We have a 18 year old al fresco area, which is about 140m^2. The retaining wall was not correctly installed when we purchased the property, and will need to be replaced we are looking at reimagining the area to allow for entertaining and to incorporate a herb/vegetable area, replacing the paved area and also reconsider the garden. What advice do you have for including the the deign? After decluttering, we‘d like maybe cafe blind to enclose the area from the hot Australian sun/heat. access to the property is only a 980mm gap in the side of the house, which is problematic. Would you suggest replacing the retaining wall, or building in front?
