At Capital 8 in Paris, Invesco is repositioning a key asset through the introduction of a new hospitality model, strengthening the building’s long-term relevance.
As part of that strategy, we led the technical design and delivery of new public-facing amenity spaces within the live commercial environment, helping translate the wider vision into an operationally robust reality.
Invesco required a delivery partner capable of managing the complex stakeholder environment with autonomy, accelerating decision-making across the programme. The client retained responsibility for asset-level decisions and investment direction.
We acted as the single point of delivery and technical leadership, managing day-to-day technical coordination and regulatory engagement, while leading operator management across design and construction phases.
The scope comprised 3,000 sq m of amenity space within a 45,000 sq m commercial building, delivered by our Paris team working directly for Invesco, with JLL supporting as client-side project manager.
A defining aspect of the project was the change of use from private office space, governed by Code du Travail regulations, to publicly accessible Établissement Recevant du Public (ERP) functions. This transition fundamentally altered the regulatory framework, introducing more stringent requirements around fire strategy, evacuation, accessibility and building services.
We led the planning and administrative process, coordinating ongoing dialogue with local authorities. A phased approach allowed regulatory approvals and technical development to progress while the building remained operational.
The project combined multiple distinct environments, including a business and events centre, hospitality-led restaurant spaces and a gym, each shaped by different operators and design teams. This created a complex, multi-party delivery landscape.
Partial plan of one level showing the addition of the restaurant, business centre and gym. We coordinated these varied concepts through a commercially aligned delivery strategy. This resolved technical and budgetary requirements while maintaining the intent of each operator-led design. Despite differing operator briefs and material palettes, the finished environments read as cohesive, technically resolved and consistent in quality.
Our technical leadership extended across full MEP design and coordination, specialist systems and due diligence. This included high-capacity HVAC solutions for the gym, professional kitchen design and extraction systems, and advanced AV environments within the business and events centre.
These systems were fully integrated within refined architectural environments, requiring precise coordination between structure, services and finishes.
The programme also required careful integration of specialist installations, such as a climbing wall, alongside flexible event spaces capable of supporting conferences, dining and evening use.
"Capital Lounge" activating the building at street level. Where early design ambitions conflicted with base build constraints or local regulations, we led collaborative iterations with the designers to develop alternatives.
For example, the original restaurant concept centred on a charcoal grill. Technical studies and dialogue with authorities ultimately confirmed this was not viable, but the design and delivery team developed a revised solution that maintained the intended dining experience while meeting stringent fire and ventilation requirements, preserving both design quality and compliance.
Through early cost validation and technical development, we rationalised materials and building systems within operator-led concepts. This reduced late-stage redesign and delivered approximately 10% cost savings, ensuring that premium finishes and specialist installations were delivered without compromise.
From technical design commencement to operational readiness, the project was delivered over a 15-month programme. Adopting a single-point delivery route reduced the anticipated timeline by three months compared to a traditional multi-consultant model.
Earlier completion enabled faster operation of the amenity spaces and earlier revenue generation.
The completed amenities now operate as flexible destinations capable of supporting events, dining, fitness and a range of other activities. Together, they enable more intensive use of the building within the Paris market.
Ultimately, by leading the project end to end, we supported Invesco in this landlord-led asset transformation, assuming responsibility for technical and delivery risk while maintaining control over cost, programme and operational readiness. The result is a technically robust, high-specification amenity offer delivered within a live, multi-let asset.
