How much does a Maxi-Pyramid roof lantern cost?

As a guide, a Maxi-Pyramid roof lantern starts from £1,599 for the 500 x 500mm guide size and £3,699 for the 2500 x 2500mm guide size. The final quote depends on measured square opening size, kerb detail, colour, glazing, vent controls, access, and site conditions.

Why use a pyramid lantern on a square opening?

The four-sided form rises evenly from each side, so it usually looks more balanced over a square opening than a hipped lantern designed for a rectangle.

Can a pyramid lantern include an opening vent?

Vent options can be discussed, but suitability depends on the final size, roof access, wiring route, and the room below. We confirm this during survey.

What is the Maxi-Pyramid lantern best suited for?

It is designed specifically for square flat roof openings. The symmetrical four-sided form responds naturally to a square opening where a standard hipped lantern would look unbalanced.

Is the Maxi-Pyramid available in custom colours?

Yes. Custom RAL exterior colours and interior colour packs are available, alongside the five standard stocked colours. We confirm the colour at quote stage.

Can I add a vent to a pyramid lantern?

Yes. Manual, electric, and thermostatically controlled vent options are available. We confirm suitability and placement during the survey visit.

When does a pyramid lantern look better than a hipped lantern?

A pyramid lantern usually looks cleaner over a square opening because all four sides rise evenly to the centre. A hipped lantern suits longer rectangular openings better.

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.
