Garden Design

I am planning a new build home and would like to design the perfect garden for myself. I am looking for a modern/contemporary design. I am also looking to externally design an outbuilding. The outbuilding idea has already been designed by my architect but I have decided to relocate it to the right side of the garden which I have taken from the other house. The design has roughly been done but if you can improve on it that would be even better.

I have quite a good idea of what i want but i'm also looking for some input to improve on my ideas. I am looking for a 3d design.

Here is an areal video of the two properties: https://youtu.be/EVlIOiXFu0Q

The garden fence is still there but that will be removed.

In the documents attached below you can see that im planning to take most of the garden of the other house. The blue line is where the new fence will be. And the red line is the new house shape. You can also see this in the architectural drawings of the house but the architectural drawings only show half of the garages but in reality its both garages coming to the house on the left and turning into a large kitchen/dinning area. I want to place these in as a reference so the whole property can be seen in 3d.

Ive attached some images of what I like and looking to build around these ideas. I like a mixture of decking, artificial grass and that white slabs type maybe around the pool and the planting area around the fence. this is quite a big garden.

Lighting is quite important to me so i would rather have too many ideas that then we can remove if they dont look good rather than too little.

I wanted to have a hot tub/jacuzzi next to the pool in some way and maybe a pergola type in the top left of the garden but im not 100% sure of the layout yet.
