On World Heritage Site
May 2017

Architectural aluminium glazing systems by KAWNEER were specified for a landmark office building in the Edinburgh New Town Conservation Area.

Comprehensive Design Architects in conjunction with Hoskins Architects specified three types of Kawneer curtain walling and two types of doors for the £42 million redevelopment of 3 to 8 St Andrew Square on a prominent corner of the sensitive World Heritage Site.

The Kawneer AA110 capped and Structurally Silicone Glazed curtain walling with a 65mm sightline and a bespoke 80mm wide system, complemented by series 190 heavy-duty and 350 severe-duty commercial entrance doors, have been used on the offices on the second to sixth floors of number 6 and on some elements of the eight retail/restaurant units on the ground, first and basement floors of numbers 3 to 8.

The development comprises 112,000ft2 of Category A office space, now let in its entirety to Standard Life Investments, arranged around a full-height atrium, with roof terraces at the fourth and sixth floors, ground floor reception and double-height entrance on St Andrew Square, parking/bike storage at basement level and welfare facilities at lower ground floor.

CDA project director Gareth Thompson said: “The project required different types of curtain walling, capped and SSG, not to mention the bespoke fin caps. The adaptability of Kawneer’s systems played a critical part in achieving the design and successfully resolving the complexities of the different types of curtain walling.”
