Do these items add to home basis?

It's common knowledge that replacing the roof of your house adds to its basis. What about these items?

 

  • Replacing 2 34-year-old creaky wooden garage doors with modern steel doors with WiFi enabled openers
  • Replacing all the, yes, 34-year-old landscape and hardscape around the house (to conserve water, improve fire safety, and modernize the appearance)

The garage doors are in the mid 4 figures, but the landscape/hardscape will be in the mid 6 figures (ouch). I believe these will add to the value of my home and considerably prolong its useful life.

I looked on irs.gov and couldn't find anything more informative than this in Pub 530:

Improvements.

An improvement materially adds to the value of your home, considerably prolongs its useful life, or adapts it to new uses. You must add the cost of any improvements to the basis of your home. You can't deduct these costs.

Improvements include putting a recreation room in your unfinished basement, adding another bathroom or bedroom, putting up a fence, putting in new plumbing or wiring, installing a new roof, and paving your driveway.
