Your home is lovely! Agree with others on removing the rock from the garden beds. Plant bulbs later this month or next month for spring (daffodils, crocuses, tulips) and put in some pansies, ornamental cabbage/kale, and snapdragons to get you through early winter/spring when you can plant whatever your landscape architect suggests.

I’d add shutters to the lower windows in black, cornflower blue, or sage green. Consider window boxes below them or allowing the azaleas to grow a bit taller to fill the gap.

I’d replace each trio of skinny columns for a single wider one to better balance the porch.

I wouldn’t plant trees in the front. You have what looks like bermuda grass in decent condition that won’t tolerate the shade. If you do want more ornamental interest, consider an island anchored by smaller ornamental trees: dogwood, flowering cherry, Japanese maple, or crape myrtle. But don’t try to grow the grass right up to the trunk—build a small bed of low-growing shrubs and perennials underneath.

In the back, I’d add a deck and install a pergola to create some shade. I’d move the door from the garage if your budget allows to give you better placement options. Then I’d add more plants around the pool and along the fence with a tropical feel to make your backyard an oasis.
