Do I need an architect to apply for planning permission?

Anyone can submit a planning application, including you as the homeowner. Councils care about the quality and accuracy of what's submitted — existing and proposed floor plans and elevations at recognised scales, a site location plan, and the right forms and fee — not the letters after the designer's name.

For a straightforward extension, an architectural technologist or a drawings-focused service often costs significantly less than a full architect service and produces exactly what the council needs. Many homeowners use an architect only for design-led projects where the outcome depends on creative problem-solving.

Where professional input genuinely pays is on constrained sites: conservation areas, listed buildings, awkward plots, or streets where the council has refused similar schemes. There, design judgement and knowledge of local policy directly move your approval odds.

Whoever draws your plans, brief them with evidence. Knowing what the council has approved and refused near you — sizes, materials, design details — turns the drawing stage from guesswork into a targeted design that fits local precedent.

One caution: don't pay for detailed drawings before you understand your property's constraints. Discovering an Article 4 direction or a conservation designation after the drawings are done is one of the most common ways homeowners waste money.
