The project involved the creation of a second cinema and bar to accommodate the growing community program and help drive revenue for The Lexi's ecological charity efforts. The extension was designed with a sensitive approach to exercise consideration to the neighbouring adjacent homes. 

RISE reduced the visual bulk by echoing the neighbouring parapet roofs and creating a solid superstructure of in situ cast concrete arches, which lean away from neighbouring gardens on a 45º angle. The new extension features a green wildflower roof to replace biodiversity lost at a higher level. 

The Lexi Hub is sealed for airtightness to minimise heat loss and energy usage and features an Air to Air Source Heat Pump and a MVHR system. During construction, a fire caused major smoke damage to the original cinema, Screen One, requiring a complete refit of the existing interiors. RISE salvaged original period details and character, including the parquet flooring, which was restored to the Box Office.
