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!

hi there khiara, I know this is an old post but just wondering did you ever try turboheat and if you did how did you find it? thank you :)

Depending on your house style and how it would work with the 3 different measurements, you could look at doing a herringbone style pattern for example:

Our last house and our current house both had wood floors and lots of wood furniture. Using area rugs (I've got a weakness for oriental rugs) provides separation between the floors and the furniture. And if the walls are light, as in LesleyH's photo above, you will certainly not feel overwhelmed with wood. The only time there's an issue in my mind is when the walls are also wood clad - that can be a bit confronting and needs management.
