Planning and building regulations in Dumfries and Galloway
Here the Building (Scotland) Regulations and the domestic Technical Handbook set the standards, with a building warrant usually required for extension work.
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 Dumfries and Galloway: questions
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.
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.
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.
How quickly can I get a roof lantern in Dumfries and Galloway?
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 Dumfries and Galloway.
