Ecological DesignBased on the knowledge and interest of ecological design principle, this comprehensive design project was selected with consideration of regenerative urban context in mind. An urban forest in London Elephant and Castle, it currently under the 1.5billion regeneration project, the site provides a great opportunity to explore the new approach on how ecological design canapply to urban forest regeneration sustainable with cultural identity?

Location: Elephant and Castle, Southwark, London SE17.

Design Rationale: Sustainable Drainage System (SuDS); ecological design; urban agriculture, and

sustainable living systems

Design Concept: Trees as a metaphor for memory

Size: 1.26 hectare

Site ContextOriginally, Elephant and Castle was founded as two prosperous villages, Walworth and Newington, surrounded by market gardens,

The pre-existing 1970’s housing estate- The Heygate Estate once provided approximately 1200 residential units within several apartment buildings of up to 12 stores in height. The Heygate Estate was designed to offer a utopian ideal where communal

under demolition.

Beyond ‘Sustainablity’ The ecological design goes beyond what is ‘sustainable’ aiming not only to maintain status for future generation, but to improveupon the biological integrity of existing conditions. It spires to generate resilience in the face of inevitable future environmentaldisturbances, leading a dynamic stability to both human and non-human communities. Especially, ecological design offers opportunities to enrich biodiversity work with natural process, stimulate natural systems to become self-sustaining and regenerative resources for continued use of human and other species.

Design Goal:The initial aims for the comprehensive design project ‘Eco-city’ strategy, which is about rebuilding cities and towns on ecologicalprinciples for the long term sustainability, cultural vitality and health of earth’s biosphere, example of an inbuilt model of ‘Eco city in Tianjin, China’. The ecological design theory continually drives the design philosophy and goal which is to concern the citizen

and transportation policies and practises, preserving agricultural lands and open space, and retrieving natural habitat (Ecocitybuilders, 2011).

Stormwater collectionSustainable Drainage System design that collect surface water runoff and purify the water to be used on the site.

Cycle routesNew cycle routes through the site, to promote a more safe and convenience environment for cyclist.

Transportation

carriageways and public transport lines

Trees: There are 447 mature Platanus x acerifolia (London plane tree)s on site and forms an ‘Urban Forest’. These are extremely important resource to be kept, not only for their environmental

and new residents. The mature London plane trees will also cast shadow in leaf on the site and reduce should amount shade on the site and reduce light levels, therefore the removal of some of the mature trees of the site to introduce more light to the site as well as adding other species tree to improve ecological values.

User groups:A mixture of user groups that need to be considered throughout

design, i.e. economic growth, social connection and health and wellbeing environment. The heavy usage of the site will affect the plant selections and increase the maintenance loads.

“Trees, our mute companions,looming through the winter mist

from the side of the road, lit for a momentin passing by the car’s headlamps:Ash and Oak, Chestnutand Yew;

witnesses, huge mildbeings who suffer the consequence of

sharing our planet and cannot move away from any evil we subject them to,

whose slient absolution hides the scars of our sins, who always forgive-yet still assumethe attributes of judges, not victims”.

Fainlight’s poem interpret trees as wise and trusty living organisms, they witness landscapes

and people growing and changing through time. The inspirational concept of this project is

using ‘The Tree’ as a metaphor to represent past, present and future. The tree illustrates

time and space, changing with the seasons and as an indicator of climate. They make a

contribution to people, environment and landscape character. The existing plane trees are

strongly linked with local people who have grown alongside these trees, and are part of

their memory. By enhancing the existing tree structure to become an ecologically diverse

urban forest where a range of trees and other plant layers combine with water.

climate and as a working landscape, integrated with a Sustainable Drainage System of

of varying scale and character accommodate a range of uses and activities that will be

attractive through the changing seasons. Any trees removed from the site will be reused

on the site, as seats or sculptural elements, to prolong the tree’s longevity in a different

way.

Form Development:

The forms continuously developing from the concept

-’Tree are essence of this landscape’. Trees planted in

Heygate Estate in 1970s, was intended to form as a tree

communities, which purify the air, noise and pollutions.

However due to the demolition of this regeneration project,

many trees are due to be removed to allow the residential

buildings to be built. The existing plane trees are strongly

linked with local people who have grown alongside these

trees, and are part of their memory. Reconnecting the tree

communities by creating linkage between trees, frame view

and focal points etc.

