Hamburg with the quantity of about 18 mlns m2 is, alongside with Berlin and Munich, the biggest office centre in Germany. The large-scale planning and urban operations with the aim of location this function in the centre have been carried out since the beginning of the '60s. The policy of deployment the ofiice sites has beez modified since then, from isolating the monofunctional area of the Modernism's spirit, to multifunctional structures interplaying with the other sites when it comes to activities' potentiality with the expansion of the large-scale urban structures. Many recent realisations abound with significant buildings that bring the avant-garde approach to the idea of an office building. The high level of building technology and the importance of ecological aspects are the important distinction. The mentioned realizations has been noticed by the architectural critics and mentioned in professional press. The pride of place belongs to the works of BRT (Bothe-Richter-Teherani), that has created many innovatory office buildings.

Since the ’70 Vienna has taken up the political, economic and planning actions heading to make the city the significant European business centre. The mentioned above has been realised by development of the modern workplaces connected with generating, transforming, distributing and commercialising information, it is to say by developing the office and conferencing functions. The first was built the Uno-City, then it was recreated into the multifunctional business plot with the office function as the main, namely the Donau-City. With the business area of more than 11mln squaremetres, Vienna is the biggest centre of this type in the eastern part of the European Union, and within the limits of Donau-City there have been risen many interesting architectural objects. The six of them are presented in the article.

The East of Europe stays at present on the background of interests in the new architecture. Meanwhile Moscow is a major city of Europe and there many interesting implementations are occurring. For her the office market intensively is being extended, at least in contrast with countries of the free market democracy, it is playing the political factor there major part. From interesting implementations they mentioned the Moscow International Business Centre as about the big urban planning operation and about Dominion Building Office as about interesting Zaha Hadid work.

Due to the ongoing climate change, the issues currently in focus are the reduction of CO2 emissions into the atmosphere and sustainable construction. The search for ecological alternatives to traditional building structures that will reduce a building’s carbon footprint seems to be a desirable direction of modern construction development. At present, the first projects of office buildings that use cross-laminated timber as the main construction material are being completed, which can have a positive impact not only on the environment but also on the users of the building.

The on-going economic transformation of the Moscow market towards the provision of services and trade requires the revitalisation of many districts. The case study — the Dominion Tower building — shows that solutions in the field of architecture and urban planning of buildings whose construction can be categorised as local architectural intervention into existing urban structure may be decisive in the success of an undertaking aimed at activating urban tissue within the interference area.

The increasing demand for office space in Moscow, as well as the economic and political conditions in the global context, have contributed to the construction of a multifunctional complex of the Moscow International Business Centre in the Russian capital. The primarily office building complex is an example of activities consisting in the degleration of offices outside the city centre. It is also an attempt to create a prestigious place (including attractive architecture), an element of the city identity indicating a high development level of the state, application of new solutions in the fields of urban planning and architecture (including technique and modern technologies).
