What is being bought

Following our 200th anniversary celebrations, we are launching a landmark architectural competition for the design of a transformative new wing and public realm. Our ambition is to create an architecturally distinguished, sustainable, and state-of-the-art new wing and public space. The new wing will be built on the last remaining part of the National Gallery campus: St Vincent House. The property was acquired nearly 30 years ago, for the purpose of expanding gallery space, and currently houses a hotel and office complex. The project aims to invigorate this corner of central London, connecting Trafalgar Square and Leicester Square. Embedding the Gallery as a cornerstone within London's arts quarter, it will also cement our reputation as a leader in the art world and the UK's commitment to culture and heritage. The purpose of this competition is to find exceptional architects to take on the extraordinary responsibility that designing this new wing will entail.

The property was acquired nearly 30 years ago, for the purpose of expanding gallery space, and currently houses a hotel and office complex.\nThe project aims to invigorate this corner of central London, connecting Trafalgar Square and Leicester Square. Embedding the Gallery as a cornerstone within London's arts quarter, it will also cement our reputation as a leader in the art world and the UK's commitment to culture and heritage.\nThe purpose of this competition is to find exceptional architects to take on the extraordinary responsibility that designing this new wing will entail.",

    "description": "Following our 200th anniversary celebrations, we are launching a landmark architectural competition for the design of a transformative new wing and public realm.\nOur ambition is to create an architecturally distinguished, sustainable, and state-of-the-art new wing and public space.\nThe new wing will be built on the last remaining part of the National Gallery campus: St Vincent House. The property was acquired nearly 30 years ago, for the purpose of expanding gallery space, and currently houses a hotel and office complex. \nThe project aims to invigorate this corner of central London, connecting Trafalgar Square and Leicester Square. Embedding the Gallery as a cornerstone within London's arts quarter, it will also cement our reputation as a leader in the art world and the UK's commitment to culture and heritage.\nThe purpose of this competition is to find exceptional architects to take on the extraordinary responsibility that designing this new wing will entail. The selection of an architectural team will take place in two stages:\nStage 1: An open call for expressions of interest from architects that believe they meet the criteria specified in the competition brief.\nStage 2: Up to six architects will be shortlisted and will be asked to expand on how they might approach this specific project.",
