Paint all of the fences the same colour, multiple plantings, some seats under the pergola?

same as Emma and Lesley and add the steel height extender/lattice across the full width of the back fence, same colour as the fence and block out the view of the neighbours

what kind of seating do you see under the pergola? and how could you place it?

What is floor size of pergola?

For the pergola, I think you need some height, such as a series of tall plant stands with some leafy plants, a vine growing over the trellis-type bit at back corner of pergola, and a few Acapulco chairs and small table, and/or some big outdoor floor cushions. It depends on how much space you have and how you use the area. If you want it for dining, you can get a batching Acapulco dining table. Some white fairy lights strung from beam to beam would be nice too.

With regards to the pool area, perhaps tile, pave or concrete out from the pool coping pavers so that you have a seating area. Some nice tall plants in matching pots and solar path lighting around the area would be nice. You could continue the solar lights on both sides of the pavers leading to your pergola.

I would try to link the gazebo to the pool by better landscaping i nside and outside the pool area. At the moment it does not flow. I cannot see a pool gate near the gazebo.

No it doesn't flow does it.. the pool get squares off the pool.

Lush Planting, Palms if you are in the right climate, grasses, boulders, stones, maybe climbers up the pillars etc. Let your imagine run wild. If you are not a plant expert consult your local garden centre - take in a copy of the pictures you have shown us.

Hi I am in the right climate for palm I'm in the Gold Coast.

Lighting can also be utilised to tie the two spaces together as well as enhancing the great entertaining/ swimming space.

Had you considered reconfiguring and adding to the pool fence in order to incorporate the pergola inside pool fence boundary? I can certainly understand there are pros and cons to this, but I thought I would throw it out there. In any case, landscaping, lighting and painting pergola a more harmonious colour seem very good ideas to me. If you sketch out on paper some of the various plans and ideas you like or have in mind, and colour-in the different features, this might help you visualise things better. It's sort of rudimentary, but I have done it several times and it did help me 'see'. Best wishes, and please keep us posted on how you are going.
