Planning and building regulations in Forth Valley
Scottish building standards, including Section 6 on energy, apply here, and a building warrant is normally needed for extensions and structural alterations.
Your council will confirm whether your lantern is permitted development under Scotland's rules, particularly for listed buildings.
Building regulations are checked by your local authority building standards (verifier) service. Some like-for-like replacement work does not need a building warrant but must still meet the building standards. Your council's building standards service can confirm.

Rectangular roof lanterns in Forth Valley: questions
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
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.
How quickly can I get a roof lantern in Forth Valley?
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 Forth Valley.
