Elegance in Black: City Concepts x Cleveland House
TP Bennett’s design, Box3’s execution, and City Concepts’ Concept54 Double System combine to transform Cleveland House for a leading investment firm.
In the prestigious St James’ district of London, at Cleveland House, 33 King Street, a recent project stands as a testament to City Concepts’ commitment to excellence and trusted partnerships. This July, we are proud to spotlight our collaboration with Box3, TP Bennett, and Forza on Phase 2 of an exceptional 7,500 sq ft commercial transformation for a renowned global investment firm. This project not only showcases our technical expertise and aesthetic precision but also highlights the value of enduring client relationships and proven performance.


The Power Of Proven Partnerships
There is perhaps no greater endorsement than a client choosing to work with you again. Following the successful completion of Phase 1, City Concepts was the natural choice for the client team when embarking on Phase 2 of the Cleveland House project. Working alongside the same exceptional team – Box3 and TP Bennett – we were tasked with delivering a sophisticated glazing solution that would maintain consistency with the existing office floor while enhancing the acoustic performance and visual appeal of the space.
This repeat collaboration speaks volumes about the trust placed in our expertise, the quality of our systems, and our ability to deliver exceptional results. As specialists in commercial fit-outs, Box3 brings innovative approaches to modern workspace development, while TP Bennett, with over 100 years at the forefront of architecture and design, contributes world-class design vision. Together, we formed a seamless partnership focused on exceeding the expectations of our discerning investment sector client.


Harmonising Performance with Luxury Materials
The brief for Cleveland House demanded both aesthetic refinement and acoustic performance – essential requirements for a high-profile investment firm where confidentiality and focus are paramount. Rising to the challenge, City Concepts deployed a carefully curated selection of our market-leading systems. The majority of partitions featured our Concept54 double glazed screens with an impressive 46dB Rw acoustic rating, while feature glazed fins were installed using Concept100 double glazed screens achieving an enhanced 48dB Rw for superior sound insulation.

The visual impact of the installation was carefully considered, with all partition frameworks finished in elegant Black RAL 9005, creating a bold, contemporary aesthetic befitting a leading financial institution. Complementing these sleek lines, all doors and frames were crafted in sumptuous Crown Cut American Black Walnut, perfectly matching the client’s existing office floor for a cohesive visual narrative throughout the space.


Innovative Integration: The Forza Partnership
A standout feature of this project was our collaboration with Forza, the UK’s leading manufacturer of bespoke timber fire doors and joinery. This partnership exemplifies City Concepts’ commitment to delivering integrated solutions that combine the best of British craftsmanship. All doors for the Cleveland House project consisted of Forza timber doors and frames, achieving 38dB Rw acoustic performance while maintaining visual harmony with the existing space.


Our partnership with Forza allows for remarkable flexibility in door integration. For Cleveland House, we utilized timber frames and doors to match the client’s current system, but our collaboration enables multiple approaches – from full timber solutions to hybrid designs incorporating our own frames for a more industrial aesthetic. This versatility ensures we can meet diverse design requirements while maintaining acoustic integrity.
One door in the installation required special attention – a fully automated door closing system to ensure building standards compliance. This necessitated close coordination with a specialist automation contractor, showcasing City Concepts’ ability to navigate complex technical challenges through effective collaboration and meticulous planning – an approach particularly valued in the exacting world of investment and private equity.

British Manufacturing Excellence
At City Concepts, our commitment to British manufacturing excellence underpins everything we do. The Cleveland House project benefited from systems designed and fabricated in our UK facility, ensuring stringent quality control at every stage. This local production capability not only guarantees superior craftsmanship but also enables the responsiveness and flexibility essential for bespoke projects like this one.
Our partnership with Forza further strengthens this British manufacturing ethos. As specialists in the preparation of wood veneers and timber for doors, frames, and associated joinery, Forza shares our dedication to quality, precision, and sustainable practices. Together, we represent the best of British design and manufacturing expertise – a value proposition that resonates strongly with discerning clients in the financial sector.
A Testament to Collaboration and Expertise
The successful delivery of the Cleveland House project within a 4-week timeframe (as part of the overall 12-week programme) is a credit to the seamless collaboration between City Concepts, Box3, TP Bennett, and Forza. We deeply value these partnerships and the trust placed in our ability to tackle complex challenges and deliver exceptional results for prestigious clients.

This project perfectly encapsulates what City Concepts stands for: industry-leading acoustic solutions, innovative design, meticulous attention to detail, a commitment to British manufacturing, and a collaborative spirit that turns challenges into triumphs. The Cleveland House installation is more than just a workspace; it’s a demonstration of how acoustic excellence and aesthetic harmony can coexist, creating an environment that is both inspiring and highly functional – essential qualities for a space where investment strategies and financial decisions of global significance are made.
We are incredibly proud of this achievement and look forward to many more successful collaborations with our valued partners, continuing to sculpt tomorrow’s workspaces, today.
