"Cathedral Architecture transformed our dated bungalow with a stunning rear extension. From the first meeting to the final handover, the team were professional, communicative, and genuinely passionate about getting every detail right. We couldn't be happier."
"We used Cathedral for a full dormer loft conversion. The planning process felt daunting but they guided us through everything clearly and quickly. The finished room is absolutely beautiful — bright, spacious, and exactly what we'd imagined. Highly recommend."
"Our barn conversion was a complex project — listed building, difficult site, challenging planning authority. Cathedral handled it all with skill and patience. The result is a home we are immensely proud of. Exceptional work from start to finish."
