With regard  to the issue of rationalization of public spaces, the example is implemented by  the UK State is the most representative.
Before the beginning of the millennium, UK central Government didn't focus  on how accommodation should be managed. But according to  White (2011), two  reports "Measuring Performance in the Management of Local Authority  Property: A Research Report" (1999) and "Hot Property: Getting the  Best from Local Authority Assets" (2000) emphasized that real estate  should be a means of more efficiently delivering services to users and that a  more strategic focus was required in the management of real estate portfolios.
The first projects, about pro-active real estate management, were to office  use resulted in more focus on how much accommodation was being used by central  government; the Gershon Report (2004), which recommended cost reduction programs,  estimating a save £20 billion after four years. The UK  Government and the Office of Government Commerce (OGC) developed asset  management templates to be used by government departments in preparing their  own asset plans.
According  to the report "Improving Asset Management in the Central Civil  Estate" (2006):
"the savings in  central government real estate costs of over £150 million were possible with  additional efficiency savings of up to £380 million per annum from flexible  workplace and workstyle strategies".
At the same  time, the report “A Route-map to Asset Management Excellence” suggested several  recommendations such as clear asset management responsibilities within  departments, the use of performance metrics to track progress and efficiency in  accommodation use with the disposal of surplus space and the adoption of space  saving workplace strategies.
According  to Deloitte in “Office politics.  Improving public sector property management” - a real estate study of UK public  -  the application of this strategy  has saved £190 million in UK government. This public real estate strategy is to  strengthen management capability across their corporate and operational estate,  centralizing finance and administration functions.
According to the report “Government’s  Estate Strategy” by Cabinet Office" (2014) the project involves several actions  including: to remove boundaries between departments, local authorities and  other public bodies, to minimise need of office space, efficient use of  existing resources, to get rid of surplus in a way that maximises receipts and  boosts growth and creates new homes. From 2010 to 2014  departments have shrunk the central Government estate by over two million  square metres.
“[...] That reduction has  saved us £600 million a year in running costs and has brought in a cumulative  £1.4 billion (since May 2010) from the sale of a wide variety of land and  buildings, not just offices”.
