Call 020 8916 2222The former helideck at Harrods has been reimagined as a luxury rooftop event space with panoramic views across London’s skyline. Positioned above one of the world’s most recognisable retail landmarks, the new terrace needed to respect the heritage of the building while integrating seamlessly with a newly constructed internal pavilion.
The architect specified a fully compliant, Class A fire-rated decking solution capable of meeting stringent fire regulations without compromising on aesthetic quality. Wallbarn was appointed to provide the complete Class A fire-rated substructure, working in partnership with Fire Deck, who supplied Exadeck porcelain decking boards.

A High-Profile Collaboration
This prestigious rooftop redevelopment brought together leading expertise at every level:
- Harrods as client
- Kendall Kingscott Ltd as architect
- TC&D Construction as specialist contractor
Wallbarn and Fire Deck worked closely with the contractor from the early planning stages, providing:
- Layout options and design input
- Technical guidance on build-ups and fire compliance
- Site visits and hands-on support
- Coordinated delivery scheduling
This collaborative approach ensured the system met:
- Regulatory requirements
- Structural performance standards
- High-end aesthetic expectations
All while staying on programme for Harrods’ first rooftop event in May 2025.
Overcoming Complex Rooftop Challenges
The helideck presented several significant technical challenges, including:
- Varying floor heights of up to 400mm
- Seamless transitions between interior and exterior spaces
- Multiple complex access points
- Tight installation deadlines
To address these issues, a highly adaptable system was required—one capable of maintaining stability, compliance and precision across a complex rooftop layout.
Engineering the Class A Substructure
To overcome these challenges, Wallbarn supplied a fully integrated Class A system built around:
Key benefits of this approach included:
- Adjustable support for varying height thresholds
- Secure fixing directly to the structural deck
- Compatibility with non-combustible materials
The pedestals provided a stable, adjustable base, while the aluminium joists created a rigid and perfectly level framework. This was particularly important in areas where:
- Ramped sections were required
- Rails needed precise angle cutting
- Cross-fixing was necessary for structural rigidity
Using 60mm-wide aluminium joists ensured:
- Consistent support across the terrace
- Flat, even installation planes
- Enhanced structural integrity
Systems such as the I-Plus aluminium beam framework are specifically designed to deliver this level of precision in demanding rooftop environments.
Once the framework was complete, Exadeck boards were installed using the Class A W Clip fixing system, delivering a secure and non-combustible finish.
Precision in a Demanding Layout
The design team selected a stacked bond layout—a visually striking configuration that demands exceptional accuracy.
To achieve this, each Exadeck board underwent a double-rectification process:
- Rectified on the side planes
- Rectified on the underside planes
This ensured:
- Perfect dimensional consistency
- Elimination of movement or rocking
- Crisp alignment across the entire terrace
When combined with the precision of the Wallbarn I-Plus substructure system and the stability of MetalPad Ex pedestals, installation was significantly more efficient than many traditional systems.
The result is a series of clean, uninterrupted lines that enhance the overall sense of luxury.
Aesthetic Warmth with Structural Strength
While fire compliance and structural integrity were essential, the visual finish was equally important.
Exadeck’s wood-effect porcelain boards provided:
- A warm, natural aesthetic
- Compatibility with historic architecture
- Seamless integration with modern structures
With 17 different surface patterns, the boards deliver:
- Realistic wood grain detailing
- Visual depth and variation
- A premium finish suitable for luxury environments
At the same time, the system offers:
- Superior scratch resistance
- High stain resistance
- Exceptional durability under heavy foot traffic
- Minimal maintenance requirements
Built for Performance and Experience
Beyond aesthetics, performance in all conditions was critical. The completed system is:
- Fully Class A fire-rated
- Structurally robust
- Weather-resistant
- Quiet under rainfall
- Stable across varied build-up heights
The integration of systems such as:
ensures long-term performance without compromising on design.
The terrace also provides:
- Seamless indoor-outdoor transitions
- Consistent surface levels
- A durable platform for high footfall
A Landmark Rooftop Achievement
Transforming a former helideck into a refined rooftop event destination required:
- Careful planning
- Advanced engineering
- Close collaboration across all teams
Through the integration of Wallbarn’s Class A fire-rated systems and Exadeck porcelain decking, the project team delivered:
- Full compliance with fire regulations
- A flawless, high-end finish
- A durable and future-proof outdoor space
The new rooftop offers panoramic views across London and provides Harrods with a resilient and elegant platform for high-profile events.
