Original ecosystem if each area was maintained as much as possible, while green spaces in new areas were added by planting more trees, developing unused lands, building exterior, balconies, roof deck, and interior halls, horizontally or vertically.

Vertical Garden

A vertical green space or vertical garden is an art of organic architecture that could be with or without structure, and diversity of plants could be determined to suit characteristics, environment, and ecosystem of the building and its surroundings. According to types of equipment used, vertical gardens can be divided into the following 5 types.

1. Felt system

is used with small to medium-size plants in fabric bags containing suitable soil, being attached to a wall. Geotextile fabric bags are popular as they are light-weight, able to preserve humidity well, water permeable, do not support growth of fungus, but support plants roots to attach to them.

2. Panet System

looks like panel or tray with holes to contain soil for plants. Material used could be plastic or light-weight metal attaching on hanging frame or hanging wall for building decoration.

4. Planting Block Wall

are concrete or clay walls with holes for plants to adhere to the structure or it could be built as a permanent wall with water dripping system through the block in each layer to feed them with water and nutrients. This system is popular for indoor plants such as golden pothos, hoya, dischidia, rhipsalis, and outdoor plants such as dragon’s tongue, red and green sissle joyweed, weeping willow, purple heart, etc.

5. Climbing Plants on Trellis System

can effectively prevent the heat from entering buildings by planting climbing plants in trays or other containers and let them climb on the wall or structure until it is full. Popular plants for this system are coat buttons, skyflower, Javanese treebine, easter lily vine, etc.
