An orangerie is a style of conservatory that typically incorporates a glass lantern skylight set within a solid roof.

The sides of the roof often have elements of solid wall incorporated into the design. The combination of both these components creates a light and airy room which can also provide elements of shade against the heat and glare of the sun.

If you are not looking for an all glass room, this is a very traditional approach that will fit in well with historical and modern properties alike.
