Rectangular roof lanterns for Southampton homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 62.5° high over Southampton, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Intermediate rafters added on longer lengths
- Suits kitchen-diners and rear extensions
- Ridge along the long axis, four glazed slopes

Planning and building regulations for Southampton
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Southampton 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 Southampton
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
What is the most common rectangular roof lantern size?
Sizes of 1000 × 2000 mm and 1500 × 2500 mm are common standard sizes for kitchen and dining extensions, but the right size is the one that matches your kerb. If your kerb is not built yet, our sizes guide helps you pick a standard size first.
Can you fit a roof lantern in Southampton?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Southampton?
With the midsummer sun about 62.5° high at noon, roof glass in Southampton gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
