A FULLY MANAGED SERVICE — FROM STRUCTURE TO GLASS
Building & Extension Services — Expert Integration with Glazing
At The Fenestration Network, we provide a comprehensive, end-to-end service that brings every stage of your project together under one expert team. From foundations and brickwork to glazing and finishing, we seamlessly coordinate every trade to guarantee precision, performance, and a smooth experience for you.
We don’t just install glazing — we build around it.
Our integrated approach means the structural and glazing elements are designed and executed to complement one another from the start, delivering:
- Perfect junctions between structure and glass (no leaks, no cold bridges)
- Cohesive design and performance across the entire build
- Faster project delivery with a single accountable team
- Consistent quality control from groundworks to final finish
This joined-up delivery model ensures your orangery, extension, or renovation achieves the best of both worlds: robust construction and high-performance glazing, all delivered by specialists who understand both disciplines.

OUR BUILDING AND EXTENSION SERVICES
What We Offer:
Below is a breakdown of the services we provide under this building / extension offering:
1. Home Extensions & Room Additions
We design and build full structural extensions — rear extensions, side extensions, attic/loft conversions — integrated with your existing glazing and building envelope.
2. Orangery Extensions & Glazed Rooms
Classic or contemporary orangeries, with bespoke roof lanterns, brickwork, glazed walls, and structural elements. We handle the entire build while maintaining high performance glazing.
3. Glazing-Adjacent Building Work
All building tasks around windows, doors, and glazing systems: structural sills, support lintels, infill walls, thresholds, weatherproofing, and finishing trades.
4. Structural Alterations & Renovations
Removing load-bearing walls, reconfiguring layouts, installing beams/columns, and ensuring all work dovetails with your glazing needs.
5. Full Project Management & Turnkey Delivery
We coordinate all trades (groundworks, structural, carpentry, roofing, glass, M&E) from start to finish. You receive a complete, ready-to-use space with no need to hire multiple contractors.
