Everything You Need to Know Before Hiring an Architect for Your Home Project.



Your complete guide to making the right choice for your house build or extension.



If you’re planning a house extension, loft conversion, or even building your own home, one of the first questions you might type into Google is: Do I need an architect?



The answer depends on your project — but in most cases, an architect can save you time, money, and a lot of stress. In this guide, we’ll answer the most common questions UK homeowners ask before hiring an architect.



1. Do I need an architect for my extension?

Not all home improvements legally require a registered architect, but if your project involves:

  • Structural changes

  • Planning permission

  • Maximising space and light

  • Adding long-term value

…then hiring an architect is often the best choice. An architect will spot opportunities to improve layout, function, and style — while helping you avoid costly mistakes.



2. How much does an architect cost in the UK?

Architects in the UK typically charge:

  • 7–14% of the build cost (most common for full service)

  • Fixed fees (for smaller or clearly defined projects)

  • Hourly rates (for advice-based or short consultations)

Tip: A good architect often pays for themselves by helping you avoid design errors, unnecessary work, and planning delays.



3. What’s the process of working with an architect?

Here’s a step-by-step guide for most UK home projects:

  1. Initial consultation – understanding your goals, budget, and style.

  2. Concept design – early sketches, layouts, and mood boards.

  3. Planning application – drawings and documents for your local council.

  4. Building Regulations drawings – technical details for builders and approval.

  5. Tender process – getting accurate quotes from contractors.

  6. Construction stage – optional site visits and project management.



4. Can an architect get planning permission for me?

Yes. Architects regularly handle planning permission for house extensions and new builds.

They know local council rules, design within guidelines, and can increase your chance of approval on the first try.



5. Do I need planning permission for an extension in the UK?

Some extensions fall under permitted development rights — meaning you don’t need to apply.

However, rules vary depending on your property type, size of extension, and location (especially in conservation areas). An architect can confirm this at the start.



6. How long does a house extension take?

For a small extension, allow:

  • 1–2 months – design and planning

  • 2–3 months – council approval

  • 1–2 months – tendering to builders

  • 3–6 months – construction

Bigger projects or those in tricky planning areas can take longer.



7. Architect vs architectural designer — what’s the difference?

  • Architect – ARB-registered, insured, and legally qualified to use the title.

  • Architectural designer – may have design skills but is not regulated in the same way.

If your project is complex, high-value, or needs planning permission, hiring a registered architect offers more protection.



8. Will my architect manage the builders?

Some architects offer contract administration, where they visit site, check quality, and keep the project on track. Others stop after providing drawings. Always check what’s included.



9. How do I choose the right architect in the UK?

Look for:

  • Similar completed projects in their portfolio

  • Clear communication and transparency

  • A good understanding of your budget

  • Positive reviews or recommendations

10. Can an architect design within my budget?

Yes — if you’re upfront about your budget early on. A skilled architect will design smart layouts and recommend cost-effective materials to get the most out of your investment.
