Crafting roof terraces with in-house expertise Jamie Faulker, Innovations Manager, Raaft

February 2026

At Raaft, every component of our complete terrace system is manufactured in-house at our facility in Sussex. This level of control gives us a huge advantage when it comes to quality, performance, and finish. But what does it really mean in practice and why does an in-house approach matter so much for customers and the wider roof terrace market?

A big part of the answer lies in how close our teams work together. Having engineering, design, innovation and manufacturing all under one roof creates a level of communication and efficiency that simply isn’t possible when elements are outsourced. It is much quicker and easier to develop solutions to any challenges, ensure quality standards are maintained and helps us stay true to the original vision for every product within our roof terrace system.

Concept to component

Most new ideas begin with a concept or a need we have identified within the market. From there we move through a structured but creative journey. We start with qualitative testing, where we speak to customers and installers to understand the issue from all angles, before we carry out quantitative testing to define what really matters in performance terms.

Once we have this clarity, the design team starts to generate and brainstorm potential design solutions. Designs then progress through a series of more than 10 quality gateway tests and engineering evaluations. This covers everything from load capacity to durability. We prototype using our 3D printing capabilities, refine, test again using our own equipment and build toward final certification before a product is ready to launch.

This in-house design, testing and manufacturing process ensures this whole cycle is seamless and nothing gets slowed down by external suppliers or feedback loops. If a design requires a modification or adjustment, we can make the change, walk it over to manufacturing and assess it immediately.

Close collaboration enables faster innovation

The close proximity between the respective teams is particularly valuable for our screwless modular terrace system. Designers consider how components will be handled and installed on site, while engineers evaluate tolerances and long-term durability, and manufacturing advises on the smartest and most sustainable way to produce each respective part. The final result is a product that performs to the highest standard, offers design flexibility and fast installation. The complete system’s success is down to every decision being made collaboratively.

Ultimately, our in-house expertise provides us with the agility to move us forward as roof terrace experts, refine our modular terrace systems, and provide specifiers, installers and developers with exceptional roof terraces. When every part of the process is shaped internally by Raaft’s teams, what does that open up for the future of a roof terrace design?
