Need your thoughts for garage design to minimise presence

Thanks for the ideas so far.
Anyone had any experience/understanding of what you can/cant do with a slope leading to a garage? I am finding it hard to visualise what the limitations are for the excavation.
I would have thought the ultimate limitation is going to be the depth of the local drains; if the garage floor ends up lower than those, then surface water will run down to the garage floor level and you won't be able to drain it away without some sort of pumped system.Anyone had any experience/understanding of what you can/cant do with a slope leading to a garage?

The next limitation would be the steepness of the slope you'd create and the space available for a transition into the slope, though again without being able to see the pictures I've no idea if that would cause you problems.

From the side elevation you can see that the garage floor is above road level so surface water/rainwater drainage will not be a problem.
Yeah, the garage floor is shown at reference level 8.8m, with the drain connection to mains at 8.2m. So looks like I couldnt go any lower with the excavation, given the drain needs to be lower than the garage floor. Maybe 20cm or so.Dig it in another metre, shallower roof pitch and skew the garage more toward the drive entrance/parallel with the front garden wall/boundary entrance so the blend into the existing drive gradient isn't too insane.
The extreme/Bond villain's lair answer is to abandon your plan and replace it with an entirely subterranean garage beneath the drive. Making the drainage work would be a bit of a cow but not impossible.

That would get seriously expensive and comes very close to the front of the house, and therefore I assume close to a living room or similar.The extreme/Bond villain's lair answer is to abandon your plan and replace it with an entirely subterranean garage beneath the drive.

It depends where the main drain is and how deep.
In the first picture in my original post you can see the main pipes running straight from the house to the road. The connection to the main drain on the road is indicated by the rectangle, on the road boundary, and shows the level as 8.235m. Ground level is 9.2m, so the floor of any underground garage would likely by 6.5 to 7.0, hence a 1-1.5m vertical difference to pump garage drainage to main drain.kryten22uk said:
