Questions from Castlereagh
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.
Is it worth having solar-control glass in Castlereagh?
With the midsummer sun about 58.9° high at noon, roof glass in Castlereagh gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Castlereagh?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district council before ordering.
