Multi-national law firm CMS commissioned MCM to design the studio-style work space within their 140,000sq. ft. new headquarters at Cannon Place in the City of London, whilst KKS designed the state of the art client suite. One of the main challenges on the project was balancing acoustic performance against cost. 

Cannon Place, Cannon Street, London

MCM Architecture Ltd / KKS Strategy LLP


Optima created meeting rooms and quiet rooms/telephone booths around the core of the floor plates, in close proximity to the open plan working environment. Noise break-out was a therefore a key consideration and the glass partitions that were specified had to perform effectively and work within the budget.

With acoustic and cost issues in mind, Optima’s 117 plus system was selected in order to work within the budget and to achieve a good level of acoustic performance. Optima 117 plus is an elegant single glazed system with minimal framework and discreet glass to glass joints. It can accommodate a range of glass thicknesses, in order to achieve the right balance between cost and acoustic performance.

However, on the client floors, a double-glazed solution was possible and hence acoustic performance was improved significantly through the use of Optima’s Revolution system.  Revolution 100 is a beautifully designed mullion-free system with minimal vertical dry joints between the glass panels. It can be single or double glazed to suit the acoustic specification.

The end result is a stunning, light and contemporary space with clean lines and sophisticated colours.



“Optima provided excellent pre-contract support, assisting with cost and specification advice. The site team was equally pro-active and carried out the installation to a very high standard. The overall experience was positive. A great quality product and good attention to detail. Specification and sales advice was clear and unambiguous and detailing and interface issues were swiftly resolved on site.”
