Hey Saml1992,
We did get the bradstone rendered, we went for K-Rend all over, including covering the existing render on the extension - and we couldnt be happier with the finish. We also decided to combine it with cement board cladding and it all came up a treat. I just took this photo (apologies its a bit gloomy here) so you can compare it to what it used to look like! The render and cement board has been up for 14 months now. (Still not finished the front steps though!)
