Glass links & glass box roofs in Gravesend: what is involved?
Our glass links & glass box roofs service in Gravesend covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
From Gravesend to Grays, Strood and South Ockendon, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Gravesend?
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Is the survey in Gravesend free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Gravesend?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
