I believed all the usual things about hiring an architect, and most of them turned out to be wrong. Those wrong assumptions nearly led me to the wrong firm and a far worse project.
Once I understood how the better practices actually work, the myths fell apart one by one. The experienced architects in london I eventually chose broke nearly every assumption I had walked in with.
Here are the myths that almost caught me out, and what the truth turned out to be.
The Cheapest Quote Saves You Money
This was my biggest mistake in the making. I assumed the lowest quote meant the best value.
It doesn’t. A cheap quote usually covers planning drawings and nothing else. No structural coordination, no site visits, no support through the build. You pay for all of that later, separately, often at a worse price. The firm worth choosing isn’t the cheapest. It is the one whose price includes the whole journey. I learned to compare what was actually included, not just the number at the bottom.
A single storey extension cost calculator can help you understand realistic price ranges before you start comparing quotes.
All Firms Offer the Same Thing
I thought architecture firms were basically interchangeable. Pick any competent one and youre fine.
Far from it. Most outsource their structural engineering to a separate company. A small number, around one in ten, keep it in-house.
That difference is huge. When the structural engineer sits in the same office as the designers, the design and the structure agree from the start. The firm I chose worked this way, and it removed a whole category of problems before they could happen.
An Architect Just Draws Plans
The myth that nearly made me skip an architect entirely. I thought they drew pretty pictures and that was the end of it.
The drawing is the smallest part. The real work is feasibility studies, matching the right design to your house, winning planning permission, coordinating structure, and managing the build.
One firm I researched had completed over 500 projects and secured a vast number of planning approvals, including applications that two other architects had already had refused. That is not a drawing service. That is hard won expertise.
Planning Permission Is a Formality
I genuinely thought you submitted plans and the council rubber stamped them. That naivety could have cost me months.
Planning is where projects live or die. A council decision takes six to eight weeks, and a refusal sends you back to the start. The skill is designing something that passes the first time.
A real client story stuck with me. One homeowner in a flood risk and conservation area, the hardest kind of case, got approval in seven weeks because the firm knew exactly how to present it. That is what planning expertise actually looks like.
A Good Result Is Just Luck
I assumed a smooth, valuable project was mostly down to chance. It isn’t. It comes from the team and the approach.
The proof is in measurable results. One firm had added around thirty percent to a home on Tadorne Road, twenty percent to another on Bradstock Road, and twenty five percent on Taunton Road. Real addresses, real numbers.
That consistency isn’t luck. It comes from a design and build approach where one team carries the project from feasibility to the finished room, with nothing falling through the gaps.
You Cannot Picture It Until It Is Built
Another thing I wrongly believed. I assumed I would just have to trust the flat drawings and hope the finished space felt right.
Not true with a good firm. They show you the design in 3D, sometimes in VR, so you can walk through the space before a single brick is laid.
That meant I caught problems on screen, where fixing them cost nothing. A window I wanted turned out to face a wall. We changed it for free, long before the build, instead of discovering it expensively on site.
A Local Firm Cannot Handle a Complex Job
I had assumed you needed a big national name for anything ambitious. Wrong again.
The practice I chose was a focused London team, based in Battersea, with in-house planning, design, structural engineering, and project management all under one roof.
That structure handled my project better than a sprawling firm would have. A well built local team, with the right specialists, beats a big name that passes you around. Size isn’t the same as capability.
What Believing the Myths Would Have Cost
Had I trusted those myths, I would have hired the cheapest firm, assumed they were all the same, expected only drawings, treated planning casually, hoped for luck, and chased a big name.
Instead I checked the credentials, found a firm with in-house engineering, valued the full service, took planning seriously, judged on real results, and trusted a focused local team.
Six to eight months from first meeting to a finished home, and avoiding those myths was worth far more than any clever design. The things everyone believes about architects in London are often the very things that cost you. Question them, and you choose far better than I almost did.
