Polish Ministry of Infrastructure and UK's Department of International trade have signed an agreement which envisages readiness for cooperation on Solidarity Transport Hub (CPK) – involving a Polish-British consultation team - on designing airport and rail infrastructure, spatial planning for areas around the airport and issues relating to sustainable development and project digitization.

In June and September 2019, British Embassy Warsaw hosted workshops that paved the way for initial architectural concepts for the Solidarity Airport. The proposals were submitted by internationally renowned architecture firms Foster+Partners, Chapman Taylor, Zaha Hadid Architects, Grimshaw, Benoy, Pascall+Watson, Woods Bagot, Populous and KPF.

The British aviation sector has much experience and know-how to offer toward planning, designing, and building the Solidarity Airport and 1600 km of new railway lines including high-speed lines.

The Solidarity Transport Hub is a planned transfer hub in the centre of Poland which will integrate air, rail and road transport. The scope of the project includes the construction of an airport located 37 km west of Warsaw and covering an area of 3,000 ha. The new airport will initially be able to handle up to 45 million passengers per year, with the potential for this to increase to up to 100 million.

Bird & Bird will act as advisers for the contracting authority of the project and help in the process of selecting key consultants.
