...here's all four, after a bit of fiddling ...

steps
raised bit

My questions really arise from the weathering you see and how it was all laid down 2y ago.
1. Blotching on the slabs. Could this be due to standard mortar being used directly under the slabs? Its as if damp in coming from underneath.
2. The wall still has efflorescence but less than it was; could this be due to the retaining wall having no concrete support or damp membrane, soil-side?
3. Those bricks for steps look permanently damp and are growing moss as you can see. There was no concrete support under these brick - they were laid on mortar only.

Crossed joints. Very naughty!
I think it *is* Modak which is a porous stone prone to algaefication. The weak-looking joint mortar is probably acting as a wick for moisture.
Can't comment on the bwk eff as that stuff is a law unto itself!
Step moss - probably due to them being a porous substrate on a bank which will be fed by moisture from the upper garden.

Pete,
I can only comment on the look of the patio, and it is nothing that a good clean wouldn't cure for you.
There is one of our mixes in the stain removal section on the main site that would sort this for you.

Were also planing to increase the size of the interior showroom. We need to move most of the staff facilities into this new building to create space to renovate the interior showroom. It needs plastering, decorating and carpeting. Should be done within 2 weeks

looking good steve
apart from picture 7 :;):
what bond is that ? brook bond
to half bond block work you have a 100 mm cut in alternate corners,or a 3/4 and a 1/4 every 2nd course
just breaking your balls mate shows a lot of forethought
