Why is it so hard to get a straight answer on architecture and building costs?

If you’ve ever asked an architect, “How much will this cost?” and received a vague or non-committal answer, you’re not alone and you’re not wrong to feel frustrated.

Before I go further, hands up, I used to be part of the problem – I felt pressure to speak about costs with customers because it was expected of me and really didn’t want to let my customers down. I also didn’t want to seem like I didn’t know the answer.

Many architects are uncomfortable talking about money and while that might sound surprising, there are real reasons for it. Some are practical, some cultural, and others are embedded in the profession itself. Recognising these challenges doesn’t excuse the lack of clarity, but it does help explain why cost so often gets left out of the real conversation and why so many homeowners end up feeling confused or caught off guard.

1. Why architects find discussing cost conversations so difficult.

They’re trained to design, not price.
Architects are taught to think in terms of vision, space, aesthetics and regulations, not market-driven costs. Pricing is often treated as something outside their domain and something that “the builder will work out later.”

Fear of being wrong.
Most architects like being right all the time. We’re trained that way. Many don’t feel confident estimating build costs because they’re worried about being held to those numbers later,  especially when inflation, site conditions, or contractor pricing can throw things off. So instead of giving a ballpark, they say very little (or worse) make a guess under pressure that turns out to be far off the mark – the problem is they will not likely tell you if they are not confident around money, and you might not find out until it’s too late.

A reluctance to talk about budget early.
Some architects are afraid that discussing budget too soon could scare a client off, so they focus on giving ‘free ideas’ and the exciting vision instead only for you later to discover that what’s been designed is financially not possible.

A lack of accountability.
This is where many homeowners feel let down. Ask any architect – are they accountable for “designing to budget?” and watch them squirm. When tenders come back tens or hundreds of thousands over budget, it’s often the client and not the architect who’s left to pick up the pieces. In many cases, homeowners are asked to pay extra fees to redesign or “value engineer” a plan they couldn’t afford in the first place.

2. The Cost Confidence Mirage

Chances are you’ve watched Grand Designs and so you’ll recognise the moment when Kevin McCloud asks how much the build has cost. The answer is usually a figure that’s shockingly over budget. It makes for great television, but for homeowners, it’s a very real, expensive and traumatic, wake-up call.

This pattern happens often. A client starts with a dream, a clear vision, and maybe even a Pinterest board. An architect brings those ideas to life in detailed drawings. Planning permission is secured and excitement builds.

Then comes the pricing stage.

Builders are asked to quote, and suddenly the numbers seem disconnected from expectations. The scope has crept, including more works than originally expected. Material costs have increased. Labour is tight. The design that was once within reach now seems financially unviable. (watch my video for more on this here)

The result is often a painful sequence of events:

• The handbrakes are pulled.

• Redesigns and resubmissions

• Compromises and stripped-back ambitions

• And limited contingency for unexpected changes during construction

This isn’t necessarily due to incompetence but competence is a factor. It’s caused by a lack of project management, by outdated methods, poor sequencing and unfortunately most traditional design-led projects are structured like this: Design first and price later.

But this means you don’t really know what your project costs until you’re already far into the process.

3. So how can this be fixed?

The answer is simple, even if it goes against the traditional route. You need to bring detailed costing into the design process much earlier. We call this Early Detailed Pricing… (see Our Process here.)

This should not come from an architect who is unqualified in pricing, or a builder who might give an optimistic estimate just to win the job. It needs to come from a team that integrates design with detailed, up-to-date cost analysis.

That means working with a company who can produce tender-grade pricing while your project is still in planning or at a similar early stage, using real construction input and live data from the market so you see where the money is going, what’s driving the cost,  and where value engineering could make a difference. Taking this step early and not after building regulations or once everything’s already locked in means there is still time to shape the design in one go, make informed choices, and align everything with your budget.

4. But why isn’t everyone doing this already?

It’s almost impossible! The Traditional Route means you pick an architect to design, then later,  multiple builders tender to win your job. Who is suitably competent and properly motivated to detail price your project early in the design process?

In reality, most architects and builders still operate in two different spheres, rarely collaborating in a way that allows design, cost and buildability to speak to one another from the beginning.

Architects often don’t have access to a builder who is both motivated and available to provide detailed input at the early stages, and even when a builder does provide a quote, it’s often based on fragmented and incomplete information, barely digested. As the design evolves, that figure quickly becomes outdated or invalid.

A compromised renovation can end up costing just as much, both financially and emotionally, as a home you truly love. That’s why it’s essential to make thoughtful, informed decisions from the very beginning, with clear visibility over costs at every stage. An early detailed pricing approach is the most effective way to give homeowners genuine confidence. It helps avoid hidden costs, prevent last-minute compromises, and ensures the project stays aligned with your budget and your vision.
