there are way too many colours going on here. Your home is a traditional style and yes the cream and green are traditional colours with the reddish brick however why did you put grey around the windows??also you have red scollops above the grey and it doesn't do the house justice. What colour was there before you painted the grey?? considering grey is a more modern colour I think you were attempting to modernise the externals. in saying that the roof would have been better to paint charcoal the cream in white and then the grey and then the driveway would be done in a grey stain. but if you leave it the way it is and cover the red scolloping above the windows the same grey and the bricks below the windows near the ground grey as well then get the drive way restained to the reddish colour of the bricks on the house and then it would blend more and look inviting.

I’ll leave the actual plan ideas to the generous brains trust here on Houzz but you seem to have plenty of room to create a bathroom and a laundry. Is the house in suburbia? Are you planning on selling soon? Will you and family get the use out of a new bathroom? You may be happy with the price as is, and leave the Reno to the next owners.

. Concrete is fine on pinterest, it's even fine in corporate canteens but it's not a homely feel at all. If however you are sold on the look but want a more removable option I can recommend lino. NOT vinyl but real, Lino. It's a different thing, harder wearing than vinyl and can actually look very chic and more closely match concrete look without creating an unpleasant surface to walk on in bare feet. The worst thing about hard floorings like tile and concrete is they are unpleasant on your feet in winter. I live in a house with lino however and it's much warmer and a better feel on the feet than a hard surface flooring. Easy to care for and importantly easy to remove when you get sick of it. Marmoluem is a true lino, which BTW is actually a very sustainable and organic product. Lino is made from jute, seed flours and linseed oil. It's compostable. But it's unique composition is what also gives it a warm and beeswax like feel underfoot, which is very comfortable. You can get it in a some very nice concrete like shades, patterns and even raised textures. It's a sheet flooring so there are few joins, something tiles cannot offer. Tiles, once stuck to the floor are an absolute b****h to remove without a lot of damage, noise and expense. Lino can simply be lifted like carpet.

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.
