optima as Architects

In a move that consolidated over 600 staff from three different London offices into a new London headquarters building, prestigious international law firm Pinsent Masons sought to become part of a working environment that maximised space and enabled staff to work together efficiently. It was also important that the office interior was in keeping with the high quality and contemporary design of the building at 30 Crown Place, near Liverpool Street. Optima’s 117 single glazed system and high performing Revolution 97 mullion-free double glazed partitioning proved to offer an ideal solution.

Interior design and architecture practice MCM Architecture was presented with a blank canvas for this modern and impressive new 16 storey building, of which Pinsent Masons were to occupy 160,000 sq ft. The design scheme reflected an architectural approach of simple, stylish design with clean, uncluttered aesthetics.

Due to the confidential nature of the business, privacy within working areas and meeting rooms was of paramount importance. Having previously specified Optima partitions, MCM’s designers were familiar with the acoustic performance, design aesthetics and seamless integration that they offered. Working with main contractor ISG, MCM selected Optima’s Revolution 97 double glazed partitioning system, along with 117 single glazing.

On the client meeting room floors, Revolution 97 mullion free double glazing was installed, with flush bonded doubled glazed doors in Microflush frames. Ingeniously designed, they feature minimal ironmongery to maintain an elegant and sleek look. The virtually invisible patented NebulaTM dry joints used on the adjacent Revolution screens perfectly complemented the doors. The Revolution double glazed screens have been designed to achieve market-leading acoustics of Rw48dB.

In certain areas on the client meeting room floors, curved Kinetic sliding doors integrated into drywall pockets made a bold design statement. Used to maximise available floor space by negating the need for a swinging door, the Kinetic sliding door consists of a 12mm toughened glass leaf acting on carriages within a robust head track, thus providing seamless integration with a 40mm head channel. The vertical edges of the door are sealed in the closed position to reduce sound leakage.

In addition to the Kinetic sliding doors, Optima installed automatic sliding glass doors to form the entrances to numerous floors throughout the building, along with the separation between the dining area and roof terrace on Level 7.

For the working floors, Optima’s 117 single glazed system was chosen to create meeting and quiet rooms. Acoustic laminated glass was used within the screens to achieve a high acoustic rating of Rw37dB, whilst single glazed doors in Microflush aluminium frames provided a minimal design solution whilst still maintaining a good level of acoustic performance.

To allow for any movements in the building, both Optima 117 and Revolution 97 feature an innovative extruded aluminium deflection head, developed by Optima. This allows a tolerance of +/-25mm, ensuring the glazed panels do not suffer from stress in the event of any movement.

With the installation now complete, Optima’s partitioning systems are helping to create a stylish and flexible working environment for the law firm and its staff, within an exciting new headquarters building that forms a striking City landmark.
