Why use a local architect in Cardiff?
Cardiff's inner suburbs - Roath, Canton, Cathays - are dense Victorian and Edwardian terraces; the outer city is interwar and post-war semis, with large new-build developments at Plasdwr and around the Bay. Welsh building-regulation and planning rules apply. With conservation areas in Pontcanna, Llandaff and the civic centre, a designer who has taken projects through Cardiff Council planning before is worth the conversation.
Every architect we match is ARB-registered where they use the architect title, or a chartered technologist or designer described accurately as such, with professional indemnity insurance, covering CF postcodes. You choose how many quotes to compare - up to 6.
