Restoring a building of national importance is never just about construction alone. At Ten Trinity Square, that balance meant preserving over a century of history while quietly integrating the infrastructure required for modern luxury living.

Originally built in 1922 as the headquarters of the Port of London Authority, this imposing Portland stone landmark once functioned as the control centre of Britain’s global trade network.

Today it offers a very different kind of experience. One of five-star hospitality as the Four Seasons Hotel London at Ten Trinity Square.

A Building That Demands Respect

Ten Trinity Square is a Grade II* listed building. This places it among the UK’s most protected buildings, meaning any and all alterations must be handled with extreme care.

Behind its grand façade (once designed to impress global merchants) lies a structure that has witnessed defining moments in history.

Transforming such a building into a luxury hotel required a “modern antique” approach: preserving architectural integrity while embedding contemporary systems that guests never see but we all fully rely on.

Our Scope

Abbey Pipework Fabricators were responsible for delivering:

• • Low Temperature Hot Water (LTHW) systems

• • Chilled Water (CHW) systems

• • Gas pipework systems
    

Across pipe sizes ranging from 2½” NB to 12” NB, the installation formed the backbone of the building’s heating, cooling, and energy distribution (something guests would not have been thankful to miss).

In a modern hotel, comfort is expected to be seamless. Instant hot water, perfectly controlled room temperatures, and reliable services throughout. Achieving this in a heritage structure poses its own challenges. It requires precision planning and expert fabrication.

The Challenge: Modern Systems in a listed building

Unlike new-build projects, heritage restorations don’t offer the benefit of designing around services. Instead, services must adapt to the building.

At Ten Trinity Square, that meant:

• • Working within existing structural constraints without compromising historic fabric.

• • Routing large-diameter pipework discreetly through complex spaces.

• • Coordinating with multiple trades to ensure smooth delivery.

• • Maintaining performance standards expected of a world-class hotel.

Engineering Invisible Luxury

Guests at the Four Seasons experience the end result without ever seeing the systems behind it. This is something we find fascinating at Abbey.

The work we do operates with a quiet efficiency.

That’s the hallmark of successful pipework in hospitality: if you notice it (without it being a feature of the building), something’s wrong.

Building the Future Inside the Past

Heritage projects require respect.

Respect for the structure.

Respect for its history.

And respect for the standards of modern performance.

At Ten Trinity Square, that balance was achieved creating a space where history and engineering work side by side, seamlessly.
