Square roof lanterns for Coulsdon homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 62.1° high over Coulsdon, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.

Planning and building regulations for Coulsdon
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 in Coulsdon 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.
