There is insufficient under floor space for a deck to be done well. Timber really needs room to breath otherwise you face the possibility of cupping (when the boards bow upwards on the edges). If you want to deck (and it would look OK) you may have to remove the concrete and lower the floor area (ideally above 300mm) - The porch area could then be extended. Your other option is a timber look tile (yes they do exist) or just tile the floor)

sounds exciting but i wonder if bugs would move into the space behind the glass and what would you use on the floor? i have seen a whole bathroom including the shower done very successfully with a render used for swimming pools and usually painted but this one was just plain concrete colour with a slatted timber floor mat in the shower, timber vanity, white toilet and handbasin and it was gorgeous, good luck with you tile free shower

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.

Thanks for all the feedback! I was leaning towards keeping the original roof colour, to be honest it was my partner who wanted to consider other colours. So these comments have mainly assured me the original is ok! A brown would have been my 2nd choice. The challenge will be hiding the new mis matched tiles. I hadn't thought having the roof painted would require extra maintenance in future as it is already painted concrete tiles. My last house was the same and pressure washing it removed alot of original paint, leaving it patchy. So ended up getting that one repainted. That house was 10 yrs older though. I feel like painting the driveway would require more maintenance, but I would love to get it done properly to tone down all that orange! And yes one day soon a new garage door would be good too! I've thought about bringing brown/timber into the exterior but am scared there will be too many different colours going on if i dont do it right! So the decision on painting the roof (the same/ similar colour) after tiles are replaced is on hold for now as we are looking at adding an extension with 2nd storey at the back. If that happens we will want the new roof to match the existing. (I think!) Thanks for the ideas, much to think about!
