Reclassification of office properties 2020

The members of the Prague Research Forum – CBRE, Colliers International, Cushman & Wakefield, JLL and Knight Frank – have undergone a reclassification process of all properties, which are currently included in Prague’s office stock to better reflect modern trends in property and development.

Minimum requirements

The minimum requirements for inclusion into modern office stock of either Class A or Class B have remained unchanged and include:

  • The building was built or refurbished after 1990
  • Available units are being advertised in an appropriate way
  • The GLA of the building exceeds 1,000 sq m

Major categories

When assessing the property quality, the major categories included are as follows, with brief description:

  • Technical specifications – how well is the property built and equipped
  • Smart technologies – how efficient the buildings are, what smart technologies do they use and what extras to “standard” property equipment do they offer
  • Location – accessibility, services and amenities in a proximity of the property
  • Service and security – how safe the building is and how is it managed
  • Parking – parking ratios, with different requirements for properties in the city centre, inner city and outer city
  • Age of building – building completion or the latest refurbishment date
  • Subjective evaluation – subjective assessment by Prague Research Forum members


Each of the criteria has subcategories, which enable scoring of the properties, resulting in final score of the property. Maximum weight of each category is as follows:
