A plant that is native to another part of the world but has been introduced anywhere else is an exotic plants. Similarly, exotic roof garden have plants that are not native to one's place.

Semi: - A small split-level roof garden, which is cluttered with rubbish and a hotchpotch of different materials, is transformed into a slick modern roof garden. The space is divided up into two separate areas, each with its own character. One is funky and colorful; the other calm and relaxing.

Paving: - Bespoke paving is used throughout the garden to create a sense of unity and harmony between both spaces. The paving has tiny flecks of metal and glass embedded in it that reflect the light and sparkle in the sunlight.

Decorative relief screen: - Pale lilac paint is used on the walls to give the garden a sense of space. It also contrasts with a decorative relief screen that's mounted on the wall opposite the stairs. The screen is custom-built and was inspired by the modern art of Ben Nicholson.

Wave water feature:- A contemporary, stainless steel water feature shaped like a tall wave is used as the central feature in the design, as it can be seen from both areas of the garden. The water cascades gently over the surface reflecting sky and sunlight into the garden.

Galvanized containers: - Galvanized metal containers are used throughout the garden to give extra space for planting. The reflective metal surfaces create additional light into the garden and also complement the plants inside them.

Metal gabions: - Gabions (metal cages) filled with large pebbles and topped with irk wood, form seating areas in the upper garden. They emphasize the contemporary feel of the space and also look good against the architectural foliage of the planting. A rope light threaded through the gabions adds an extra dimension at night.
