Do I need an architect for my extension?

You do not legally need an architect for most home extensions, but one can add significant value — better design, smoother planning applications, and avoiding costly mistakes. For listed buildings or complex projects, professional design advice is strongly recommended.

What is the difference between an architect and an architectural designer?

An architect is ARB-registered and holds a protected title requiring 7+ years of training. An architectural designer may be equally skilled but without ARB registration. Both can produce drawings and submit planning applications.

When do I need a structural engineer?

You need a structural engineer whenever you are removing or altering load-bearing walls, adding a loft conversion, building an extension, or addressing subsidence. Building control will require structural calculations for these works.

What is a party wall agreement?

A party wall agreement is required under the Party Wall etc. Act 1996 when you carry out certain work near or on a shared wall with a neighbour. A party wall surveyor manages the notice process and resolves any disputes.
