7 Since 1998 when the Home Office stated its requirement and invited Best and Final Offers, the Home Office has experienced significant growth in Home Office and Prison Service central London headquarters staff numbers from 3200 to 4900 at present. The new building will be able to hold up to 3450 staff. Current projections for 2005 are subject to review but if numbers remain constant, it will not be possible to accommodate all Central London Home Office headquarters staff, including those employed by the Prison Service, in 2 Marsham Street. A range of options for accommodating the excess are currently being considered aimed at ensuring numbers in Central London are no larger than necessary but there are no firm proposals at present.
