When you're laying out walks, you need to begin with a PLAN of the property (relevant area). It's the easiest way to think about it and discuss it. since the house is new, you most likely already have a plan drawn that you can use. Please scan and upload the portion that would contain the proposed walks.

There is a tendency to place walk too close to the house, thinking that since there is nothing else there, the walks would look ridiculous if placed to far away. One must think of the bounty of foundation planting that should be there before placing the walk.

some ideas

The houseplan?

I tend to make my beds 8'-12' deep for foundation plantings and leave something like 1'-2' between the ultimate size of the plant and the building so we can do maintenance such as painting, cleaning windows, etc. and so the building doesn't have plants holding moisture against the wall. So you have to do research on sites like the Missouri Botanic Garden's Plant Finder to figure out how large plants will realistically get, not just what the plant tag says which is typically size at 5 or maybe 10 years. Use that ultimate size expectation to place plants so you don't have to prune a lot.

Use the house plan along with all the area around it that you want to have structures or plantings (including garden beds, trees, hedges, etc.) plus any hardscape such as patios, walkways, and the drive. Though you don't need the interior details of the home itself for your outdoor plan, you do need to mark doors and windows as well as any rooms that might influence outdoor choices such as the kitchen and downstairs bathroom so access to those are easy. I like using 1/4" graph paper to make it easy to draw things to scale. If you have one master plan, then you can print copies to work out ideas for particular areas.

Yes house plan. Trace the first floor exterior walls, then add driveway. Voila ... you have a PLAN that can be shown here.

You appear to have a generous amount of real estate to work with so be generous as well with the layout. The comments above about creating deep beds are very appropriate......it is not so much the scale of the house that determines sizing but how the house sits on the lot and how the layout or placement of beds and activity areas relates to that.

Make sure that your walkways and paths and any landings/terraces or patios are generously sized as well.

And nothing defines a good landscape as well as trees and you seem to be devoid of them :-) I'd take some time considering placement, sizing and selection of trees to give the property some immediate impact. Even smallish, young trees can begin to define how a landscape will develop. Consider them as well as for windbreaks or to provide shade and summer cooling. Doesn't look like privacy now is a big issue but will it be down the road? If so, plan for it now as it takes time for privacy from screening plants to develop.

You have a huge yard. I would start by putting in some trees and larger shrubs.

How to choose plants? One of the best ways is to see what other people in your area have done. You can search Houzz for ideabooks. https://www.houzz.com/magazine/10-ways-to-use-ornamental-grasses-in-the-landscape-stsetivw-vs~54589007

Brody, it would help to show the surrounding area outside the house better. Something to scale on graph paper. It should show measurements. Since you know the area of the proposed concrete pad that should be indicated too.

Privacy will never be an issue as we live on hundreds of acres. I am no rerouting my driveway, people can walk on a curved sidewalk. I love the sun in my home so have been leery of trees due to indecisiveness on where to plant them. I dont want to block my views or shade my windows.The x's are things that are no longer there.

I tend to lean more on the architectural side when it comes to hardscape, so a rectilinear walk with some interesting returns would be nice. You can't go wrong with curvilinear, but just make sure you keep your curves long and avoid quick, choppy arches. With it being your private walk you don't need to be overly concerned with shortest distance from A to B. As far as landscape beds go, your planting plan should dictate the size and shape of your beds. Setting the beds prior to finalizing a planting plan could backfire. Either you'll pigeon-hole yourself with not enough bed, or you'll overextend yourself with beds too large once the final plants are selected. The plant to mulch/gravel ratio is far more important than bed to house. Too much void space looks unfinished and not enough could look overcrowded, unless you are going the groundcover/perennial garden route. Good luck with your project.

1. Thanks for posting the plan as it shows the proportions of the house. Don't mistake my drawing as explicit scale as I'm freehanding over the plan. Exactness is something you'd work out on your own "to scale" drawing, incorporating specific measurements that satisfy your requirements. What I'm showing here is a SCHEME that resolves a route, taking into account a few particulars. The plants shown are simply "likelihoods," given the location of house corners, windows, stoop, etc. It is not intended to be a complete planting resolution. A few things under consideration are ...
2. 1. trying to keep the walk far enough away from the house that there is adequate room for foundation planting. At the beginning, it might seem that the walk is too far away from the house, but that's because the planting bed space is empty. As soon as plants develop, the placement makes sense.
3. 2. Connect walk to drive near BACK of where a car parked outside of the garage would be, not the front. It's an easier way to approach entering the car and still have space for planting.
4. 3. While allowing planting bed to "wrap" the right porch corner post, don't plant directly in front of the stoop. This should be a spacious landing. Extra walkway space is needed at each end of the walk, where it meets the stoop and the drive.
5. 4. Align shrubs with windows (as one would align steps with a doorway) and coordinate trees with house corners. Fill the remainder of the bed with groundcover, reserving space for annual color (near entrances and walk connection points) and some placement of perennials for periodic color and interest. This is a scheme that does not end up smothering the house with shrubbery (which you'll rip out in 15 years) and is easy to maintain.
   

Many garden catalogues will offer pre-planned gardens. They will sell you the plants and the planting plans. American Meadows has 16 pre-planned gardens. Bluestone Perennials has 11. High Country gardens has more than 30. I live pretty far north, so I like catalogues from northern garden centers. You want to figure out what mail-order catalogues are a good match for you.

If you live on hundreds of acres, I'd plant some trees far enough away to not shade your house. In fact, I'd plant an orchard of varied tree fruit. While people will tell you that you need to prune and fuss over your fruit trees, if you get hardy species and don't fuss, you'll get a good crop some years and not much in others. And if the birds eat all your cherries, you'll still have the lovely bloom in the spring and the pleasant chirps of the birds.

Just pointing out here that a "preplanned garden" is not anything close to LANDSCAPING. These are not even on the same continent in terms of meaning and utility. Landscaping is going to be specific to the site and its conditions, including the structure. Any "generic" landscaping ideas would be hit or miss, and most likely, a miss.

Right, but asking for advice on Houzz is pretty hit or miss, too.

For starters, one must be able to discern good advice from bad.

Brody I hope you will not limit yourself to grasses. Most people want something for winter interest.

Trees can be planted at a distance so as not to shade the house.

Grasses are wonderful in the winter!
