All about our Team

In April 2025, we proudly opened the doors to our inspiring new showroom — The Cowshed, located just outside Stirling in Central Scotland.

Glass Worx Ltd was founded by Mark and Steff, who bring over 30 years of combined experience in the fields of architecture, passive house design, and high-performance glazing. Well-respected within the architectural glazing industry, their shared passion for precision, performance, and design led to the creation of a company built on trust, expertise, and innovation.

At Glass Worx, glazing isn’t just a product — it’s a key element in creating beautiful, energy-efficient spaces. Our mission is to provide architects, homeowners, and builders with access to premium glazing solutions from industry-leading brands like Internorm, Dako, and Qfort.

Whether you’re designing a passive house, modern extension, or a full architectural build, we’re here to help bring your vision to life with expert advice, tailored service, and the highest quality systems.

Design is our first priority

Glass Worx limited was established in 2024 by Mark McLean and Steff Bell. We offer Architectural Glazing products through a design-led approach to selecting the products and systems that are best suited for your building and or development.

Experienced leadership team

Mark and Steff have worked on projects together from 2011, and laterally headed up the senior management team at Scotia Architectural Systems. Backed by Europe's leading glazing manufacturers: Internorm, DAKO and Cortizo, we established GLASSWORX to use our construction and design experience to get best performance and aesthetics based on your budget.
