Around Diss and the wider county, housing stock runs to flint cottages, barn conversions and big-sky rural plots — lanterns suit both contemporary builds and conservation-sensitive conversions. We've specified and supplied for exactly these property types across Norfolk, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Diss, Aylsham, Holt and Norwich and the rest of Norfolk all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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 — supply-only Korniche orders are dispatched UK-wide with assembly instructions, and our team is on the phone if your builder has questions on the day.
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 — Diss is inside our standard Norfolk coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Diss on dedicated glass transport.
Stocked standard sizes typically deliver to Diss 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.
