Lantern or flat rooflight for the kitchen we are adding at the back?
When a brick house on the plain gets a kitchen or dining extension, the new flat roof is the obvious place for light. The question is which shape of rooflight belongs on it, and the answer starts with the room, not the glass.
A wide room or a narrow one
A lantern is a glazed box that stands up from the roof. It lifts the ceiling, spreads light in the middle of a wide room and suits a dining table underneath. A flat rooflight lies close to its upstand. It suits a narrower kitchen, looks calm from the garden and is the simpler of the two to look after. Either one can be fixed or can open, and an electric one raises from a wall switch.
Looking after the outside
The outside glass of a flat rooflight is reached with a long-handled brush from the garden or a ladder. A lantern has several panes and bars, so it takes longer. Some makers sell glass with a coating meant to shed dirt, which cuts the washing but does not end it. We cover this before you order.
Sun and blinds
A room that faces the afternoon sun can warm up. A pleated blind inside, or solar control glass chosen at the start, keeps it usable. Our page on solar control glass explains what it does.
Planning
Whether a lantern on a new kitchen extension needs an application is set out in the planning guide, and Cheshire East Council is asked about your address. Our guide to lantern sizes and kerbs goes into the sizes.
