Quadrant 4
This 1930s Art Deco Hotel building off Piccadilly Circus, has been transformed into 48 luxury apartments by The Crown Estate. The scheme saw the remodelling of the top floors, as well as the addition of a new residential entrance and reception, and striking new retail frontages to upgrade the public realm.

Employed directly by The Crown Estate, we were tasked with the detailed design, manufacture and installation of the façade and internal atrium glazing. Working closely with the construction managers and client team, the challenging design required a competent specialist.
The scheme posed many site constraints particularly the retained structure, which required skilful management and creative thinking, to enable the clients vision to be realised.
The existing street facing façades were retained and renovated with all existing windows replaced. Due to planning restrictions and the historic façade, a slimline steel system was used for these areas which required considerable adaption to meet the intent at terrace levels for the incorporation of large doorsets without compromising performance. Extensive surveying and condition reports were required to ensure the incorporation of new elements into the existing structure were seamless.
With the retention of the street façades, but extensive re-modelling behind this, the rear elevations were more contemporary and an aluminium sliding door system was used for the glazed aspects. A concrete frame with lightweight steel framing as the slab infills, forms the openings for the glazing which was then framed with terracotta once installed.
Within the central lightwell, fire-rated glazed modules were installed into steel framing, but this time framed with timber cladding. Due to the timber cladding, the fire-rated line runs behind this maintaining the integrity of the system.
Quadrant 4 is highly distinctive in design and was engineered to a level of quality that has become a hallmark of The Crown Estate’s development.
