For your garden, I would recommend you a colourful design full of green and orange and lemon trees. I have divided the space into elongated parts which separate the grass, from the bushes and the terracotta tiles from the gravels. The design gives a lot of space to the green parts where grass, bushes and flowers (on the ground or climbing) create a feast of colours.
There are two kinds of shelters: A heavy one which protects the areas where a lot of activity is allowed both in summer and winter and this shelter is made of metal construction and red tiles. It is non-removable and it is located on the area of the outside dining table (outside the kitchen) and the area where there is already a shelter. This area can be used as a barbeque area or a hobby area (there are handmade stone constructions for tables and barbeques, while the ground is covered with gravels). The other kind of shelter is a light wooden construction which covers the rest of the area (east area and the entrance of the house), as well as the entrance of the garden which can be used as a shelter for the car. This is made only by wood, where the sun can partly pass from the widely spaced timber planks of the roof. When there is a need to be protected by rain, there is an electrically removable canopy which covers the timber planks. It is a very light construction, and I believe you will not need to use the canopy a lot of times, because the partly protection from the sun is made by the timber construction alone. If you use some climbing flowers, such as an arbour, in both kind of shelters, it will change immediately the space!
Finally, I inserted benches under the lemon trees, small metallic tables for an evening coffee on the east side under the timber beams, stone tables in the hobby area, and a good dining timber table with a timber auxiliary space outside the kitchen for protected beautiful nights and days.
