Glass links & glass box roofs in Alnwick: what is involved?
For Alnwick homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
Jobs in Alnwick are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Heated glass on some systems
- Concealed gutters and drainage
- Frameless or slim-framed glass
- Frameless sliding or pivot doors
- Solar-control and low-iron glass

- Designed around the existing building
Before you order: points to check
- Structural calculations are part of the design
- Thermal performance of large glass areas must be calculated
Planning and building rules for Alnwick
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Glass links & glass box roofs in Alnwick: questions
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Can you work alongside my builder in Alnwick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Alnwick free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
