The Music Centre is a joint venture by Watford Grammar School for Boys and Hertfordshire County Council, providing new music facilities for the school and the county, and a public music centre for the region.

It contains a recital hall and 24 music teaching spaces - and at full capacity holds 400 people making or listening to music. Clad in translucent glass, the building sits lightly between the trees on the lawn in front of the School. The project was funded by enabling housing development designed by Tim Ronalds Architects on an area of surplus School land.
