Interview: James Denby - The Barbican, One Year In

A whole year has gone by since Greenway Associates was appointed as Cost Consultant for the Barbican Renewal Programme. We caught up with Project Manager and Cost Consultant James Denby, who has been working on the project. With particular expertise in building services, James offers a unique insight into the progress made so far and the complex infrastructure that underpins one of London's most iconic cultural buildings.

While visitors experience the Barbican through its theatres, galleries and public spaces, much of the Renewal Programme focuses on the unseen systems that keep the Centre operating every day. From major building services upgrades to long-term cost planning, James explains why some of the most important work happens behind the scenes.

GA: One year into the programme, how would you describe the journey so far?

James:

GA: When people think of the Barbican, they often picture the architecture. But much of this project is about what's hidden behind the walls. Can you explain why that work is so important?

James:

GA: The programme includes extensive upgrades to the building's services infrastructure. What makes this such a significant undertaking?

James:

GA: It's been suggested that around £100 million xxxx (do we mention figure?) of the programme relates to infrastructure and building services. Why is so much investment needed in areas visitors may never see?

James:

GA: As Greenway's resident MEP specialist, what are some of the biggest challenges in planning costs for building services on a project like the Barbican?

James:

GA: How do you replace essential systems in a building that welcomes millions of visitors while respecting its Grade II-listed status?

James:

GA: From a Cost Consultant's perspective, what makes the Barbican one of the most technically challenging projects you've worked on?

James:

GA: Looking back over the first year, what achievements are you most proud of?

James:

GA: The project brings together architects, engineers and specialist consultants from many disciplines. What has collaboration looked like over the past year?

James: (chance to mention Allies and Morrison etc)

GA: Looking ahead, what are the team's priorities as the project moves into its next phase?

James:

As the Barbican Renewal Programme enters its next stage, the focus will continue to shift from planning into delivery. Subject to planning approvals, the programme is expected to progress through detailed design before major construction begins in 2027. Phase 1 includes significant improvements to the Foyers, Lakeside, Conservatory and surrounding public spaces, alongside extensive upgrades to the Centre's ageing infrastructure.

For Greenway Associates, the next chapter is about continuing to support the project team as the programme moves towards delivery. While many visitors will one day enjoy brighter foyers, an enhanced Conservatory and improved public spaces, much of the Renewal's greatest achievement will remain largely unseen: modern, resilient infrastructure that will allow the Barbican Centre to thrive for decades to come.
