After the original building had been demolished, the name was re-applied to a modern office block on the same site which now serves as the headquarters of Slough Borough Council.

The original Observatory House was built, run and used by the astronomer William Herschel, and his sister Caroline.

[5] There is a poignant section of one of the early programmes by Sir Patrick Moore on BBC "The Sky at Night", which was aired in 1960.

[7] In the mid-1960s, the site was redeveloped with an office block, also called Observatory House, being erected there, while the adjoining road to the north was named Hershel Street in recognition of the astronomers.

The building was then refurbished by Kier Group[9] to a design by Elsworth Sykes Architects ("ESA") for developers, XLB, in 2017.
