The first UK application of Technal’s new FXi balcony doors has been completed. Allan Murray Architects’ Coalhill development is a significant landmark in the regeneration of the historic docks at Leith in Scotland.

A joint venture by BUREDI – the Burrell Company and EDI Group, this waterfront scheme takes its inspiration from its nautical setting. It has a light, spacious feel with a modernist white rendered exterior and is extensively glazed in Technal’s black framed aluminium curtain walling, door and window systems.

The seven-storey development comprises two distinct blocks, one oval and one rectangular, each containing 15 apartments, with restaurant and retail units on the ground floor and open plan office suites on the first floor. The oval block has commanding panoramic views, which were maximised with the use of Technal’s facetted MC curtain wall to follow the cylindrical lines of the building, and the new FXi doors to the balconies.

The stylish curved profiles of the contemporary and highly engineered FXi52 doors compliment the design of the building, whilst an efficient flush polyamide thermal bridge provides excellent thermal performance.

The MC Trame curtain wall, which features distinctive horizontal lines, adds interest to the glazing that encloses the commercial units, and contrasts with the MC grid curtain walling used for the apartments. Opening lights were provided by top hung concealed vents to naturally ventilate the offices and retail units, and tilt/turn windows for ease of cleaning on the residential floors above.

According to the architects, aluminium was selected for the glazing for its low maintenance qualities, its long-term durability in a marine situation and its finished appearance. The systems were double glazed in clear low E glass and fabricated and installed by St Gobain Solaglas.
