Steel frame structure with layered cantilevers at ground and first floor levels. The ground floor plan overhangs the adjacent river using storey deep steel trusses along the side elevations, and these are in turn prevented from overturning by the first floor cantilever truss which runs on a perpendicular axis. The structural principle is similar to the renown Goulding House in County Wicklow by Scott Tallon Walker, however the simplicity of the diagonal bracing in that example could not be achieved as uninterrupted views through all windows required us to design hybrid Vierendeel trusses. To minimise the steel sections sizes the tips of the cantilevers have been pre-set upwards to offset dead load deflection.
