Gable-front conservatories
A gable-front conservatory has a tall triangular front, with the roof ridge running straight out from the house. It looks grander than a lean-to and lets in a lot of light, and the high front suits larger gardens and bigger houses.

What moves the price of gable-front conservatories
- Size
Floor area is the biggest single driver. A larger footprint means more frame, more glass and a bigger base, though the price per square metre falls as the conservatory grows.
- Roof
Polycarbonate is the cheapest roof, glass costs more and a solid tiled roof costs the most. The roof is often the biggest difference between two quotes for the same shape.
- Frame material
uPVC is the base price. Aluminium and hardwood both cost more, and hardwood costs the most.
- The site
Sloping ground, poor soil, drains in the way and awkward access all push the price up before any frame goes in.
- Who builds it
National brands usually quote well above local FENSA or CERTASS installers for a similar specification. Compare like for like on frame, roof, base and guarantee.

Common questions about gable-front conservatories
Is a gable-front conservatory more expensive than a Victorian?
Usually, at the larger sizes it is built at. The taller front and the extra frame and glass add cost.
Does a gable-front conservatory get too hot?
The tall glazed front can, in a south-facing garden. Solar control glass and blinds deal with most of it.
Do I need planning permission for a gable-front conservatory?
Many are permitted development, but the height of the ridge is one of the limits. Check the rules for your property before you order.
