Thanks for all the suggestions. Off-white with a bright colored, mid century door was the direction I was leaning, so it sounds like I’m on the right track, @emmarene9, I think the small plants are boxwoods, but I am going to pull those out along with the stones and redo that bed with some more mid-century appropriate, Texas native landscaping - maybe grasses or succulents. And here’s a close up of the iron scrolling that you asked for (dirty and coated in that ugly green paint, but in good shape otherwise).

Hi, the key consideration to work with is that the home is not MCM, but Ranch, and should be treated as such. Unless you want to engage an architect to change the roofline and windows, you should work within the Ranch style. I suggest you step back and reassess the design approach and consider "modern/updated ranch" vs MCM, in order to pull together a good overall design. With that in mind what needs to change first is the front door itself-it is out of sync with the house (color and style). Adapting the front entry to add a sunken patio is intriguing, and in line with Modern-Ranch approach. Minor comments: color, as that is not my strength, but if you're going to live in it vs sell then do what you like. I agree with the suggestions of the landscaping updates. For better or worse you have a huge tree too near the house that you'll have to deal with. The small one should be moved sooner than later as part of the overall plan. You have a huge front yard to work with but unless you're a gardener, I would suggest not doing too much beyond anchor plants and then add potted plants for pops of color-but those minor items alone will do wonders for the look.

Landscaping for a ranch is mostly low shrubs or perennials punctuated with taller shrubs to break the long bland sameness. However, your home's style is anything but bland. Below is a mockup of this basic landscaping style. I've placed 2 sets of tall narrow broadleaf evergreens to flank windows. These happen to be Ilex crenata 'Sky Pencil', but they may not work for you. Between them is a medium sized flowering shrub. In front of these is a perennial edging or groundcover. Yellow flowering shrubs or perennials fill in on the corners and flank the entry. I don't know how wide your flower beds are between the house and the walkway, so I don't know how much room you have to layer plants. The point of my mockup is to show how plant types and color are repeated. Consider measuring the length and depth of beds and drawing out plans where 1' equals 1" on paper. You can use this to get an idea of how many plants you need to fill the spaces. Visit your local nursery for recommendations of plants that will work in your climate and soil. Pay attention to the expected mature size of plants. If a plant will eventually be 5' wide plant it 3' from a wall or walkway. This could mean that instead of the one medium sized shrub you have to use 3 smaller shrubs that won't crowd your walkway. Remember that "dwarf" only means smaller than the species, so make sure the mature size will fit. New plants will not fill the space for several years, so fill in around them with annuals and biennials. I have not covered the water meter, but it shouldn't be noticed among the plantings. Use taller annuals or biennials in front of and around it so the eye is drawn to them. As shrubs mature the water meter will be less and less conspicuous.

I like the first light fixture better. (Nothing to do with MCM meaning my opinion isn’t based on that...)
