I have been looking for somewhere to base an office in North London near Islington, as I am expanding my operations and need a work space near town.  I have come across a set of light industrial units which will provide me with the space and flexibility that I need.  These are on the first floor and offer the security for my IT equipment as well as space for storage.  Grenville Workshops in Islington still have a number of units to let and are worth considering if you need space is this area.
