Large£4,900£3,900 to £5,900

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.

New polycarbonate roofs on a Gable fronted conservatory

Polycarbonate works but the tall, sunny gable shape tends to overheat more than other styles.

  • 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.
