Walton High is a large academy school with two campuses located in the Walnut Tree and Brooklands areas of eastern Milton Keynes in Buckinghamshire, England.

In September 2000, a new Art and Design Technology block was added to the site to accommodate new pupils and provide new learning opportunities.

In late 2006, plans for a new "state of the art" sixth form area to replace the temporary one, and a sports pavilion/dance studio (including a bar) were approved to be added onto the adjoining grass land.

In September 2007, the Post-16 Centre opened, providing a base for approximately 400 students pursuing a variety of academic and vocational courses.

Technically, the theatre is equipped with “a 12m x 9m stage, fly tower, orchestra pit, Green Room, state-of-the-art sound system and lighting rig”.

Over the summer, and Autumn Term 2011, a new mezzanine floor was added to the café area; thus significantly increasing available space, creating the upper-café.

[15] Both campus libraries are open from 08:00-16:00 for students and are well-stocked with a range of fiction and non-fiction texts, newspapers, magazines and periodicals, and a reference section of all core textbooks.
