It is not always easy to design a sloping garden. These are more difficult and complex to design than level ones. While designing a sloping garden, one has to face several practical problems and those need to be solved before having a well planned design. The sloping garden may require a level ground, such as patio, children's play equipment, sheds, seats, greenhouse, swimming pools, ponds, pergolas, tennis courts, and so on. Usually three common ways are used to create terraces on sloping ground, i.e. cutting out, filling in and or a bit of both.
The situation becomes more complex when you have to design a sloping garden on a very little available space for terracing. And usually the design is based on cutting into the slope rather than any filling. This clearly rules out the probability of any excavation work and shows that efforts of a structural engineer are required to have a proper framework for main retaining wall as it is very close to the house. To protect the neighboring land from excavation, a stepped retaining wall is used down at one side. While on the other side different display ensures that a gap between the retaining wall and the fence allow planting on a slope. 'Fill' is only used in this garden to make the projected land over the lower part of the garden along with the front half of the upper paving. The large projected landing that is formed is best for placing tubs or pots grown with colorful flowering plants.
If you feel that the outlook of the place is not giving the desired looks, you can replace the tubs or pots with a deep planting pocket that will hold a conifer or large evergreen shrub. As there is no grass in this garden, so maintenance work will be rather easy. The upper and lower paving should be of same shape and style and are decorated with pots and tubs containing colorful flowers. The main part of the terrace will also contain tubs and pots or planting pockets.
As you have cut out the area from a slope, you must need some excavation of reasonable depth at the borders to make room for topsoil. If you are willing to plant shrubs, then the ideal depth should be 400mm (16 inches). Sunny areas are usually preferred for herbaceous and annual flowers, whereas shrubs should be preferred for the shady areas. It is not a good idea to include any trees in this small garden as they may cause a shade over the entire garden. However, you can use some from of conifer trees at the corner places or for screening the eyesores.
