I would like some suggestions for our outdoor space. Are there some apps that I could use for free / trial in order for me to better visualise the outcome? It's an L-shaped city garden, the house is modern so I would like to keep the modern feel outside as well. I am thinking dining area in the right side of the first picture and kid's area in the third picture - climbing wall, basketball court? Need something tall to get some privacy from the neighbouring apartment building - maybe trees, what type of tree, how long until they're grown? Thank you so much for your input!