Project Overview

Phase 2: Hard Landscape Plan

Project: Elephant and Castle Urban Forest

Client: Lend Lease (Developer)

Location: Heygate Estate, Elephant and Castle, Southwark

Reference Number: W202012

Landscape Consultant: Ecoscape Studio

The site dominated by roads that carry a lot of traffic from Europe

and South London into the city centre, the site has designed to adapt

SuDs (Sustainable urban Drainage system) to collect surface runoff

and reuse the water on the site. Mixed use residential and commercial

blocks have also proposed around the site thus consideration towards

the suitability and functionality of materials are significant in both hard

and soft landscaped areas. The overall material selection criteria will

base on the hard wearing and long lasting, tolerance heavy pedestrian and

cyclist usage, low maintenance, user and environmental friendly , as well

as aesthetically pleasing.

Elephant and Castle urban forest ‘Phase 2 detailed plan’ (see figure

1),shows the sections lines (Figure 2 &3) that the three construction

Vertical Detail

General Applications:

Design Context:

The general application of the vertical water rill, determined the materials and

components that create the visual impact and safe to be install on the site. It

will look at the materials that can complement the best for the design. It usually

built as rigid structure as solid architecture pool in reinforced concrete(Figure

4) fibreglass reinforced plastic, natural stone, steel and masonry.

Concrete:

Concrete is the most commonly used material used in the construction of many

of the water features (figure 5). The concrete usually waterproofed mainly

forms many of the features bases which house the features workings such as

the pumps. Concrete is the best material for constructing the bases of the

features due to its strength and durability. It can be formed into a variety of

different shapes and sizes without losing it strength. Concrete itself is long

lasting a will outlive the feature itself.

The design of the curved water rill with waterfall aims to create a formal feature

that reflects the surrounding urban architectural environment. The water

feature also designed to incorporate with SuDs system on the site, where rain

and surface water will be collected and transport the central retention pond

via swales, and release the water or celebrate this resource in a high aesthetic

and practical way.

Safety Consideration:

The design also considered the use of material, finishes and incorporation of

ambient lighting sources, to meet both functional and conceptual purpose

(figure 6,7). The safety contextual factors have also considered, the feature

can be utilised both during the day and the evening. It used medium to large

natural rocks next to the edge of the rill, which act as both visual and physical

barriers.

Design Criteria

Aesthetics: designed to maximise the visual effect of the flowing water, incorporate

lighting system to create a visual impact and encourage the site usage during night

time. Colour selections of material are design to create contrast and harmony to the

overall design scheme (figure 8,9).

Function: it utilised as part of the SuDs system on the site, where water release

into the retention pond and discharge the overflow of the water back to water rill. It

retained part of the edge of the retention pond. It allow people to view the feature from

different areas, and accessible for people to interact with the water with care.

Technical: Design requires the corporation on pump system where water will source

from the underground water storage to supply consistent flows of water. Lighting

installation will also be placed for its high aesthetic value.

Environmental: should be cause no pollution to the water and biodiversity or surrounding

landscape.

Durability: the selection of materials is hardwearing and durable with an extensive

lifespan.

Cost Effectiveness: a designed to be build curved reinforced concrete rill by Hy-Ten, Uk,

where high quality material will be used and the cost will be higher for it’s value.

General Application

Design Context:

The pedestrian bridges are particularly eye-catching elements that they can

enhance the landscape characters. The general application of pedestrian bridge

built for pedestrians and cyclists in or around an open public space significantly

influence it’s appearance, the materials for the structure are usually built from

timber, steel, cast iron, concrete, glass, bronze and cut stone; and different

type of bridge structure are design to meet it’s loading capacity and usage

rates (figure 10).

The case study (figure 11): The Sackler Crossing that the material- granite

cut stone, the durability, high quality finish, easy maintenance and the great

aesthetic value, is achieving a high standard bridge design. The chosen materials

for this pedestrian bridge are influence by it, for its outstanding design and

durability.

The design form of the bridge is replicating the pre-existing London plane tree

arrangement, where the curved bridge reclaimed the ethic of the space (figure

13). The design consideration of this pedestrian bridge is based on its visual

impression with surrounding landscape; the loading capacity and its soil type

on the site; the weight of traffic and usage.

The bridge is designed as cantilever bridge, that build over the SuDS retention

pond with height of less than 1.5 meter, where provides access from market

square and retail area to the floral carpet. It is an important transition element

of the site which pushes people from the busy atmosphere, to a space people

can sit down, relax and connect to nature. Therefore the materials selection for

the bridge is highly durable, visually pleasant and efficiently functions (figure

12).

