I'm after some suggestions for our front garden situation. As may be apparent by the influx of threads, we've recently moved in, and am due to receive some inheritance shortly. As such, with two cars, we are looking to convert our front garden and single concrete driveway into a blockpaved and landscaped front, accommodating 2-3 cars.
I've had a local top-rated landscape/driveways company around, Wilkinsons, who have provided several drafts, however there is a bit of a stumbling block.
Our front garden has a tiny sliver, which according to the neighbour and boundary plans, belongs to them. What this means for us is that there is a quite literal 1.75ft wide and 5m long strip of grass down the side of our house up to their fence boundary. On the neighbours side of this strip is a public footpath, and the neighbour's block-paved driveway. I've attached a very crude sketch of the boundaries under discussion here:

The current neighbour has agreed to let us block-pave or landscape this section to match with our own driveway at our own expense, which is fantastic as it would look really odd block-paved up to a strip of grass. However. HOWEVER...
They are elderly and are going to be moving out and selling up soon, which therefore would permit the next owners the ability to change that land however they see fit. They do not wish to sell us the land, or modify the boundaries at all either.
So as we had planned to block-pave all the front, it looks like we will either have a very odd looking front, or will potentially have a waste of money down the side of the house, or a ticking timebomb if we get an antagonistic neighbour.
For the record, we pay to have this grass and land maintained as it flows directly from our garden, and to the untrained eye, looks to be ours.
What do you think we should do?
