1 South Place
This development, also known as the Helicon, features a Marks & Spencer store on the lower three floors, together with a bank and speculative offices on the upper levels. At first glance there are some similarities with the work of Rogers, Stirk, Harbour & Partners, around the office fašades and especially in the way the cores are handled. Probably the most striking element of the scheme is the office entrance. This is a south facing curved glass wall, the full height of the building, secured in place by an impressive combination of vertical steel lattice columns and cable braces. The fašades to the offices feature triple-glazed curtain walling, with an accessible 900mm gap between the outer and middle panes. This gap contains adjustable horizontal blinds and can also be opened and closed at the top and bottom, as the weather dictates, to help temper the internal environment. An internal atrium, starting at third floor level, helps to provide natural light to the offices.
