What does an architect do?

An architect turns what you want from a building into drawings that can be approved and built. On a home project that usually means a measured survey, design options, drawings for a planning application or a lawful development certificate, a building regulations package and, if you want it, help choosing a builder and checking the work on site. Some practices cover every stage; others stop once planning is approved. Each guide above explains the rules for that kind of job and what to ask before you appoint anyone.

Do you need planning permission?

Not always. In England many single-storey rear extensions and loft conversions can be built as permitted development, within the limits in Part 1 of Schedule 2 to the General Permitted Development Order 2015. Flats do not have these householder rights, conservation areas narrow them, and an Article 4 direction can remove them. Listed buildings need listed building consent for work that affects their character. Our planning applications guide covers when you need to apply and what the council asks for.

Building regulations are a separate approval

Planning decides whether you may build; building regulations decide how. They cover structure, fire safety, insulation, ventilation and drainage, and you apply either to the council’s building control or to a registered building control approver. Most extensions, loft conversions and structural alterations need approval, and GOV.UK explains how to apply.

When does the Party Wall Act apply?

If the work touches a wall you share with a neighbour, or you dig near their foundations, the Party Wall etc. Act 1996 may require you to serve notice. The government’s explanatory booklet says notice for work to an existing party structure is due at least two months before it starts. An architect can tell you whether it applies; our party wall guide explains the notices.
