Dorma Fit For a Former Palace

The Crown Estate’s ambitious £1 billion redevelopment of lower Regent Street has made a significant leap forward with the conversion of the former Regent Palace Hotel into Quadrant 3, a mixed use building which will help transform a prominent part of the West End.

In a scheme that combines the best of modern architecture whilst accentuating London’s built heritage, it was important that any product specified in the landmark building was able to provide both aesthetic design and functionality. DORMA was the natural specification choice with their range of high performance door hardware, automatic doors and glass fittings at such a landmark building.

Located just off Regent Street and Piccadilly Circus, the stunning Quadrant 3 redevelopment will provide 65,000 sq ft of retail and restaurant space beneath 200,000 sq ft of grade A offices. This environmentally intelligent building has
energy saving technology, a BREEAM ‘Excellent’ rating and is one of four quadrant blocks undergoing restoration and redevelopment at the southern end of Regent Street.

In keeping with the exemplary style of this Grade II listed building, architectural ironmongers Scott Beaven Radius Ltd and architect Dixon Jones were able to select door closers and ironmongery that were both aesthetically pleasing and compliant with the latest legislation. Stephen Waistell of Scott Beaven Radius Ltd commented: ‘We were asked by architects Dixon Jones to provide an ironmongery specification for this landmark project and worked closely with them to understand the needs of the building’.

Selecting only DORMA cam-action door closers throughout the building, Scott Beaven Radius Ltd ensured that manual door opening forces would meet the requirements of Approved Document M, ensuring ease of access for all users. For the basement areas, DORMA provided 126 of its uniquely styled TS97 surface mounted cam-action door closer in their compact Contur design along with a number of the proven TS92 cam-action closers which have been installed with the electro-magnetic hold-open feature, designed to secure fire doors in the open position, closing automatically only in the event of a power cut or if the fire alarm is triggered. For the high trafficked areas of the impressive atrium gallery, 14 of the versatile and elegant TS93 cam-action closers were also supplied with the hold-open function.

Offering the illusion of an invisible closer and in tune with the modern and sleek interior space, 130 of the DORMA ITS96 cam-action door closers were specified in the public areas, due to both their low opening forces and hidden design. This concealed cam-action closer is completely integrated within the door leaf and frame.

‘The architect was keen to keep the ironmongery simple and minimal in the public areas and because the ITS96 is a concealed closer, it suited his requirements perfectly,’ added Stephen Waistell of Scott Beaven.

DORMA cam-action closers are CE Marked to BS EN 1154 or BS EN 1155, Certifire Certificated and help ensure doorsets are able to meet the requirements of Approved Document M of the Building Regulations and BS8300.

With performance, durability and aesthetics crucial to the design, the architects also specified HSW-G sliding glass wall system with fittings in a bronze anodised finish to complement the colouring of the building’s art deco lobby area. Installed between the central lobby and cafe, the panels of the HSW-G sliding glass partition are neatly stacked away when the system is open to give unrestricted access and openess.

Six DORMA ED100 low energy swing door operators were also supplied and installed by DORMA’s team of engineers on the basement level and ground level as part of the bike access and egress areas.

Operated by a wall mounted button, the ED100 provides easy and safe access for all. Specially designed to remove the barrier of physical ability, it enables the door to open at precisely controlled speeds and forces assuring safety. Designed as part of the Contur range, the slim-line ED100 has minimal dimensions to suit all environments and interior designs.

The use of DORMA door controls, glass and automatics on such a prestigious and glamorous project as Quadrant 3 will further enhance DORMA’s reputation as the global market leader for high performance, reliable access solutions.
