The original Denbigh School opened September 1964 where half of Wilton high's students were part of the initial intake for the school, which was located on land at the northern end of Cornwall Grove in Bletchley. In the 1980s, the Local Education Authority resolved to relocate either Denbigh or Lord Grey School to Shenley Church End, a few miles to the north. Eventually Denbigh was chosen to move. In 1991-1992 term years 8 and 9 were located at the new school and other years located at the old one, the school was still in the process of being built at the time. All years moved into the new school in July 1992. When the Shenley site opened in 1991, the site had the following areas completed, Humanities Block, Maths block 50% Science Block, Technology Block, IT Room, Music Rooms, Sports hall, the dining room and "the street". Throughout that year, the English block was completed by Christmas and the playing fields by summer. In 1992 the school was completed at its next phase with art rooms, an extended maths block, Modern Language block, 6th Form Block, Meeting Hall and gymnasium all opening. Later extensions of the school involved a further extension to the art design and technology area and more recently an extended 6th form block. With the increasing popularity of IT part of the Maths block has become an ICT suite., the school plans to turn its original meeting hall into a sixth form area soon after a new extension is completed, in which there will be a new meeting hall and a new art, drama, and music department. The new extension is planned to be opened on Monday 13 April 2015.
Old site
Shortly after the move from Bletchley, the old school was demolished. However the site remained unused for some years before it was built on as an extension to the "Counties" estate in Bletchley.
