Glass links & glass box roofs in Falmouth: what is involved?
For Falmouth 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.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. In Falmouth, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Jobs in Falmouth 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.

- Concealed gutters and drainage
- Solar-control and low-iron glass

Planning and building rules for Falmouth
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. 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.
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.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Falmouth: questions
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.
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.
Do I need to be at home for the survey in Falmouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Falmouth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
