About · Our team

Building surveyors, quantity surveyors and project managers who have worked on both sides of the contract.

A small team by design. Every client deals directly with the people doing the work.

Ryan Delany
Ryan Delany MCIOBSenior Building Surveyor

Ryan is a Chartered Member of the CIOB with more than twenty years in construction, beginning on the tools as a mason before moving into project management of residential and commercial works across London. That hands-on grounding shapes his surveying: specifications that are buildable and advice that holds up on site. He also brings measured survey expertise, including LiDAR point-cloud capture of period and complex buildings.
