Technical Details

Specification and Options

Product fit

A raised lantern for square openings

A pyramid lantern is the cleaner raised form when the roof opening is square. The shape rises evenly to a central point, so it can look more balanced than forcing a rectangular hipped lantern onto the wrong opening.

Best fit for

  • Square flat roof openings where symmetry matters
  • Rooms needing a raised roof feature without a long rectangular form
  • Projects where the lantern is visible from inside and outside

Consider another option when

  • The opening is long and rectangular rather than square
  • The roof glazing should stay flat and low profile
  • Ventilation or a walkable roof area is the main requirement

What we check on survey

  • We check whether the opening is genuinely square enough for the pyramid form.
  • We confirm where the central point will sit in relation to the room below.
  • We discuss frame colour, glass tint, and vent options before manufacture.
