Frequently asked questions
Do I need an architect for a home extension in London?
There is no general legal requirement to appoint an architect for a house extension. Architectural services can be provided by others, but the protected title “architect” may only be used in business or practice by someone entitled to use it. Archi Project provides architectural design services and no architect is appointed as part of the standard service.
Can you prepare planning drawings for a project in London?
Yes, for suitable small residential extensions and loft conversions where the required existing information is available. The exact requirements depend on the property and relevant local planning authority.
Can you prepare Building Regulations plans too?
Yes. A combined Planning + Building Regulations package is available, subject to the written scope and information supplied.
Do you visit the property?
The standard service is 100% online and does not include a measured survey or site visit.
