The county's housing stock — stone farmhouses and border-town terraces where heritage detailing is frequently requested — shapes our recommendations here more than any brochure could.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

Yes — we'll send comparative section drawings showing our slimline profile against a standard lantern at the same scale, so the difference is concrete before you commit.
On current systems, around 40mm at the ridge externally. Claims much below that usually measure a different part of the frame — we'll always quote like-for-like ridge and hip dimensions so you can compare honestly.
No — the slimness comes from structural bonding and better alloys, not thinner-for-the-sake-of-it metal. Each lantern is engineered for its span and site wind loading.
Tighter tolerances, structural glazing and higher-spec profiles all add manufacturing cost, and installation needs more care. It's the premium tier of the lantern market and priced accordingly.
