Roof lanterns for kitchen extensions: what to plan early
Roof lanterns can transform a kitchen extension, but sizes, glass, ventilation, kerb details, colour, and access need planning before order.
Light is only one part of the decision
A roof lantern can make a kitchen, dining space, or extension feel brighter and taller. The size and position should work with the room layout, island, roof structure, lighting, and how much direct sun the space receives.
Glass specification affects comfort
Solar control, thermal performance, self-cleaning coatings, toughened or laminated glass, and opening vents can all change how the room feels through the year. It is worth discussing glass before finalising the opening.
Kerb and access details need coordination
Lanterns rely on accurate upstand sizes, waterproofing, site access, lifting, and installation sequencing. Builders, roofers, and glazing teams should agree the details before the lantern is manufactured.
Quick checklist
What to confirm before you order.
Every property and opening is different, so use this as a starting point before a measured survey and final specification.
- Plan lantern size around room use and roof structure
- Discuss solar control, thermal glass, and ventilation early
- Confirm kerb sizes and waterproofing responsibility
- Check lifting access, delivery, and installation timing
