People spend much more time at home than they used to. So, most of them prefer to have a green backyard to have a barbeque party or play with kids and home pets. Mow the lawn behind the house, replant bare ground with grass, prune trees, bushes, and hedges if you have them.
After that, you may start with the front area. Plant lots of beautiful, colorful flowers in the front garden to give a positive perception of your home. Make the area around the house attractive, not just the house itself. It also could be the laying of new turf.
A house would look a lot neater if the turf is repaired or completely protected. Adding decorative features that are easy to install and are made of very dense polyurethane foam will be much less costly yet nice and pretty.
