Roof Lanterns in Southampton & Hampshire
A roof lantern is a raised, multi-panel glazed roof structure fitted into a flat-roof extension, drawing natural light down into the room from directly above, not just from the sides. They’ve become one of the most popular additions to kitchen and living space extensions across Southampton and Hampshire.
Our roof lanterns are built on Sheerline’s glazed roof systems, with slim aluminium framing and independently verified thermal performance so the room stays comfortable year-round.
