Ben Ainslie Racing HQ: A True Landmark
In the heart of Portsmouth Harbour, nestled on The Camber, stands a building that embodies ambition, precision, and sustainability the Ben Ainslie Racing Headquarters. Conceived as the nerve centre for Sir Ben Ainslie’s 2021 America’s Cup challenge, this prestigious facility is more than just a workplace; it’s a symbol of cutting-edge design and collaborative engineering.
A Vision Born from Challenge
The project began in mid-January 2014, when a multidisciplinary team was assembled to bring to life a headquarters that would house everything from boat manufacturing to crew facilities, offices, and a public visitor centre. With the site still undecided and the architectural concept in its infancy, the challenge was clear: deliver a world-class facility in just 17 months.
By March 2015, the manufacturing facility was operational. By June, the entire building was handed over on time and on budget. This feat was made possible by a unified team of architects, engineers, contractors, and specialists working toward a shared goal from day one.
Designing for Function and Flexibility
The building’s design was driven by the unique demands of the America’s Cup. The ground floor, tailored for boat manufacturing, features overhead cranes and high ceilings. Yet, the structure is far from utilitarian. The architect avoided a boxy form by tapering the north and south elevations and curving the eastern façade, creating a dynamic silhouette that reflects the elegance of sailing.
Each upper floor first, second, and third is uniquely shaped, reducing the building’s mass and offering expansive terraces. These open-plan spaces, flooded with natural light, are adaptable for future commercial use, ensuring the building’s longevity beyond its original purpose.
Sustainability at the Core
From the outset, the client aspired to achieve zero carbon status and a BREEAM Excellent rating. Thanks to the services consultant Couch Perry Wilkes, the building boasts an EPC A rating and complies with ISO 20121 for sustainable operations.
Key sustainability features include:
-
Photovoltaic installations for renewable energy
-
Rainwater harvesting systems
-
A sail-like fabric façade that provides solar shading and wind protection, enabling natural ventilation even in high winds
Engineering Excellence
With only 3.5 months from concept to construction, off-site manufacturing was essential. A structural steel superstructure was chosen for its adaptability, speed, and minimal foundation load critical given underground obstructions.
The steel frame also allowed for late-stage design changes, including the addition of mezzanine floors and a verendeel truss to support a suspended mezzanine. These modifications were seamlessly integrated thanks to 3D Building Information Modelling (BIM), which enabled real-time collaboration and rapid design iteration.
Smart Construction Solutions
Fire protection and corrosion resistance were meticulously planned. Using ISO12944 classifications, the team tailored a factory-applied coating system for each steel section, eliminating the need for on-site application and optimizing cost and performance.
Floor construction was another area of innovation. After evaluating various options, the team selected in-situ concrete on metal decking for its balance of cost, speed, and structural efficiency.
A Model for Future Projects
The Ben Ainslie Racing HQ is more than a building it’s a blueprint for how ambitious timelines, complex requirements, and sustainability goals can be met through collaboration, innovation, and precision. As Portsmouth continues to evolve, this landmark stands as a testament to what’s possible when vision meets execution.

Development Viability: An Increasing Area of Focus for SME Housebuilders
July 10, 2026
The development landscape continues to evolve. Planning policy, infrastructure requirements, utility capacity, environmental obligations and market conditions are all influencing how residential schemes are assessed, planned and delivered. Against this backdrop, the Home Builders Federation's latest SME Developer Sentiment Survey highlights development viability as an increasingly important area of focus for SME housebuilders. For a sector that plays a critical role in delivering much-needed housing across the UK, the findings provide a valuable snapshot of the factors influencing investment decisions, land acquisition strategies and project delivery.
Transfer Slabs Under the Spotlight
June 19, 2026
Transfer slabs are a key component in complex structural design, and evolving regulatory expectations are strengthening how their performance is understood and demonstrated. This article shares our perspective on the Building Safety Regulator’s focus on transfer slabs, outlining what it means for new and existing buildings, and highlighting the value of clear, evidence-led design and proportionate engineering judgement.
Brookbanks Podcast #19: Life Cycle & Upfront Costs
June 18, 2026
As the long-term sustainability and operational efficiency of developments come under greater scrutiny, the balance between initial capital outlay and long-term expenditure is playing an increasingly important role in successful project delivery. In our latest podcast, “Life Cycle & Upfront Costs,” Ben Wakeling is joined by Gerrad Mukuyu to explore how these two critical aspects of project budgeting interact in practice. The discussion focuses on why evaluating a project's financial footprint over its entire lifespan rather than just its construction phase can improve scheme viability, reduce risk, and ultimately create more sustainable, cost-effective assets.
