Converting Conservatory Dummy Door into Working Door

[Flipperflop]

Hello all,

Ive just joined the forum and looking for some advice.

Ive recently moved into a new property and it turns out that with the external conservatory french doors, according to the previous owner, only one door opens. The other is just a dummy door. This was a surprise as it appears to have normal hinges, has a lock barrel and appears just like a normal door but can not be opened.

My question is, would this take much work to convert into a fully functioning door?

Thank you in advance.

I hooe somebody can help.

Regards,
Graham.
