Project in Focus: Hackney Road

Posted on Monday, January 15th, 2018

95 Hackney Road is located in the bustling and stylish area of Shoreditch, East London. Stretching over five upper floors plus a basement, this development includes both residential and commercial units. Each area of this development has been meticulously planned and designed with precision, providing high specification throughout. Having previously worked on a successful project with Stephen Marshall Architects using the CGL Traypanel System, they approached us again to give this building a similar look with our perforated cladding and the stunning façade certainly looks right at home at this exclusive address.
