Glass links & glass box roofs for St Helens: the essentials
For St Helens 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
We work across Merseyside, including St Helens, and in neighbouring towns such as Prescot and Ashton-in-Makerfield. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in St Helens
- Structural glass beams and fins
- Solar-control and low-iron glass
- Frameless sliding or pivot doors
- Concealed gutters and drainage
- Heated glass on some systems
- Can include frameless doors
- Bright circulation space
What to check first
- Thermal performance of large glass areas must be calculated
- Abutments with old masonry need careful weathering
Do you need permission in St Helens?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about glass links & glass box roofs in St Helens
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
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.
Will I need planning permission in St Helens?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
Is the survey in St Helens free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
