Office Transformation Delivers New Twist on Traditional Stone Façade Originally constructed in the 1920s, Axtell House is an office building that boasts both original Art Deco features and a location a stone’s throw from Regent Street.

A

refurbishment delivered by RED Construction has added three new storeys, with Shackerley’s SureClad® Engineered Stone ventilated façade system, specified in a creamy beige colourway to reference the Portland Stone of the original façades. The panels were sandblasted to create a textured finish and some were also detailed using computer numerical control (CNC) engraving, creating vertical linear fluting that replicates classical stone detailing. The design concept for the additional storeys was to integrate stone and metalwork into a contemporary mansard roof. The weight and strength of the engineered stone panels were key considerations as it was vital to minimise structural loading to avoid any need for strengthening the existing structure. Fire tested and certified A2/S1 in line with BS EN 13501-1, the SureClad Engineered Stone system is versatile and so robust that panels of just 2cm and 3cm thick could be used, creating the impression of natural stone at a fraction of the weight. Specialist contractor, Dmitro Facades worked closely with Shackerley to ensure production schedules were aligned to the detailed façade plans and installation programme.

“Shackerley helped us to ensure that the whole installation ran like clockwork and the results are stunning” - Mustafa Kurtumerov from Dmitro Facades

Mustafa Kurtumerov from Dmitro Facades explains: “The design of the new elevations was quite complex with curtain walling and anodised metallic cladding sitting alongside Shackerley’s SureClad® Engineered Stone panels, which meant there were a lot of interfaces between the different materials. “It was essential that fully-fabricated panels were available on site ready to install on a just-in-time basis, because storage and access were limited. Shackerley helped us to ensure that the whole installation ran like clockwork and the results are stunning.” All façade elements were custommanufactured at Shackerley’s ISO9001accredited production plant in Lancashire. This included CNC-engraved 30mm thick engineered stone panels. Each groove was precision cut to create a channel 35mm wide and 15mm deep, creating total uniformity for the decorative finish. A number of complex pre-assembled units were also factoryfabricated by Shackerley to enable faster and easier installation.

In total, more than 100 different types of panel and detail were specified, including

panels of varying sizes, with the largest panels used on this scheme measuring 1732mm x 925mm. The system was installed using Shackerley’s SureClad® ‘Hang On’ system, which allows the panels to be lifted into position on horizontal rails and provides full support while they are being levelled; a feature of the specially-designed brackets that Shackerley fixed to the reverse side of each SureClad® Engineered Stone panel with stainless steel undercut anchors. Adjustment bolts in these brackets make manoeuvring each panel into the correct position on the façade quick and simple. Mustafa continues: “Although the cladding installation covered a relatively small area, the complexity of the design, the mansardstyle windows and the interface between different materials made this a potentially challenging installation. However, the close working relationship and technical support we had with Shackerley throughout helped the job to run smoothly.”
