The Marks and Spencer Pantheon flagship on Oxford Street has officially opened - fully transformed across four floors and almost 100,000 sq ft of renewed retail space. Halliday Fraser Munro was architect for the full store renewal as part of the wider design team.

Pantheon is M&S's R&D flagship - the blueprint that will shape the future of Fashion, Home and Beauty stores across the entire M&S estate. What's tested and proven here gets rolled out nationally. That's the scale of what this project represents.

From the fresh market-style foodhall to bespoke suiting, Beauty Hall, dedicated Kidswear and Lingerie rooms through to the Kelly Hoppen London homeware edit - every floor has been reimagined from the ground up while the store remained trading throughout.

A genuine landmark project on one of the world's most iconic retail streets.
