Architecture firm UNStudio has designed an office in St Petersburg which will contain an atrium that rises diagonally through the building.

UNStudio designed the large office building on the St Petersburg waterfront overlooking the Gulf of Finland for Czech software company JetBrains.

The office will be built alongside JetBrains’two existing buildings and will be comprised of two stepped volumes unified by a gridded facade.

This gridded design will be created from protruding ceramic panels, which both reflect the light and provide shade to the interior.

The two volumes will be divided by a zigzagging glass wall that stretches diagonally across the entire central part of the building and contains a large multi-level atrium, which stretches up to five storeys at its highest point.

The upper part of the building extends over the office atrium to provide shade to the interior.

Inside, the lobby will incorporate large planters, green walls and hanging plants, and open up towards the atrium.

The stepped atrium is at the centre of the design and will form the core of the office, with the aim to create flexible workspaces as well as spaces for social interaction.

The atrium connects different levels of the building

Meeting rooms, breakout spaces, auditoriums and a restaurant will all be organised along the atrium while winding bridges will extend across the open space and connect different parts of the design.

Office floors will largely be housed in the upper volume of the building and will be organised around both individual and team working spaces.

Terraces create spaces for overflow working for JetBrains

“We pay a great deal of attention to how people move through buildings,” said UNStudio founder Ben van Berkel.

Office spaces are designed in such a way that they do not create simple linear corridors leading to dead ends, instead, each corridor has a route that introduces a kind of landscape into the building,” he continued.

“The possibility is created to take endless walks through the building, where there is a great deal of transparency, also towards the surrounding landscape.”


The atrium‘s stepped design will extend from the interior to the exterior of the building to form a series of curved, staggered terraces and courtyards.

A courtyard on the ground level will connect UNStudio‘s design with JetBrains’ existing office buildings, as well as provide the office with a gallery space that can be used as a winter garden for outdoor plants.
