334 Oxford Street

At 334 Oxford Street, a prominent mixed-use development in central London, RYNO was appointed to design and supply a fully engineered roof terrace paving solution capable of withstanding significant wind uplift forces, while maintaining the clean, refined architectural vision set by Allford Hall Monaghan Morris (AHMM).

Working closely with Tilbury Contracts, Bovis (Main Contractor), and the wider consultant team, RYNO delivered a bespoke Smart Rail paving system incorporating a concealed wind uplift restraint - ensuring performance, compliance, and aesthetic integrity on a highly exposed urban roof terrace.

The Challenge

Located on Oxford Street, the roof terraces at this development are subject to exceptionally high wind loads due to their elevation, exposure, and surrounding urban wind tunnelling effects.

Early-stage wind uplift assessments identified forces that exceeded standard terrace paving solutions. The challenge was to:

• • Mitigate significant wind uplift without introducing visually intrusive fixings
  • Maintain AHMM’s architectural intent, particularly across curved tile layouts
  • Coordinate complex interfaces across waterproofing, insulation, and structural build-ups
  • Ensure safe installation and temporary material storage during construction

In addition, the project required detailed coordination around davit arm sockets, access zones, and service penetrations, all while keeping the system demountable for future maintenance.

The Solution

RYNO developed a fully coordinated TerraSmart Rail Paving System, utilising:

• • TerraSmart Rail Paving: Lattice Frame
  • TerraSmart Rail Paving: Hidden Wind Uplift Restraint
  • Tocco Concrete porcelain pavers in Clay Taupe

The system was engineered specifically for the project following detailed wind uplift analysis and structural calculations.

Key system features included:

• • Hidden Wind Uplift Restraint
  • A discreet stainless steel fixing integrated into the kerf of the porcelain tiles and mechanically secured to the RST aluminium support rail. This concealed approach provided robust wind resistance while preserving a seamless surface finish.
  • Architecturally clean detailing
  • All fixings remain invisible in the completed installation, allowing the curved tile geometry and materiality to take visual priority, a key requirement for AHMM.
  • Demountable and maintainable design
  • The retained washer system allows individual tiles to be removed and replaced if damaged, without disturbing surrounding finishes.
  • Structural assurance and load verification
  • RYNO undertook full structural calculations across the terrace build-up, including localised strengthening around davit arm socket locations to meet loading requirements and long-term performance expectations.
  • Compatibility with the full roof build-up
  • Load transfer through the pedestal and rail system was carefully reviewed to ensure compatibility with the waterproofing, insulation, and substrate layers beneath.

Collaboration & Technical Support

RYNO worked in close partnership with Tilbury Contracts, our long-standing installation partner, providing:

• • Early-stage design support and terrace layout development
  • Detailed wind uplift assessments and bespoke mitigation strategy
  • Regular design workshops and site coordination meetings with AHMM
  • On-site technical support during installation to address queries and sequencing

During construction, concerns were raised around temporary storage of materials on the exposed roof terraces. RYNO collaborated with structural engineers to assess risk and provide assurance on safe working practices, ensuring materials remained secure throughout the installation phase.

A key aspect of coordination involved agreeing demarcation studs and interfaces for outlets, access points, and maintenance zones - allowing clean transitions between trades and reducing on-site clashes.

The Result

The completed roof terrace at 334 Oxford Street delivers a wind-resilient, fully engineered paving solution that meets stringent structural and safety requirements without compromising architectural intent.

Through early technical involvement, close collaboration, and bespoke system design, RYNO helped the project team confidently deliver a high-performance terrace solution suited to one of London’s most demanding urban environments.
