Questions from Swanley
Should the lantern match my bifold doors?
A common choice is to match the outside colour, often anthracite. The inside can be white to keep the ceiling bright.
What is the difference between an orangery and a conservatory?
A conservatory has a mostly glazed roof; an orangery has a mostly solid roof with a lantern in the middle and usually more solid wall. Orangeries are easier to keep comfortable year round.
Who checks building regulations for a lantern in Swanley?
