Mortimer Street – Safe and Compliant Balcony Remediation with AliDeck
Delivering a Long-Term Balcony Solution for PJ Harte
AliDeck partnered with PJ Harte to deliver the successful remediation of several balconies at Mortimer Street in central London, transforming them into safe, compliant, and visually appealing outdoor spaces. For this project, we supplied our Senior Ridged Aluminium Decking Boards in Textured Sand, alongside our Eco 30 Joists and Adjustable Wind-Up Pedestals, providing a complete non-combustible system designed for performance and ease of installation.
This project required a durable, low-maintenance, fire-rated decking solution that would meet the latest building regulations without compromising on appearance or functionality. Through close collaboration, AliDeck supported PJ Harte in delivering a smooth and efficient installation, further strengthening the ongoing partnership between our teams.
A Complex Site with Curved Balconies – Made Easy with AliDeck
One of the defining features of the Mortimer Street development is its selection of curved balconies, which can often present unique installation challenges. Traditional decking materials can be difficult to work with on non-linear layouts, requiring extensive cutting and adaptation to fit complex shapes.
However, thanks to the versatility and intelligent design of the AliDeck system, these curved balcony areas were no obstacle. Our Senior Ridged Boards are designed to be easy to cut and install on-site, allowing installers to achieve a precise finish even on curved or unusually shaped platforms. This flexibility significantly reduced installation time and avoided unnecessary delays, ensuring the project remained on schedule and met all quality expectations.
The adjustability of our Wind-Up Pedestals further supported the installation process, providing fine-tuned height correction even on irregular surfaces. This helped to ensure a smooth, level finish across every balcony, regardless of shape or size.
Designed for Compliance, Built for Longevity
Following updates to UK fire safety legislation, all external elements on high-rise residential buildings must meet strict non-combustibility standards. The previous balcony surfaces at Mortimer Street no longer met these requirements, prompting the need for a full decking replacement.
AliDeck’s aluminium decking system offers a Class A2-s1, d0 fire rating, meaning it is fully compliant with BS EN 13501-1 standards and suitable for use on high-rise residential developments. Our Senior Ridged Boards not only provided the necessary fire performance but also offered a high level of slip resistance and a contemporary visual finish that complemented the building’s aesthetic.
All AliDeck products are powder-coated to a Qualicoat standard using Class 2 powder, delivering superior resistance to corrosion, UV fading, and general wear. This premium coating allows us to offer a 30-year warranty and a 60-year life expectancy, giving peace of mind to developers, property managers, and residents alike.
Working in Partnership with PJ Harte
AliDeck and PJ Harte have developed a strong working relationship over a series of successful projects, built on a shared commitment to quality, compliance, and efficiency. On the Mortimer Street project, this partnership was evident from the early planning stages, with our team offering hands-on support around product selection, technical advice, and logistical coordination.
Throughout the project, we remained closely involved, ensuring prompt delivery of materials and providing guidance where required to help PJ Harte’s installation team maximise efficiency and accuracy—particularly when working with the curved balconies.
Results That Last
With the balcony remediation work at Mortimer Street now complete, residents can enjoy safe, fire-compliant outdoor spaces that are built to last. The combination of AliDeck’s aluminium decking, Eco 30 Joists, and Adjustable Pedestals delivered a robust, long-term solution that meets today’s regulatory demands and tomorrow’s expectations.
Thanks to the ease of installation, even the more complex curved balconies were completed efficiently, with no compromise on quality. The result is a consistent, clean finish across the development that enhances both the safety and aesthetic appeal of the property.
