Hey there Anthony, what did you end up doing with this space? Bit of a tricky space!

I would leave the render colour and just tile a trim around the base in a pattern and over the arch of the brick. But I also recalled the pizza oven at a pizza place where I grew up. They make great pizza, but the oven is so cool! You could do something like this!

Look at 'Iron Ash'. Its a treated version of what you're after. Don't know anything about it but seen it recently on the web. Overall avoid Merbau as mentioned above, as well as being an imported 'sustainably' managed timber.... Use local product's when available as they're manufacturered to high standard's, supporting local job's, companies must meet tight regulation's, etc. unlike other countries....

Daniel Lindahl - I didn't say to get rid of it - I just said to change it for something else - I have a 70's home owner built - cavity brick - Daniel sometimes it is working with what you have in order to keep costs down - paintings - if you have several - can be changed around your home for a interesting look - as our homes are our homes - the paintings - can always be shared in various rooms/walls to suit ones mood.