Design Criteria

Function: High traffic pedestrian bridge. No vehicular traffic. Should enhance

landscape and landscape views. The bridge is design to be user friendly for

all.

Environmental: Should not cause any pollution to the water or surrounding

landscape to prevent plant/ animal deaths.

Technical: Design must appear minimalistic; main beams, abut¬ments and

fixings should not be visually apparent. Lighting needs to be incorporated

for use at night.

Cost Effectiveness: The construction of the design will be build and

construct on the site via bridge engineer- Balfour Beatty and Buro Happold.

Therefore the bridge will be cost higher than others, but with higher quality

structure finish.

Durability: The design is to be a contemporary landmark that engages the

past and future of the site, therefore the materials must be durable for an

extensive period of time.

Aesthetics: the outlook of the bridge are simple, clean, crisp aesthetic.

Bronze uprights have reflective qualities that are similar to water in

sunglight. it has a repetative uniform materials are legible. Coherent

design allows the structure to be read clearly within the landscape. Simple

repetition of elements allows a different visual story to be read from various

angles. Material choice is high quality and very contemporary. (figure 14).Figure 14: The bridge bird side view to the site with surrounding context. Source: Li, 2012.

General Application

Design Context:

The planting in the landscape is adding the excitement and atmosphere to the

environment, and it’s providing significant environmental value to our planet.

Plant health is affected by various different factors. The most significant of

these are the availability of nutrients, soil conditions, climatic condition, and

competition pressures arising between different plant species (Zimmermann,

2008).

Forest planting

Forest planting is groups of plants that tolerant low light, nutrients level and

plant competition. Succession is part of the establishment and development

of plant communities that lead to the four layers of plant selections- The

emergent layer; the Canopy; the understory and the forest floor (figure 15,

16,17).

The existing London planes trees on the site has form as forest patches that

designed to be kept and extensively regenerate a new forest to improve the

ecological value and biodiversity, by adding more native plants and wildlife

beneficial plants.

The selection of planting is established upon the suitability, architectural

forms, colour interests and ecological benefit. The arrangement of the plants

should also be based on forest layer system, which it will present a overall

naturalistic forest succession scheme. The soil of the site is heavy clay with

PH 7, which it should be loosened by adding sand or compost and the topsoil

should be improved by adding humus.

Design Criteria

Function: Sustainable plant communities should minimise the plant competition

within the space. It acts as buffer from traffic noise from surroundings. It provides a

more pleasant space for people to enjoy.

Environmental: the soft landscape contributes immense amount of benefit to the

urban environment, it reduce the pollution, provide food for birds and improved urban

green infrastructure.

Technical: SuDS system that takes the excess water away and transport into the

retention and reuse to irrigated the plants on the site.

Cost Effectiveness: local plant nursery supply where plants should takes less time

to establish than plants source from foreign nation. It also helps the local business

growth and reduces the transportation cost for the planting

Durability: All selected plants should be hardy and quick to established to the site,

plants should be take care for the first planting year (to the maintenance plan) in order

to ensure the establishment of the plants are successful.

Aesthetics: the seasonal colour interest plants provides year around interest to

the overall scheme. The evergreen architecture form plants (i.e. Ferns and Evergreen

shrubs) giving the consist look to the forest throughout.

Notes:

Depend on the size of the pot, all planting bed

should be prepared with twice the depth of the container

pot and 2/3 of the spread for the herbaceous and shrubs.

The tree pit should be prepared twice the spread

on the ground, and stake support is required. The tree

truck should be 1.3mter above the ground.

Conclusion Reference

This report demonstrates some complex construction details range from hard

landscaping materials to planting materials. The first detailed section shows the

transition between land and water, how water edge is retained for heavy pedestrian

use. Additional services i.e. waters pump, lightings installation and how the design

prevents the area from flood risk. The second detailed shows a cantilever bridge

construction of the site and research from other case studies on how materials can

complement the design idea in more practical way. The third section soft landscape

detailing shows the importance of plant selection of their conditions (including soil,

climatic condition, ph and hardiness), as well as how the initial preparation should

be carry out to ensure a good plant health from start. Overall, to understand the

construction detailing for each design should be considered at very early stage, in

order to test the physic issue within the design.
