Questions from Portsmouth
Will a traditional lantern need planning permission?
The style does not change the planning position; size, height and location do. Listed buildings and conservation areas are the main cases where consent is more likely to be needed.
Can I have cresting without finials, or the other way round?
Usually yes. Ranges treat cresting and finials as options. Tell us what you want and the quote will list each item.
Do I need planning permission for a roof lantern in Portsmouth?
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.
Can you fit a roof lantern in Portsmouth?
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.
