Roof Lanterns in Cranleigh
Roof lanterns are transforming kitchen extensions on the listed and heritage buildings in Cranleigh across the GU6 postcode. Where a flat-roof rear extension would once have been a dark space, a Korniche roof lantern fills it with natural light from above, making the kitchen-diner feel substantially larger and brighter. The patented snap-fit aluminium frame installs in hours rather than days, and the slim 40mm rafter holds 30% more glass than older lantern designs. Standard and bespoke sizes are available up to 6m x 4m. We install roof lanterns across Cranleigh and the surrounding areas including Guildford and Godalming, often as part of a combined project with bifold or sliding doors.
