum, and part of spending well is choosing the right point on it for your particular project.

Some projects need the full service from first sketch to final handover - complex work, unusual sites, listed buildings, or simply clients who want the whole process handled with care and continuity. Others need less. A confident client working with a capable builder on a straightforward project might need design and planning drawings but choose to be less involved during construction. A smaller project might need guidance at a single stage rather than the whole journey. Matching the level of service to what the project genuinely requires is not cutting corners. It is spending where it counts and not where it does not.

The point worth holding onto is that a lower fee for a narrower service can be entirely the right choice - as long as you understand what has been narrowed, and are confident that the parts left out are parts you genuinely do not need. The risk is not in choosing a lighter service. It is in choosing one without realising that is what you have done.

The biggest cost is rarely the fee

Most fee comparisons fail to identify the largest avoidable cost in the project. It is not the architect’s rate but the cost of building on a brief that was never properly tested.

Most clients begin wanting more than the budget or the space can comfortably carry. That is entirely natural - it is hard to know what is realistic before anyone has looked properly. But it means that a project which rushes straight into design, with fees agreed against a brief that has not been thought through, is built on an assumption that has not been checked. It is tempting to move quickly into design, because that is where a project feels like it is progressing. Yet if the brief has not been tested against what the budget and the site will actually allow, there is a good chance the design will need to change once reality catches up with it.

Changes are inexpensive to manage early but become more costly as the project progresses. A change of mind at the concept stage costs very little - a few lines redrawn. The same change during technical design, or once construction has begun, can be very costly indeed. In the worst case, a project reaches concept design or beyond before it becomes clear that it was never quite feasible as imagined - and by then the fees spent getting there have bought a conclusion that could have been reached far sooner and far more cheaply.

Test the brief before you commit

This is why the most effective way to spend well is to test the brief before committing to a full design service. A focused early study establishes what is genuinely achievable - reconciling what you want with what the budget and the space will allow, and often revealing that you can do more with less than you expected.

It settles the three things that otherwise cause the most expensive surprises: whether the design ambition is realistic, what the project is genuinely likely to cost, and how long it will take. With those established, you can commit to the design phase knowing the brief is sound - rather than discovering midway through that it was not. It is a modest cost that protects against a much larger one, which makes it, in effect, the cheapest insurance in the whole project.

This early stage is something I build into every project as a Feasibility Study, and I have written separately about how it works and what it produces. For the purposes of fees, the point is simply this: the study is not an extra cost on top of the service. It is what makes the rest of the spending sound.

Spending well, not simply spending less

Bringing this together, spending well on architecture comes down to a few things, and a trusted adviser to guide them. Understand what a fee actually represents before comparing it to another - scope, not just the number. Match the level of service to what your project genuinely needs, neither more nor less. And test the brief early, so that the money you commit to design is spent on a project you know is sound rather than one you hope is.

Done this way, the question stops being how to save on fees and becomes how to get the most from what you spend. The two can look similar at the outset. They tend to lead to very different places by the end.
