What do glass links & glass box roofs in Sandown involve?
Thinking about glass links & glass box roofs in Sandown? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Sandown, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
From Sandown to Shanklin, Ryde and Newport, Isle of Wight, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Sandown
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. 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.
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.

Common questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
Is the survey in Sandown free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Sandown?
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.
