About Us


An award-winning multi-disciplinary planning and design practice based in Liverpool. We offer an integrated range of services with specialist expertise embracing architecture, planning, landscape architecture, masterplanning, and conservation.

We take an intensely client-focused approach to our work and have been very successful at creating and releasing value for our clients. Each project, regardless of scale, is led by a partner who remains the key client contact until completion.

Since 1983 we have applied our specialist and multi-disciplinary skills to over 1400 completed projects across the UK, from the very large to the very small, across a wide range of sectors and for both private and public sector clients.

Recurring themes in our work are sustainable development, client and community engagement, responding to the natural environment  and the integration of contemporary design with heritage assets.

At Cass Associates we strive to create communities, environments and buildings that enhance people’s lives and provide lasting value for our clients.

We run most standard 2D and 3D design and graphics software packages, including AutoCAD and the latest Revit Building Information Modelling (BIM) design suite.

View Capability Statement


Sustainability is central to our thinking and our practice.

Sustainability is about having confidence in the future and to be successful requires joined up thinking that sometimes cuts across traditional professional and technical boundaries. Our projects provide clear evidence of how this can be achieved. We practice what we preach and have created our Sustainability Policy and Carbon Report as a working document to audit our own environmental impact on an annual basis.
