What a beautiful home to have this sort of dilemma in !! Corner seating will look interesting in the recess where the wheelbarrow is maybe !?

thank you for your comment I had not thought about that idea/space.

a curved walkway would be ideal.

I would take my inspiration from the beautiful arched window you have and use that shape flipped down directly in front of it to form the centre piece of a lower deck/ patio area maybe as a water feature, then have simple rectangle linking in the seating area I mentioned earlier and another arch at the steps

very interesting idea thank you for your comments
