castle-davis is a design focused construction consultancy, expert in bespoke project and cost management.

The company was formed in 2003 by Andrew Dufty and has gained extensive experience working collaboratively with in-house and external project and cost managers on projects with the world’s leading architects, engineers and designers on development, masterplan, new build, extension and refurbishment.

Complex projects can involve many people; their contribution and responsibility are interwoven and interdependent. castle-davis’s responsibility is to reduce risk, optimize programme and agree costs, while striving for excellence in coordinated design, procurement and construction, creating value for discerning clients.

Construction is inherently risky, we interrogate projects from an early stage to ensure a client’s requirements are met with good design, but find it critical for architects and engineers to appreciate the available budget and timescale and we aim to work within those constraints without diluting enthusiasm or creativity.
