Member Focus – Cass Allen


We are a specialist Acoustics Consultancy focused on the development and construction industries. We work on some of the most prestigious projects in the UK alongside the world’s finest architects and construction professionals.


We aim to be at the forefront of consultancy firms, with a strong commitment to our clients and their projects. We are a medium-sized independent company, large enough to handle the most complex of projects, but small enough to respond flexibly to client needs and allow our clients the reassurance of knowing the consultants working on their projects.


Our consultants are all qualified to at least first degree level in acoustics and senior staff are Chartered Engineers. Our consultants back up technical knowledge with practical experience and a pragmatic outlook on solving real-world acoustic problems. They are supported by state of the art instrumentation and computer modelling facilities.
