We have been appointed to deliver an eight floor, 42,000 sq. ft, £25m fit out with complex structural refurbishment in London’s West End.

The team has developed a carefully sequenced refurbishment programme that will lead seamlessly into a high quality Cat B fit out, including the transformation of the roof, which will provide a new social green terrace space.

Demolition and temporary propping are currently underway and over the coming months, works will move into the internal structural alteration phase to reshape the building’s internal structure, creating open floorplates with glazed meeting rooms suited to modern office occupation.

For the past 12 months, our Project Directors, Divisional Commercial Directors and Commercial Managers have taken part in a leadership development programme designed to build high-performing leaders who can drive team alignment, improve project outcomes and support consistent delivery across our projects.

Through a series of workshops and applied learning sessions, The Work of Leaders has helped participants develop a deeper understanding of leadership styles, communication, and how behaviour directly impacts performance on site and across teams.

For each participant, it has been a rigorous 12 months - balancing project commitments while stepping up to the next level of their development - and we want to say a huge congratulations to all of them.

Our business is underpinned by the quality of our people. This continued investment supports their growth, and in turn strengthens the teams around them and the projects we deliver.

Congratulations to everyone who took part.

The Gherkin’s natural ventilation system is one of its most sophisticated engineering feats.

It is inspired by The Venus Flower Basket, a deep-sea sponge that has a lattice-like skeleton designed to channel water currents for feeding and stability.

Our fit out delivery across 25 floors of the building means we have intricate operational knowledge of how to make it work efficiently and effectively. Some of its standout features include:

Spiralling light wells run through the building, forming its structural and environmental spine.

A natural “stack effect” draws air through the floors, allowing the building to breathe.

Automated windows respond to real-time weather conditions, supporting the HVAC system.

Delivering within this environment demands more than standard fit out expertise, it requires understanding of how to:

Protect airflow - ensuring partitions and layouts don’t disrupt how the building breathes.

Work with geometry - circular floor plates require bespoke detailing and coordination.

Maintain fire integrity - managing open voids and fire breaks with precision.

Navigate logistics - delivering in a high-security, zero lay-down environment.

Control acoustics - managing sound transfer across interconnected floors.

In 30 St Mary Axe, each fit out was designed with specialist services to create a comfortable, workable environment, with some of the best views in the city.

How do you restore the unrestorable? At 63–66 Coleman Street, a small but technically demanding part of our scope – the replacement of heritage iron Juliet balcony balustrades formed from interlinking circles – became a defining feature of the project.

Originally deemed unrestorable, our team re examined this detail in close collaboration with Emrys Architects, leading a technical analysis to ensure it could be replicated, installed and maintained within a retained façade.

Each application was tested and refined across multiple iterations, with close scrutiny of geometry, spacing, scale, materials and fixings.

This went beyond aesthetics: we assessed every circle against guarding requirements, fall prevention standards and health and safety compliance, particularly as the motif increased in size and appeared in different locations and materials across the building.

The final result is a complete integration of the circles throughout the asset, from a curved stone reception wall to terrazzo flooring, bespoke lighting, lift lobbies, planters, balustrades and a new rooftop terrace. Working in partnership with the architect, we delivered precisely what the client envisioned - a heritage feature restored, preserved and realised as stated in the design intent.
