What We Offer

Services

With a portfolio spanning 60 years, we have successfully delivered envelope solutions across projects of every scale and complexity — from major infrastructure developments to asbestos refurbishments. Our experience demonstrates proven capability in the full cycle of design, engineering, fabrication, and installation.

We can take you every step of the way.

Our team de-risks delivery, safeguards programmes, and controls costs through precise design, quality-led installation, and strong supply chain integration. The result: durable, high-performance envelopes that meet technical, regulatory, and architectural demands.

Early Engagement

Detailed estimating aligned to aesthetics, programme, and budget. We provide technical, commercial, and methodology advice that helps architects, developers, and contractors make informed, risk-aware decisions.

Design

2D CAD and 3D BIM to deliver fully compliant drawings and details. Our design process ensures accuracy, buildability, and compliance with building regulations and performance requirements.

Fabrication

In-house manufacturing of glazing and metalwork, giving full control over quality, tolerances, and lead times — ensuring precision and reliability before arriving on site.

Installation

Delivered by our directly employed operatives and trusted subcontractors. We maintain the highest standards of safety, quality, and programme certainty throughout construction.

Maintenance

Planned and reactive maintenance services to extend the life of buildings. Our tailored maintenance contracts safeguard warranties, performance, and asset value over time.
