DIY vs Hiring a Professional Architect

Important: Certain architect work is legally required to be carried out by a professional holding ARB (Architects Registration Board) registered — legally required to use the title 'Architect' certification. Undertaking regulated work without the correct qualifications can invalidate your home insurance, breach building regulations, and — in serious cases — create significant safety risks. Never attempt to bypass these legal requirements to save money.

You should always hire a professional architect for work that:

For small, cosmetic or inherently low-risk tasks — such as minor adjustments, surface painting, or straightforward component replacements — a competent DIYer may proceed safely. When in doubt, the cost of a professional is almost always justified against the potential expense of rework or repairs.

Frequently Asked Questions

How much does an architect charge in the UK?

Architects in the UK typically charge 7–15% of the total build cost for a full service (from initial design to construction oversight), or £100–£200 per hour for individual services. For a £150,000 extension, full architectural fees might be £10,000–£22,500. Some architects offer fixed-fee packages for planning drawings only, from £1,500–£5,000 for a typical residential project.

Do I need an architect or can I use a architectural designer?

Only individuals registered with the Architects Registration Board (ARB) can legally use the title 'Architect' in the UK. However, many structural and architectural drawing services can be carried out competently by ARB-registered architectural technologists, building designers, or qualified structural engineers for simpler projects such as extensions or loft conversions. For complex or sensitive projects, a fully ARB-registered architect is strongly recommended.

What does an architect do for a house extension?

For a house extension, an architect will typically: conduct a site survey and feasibility study; develop concept designs and presentation drawings; prepare planning application drawings and submit to the local planning authority; develop detailed construction drawings for Building Regulations approval and builder tender; specify materials and finishes; and administer the construction contract to ensure the builder meets the agreed specification.

How long does the architectural planning stage take?

For a residential extension or conversion, the full journey from initial architect brief to planning permission decision typically takes 4–6 months. This includes: initial survey and design (4–8 weeks); design development and client approval (2–4 weeks); planning application preparation and submission (2–4 weeks); and planning authority determination period (8–13 weeks). Building Regulations drawings and approval add a further 4–8 weeks.

How do I find a reliable architect for a home project?

You can search for ARB-registered architects at arb.org.uk and RIBA-chartered practices at architecture.com. Always meet at least two or three architects before appointing, review their portfolio for similar projects, and request a detailed written fee proposal itemising each stage. Personal recommendations from people who have recently completed similar projects are particularly valuable. Confirm their professional indemnity insurance is current.
