Glass links & glass box roofs for Hitchin: the essentials
Glass links & glass box roofs in Hitchin means frameless glass links joining old and new buildings. We cover the SG4 district and the rest of Hertfordshire, with a survey before any price is fixed.
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.
Jobs in Hitchin 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.

Do you need permission in Hitchin?
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
Read the planning permission guide before you commit to a design.

Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
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.

Can you work alongside my builder in Hitchin?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
