Objective of Study To prepare a landscape proposal for an area equivalent to a 10m x

10m within Taylors University Lakeside Campus

The Site

The site is a roof terrace located on the 7th Floor of Block E

View of Block E from Commercial Block North

The Site Analysis

• Area to landscape - approximately 10 m x 6.8 m with a 3.2 m wall on one side• Location – the open terrace

of level 7 of Block E• Accessibility – via walkway

corridor and staircase• Current use – vacant roof

The Existing SiteCurrently the site is a vacant roof terrace.There is a 1m height metal railing along the perimeter of the terrace.There is also a perimeter scupper drain and a PVC pipe along its perimeter.There are scattered chairs at the terrace (students have been using for relaxing).There are several surface crack lines on the concrete floor slab

Flat concrete slab should be able to cater for the walkway pavements and small planter boxes but perhaps not heavy loads such as water ponds.

The Views From Site

Pleasant panoramic views from Level 7 site of commercial block and campus lake

The Views From Site

The major strength of the site is its breathtaking high views of the campus lake and elegant buildings.A welcome site indeed after an especially stressful class.

Site Opportunities and Challenges

• The site has an excellent high views of the campus lake and buildings.• It is located at the end of the corridor of Level 7. Level 7 consists

of classrooms which need a quiet conducive environment.• As such, the site is suitable to be utilised as a quiet passive

recreation area. Perhaps as a place to enjoy the view, de-stress after heavy lectures or a place to chill. There can be also quiet study or waiting areas in between classes or just a place to meditate and reflect on events of the day. • Besides its usage and views, the landscape proposal has to take

into account safety, comfort - the need to shade from the afternoon sun, planting materials that can be accommodated by the existing floor slab, drainage and maintenance requirements.

Page 11: Landscape roof terrace

11

Design Criteria

• Spatial Planning- A quiet place for students to hang out, chill and de-stress.• Low-noise generated so as not to disturb classrooms• Safe Place - Railing, floor and wall.• Comfortable Space- Thermal comfort, tree shade and breeze.• Attractive Roof Terrace- green plants, aesthetically pleasing.• Social interaction, cosy corner and chill out corner.• Quiet Corner- To relax, study, unwind and have a quiet time.• Green Initiatives- Planting at 7th level, to provide shade, to cool

wall/roof terrace, to buffer the heat from afternoon sun at the full glass wall, plants to soften hard wall, solar lighting.• Ease of maintenance- plant, cleanliness, non obstructed drainage flow,

reduce need for pruning and grass cutting.

Page 12: Landscape roof terrace

12

Design Elements

The following design elements are proposed:-• The entrance statement to the landscape deck – proposed as

the “Zen Deck” due to its need to be quiet, passive area to enjoy the breathtaking views.• The Viewing Deck to enjoy views and relax.• The Chill Zone with a gazebo and seating area for meditation

and reflection (basically to unwind).• The Quiet Zone with roof canopy and seating area for study.• Planting materials for shade, softening effects, screening of

the stairwell glass wall. Flowering plants at planter boxes to provide colour and aesthetics to an otherwise stressful campus day.

Page 13: Landscape roof terrace

13

Design Elements (contd.)

• Planter boxes to contain soil and planting materials which can be accommodated by the existing roof slab structure. Creeper plants on trellis to screen and cool the glass wall at the staircase.• LED lighting, solar lighting to minimise wiring.• Recycling bins.• Adequate floor drainage and downpipes to avoid ponding at floor

slab.• Outdoor seats which are durable and weather-proof.• Walkway pavements and pavement floors at Viewing and Chill

Zones which are non-slip and durable.• Raised timber floors at Quiet Study Area to demarcate the zones.

The trellis at the study area performs functions to absorb the noise, screen the glass wall behind from the afternoon sun, as well as to soften the hard surrounding building and provide colour to

the environment.

on this small tree. - Planted in light shade in a rich, well-drained

soil with regular watering, the Mountain Rose will grow slowly at 3 feet in height.

- In its native habitat, it is an understory shrub and must have protection from strong wind. New growth is purplish and pendent, turning green upon maturing, providing an interesting focal point.

- Its bright flowers provide an excellent colour accent.

- It is neither drought nor salt tolerant. - They are also nitrogen fixers.

Hibiscus rosa-sinensisCommon Red Hibiscus HybridsMalvaceae (Hibiscus Family)- Planted in full sun in a good friable soil and

watered moderately. - They are quite wind resistant and will

tolerate considerable salt air.- They are somewhat drought tolerant but

will defoliate.- Regular feeding with a well-balanced

fertiliser will promote strong growth and abundant flowering.

Bougainvillea GlabraPaperflowerNyctaginaceae (Bougainvillea Family)- Tiny white flowers usually appear in clusters

surrounded by colourful papery bracts, hence the name paperflower.

- The leaves are dark green, variable in shape.- Heat and drought tolerant.- It is easily propagated by cuttings. - It needs full sunlight, warm weather and

drained soil to flower well.

The Planting PlanProposed planting materials – Trellis

Ipomoea purpureaMorning GloryConvolvulaceae (Morning Glory Family)- A highly ornamental climber, the climber

produces clusters of large purple flowers along its arching branches. It is drought, heat, and wind tolerant.

- Like all morning glories the plant entwines itself around structures, growing to a height of 2–3 m tall.

- The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types.

- It is naturalized throughout warm temperate and subtropical regions of the world.

- Although it is often considered a noxious weed, it is also grown for its beautiful purple and white flowers and has many cultivars.

- It makes a striking floral accent.

The Maintenance PlanThe Cost Plan provides for maintenance by the contractor of the completed planting for a period of 12 months. The maintenance include watering, weeding, pruning, fertilising, spraying and clearing of unnecessary growth etc, and any other horticultural management as deemed necessary for the proper growth of plants.

1. Fertiliser programme for trees and shrubs• Compound fertiliser (NPK : 15:15:15)• Application rate : 150 gram/tree/every month

100 gram/shrub/every month

From the end of planting until the end of maintenance period, the contractor is required to replace dead, stolen and dying plants or those severely damaged by pests or diseases to the current sizes of the dead, stolen or dying plants and true to type at the contractor’s own costs.

After the expiry of the 12 months maintenance period, the fertiliser programme will be carried out by the university’s maintenance team. It is important for the maintenance team to also prune the planting materials, clean the pavements and check all sub-soil drainage and downpipes to ensure no blockage. As such, frequent (3 times a week) cleaning of leaves is important.

Perhaps, sponsorship can be sourced for the construction as well as maintenance of the project. Sponsors such as paint companies may like to carry out their CSR effort at the university.

Conclusion

The “Zen Deck” landscape proposal was derived after analysis of the site and its surroundings, and the need for use of the space. It is currently a vacant roof terrace which has potential to be fully utilised as a passive recreation zone.

The proposal seeks to take advantage of the excellent view of the lake from the site.

The main components of the project are the Entrance Statement, the Walkway, the View Deck, the Chill Zone and the Quiet Zone. These zones all share the enjoyment of the proposed ornamental plants which will not only beautify and soften the building, but also provide relief and help to de-stress students from intense academic activities. The area will also accommodate students who wish to catch up on some reading in between classes and also serves as a meeting area.

The selection of plant materials and street furniture caters for both aesthetics and function.

The Zen Deck will be a major landmark for the campus and should be implemented as it will bring benefits to both students and management alike at an affordable cost.
