How can I redo my front yard?

As for the lawn, after you fill it in, check out stepables for a no mow lawn on the slope. Choose one that will grow in your planting zone and conditions.

Shrubs (evergreen and flowering) and flowers along the house would look nice. Check out your local garden nursery for suggestions.

If you whitewash the red brick, the stone that's around the garden will be a closer match and the part along the steps and the face of the house will match better. It will also brighten it up.

Maybe a few large stepping stones randomly places, some large, med, small plants to depth.. n a few bags of grass seed !!?? N maybey smaller rocks if you'd like to put around stepping stones.. dont forget weed block net !

On the cheap I would use wood chips, spread out over the yard, then figure out what the next step on the cheap would be. Good luck.

The flower bed edging on the right side of your porch appears to be in good shape, and since you don't want to spend a lot leave it as is. Plants will be the focal point. Fill the front bed with an easy care perennial. I show German iris, but choose whatever grows the best in your area. I also show a low shrub beneath the windows. Make sure to note the mature height and spread of shrubs. Dwarf only means smaller than the species, so some dwarf plants can still get really tall. Don't plant too close to your house. Once again, pay attention to how wide a plant will grow. If it is expected to grow 3 ft wide plant it 18 inches from the house, otherwise it will lean outward. On the right corner I show a taller shrub with a low perennial beneath it. If this corner gets the runoff from your gutters make sure the shrub can handle wetter ground. I've covered your lawn with a ground cover. While all these plants are shown blooming together, you should look for plants that bloom at different times of the year so there is always some color in your yard.

All the plants shown are at or near their mature sizes. Remember that it will take several years for plants to fill in. Use annuals in the bare spots until then. Blue and white flowers blend easiest with other colors. Your brick, trim and roof all have red to violet tones, so I would avoid orange and yellow flowers. Nonetheless, rules are made to be broken, so if there is a flower you like, give it a try.

For the step side of your yard, start by either leveling the area in front of the top step or filling it back in with soil. Just clean it up. Perhaps you could plaster over the exposed concrete using some colorant so the plaster looks more like the top. Right now part of your porch floor appears to be painted on the left side but not on the right. Paint the whole porch so it matches.

I think you should put low growing shrubs next to the steps. Plant them far enough from the steps that they won't trip anyone as they grow. In this scene I show a dwarf conifer instead of the broadleaf shrub I showed in the first photo. I do think that shrub types should be repeated across an area. I just wanted to show a slightly look with this photo. I also placed a white flowered perennial in front of the conifer shrub. I repeated the blue flowered ground cover across the lawn. There is no reason you can't mix ground covers, but you will get a less formal look with random placement.

I'm not specifying the species of plants because you should check with your local nursery people as to what will grow best in your area. Show them your photo so they can see how much slope you have. Generally, you should put plants that prefer well-drained soil at the top of a slope and those that appreciate more moisture at the bottom.
