We create bespoke residential architectural solutions tailored to individual client needs. Our expertise covers new home construction, property extensions, and heritage building adaptations. With a focus on functionality and aesthetic appeal, we combine technical precision with creative vision to deliver spaces that enhance daily living while maintaining compliance with planning regulations.
Listed building work
Specialist services for historic properties requiring sensitive modifications. We balance preservation requirements with modern living needs, ensuring structural integrity while introducing contemporary elements. Our experience with 300+ year-old buildings demonstrates our ability to navigate complex planning constraints and deliver successful outcomes for heritage projects.
Planning applications
Comprehensive support for planning permission submissions. We prepare detailed drawings and documentation, liaise with local authorities, and address regulatory requirements. Our established relationships with planning departments help streamline approvals for extensions, conversions, and new developments across South Wales.
Home extensions
Tailored extension solutions that maximise space functionality and property value. We design open-plan living areas, additional bedrooms, and multi-functional spaces while maintaining architectural harmony with existing structures. Our approach ensures seamless integration of modern elements with traditional building styles.

We assess structural viability, design efficient layouts, and manage the conversion process from concept to completion.
