dislike both - unfortunately for me as we are now spending a large amount to have ours covered and painted :(

Great article posted yesterday on houzz for south facing walls interior and exterior essentially go warm greeny white eg whisper white not whites you suggest or grand piano quarter - beautiful

Look into terrazzo, it's basically polished concrete with style. Terrazzo is a poured coloured concrete with glass or stone chips in it to give it a variety of looks. It's then polished to a high lustre. It comes in any colour like from bright whites to black and you can choose the mix of aggregates to make your own custom flooring. Commonly seen in tiles, it can be poured as well to avoid the tiled look. A similar colouring to sandstone would be easy to achieve this way with a more durable finish. Terrazo's can also use interesting agregates like sea shells and limestone fossils to create a complete custom look. An alternative to a high thermal mass flooring would actually be the installation of phase change material mats in area's subject to direct light. Phase change material is a polymer used in the transport industry that either consumes or gives off heat as it moves from a solid to liquid state. The material is know to radiate either heat or cold back into the environment for many hours in a controlled release after several hours of charging through exposure to heat or cold. It's an inert technology that never wears out and innovative architects are beginning to incorporate it into passive housing design. The panels are manufactured to be quite thin so you could hang a pcm mat on a wall for example and easily cover it with something innocuous but it would passively heat the house.

Hey there, I love the terracotta! I would paint the house a white with a warm grey undertone to freshen it up but compliment the warmth too, a deeper neutral white will achieve this. I would paint the surround a deep chestnut brown to highlight your plantings - gutters same colour. Put in a caramel accent, perhaps with a timber door, planted caramel pots by the door. I would carry the white over your trim, to highlight the garden rather than the posts and hand rail. This might not be quite the colour scheme you mentioned, but if you surround the terracotta with a monochromatic look (especially with cold or stark undertones), those tiles will be all you see! Best to work with them to calm them down - In my opinion :)
