Block 4 is the fourth block that is developed by KCAP+Orange within the masterplan for Vasilievsky Island in St. Petersburg. The first two blocks, Block 6 and 7 are already under construction and Block 8 under development. In contrast to the residential and commercial program of the rest of the Blocks, Block 4 will be developed into a promising business card of the Golden City project along the city ring road.

Block 4 with its exceptional design stands out and manages to tackle the multiple challenges that were set, as it is not only successfully providing a complex functional mix of spaces (office center, commerce, kindergarten, multistory parking buildings etc.) but it is also perceived as a coherent environment and harmonious part of St Petersburg city, using the full potential of its site and location.


‘..The flexible and interactive office buildings are integrated with green to offer a unique experience of divers and sustainable working spaces..’

The concept of Block 4 urban layout is based on a mosaic ‘carpet’ of landscape and buildings that spreads along the whole site. Separate land plots are the integral components of this ‘carpet’. Its separate land plot consist of a network of green plazas between the solitaire buildings connected through walking routes and shared space streets.

The architectural and urban-planning concept contains a great degree of flexibility with regard to building facades: the possibility of refining the design of facades without losing the integrity of the ensemble. The facade tool kit consists of various options in three main categories: type and area of glazing, color and the second skin. The client for individual buildings can influence the design of façade.

The proposed design is also focused into creating a sustainable and green environment, enhancing the well-being of the people who live and work in them, help protecting natural resources and making the development more attractive for property investments.

An organized network of bicycle lanes connects Block 4 offices to Block 6, 7 and 8 residential development, all the way to the tip of the island and the active waterfront of Block 9.

Routes and plazas throughout the development are designed as an eco-friendly landscape, with rain gardens and aqua flow pavement that focuses on the most sustainable management of water and rainwater.

Moving up from the ground level to the terraces, the roof space of the new buildings is organized into smaller or bigger terraces with special program, but in most of the cases the roof space is occupied by solar panels, which function very well in the climate of St. Petersburg, and by green roof. The green roof is an essential element of an eco-building.

Microclimate, low energy consumption, water storage and efficient management are prominent aspects of designing for BREEAM certificate.
