I am looking for a word which would sum up this process - you have a plain backyard, and you place there a table and chairs, build a playground for children and plant some flowers. And now comes the word: the backyard is ..... (facilitated?).
There are lots of possiblities, but maybe "improved".
We're going to improve our back yard with some decking and a play area.
Renovated (if you are restoring it to a good state)
Our back yard was full of weeds, so we dug them all up and renovated it with new plants.
Revamped is a casual way of saying the same.
