Mason Clark Associates Ltd

Engineering Excellence Across Yorkshire Since 1990

We are a multi-disciplinary practice dedicated to developing and sustaining the built environment. With established offices in Hull, Leeds, and York, we bring over three decades of expertise to every project. We believe in putting you, the client, first—meeting your individual needs through tailored services that aim to exceed expectations through imaginative, practical solutions.

Our vision is built on technical excellence. Whether we are working on a private residence or a major infrastructure project, we ensure senior members of our staff are involved at every stage, providing a personal approach that larger corporate firms often lack.

From Grade I Landmarks to Modern Infrastructure

Our portfolio is as diverse as the Yorkshire landscape itself. We have a proven track record of delivering complex projects on time and within budget. Some of our notable work includes:

• Heritage & Conservation: Protecting the City of York Walls, Leeds Town Hall, and the Hull Maritime Museum.
• Infrastructure: Leading major bridge improvements across Hull and the Hessle Foreshore Tidal Defence Scheme.
• Education & Public Sector: Refurbishments at Franklin College, Grimsby, and various NHS pre-lease condition surveys.
• Industrial & Commercial: Warehouse designs, factory extensions, and retail regenerations like the former M&S on Whitefriargate.

Why Homeowners and Developers Trust Us

We don't just provide drawings; we provide certainty. Our team is comprised of highly qualified professionals encouraged to lead within the Institution of Civil Engineers (ICE), Institution of Structural Engineers (IStructE), and the Royal Institution of Chartered Surveyors (RICS).

Specialists in Conservation & Heritage

We have a deep-rooted passion for preserving history. Our conservation engineering team works on some of the UK's most sensitive sites, including Wentworth Woodhouse and Whitby Abbey. We blend traditional engineering wisdom with modern technology, such as 3D Reality Capture, to provide unparalleled accuracy in condition surveys and structural assessments of historic fabric.

A Sustainable Future

We recognise that the construction industry is responsible for a significant portion of global carbon emissions. Our most vital contribution to a Net Zero future is the advice, planning, and design services we provide to you. We are committed to delivering environmentally sustainable solutions that don't compromise on structural integrity or cost-effectiveness.
