Marlborough House comprises a detached Victorian Villa, originally constructed in 1880 as a single dwelling. It has been most recently used as a HQ office facility, with a two-storey flat roof extension to the Southern elevation of the site which was added in 1958. The property features a yard area suitable for parking to the front of the property overlooking Northumberland Road.
The interior of the property remains in its original configurations, with accommodation split across 3 storeys and featuring a basement storage area.
