The building also hosts some of the observatory's scientific instruments on its roof.
The University of Hertfordshire use the site as their biology and geography field station.

John Innes Centre
The 372 acre Bayfordbury estate was bought by the John Innes Centre in 1948 where it was developed into a School of Cytology. A new Cell Biology building was built in 1959, which would later become the Science Learning Centre. In 1967 they moved to their present site at Norwich, and the Bayfordbury estate was bought by the University of Hertfordshire.
The Clinton-Baker Pinetum is a 10 acre pinetum containing over 150 species of conifers from all over the world, many over 100 years old. The first conifers were planted in 1767 by Sir William Baker, the original owner of the mansion, and is now currently being restored by volunteers.
