I agree with Oldest - you can make the outside of this house look twice as attractive by softening it with planting and paint and doing something with the drive.
We transformed the look of the outside of our house by painting the formerly white door/garage door a grey-green, growing a beautiful variegated creeper and jasmine around the front door, planting hardy, scented herbs and shrubs (a double row of lavenders along the path to the door, for instance) and some roses. And getting a much nicer house number, rather than the twee horror the previous owners had left.
If you're unlikely to 'need' the sloping lawn next to the garage as grass, you could make it a kind of informal rockery with good planting - heathers and small shrubs? - and link it back to the house by growing a creeper up the 'blank' side of the garage.
You can give yourself a head start with climbing plants by buying a bigger plant to start with - I think I paid about £80 for a creeper to train up the side (and eventually around the top of) our front door, but it was well worth it.
