Questions from Trowbridge
Will I see a drawing before it is made?
For made-to-measure and special shapes, yes: the order is based on a drawing you approve, so the size you check is the size that gets made.
Do bespoke lanterns cost much more?
For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.
Can you fit a roof lantern in Trowbridge?
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.
Do I need planning permission for a roof lantern in Trowbridge?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
