Founded in 1845, Brighton College is a leading boarding and day school with over 1500 pupils. Consisting of four floors totalling 28,000 sq ft, the building’s design is based on a similar building at Yale University. Only 2mm of movement was experienced during the entire demolition and construction.

The building is constructed of stone and brick in keeping with the surrounding buildings, using Limetec Hydraulic Lime mortar – Limepoint and of concrete frame construction on a raft foundation and clad in tradition flint work, brick and curtain walling.

Located near the historic Front Quadrangle next to several Grade II listed buildings (including the adjacent Great Hall), The Kai Yong Yeoh Building is distinct and of a high-quality, and has replaced several outdated structures on the site. The building's scale and massing respects the historic context of the highly constricted campus and is five storeys high, of which 1 to 1.5 storeys are partially hidden below ground. The building has been designed to achieve a BREEAM Excellent rating.
