The remodelling and expansion of the Exo Centre bring together a fragmented series of interventions and extensions to unify the existing building, providing space for exhibitions, events and education. In August 2018, Evans McDowall Architects won an invited competition to transform the existing building at the Lincolnshire Agricultural Society’s Showground site. The new Exo Centre was to provide an energy-efficient, cost-effective and robust commercial space that is aesthetically sympathetic to both the showground site and the Lincolnshire Agricultural Society’s heritage and core values. The general appearance of the existing building was dated and in need of modernisation. The building had two distinctive elements; the linear steel portal frame and the traditional brick-built pitched roof annexe. The linear portal frame structure that houses the main exhibition hall has been stripped back and reclad with vertical western red cedar cladding. The cladding is broken by a horizontal rail that references the detail of farm sheds that can be found throughout rural Lincolnshire. At the lower level, the cladding is planed vertical tongue and grooved boards, with vertical rough sawn hit and miss boards above. The existing tiled roof to the annexe structure was removed and replaced with a new flat roof and the existing brickwork whitewashed to provide an affordable, low carbon method of brightening the approach to the building. The scale of the openings within the existing brick building was also increased to relate to the agricultural scale and proportion of the openings within the main hall. The environmental design strategy aimed to make use of energy embodied in the existing building and provide extensions that have a building fabric designed to exceed Building Regulation standards. The overall project has embodied sustainable materials and construction methodologies where possible to create a development that has a minimal environmental impact on its immediate and wider context. Through restoration and conversion, the project will secure the life of the building for years to come.
