Cass Allen is currently working alongside Essential Living on the regeneration of the former Perfume Factory site in North Acton from RIBA Stage 3 to project completion. The proposals include the construction of 3 towers to provide approximately 400 new homes as well as a number of large retail spaces.

The site is acoustically challenging as it is bounded by a busy road, a railway line and an existing industrial estate. Through a combination of site noise surveys, detailed 3D modelling, and calculations, Cass Allen has been able to demonstrate that appropriate living environments can be provided for future occupants.
