Norfolk property here means flint cottages, barn conversions and big-sky rural plots — lanterns suit both contemporary builds and conservation-sensitive conversions. That local context shapes what we recommend in Norwich — from glass specification to frame colour — before a single quote is written.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
From Norwich we also serve Fakenham, Aylsham and Holt and the wider county — so if you're comparing quotes anywhere in Norfolk, ours is free, fast and without obligation.
The joint engineering. Korniche components machine together so precisely that the lantern assembles without silicone, external clips or cover caps — which is why installers love it and why the finished lines look so clean.
The frame itself can be assembled on the kerb in under 30 minutes by a competent installer; a full fit including glazing and flashing is comfortably a one-day job. Manufacture lead time is typically one to two weeks.
Yes — the system is fully thermally broken with no metal-to-metal path from outside to inside, and paired with argon-filled units it achieves U-values that comfortably satisfy Building Regulations for extensions.
Every Korniche is made to order, so 'custom' is the standard. You give us the external kerb size and the lantern arrives fabricated to those exact dimensions.
Yes — Norwich is inside our standard Norfolk coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Norwich on dedicated glass transport.
Stocked standard sizes typically deliver to Norwich within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
