Stanfield House Guildingwells

We would like to thank the team at Castle Owen for all of their support in the design, planning and build of our extension to the rear of our home. We were made to feel at ease and enjoyed an inclusive and professional experience at all stages.

With many restrictions in place owing to the relationship of our house with existing properties and being situated within a conservation area, Jon created an innovative, cutting-edge design, which more than fulfilled our brief. We were advised on material choice and assisted in a less than straight forward planning process including the compiling of a heritage report.

As building commenced, there was regular dialogue with our builder and the visits of building control at all stages. We are thrilled with result and can wholeheartedly recommend the services of Castle Owen.


Castle Owen are a vibrant office committed to designing with people at the heart of our projects. We design spaces, places and buildings that combine innovation and skill with a strong social, economic, and environmental agenda. We are an ambitious design led office with a strong knowledge of construction and a professional approach.

Our vision is focused on designing buildings and spaces which improve people’s lives, whilst respecting and enhancing the natural environment around us.

Castle Owen are appointed to the NHS SBS construction consultancy framework under Lot 1 – Architecture and Lot 6 – Principal Designer.

My true memory of the last two years sits more with the human factor, Castle Owen are just easy to work with. They listen, they understand, and they provide the options/solutions, always in a friendly and enthusiastic manner. Just good Architecture.
