Measured surveyors across Devon & South West
Founded by Simon Crowe, combining surveying experience with modern technology.

Quadrant was founded by Simon Crowe, a trained architectural technician with a background in the construction industry.
His understanding of architecture and building design has helped shape our approach to producing clear, detailed and practical survey drawings.
Today, we combine extensive surveying experience with modern 3D laser scanning, drone and photogrammetric technology to provide high-quality survey information for architects, designers and property professionals.
