Choosing square roof lanterns in Derbyshire
Four triangular panes meeting at a point: a pyramid lantern for square openings.
Across Derbyshire, the shortest day brings around 7h 33m of daylight and the midsummer sun reaches about 60.4° at noon. A lantern collects light from the bright overhead sky all year, and the right glass keeps the long summer days comfortable.
- Stock colours or any RAL on request
- No ridge, a neat apex cap instead
- Four triangular panes to a single apex

Planning and building regulations in Derbyshire
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations 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.

Square roof lanterns in Derbyshire: questions
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.
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.
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.
Who checks building regulations for a lantern in Derbyshire?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
