Are Timber frame orangeries worth building? Here’s what to know

Timber frame orangeries are an excellent choice if you require the light and spacious feeling of a conservatory, but want the warmth and solid structure of a brick extension.  

What is a timber frame orangery?  

A timber orangery consists of timber window frames, doors at the sides, and sometimes separate timber glazed roof lanterns built-in.  Some experts like to use the 75% rule. If the extension has less than 75% glass it is classed as an orangery rather than a conservatory. Orangeries tend to have a brick base or more brickwork than a conservatory.  

Do you need planning permission for an orangery?  

An orangery can be seen as halfway between a conservatory and an extension. It’s an extended space that has the insulation of brick walls but the benefit of lots of light and good views.  

For planning purposes, an orangery is considered a single-story extension on and has the same building regulations as an extension. However, you won’t need planning permission for an orangery if you build within permitted development.
