London sites rarely give you much room. Plant space is limited, ductwork has to be routed through light-wells and existing structures, and councils set strict noise limits. We have done it before: at Rosa's Soho our ductwork rose four storeys through an external light-well, with plant noise engineered 10dB(A) below the background level Westminster Council required.
Every canopy is fabricated to order at our own works, then installed by our own engineers, so one contractor stays accountable from survey to commissioning, whether you are in the West End, the City or the outer boroughs.


Twin extraction canopies, a Medem gas interlock and ductwork threaded four storeys through an external light-well, engineered 10dB(A) below background noise for Westminster Council.
