Compare architect firms in Cardiff for extensions, renovations, new homes and other building projects.
Search is free. Choose the architects you want to approach; participation and availability are confirmed before an introduction. A listing is not a promise that a firm can take on your project.
Prepare your Cardiff project brief
Confirm the Welsh planning route and relevant local requirements for your exact property. Do not assume that guidance written for England applies unchanged.
Questions for your shortlist
Compare how each architect will coordinate feasibility, application work and detailed design under the applicable Welsh requirements.
- What comparable work did your proposed project lead deliver?
- Which surveys, drawings and applications are included in the fee?
- How will you test the design against our budget?
- What technical information and construction support are included?
Planning and technical approvals in Wales
Check requirements with the authority responsible for your site. Planning and building-control processes are separate; the services and approvals needed depend on the proposed work.
Welsh planning application guidance
Compare a clear written scope
Check the named professional, relevant project experience, services, exclusions, revisions and fee basis. Confirm registration and insurance before appointment. RIBA membership and ARB registration are different checks; a directory listing does not establish both.

Does a local listing mean the firm is available?
No. Location searches identify listed offices; they do not guarantee project coverage, availability or participation. Check the firm’s relevant experience and confirm the appointment before proceeding.
