Generally speaking, city gardens are relatively small oases of green in-between buildings. Here, we often focus on maximising the possibilities for atmosphere in the garden and to balance out the live material (green) with the dead (facades).
Contrast between the interior and the exterior is unavoidable, and sometimes it is even interesting to accentuate this.
A great landscape design is very important in this situation for this reason, to make optimal use of the available space. When creating a design for a city garden, the landscapers always take the measurements of garden furniture and planters into account. Nothing is left to chance.
