Oh, and a few months ago, I was playing around. This is what came as the result :D

The owner of this urban terrace house wanted the small backyard to be a mini-retreat that could be used as additional living space. By removing the lawn and extending the courtyard area slightly, space was created for a dining table and a sun-lounger with space to move around. A small utility area doubles as space for a productive vegetable garden. As planting space in the courtyard was limited, plants were selected that could add drama and lushness without taking up too much space. Bold colours and textures and strong vertical lines from the canna lilies and clumping palms create the feeling of a lush tropical retreat all-year round. The pine timber fence was stained with Resene Waterborne Woodsman "Iroko" which forms a rich backdrop to the courtyard. Before: After: Check out the entire project here!

You DO have a steep slope to deal with! The tree roots will help stabilize the soil and make a mudslide less likely. If you cannot mow the lawn safely, terrace the area (think Machu Pichu) into garden beds for flowers or vegetables. Do you want your children to play on a grassy area or on a man-made surface? Be sure that the play area has shade during the hottest part of the day. Best wishes.

I want to put a pergola/all year round building in my back yard, but am unsure on what design to do to make sure I get shade in the summer when needed and sun in the winter when required! any advise or direction welcome one stumped kiwi Moana
