Architect vs Designer: The Real Differences

Updated: Jun 14

Choosing between an architect and a designer isn’t just semantics – it can make or break your Dorset project.

In the UK, “architect” is a protected title. It means someone has completed years of formal education, passed rigorous exams, is insured, and is registered with the

Architects Registration Board (ARB). By contrast, “designer” is unregulated. Anyone can use the term, regardless of qualifications or experience.

So while both may draw plans — only one is legally accountable, professionally insured, and trained to see the project through with technical precision and authority.

Architect vs Designer

Here’s what sets an architect apart from a designer in practical terms:

✅ Qualification & Legitimacy

Architects complete a minimum of 7 years of training and must pass professional exams.
They are listed on the ARB register, which you can check anytime.
Designers may or may not have formal training — there is no legal standard for the title.

✅ Planning & Regulations

Architects are trained to navigate complex planning rules, especially in local councils like Dorset.
They understand building regulations and can design for compliance from day one.
Designers may lack in-depth knowledge of policy, risking delays or rejections.

✅ Risk & Accountability

Architects are insured and bound by a professional code of conduct.
Designers are not required to hold insurance — meaning if something goes wrong, you could be unprotected.

✅ End-to-End Support

Architects coordinate consultants, engineers, and builders.
They manage the full design-to-construction process with professionalism.
Designers typically provide drawings but may not support you beyond that.

So Why Rosenkelly?

Rosenkelly Architectural Design is currently the only ARB-registered architect based in the DT4 postcode. And we’re proud of that.

Now, that doesn’t mean there aren’t talented designers or other consultants in the area — some may be great at what they do. But when it comes to formal architectural qualifications, legal accountability, and insured expertise? Rosenkelly stands alone in this postcode.

So yes… technically, that makes us:

✅ The best architect in DT4
✅ The worst architect in DT4
✅ Because we’re the only ARB architect based here

(You can verify that yourself with a quick search on the ARB register.)

And we don’t just serve Weymouth — we work throughout Bridport, Portland, and the Dorset region.

How We Work

Here’s how your journey begins with Rosenkelly:

Desktop Feasibility StudyBefore we even meet, we carry out a thorough desktop review of your site — using policy maps, planning history, and local constraints to ensure your project is viable and realistic.
One-Hour Property Consultation (Small Fee Applies)We then meet at your property for a full hour with a fully qualified architect. This isn’t a sales pitch — it’s a deep, tailored conversation about your goals, constraints, and opportunities.There is a small upfront fee, but clients consistently say they get far more than they pay for. In truth, the fee isn’t just about time — it’s a way to show that you’re committed and ready to take your project seriously. We’re investing in you, and this shows you’re invested too.
Formal Letter of AppointmentIf you're happy to proceed, we’ll issue a clear, professional letter of appointment — your personalised roadmap through the design, planning, and building journey. No hidden steps. No vague handshakes. Just clarity and confidence from day one.

We call this the starting line — because smart projects don’t begin with guesswork, they begin with good information and solid advice.

FAQs

Do I need an architect for a loft conversion or extension?Not legally. But if your project requires planning or Building Regulations sign-off, a qualified architect gives you the best chance of success — without costly mistakes.

Can designers take you through the whole process?Some can. But many don’t — and not all are insured or up to date on regulations. Before committing, always check their credentials and whether they’re covered to advise you.

Is Rosenkelly more expensive than a designer?We might cost more upfront, yes. But we save you money long term by doing it right the first time. Our clients often say the insight and clarity we provide is worth every penny.
