A £12m investment that has doubled the size of a gallery hopes to capture of the original "spirit" of the new town it is built in.
MK Gallery, on Midsummer Boulevard, in Milton Keynes, is reopening after nearly two years of work.
The new building has been created to "reflect the city's original grid" as well as the "geometries" of nearby Campbell Park, the gallery said.
It now features five exhibition galleries, a new auditorium and studio.
The original gallery was opened in 1999 and has been incorporated into the new version.
Anthony Spira, director of MK Gallery, said it was in keeping with the town, which was born with an Act of Parliament in 1967.
"In the spirit that created Milton Keynes, the new MK Gallery, on its 20th anniversary, aims to reinvent the idea of the art centre for our own time," he said.
"Both radical and inviting, serious and playful, it is fully accessible and the kind of building where I hope everyone will feel welcome."
The gallery will provide spaces for major exhibitions, films, music, performance, family events, workshops and social spaces, it said.
It was paid for by lottery money, Milton Keynes Council, South East Midlands Local Enterprise Partnership, along with MK Gallery funds.
