Renovating Conservatory

I have a small (3mtrs x 2.3mtrs) lean to conservatory at the back of my house, about 20yrs old which I am currently renovating. It has single brick parapet walls internally clad with painted timber which over the years has developed a black mould.

I will be adding air bricks to improve ventilation and replacing the cladding. I will use an anti-fungal paint but wondered if there was any advantage in using 25mm polystyrene insulation behind the cladding. The walls are pretty much damp free.

Any thoughts or advice please.

Yeah, knock it down and build a new one.

What are you looking to gain from this space?

A mould free, comfy warm place to while away the hours during the warmer months or an all year round habitable space?
Already thought of that. Quoted £6K!

Just use it for a bit of storage and a fridge, thought I might put in a couple of basic kitchen units to tidy things up a bit.

We have a reasonably well built conservatory, but only ever use it in the warmer months. The space is not heated and is rarely opened up into the main dwelling, so it remains cool but free of moisture.

As soon as you start to frequent a space that has not been designed with habitable usage in mind then you will inevitably end up disappointed.

These things require a lot of effort and cost in order to make them habitable, so tarting up a shack is not advisable.

An extension of that size would come in at about £7500 for the building work. Plus heating. Plus electrics.
