Square roof lanterns
A square roof lantern, often called a pyramid lantern, has four triangular glass panes that meet at a single apex. It suits square openings over a dining table, a hallway or the middle of a room, and it gives a strong, symmetrical focal point from below.

In short: Four triangular panes meeting at a point: a pyramid lantern for square openings. Guide prices start from £1,095 including VAT, supply only.
Where does a pyramid lantern work best?
Square lanterns work wherever the space below is roughly square or where you want light centred over one feature: a table, an island or a stair well. In smaller rooms a 1000 × 1000 mm or 1200 × 1200 mm pyramid can transform a dark middle bay.
Because all four panes meet at the top, a pyramid has no ridge. The apex is usually finished with a small cap, and on larger sizes the panes are split by extra hip bars.
Square or rectangular?
If your opening is within about 10% of square, a pyramid usually looks better than a short rectangular lantern with a stubby ridge. If the opening is clearly longer one way, rectangular is the better buy.

Square roof lanterns: common questions
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.
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
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.
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
