What is an Orangery?

An orangery is a premium glass extension that combines the light-filled qualities of a conservatory with the structural permanence of a traditional brick extension. Originally designed in 17th century grand estates for growing citrus fruits, modern orangeries feature a distinctive solid perimeter roof with a central glazed lantern.

At Room Outside, our bespoke orangeries are crafted to seamlessly integrate with your home’s architecture. Choose from timber, aluminium or hybrid frames, with optional brick or rendered pillars for a truly substantial feel.
