A classically elegant home extension

All Firmseal Orangeries are individually Designed by our experts to perfectly suit your home in either uPVC or Aluminium.

An orangery is generally characterised by having a large lantern roof set into a flat roof with either pilasters or brick columns to all corners.

Often they feature either an ornate cornice to the guttering or can be built with brickwork all round with the flat roof set inside parapet walls. A Firmseal orangery-extension is a great addition to any home, when a conservatory really does become an extension to your home.

We have a range of enhancements and upgrades to help you customise your new favourite room.

Customise your living space from the inside to the outside.
