Glass links & glass box roofs in Heswall: what is involved?
For Heswall 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Heswall, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Heswall is around 12 km from Liverpool, and we survey and fit throughout that part of Merseyside, including the CH60 district.
Specification options
- Concealed gutters and drainage
- Structural glass beams and fins
- Solar-control and low-iron glass
- Frameless or slim-framed glass
- Heated glass on some systems
- Keeps period walls on show
- Can include frameless doors
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 Heswall
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.
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. 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.
Read the planning permission guide before you commit to a design.

Questions about glass links & glass box roofs in Heswall
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
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.
Will I need planning permission in Heswall?
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 Heswall free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
