Without a good picture of the entire home, it's impossible to have any opinion at all.

"round green velvet shrubs along walls, Nandina, perennials and a crape Myrtle' is pretty much typical builder's junk. DIY won't change that.

Hence the question... what do you suggest?

As previously stated: Without a good picture of the entire home, it's impossible to have any opinion at all. Same goes for the builder's tree hiding your house.

Here are pics of full house

Also thinking of taking that tree down as it blocks view

Yes the builder's tree can come down in favor of a new tree on the left side of the house. No need for a Crape Myrtle on the right since you already have a right side tree.

Before planting new foundation shrubs, the narrow front walkway and angled bottom landing (bad) to the front entry needs to be upgraded.

Any suggestions for shape!

Sorry, didn’t mean “!”

Thinking of a small purple Crape - right bed corner. If not, would you just leave the corners of bed open?
