RIBA Stage 3 Support

At FX Glass, we know that RIBA Stage 3 is where key design and specification decisions begin to take shape.

This is a critical stage in the process, where architectural intent is being developed into coordinated, buildable design, and where glazing systems, performance requirements and material selections all need to align.

We understand the pressure this brings. Balancing aesthetics, compliance, coordination and programme is rarely straightforward, particularly when multiple specialist systems are involved.

So how can FX Glass support your team at Stage 3?

We work alongside architects & designers to support the development of glazing packages as designs progress.

Our Stage 3 support typically includes
✔ Technical design consultations
✔ Design intent drawings to support coordination
✔ Specification writing assistance
✔ Guidance on system selection and performance requirements
✔ Material and finish samples
✔ Input on acoustic and fire performance compliance
✔ Coordination with wider project teams where required

The aim is to remove friction from the process, giving you the technical clarity and information you need to focus on delivering strong design outcomes.

Early engagement at Stage 3 can help reduce risk, limit late stage coordination issues and support a smoother transition from design to construction.

If you would like support at Stage 3, speak to the FX Glass team about how we can work with you as your designs develop.
