I think a block would look ok, if painted black externally. Bricks do look nicer though.
I'd be concerned how they tie a solid 100mm thick block to the floor? In my experience, a block bedded on just mortar on a concrete slab has no strength and the slightest knock sees them breaking away. The photo you posted has hollow blocks with rebar no doubt embedded in the slab to tie it all together, much stronger.

There are a multitude of stone effect blocks. I would think some must be at least the 7Nm.
But as said, if it is just one layer I would want some extra anchorage. If you put a workbench against them and get a bit heavy handed it will soon make them loose. |

This is mine. Engineering bricks and larch cladding. Ignore the fact that the slab is proud of the ground, this is due to varying ground level across the site. On a flat site only the bricks would be visible and the cladding would finish around 150mm above ground level.

^ That's a neat easy solution for holding the walls down.
Our ground 'level' is far from that, the areas all over the place.. I think it maybe we do it using the blocks and just see what its like. |

I need to start on a new garage soon. Are you guys digging foundations or using a floating slab? I have nearby tree roots I'd rather not disturb. WARNING.

zed....
Tree roots.... Oh my .......follow my other build thread. I've had some trees removed and stumps ground out... Then we had 3 tree stubs behind where I need to shutter up to. I will add pictures soon on the other thread as we only removed the last weekend. I'm re floating where the old garage was but the new ones a big bigger. I also moved 6 tonne of crush last weekend and need more... wait until you see our garden. Its turned into a bigger job  |

Mine is on a single mass concrete ‘floating’ slab. The ground is almost solid slate waste so no need for strip foundations given it’s a timber structure, though if I had built it in blockwork I would have done it that way.
If you’ve got clay or the like then all bets are off and you’re into structural engineer territory. |

We are on clay. I guess that means I'll be playing on the digger then? WARNING.

Clay is the worst you will have to deal with heave when you cut the water demand from the trees, also consider hedge planting this may be a high water demand too.

Agree - those were existing garages I extended/modified for clients - pics to show the weathered concrete blockwork. This is one of my own, on edge of conservation area so I had brickwork covering the blockwork, lead flashing dressed up behind breather membrane & lapped over top of plinth: Click image to enlarge |

Rosco
I have not seen them thanks, I will stop at my local builder merchants and talk bricks with them. I'm coming round to the pictures of the blocks as they are, the concrete in front of the garage will have gravel to finish off and it may not look so in your face... once everything else is done 
so a couple of weeks ago this was our garden... Click image to enlarge couple of weekends later Click image to enlarge and currently it looks even worse as we aim to not only to sort the base for the garage but we have now also attempted to level our garden a bit and install a soak away |

Just saw a video on these ground screws yesterday and the system looked interesting: There's something in the comments quoting "The cost was about £100 per screw installed, this can vary on quantity, length, location etc," and "A concrete slab that is engineered not to fail and meet building regulations for this build would need to be a proper reinforced raft and it would cost well over 10k maybe even 15k". https://www.facebook.com/GravitasGS/ Click image to enlarge |
