Modern orangery with anthracite frames and glazed lantern on a brick home

Modern & traditional orangeries

The elegance of glass, the comfort of a room.

Perimeter-roofed orangeries with a central lantern — classical proportion or crisp modern lines, both engineered for year-round living.

Good questions

Frequently asked

What is the difference between an orangery and a conservatory?+

An orangery has a solid, insulated perimeter roof with a central glazed lantern, so it performs like a room of the house.

Is an orangery usable in winter?+

Yes. Insulated walls and roof, thermally broken frames and integrated heating hold temperature year-round.

Do orangeries need planning permission?+

Often not, but we confirm at design stage and submit any application required within your fixed price.
