I like the top right picture where the grey floor tile appears to run up the wall. But the floor tile looks lighter than the wall, is it a different tile? I would pick a lighter shade from the Kalala Shan as the 2nd tile. Does the tile shop have a contrasting colour from the same family of tiles? Not sure I would go 2 different textures, unless one was really flat and non descript to contrast with textured one that would be the stand out feature. Great colour choices though. And would look lovely coming off the spotted gum floors too!

The façade cost will depend upon the materials you pick and site specs (sloping blocks are a bit more challenging) and labour costs ( just make sure that you check your trades licenses, insurances and references for everyone who works on your house) - once you're structurally sound then the rest is straight forward (it's also been my experience with my builders - who are awesome - that they can come up with some amazing ideas that are cost effective and have a real wow factor). If it were me I'd ask around the neighbourhood for builders that can be recommended - they should be able to do it all at the same time and save you some money. On the materials - I'd be tempted to go with natural timber that will weather naturally without needing maintenance - personally I'd lean towards a Japanese technique of charring the timber so that you don't need to do a lot of upkeep - called Shou-sugi-ban - the reason being that the dark colour will tone in with your window frames.

Love your house and especially white houses, I guess if you live on a busy road or dusty climate it will show more dirt, along with that which comes from rain, you'll just have to think of it as more windows to clean. A good hose down with something that paint pro's would suggest every now and then would take care of any staining. Some of my favourites The most famous, just shows that white houses have been around for a very long time, ageless cheers

Hi Matthew we bought an old doer upper that needs refreshing so I was keen to follow your post. We so far painted the front door replaced front letterbox guerney washed the concrete drive and have bought a panel lift door for the carport. We removed all the overgrown trees. Maybe guerney wash your roof , driveway and front steps, thats our next job (roof) and start with the gardens. If you keep the awnings - spraypaint them in a single tone, paint or replace the driveway fence, Remove that tall shrub or trim it, plant a row of plants up along the drive. Great house, like ours you can only improve it in value. Enjoy renovating!
