Proteus facades transforms historic London building

Visually striking rainscreen cladding panels from Proteus Facades have helped to transform a building on London’s historic Hoxton Square, which is undergoing major refurbishment as part of a high-profile expansion project.  

Aviva, a British multinational insurance company and pensions provider, identified Hoxton Square as the ideal location to create a campus of offices and relocate its Digital Garage; a dedicated space where technical specialists, creative designers and business leaders collaborate to develop new ideas and services. As part of the development, known as Project Drum, Aviva purchased 28-30 Hoxton Square along with other buildings in the area. 

28-30 Hoxton Square required a substantial level of refurbishment, which created the opportunity to extend the property to increase capacity and improve accessibility and the layout between two front facing blocks. Architects TTSP redesigned the three-storey structure, with an entirely new floor added to the front and rear elevations as well as the demolition of a single storey centre, which was rebuilt to four storeys. 

A major part of the brief given to TTSP was to ensure that historic structural elements of the building were retained and left exposed whilst all new visible external elements were over-clad to harmonise with the original features. Working closely with TTSP, Proteus Facades provided support with the design of the rainscreen cladding system to ensure this challenge was met. 

Proteus HR TECU Patina Madrid panels, installed by Openwood Facades Ltd, were chosen for the double height storey which sits atop of the central part of the building, with architectural fins to the south elevations and window frames designed to match. The patterned copper finish of the Proteus material perfectly complements the colours and textures of the surrounding buildings, whilst staying in keeping with the heritage of the original site that dates to the 1700s.

Proteus HR VM Zinc Quartz rainscreen cladding was also specified for the roof level of 28- 30 Hoxton Square, which provides a long, maintenance-free life and offers adaptability to various design styles ranging from traditional to modern. Proteus HR was specified for both the TECU Patina Madrid and VM Zinc Quartz materials at Hoxton because it is a lightweight, strong and versatile cladding panel that creates an optically flat aesthetic that is highly suited for building facades. The integrated modular rainscreen system features an aluminium honeycomb core, structurally bonded between two thin gauges of lightweight metal skin to create an optically flat panel that is available in aluminium, steel, zinc, stainless steel, copper alloys and other materials.

To mirror the design of the external façade, Proteus HR TECU Patina Madrid panels were also specified for use on a double-width lift lobby, which acts as a bright and bold mid-section connecting various internal departments, including a state-of-the-art AV centre. 

In addition, Proteus Facades supplied mesh screens fixed to windows along the rear elevation in a Polyester Powder Coated (PPC) finish, which remains a popular choice with architects because of its long-term performance and cost benefits. 

All factors which resulted in the development being named as a finalist for the Mixology19 Awards in the Medium Commercial Interiors of the Year category.

Proteus Facades offers one of the widest ranges of TECU copper and copper alloys in the UK. This includes TECU Brass, TECU Copper, TECU Bronze, TECU Patina Madrid, TECU Gold, TECU Zinn, a tin-plated copper that weathers from silver to subtle grey tones, along with many others. 

All the materials are available pre-patinated, which bypasses the gradual weathering process, so that the cladding panels take on the beautiful earth tones from the day the facade is installed. Proteus Facades also offers a range of other surface treatments that avoid, delay or accelerate the weathering process. 

Originally built in the 1700’s as an upmarket residential development, by the late 20th century Hoxton Square became the place to be for artists, musicians, photographers and other creatives in London, which attracted crowds from across the city. As digital technologies have prevailed however the area is now home to a number of leading digital and tech led businesses like Aviva.
