Construction has officially begun on one of Prague’s most technically difficult development projects, as developers Penta Real Estate and PSN move forward with Vinohradská 8 on the former Transgas site near Wenceslas Square.

The project has drawn attention for years because of its prominent position and the demolition of the controversial Transgas complex that once occupied the land. The new development will include apartments, offices, retail space, and public areas.

According to Penta co-founder Marek Dospiva, the site presents engineering challenges rarely seen in Prague construction projects. Parts of the building are being constructed directly above the Vinohrady railway tunnels, leaving builders with almost no margin for error.

The location also borders the headquarters of Czech Radio, forcing developers to meet strict technical conditions to avoid disrupting broadcasts during construction.

For Prague-based developer Penta Real Estate and PSN, the development is also intended to repair a long-disconnected section of the city between central Prague and Vinohrady.

PSN chief executive Max Skala said the site had remained an unfinished gap in the urban landscape for years. He described the project as an attempt to reconnect an important part of the city while introducing new housing and office space into one of Prague’s busiest districts.

The project will also include a public art component, continuing a strategy Penta has used in several recent developments across Prague. An international competition has already been launched to select an artwork for the site.

According to Dospiva, art is no longer viewed simply as decoration within major development projects. Instead, it has become part of a broader effort to create public identity and strengthen the connection between private developments and the surrounding city.

Local officials from Prague 2 Municipal District have supported the project after negotiations over public benefits connected to the development.

Deputy Mayor Jan Recman said the developers agreed to contribute financially toward the reconstruction of the Smetanka elementary school and also incorporated environmental measures into the project.

The plans include green roofs, landscaped areas, and blue-green infrastructure designed to improve water retention and reduce heat in the dense urban environment.
