In 2010, as part of the Government Building Schools for the Future scheme, Caistor Grammar School secured funding to build an extension to Lindsey House, to provide renovated music facilities, another ICT facility and a room for food technology, something that is new to the CGS curriculum. The funding was secured only days before the scheme was scrapped by the Educational Secretary Michael Gove. The facilities were completed by the following Christmas, and were officially opened by celebrity chef Rachel Green on 24 May 2011. The food technology facilities were removed in 2018 to provide for an extended and remodelled dining area, stemming from the facilities' lack of use.
