Ideas for best solution to replace these doors!

[Jasonnaylor]

Morning everyone,

 

So I am renovating a house I purchased that was in a bad state. The main house has been renovated by a builder, now looking to tart up the adjoining brick outbuilding myself

 

What would be the best solution for these two old external doors? 

 

I've checked with local building control and Im ok to install anything new without having them inspected so that's one bonus

Composite doors are low maintenance and look a bit better than upvc
