Sayart / Nov 14, 2025

Architecture firm Barr Gazetas has secured planning approval to undertake a comprehensive restoration and extension project of a significant 1970s office building designed by renowned architect Richard Seifert in London's Bloomsbury district. The project represents a major preservation effort for one of the area's most distinctive architectural landmarks from the modernist era.

The building, which stands as a testament to Seifert's influential architectural legacy, will undergo extensive restoration work to preserve its original character while incorporating modern additions that will enhance its functionality for contemporary use. Richard Seifert, known for his prolific contributions to London's skyline during the 1960s and 1970s, designed numerous iconic structures throughout the city, making this preservation project particularly significant for architectural heritage.

Barr Gazetas, the London-based architecture practice, will oversee both the careful restoration of the existing structure and the design of new extensions that complement the original building's distinctive modernist aesthetic. The firm has demonstrated expertise in working with historic buildings while incorporating contemporary elements that meet current building standards and user requirements.

The approval comes after what was likely an extensive planning review process, given the building's architectural significance and its location in central London's Bloomsbury area, which is known for its rich architectural heritage and cultural institutions. The project will need to balance preservation requirements with the practical needs of modern office users.

The restoration and extension work will breathe new life into this important piece of London's architectural history while ensuring its continued relevance for future generations. The project demonstrates the ongoing value placed on preserving significant modernist architecture from the post-war period, particularly works by influential architects like Richard Seifert who helped shape London's contemporary urban landscape.
