Square roof lanterns for Chelsea homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 62.0° high over Chelsea, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Strong central focal point from below
- Four triangular panes to a single apex
- Square sizes from about one metre

Planning and building regulations for Chelsea
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Chelsea are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Chelsea
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
