Rectangular roof lanterns for Oxford homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 61.7° high over Oxford, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Ridge along the long axis, four glazed slopes
- The most size options of any lantern shape
- Suits kitchen-diners and rear extensions

Planning and building regulations for Oxford
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 Oxford 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 Oxford
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
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.
How quickly can I get a roof lantern in Oxford?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for OX1.
Is it worth having solar-control glass in Oxford?
With the midsummer sun about 61.7° high at noon, roof glass in Oxford gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
