Who this guide is for
- Homeowners considering a glazed addition
- People comparing conservatory and orangery quotes
- Anyone budgeting a light-filled extension
- Readers weighing different roof and glazing choices
Glazing and frame
The extent and type of glazing, and the framing that holds it, are central cost drivers. Larger glazed areas and more substantial frames change the picture.
Glazing performance choices also affect comfort and cost.
Because the two terms describe a spectrum of builds rather than fixed products, two quotes labelled the same way can assume very different structures, so always check what each one actually includes.
- Glazed area and frame material
- Glazing performance options
- Doors and opening sections
- Solid versus glazed wall portions
Roof type
Conservatories and orangeries differ partly in roof: fully glazed, part-solid, or lantern-style roofs each carry different demands.
Roof choice affects light, comfort and the build.
Roof style, whether fully glazed, part-solid or lantern, shapes light, comfort and the build in equal measure, so it deserves as much attention as the glazed walls when you compare options.
Base and structure
A suitable base and any structural elements are key. Ground conditions, levels and how the structure meets the house all matter.
An orangery's more substantial walls differ from a lighter conservatory build.
Connection and finishing
How the addition joins the existing house, plus finishing such as flooring, heating provision and decoration, adds to scope.
Site access and waste handling also factor in.

Frequently asked questions
Questions readers ask about this topic
What drives conservatory and orangery cost?
Glazing extent, roof type and the base and structure are major drivers, along with how the addition joins the house. An orangery's more substantial build differs from a lighter conservatory.
Is an orangery more expensive than a conservatory?
They are different builds with different scopes, and this guide does not compare them in figures. Weigh the glazing, roof and structure each involves for your situation.
Why do quotes vary so much?
Quotes may assume different glazing, roofs, bases and connections to the house. Comparing them on a matched scope makes the differences easier to understand.
Does this give a price range?
No. It only explains the factors that affect cost. For figures specific to your project, gather itemised quotes from qualified professionals.
