Square roof lanterns for Haverhill homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.

- Ideal over a table, island or hallway
- Four triangular panes to a single apex

Planning and building regulations for Haverhill
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Haverhill 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 Haverhill
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.
Do I need planning permission for a roof lantern in Haverhill?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Is it worth having solar-control glass in Haverhill?
With the midsummer sun about 61.4° high at noon, roof glass in Haverhill gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
