Gable fronted conservatory orangery conversion cost
A orangery conversion on a medium Gable fronted conservatory typically costs £14,000 to £35,000, fitted.
A gable fronted conservatory has an upright triangular front instead of a sloping one, so the roof runs back to the house like a small pitched house roof. It gives the most headroom and light of any style.
Orangery conversions on a Gable fronted conservatory
Gables are less often converted to orangeries because the upright front does not suit a lantern layout.
- The triangular gable end is usually glazed. With a tiled roof it can stay glazed, be clad, or be filled with an insulated panel.
- The pitched roof suits tiles well and looks like a proper extension from the garden.
- Higher ridge heights can mean scaffolding rather than ladders, which adds cost.
