Castle Construction was started as a brickwork partnership in the 1960's by Reg Botham developing small projects including extensions and remedial works. His son Steve Botham joined the company in 1983 as an apprentice. The turnover and employees steadily increased over the following years which resulted in the company becoming limited in January 2002, with Reg and Steve as the two Directors. Neil Botham became a Director in April 2009.
