Glass Room or Orangery: Two Different Buildings
An orangery is a masonry building with a glazed roof lantern. A glass room is a light aluminium and glass structure over your terrace. They cost, build and feel entirely different.

Construction
Orangeries involve foundations, brick or block piers and internal plastering. Glass rooms sit on prepared bases with a fixed roof and sliding glass walls.
Disruption and time
Orangery projects run for weeks and involve trades in sequence. Glass rooms are typically installed within days.
Light and outlook
Glass rooms are far more transparent. Orangeries frame views through solid piers and feel like part of the house.
Thermal expectations
An orangery is designed to be heated as a room. A glass room is an outdoor room you can warm — usually with infrared — rather than a heated extension.
Frequently asked questions
Which needs building regulations approval?
An orangery normally does as a habitable extension. Glass rooms are frequently outside that, but always confirm with your local authority.
Can a glass room replace a tired conservatory?
Often yes, and it is a common reason customers call us.
Which is warmer in winter?
An orangery. A glass room is a shoulder-season and heated-comfort space.
Which suits a rented or leasehold property?
Glass rooms are lighter-touch and easier to agree, though consent is still needed.
