The single most common home for a roof lantern is the rear kitchen extension: a flat-roof addition across the back of the house, bifolds to the garden, island under the glass. We've supplied thousands of them.

This page covers the decisions that matter for kitchen projects — lantern size and position over the island, glass specification for cooking spaces, and coordinating with your builder's programme.
For kitchen extensions, position beats size. The lantern wants to sit over the social zone — usually the island or table — rather than dead-centre of the roof, and clear of the run where extraction ducting crosses the void. Sizing rule of thumb: the lantern's footprint at about one-fifth to one-quarter of the room delivers dramatic light without summer overheating. Glass matters more here than anywhere: kitchens generate heat and moisture, so we specify solar-control self-clean units as the default and add an opening pane where extraction is marginal. We slot fabrication into your builder's programme so the lantern arrives the week the kerb is ready.

Over the zone you'll actually occupy — the island or the dining table — not the geometric centre of the roof. We'll mark the position on your plan, checking it clears extraction ducting and any steels in the void.
A footprint around one-fifth to one-quarter of the room area is the sweet spot. For a common 4m × 6m extension that points to roughly 1500 × 3000 — dramatic light without turning summer lunchtimes tropical.
Solar-control self-clean units — the coating manages summer heat gain and the self-clean layer deals with the film cooking puts on overhead glass. It's our default spec for kitchen projects.
It needs to — ducting routes across the flat-roof void are the most common clash. Send the kitchen plan and we'll position the lantern and kerb clear of the duct run before anything is ordered.
Once the slab is in and dimensions are real. Fabrication then runs while walls go up, and the lantern lands the week your roofer has the kerb ready — no site storage, no programme gap.
