I would render the bricks ..paint the boards and garage door a darker colour..

change your window frames so they are all matching..the little ones don't match the big ones

the rails on top can be changed to something more modern ..

you could also remove the weather board cladding..and replace it with brick cladding sheets then that way you can render it to match rest of house..

I actually don't mind the brick - adds a bit of character to the house. I agree that the windows need to match, and I don't like the railing on the balcony. I'd be inclined to paint the garage door a darker colour, and do something about the garden area right in front of the concrete entry way/terrace.

I agree with the Uyenvy, but i would also suggest some climbing plants to soften the walls. Star Jasmine is a reliable climbing plant and you could train it to grow where you want it to on tension wires, could even create interesting shapes with the wires and climbing plants.

I would paint the weatherboard cladding and potentially the garage door charcoal or another grey colour. If they're not grey already, I would paint the gutters, etc a complimentary colour. I would consider going bold with the front door, maybe gloss black.

Some plants on the front porch will help to soften the entry a little. It may also be worthwhile getting the driveway professionally cleaned and getting a matching path to the front door to replace the current pavers.

If the window above the front door is open to a void, I would think about installing a really nice pendant light there (i.e. so it is viewable from outside).

Finally, the balcony appears to have an odd, secondary balustrade (perhaps the brick isn't high enough). I would look at either removing it (if Council regulations allowed removal) or replacing it with something that would be naked to the eye.

Keep the natural bricks.

I'm just not seeing a problem with this house. Freshen up with paint, and relax.
