01 The Library Courtyard - Site Analysis and Model Exploration Problems of the existing library courtyard: • poor access from the east to the west • car parking space share the same place • lack of interest • too much hard surface • limited space
y brar nk Li a B ern West
New Design: The Library Courtyard is refurbished with a modern approach that makes the site neat and simple. The design concept was drawn from the physical appearance of the plant and animal cells which are rectangular and round respectively. Since the space itself is relatively small, the design tactic was to create little pocket spaces within the limited space. Sculptures will be placed in the redesigned garden as an extension of the exhibition space in the Western Bank Library. The eastern boundary is marked by a big mass of sculptural platform and this hardiness is contrasted by the vast extent of soft surface towards the western side.

Design Statement: The Garden addresses the adverse conditions of smog around the globe, such as China, India and Iran. It features three areas that offer a breadth of experiences and perspectives. Visitors will first pass through a walkway that encloses a glass house. On the walkway, visitors as outsiders can have a sit and observe the appearance and fading out of silhouettes through the glass wall. When ones move their steps into the glass house, multiple sensations will be stimulated: the poor visibility and mild irritation in the dense vapours, and the gasping noise. As the journey of exploration continues, ones will enter the final stage in which an open, confined space contains a tree standing on a grassed mound. In this narrow space, people will naturally look up to the skies and the canopy of the tree while ones can once again take a breath comfortably. The process of experience would like to inquire how important fresh air is and how much unpolluted space where people can breathe easily is left as urbanisation goes along.

Both external glass and internal glass are clear and toughened and has a thickness of 80mm and 60mm respectively. The cavity in between two glasses is 20mm wide. It helps insulate the enclosed environment from the surrounding, especially for noise.
The Flow of Textures Textures of paving/ground are manipulated as a means to express the moods of different areas of the Garden. The exterior walkway depicts the neutral quality of perspective as an outsider that observes the situation in the indoor environment. Therefore, light grey concrete with fairly smooth surface is used to express the neutrality of this space.

When people move into the glass house, ones will feel the coarse texture underneath their steps. That sensation is to represent the particulates in the smog that people prone to inspire. Practically, it also increases the friction of floor, so as to avoid people from falling down onto a potentially slippery floor as water vapours condense. After a while of exploration inside the misty house, one will enter the central green where the hard paving is replaced with lawn which is soft enough that people can enjoy sitting and lying on. This relaxing experience through texture is meant to be a depiction of the goodness of natural environment.

03 Planting Design for St. George’s Church
01
03 The Library Courtyard
Conversation between the Past and the Present The renovation project runs from Favell Road (west of Information Commons) to a section of Mappin Street to the west of Department of Civil and Structural Engineering building. The site exhibits a transition of a historical to contemporary atmosphere which has informed the design concept of Conversation between the Past and the Present. Surrounding the St. George’s Church are some big trees, e.g. Tilia spp. and Aesculus hippocastanum, and antique buildings which seemingly speaks softly how we are associated with the past. As one moves towards the Information Commons, a burst of modern, colourful and geometric architecture will be experienced. Three Prunus trees identified in the St. George’s Church area during site analysis have inspired the planting strategy of the project site. One of them has reached its mature size and two were planted in memorial of someone’s beloved in 1997. These cherry trees themselves and their pale colours are interpreted as vocabularies of the past that communicate with the present. Some twenty trees of Prunus spp. will be planted in the church area that will mildly give a bloom of pink in winter and spring. Specimen Prunus trees will also be planted intermittently in different spaces across the whole site to enhance linkage, and also as symbolism of a dialogue between the past and us. The trend of the planting from “the past to the present” will be from naturalistic and pale-coloured to more geometric and colourful. The feelings of these spaces will change along the trend gradually from relaxing to more vibrant as well. A retrofit approach is taken to the planting design in the Church area. The traditional herbaceous border with a modern twist is applied to maintain the relevancy to modern times. More lawn areas are kept to the east side, which is an east-facing, gentle slope, as the site analysis revealed that this is a place more frequently used for lunch and unwinding. The simplicity and subtlety of this detailed planting are mainly expressed by a single species, fine-textured, densely planted groundcover Vinca minor f. alba ‘Gertrude Jekyll’ and pale colours appearing in different seasons. The groundcover is also a crucial medium for weed control when established. Deliberately a limited number of species (16 nos.) are selected to create a rhythm of naturalistic appeal to avoid overwhelming visitors with busy compositions of colours and forms. Vertical elements are emphasised by planting Matteuccia struthiopteris in shady area and Calamagrostis × acutiflora ‘Karl Foerster’ in sunnier area. In the end, the greater vertical elements formed by the existing Prunus trees and the newly planted Prunus trees will be another representation of a Conversation between the Past and the Present.

This planting design aims at creating a naturalistic visual display, so there is much room to tolerate changes as plants grow (i.e. fairly low maintenance is required). Autumn and winter interest is mainly aroused by the beautiful structure of withered plant parts, e.g. seed heads of Sedum ‘Herbstfreude’, stems of Matteuccia struthiopteris and Calamagrostis × acutiflora ‘Karl Foerster’. In spring and summer, the yellow, pink and purple colours are the major interest, e.g. flowers of Lupinus arboreus, Prunus spp. and Acanthus spinosus. Year-round interest is kept by having evergreen species and some even have colourful foliage, e.g. Heucherella ‘Sweet Tea’. The huge, short-lived Geranium maderense also plays a major role in providing year-round interest with its big and lobed leaves, red stems and almost year-round stunning flowers. The different heights of mound-like, e.g. Geranium spp. and Lupinus arboreus are also meant to give a vertical complexity throughout the year. A green carpet of groundcover will be made of the evergreen Vinca minor f. alba ‘Gertrude Jekyll’. This is intended to be the major weed suppressor of the planting scheme, so a higher spacing is given.

There are no major maintenance tasks from mid-spring to mid-winter. Until late winter or early spring, the herbaceous which are Acanthus spinosus, Calamagrostis × acutiflora ‘Karl Foerster’, Geranium phaeum ‘Samobor’ and Matteuccia struthiopteris and Sedum ‘Herbstfreude’ should be cut back. No cutting should normally be carried out in autumn, so as to keep the magnificent structures of the withered plant parts. After cutting back, the bare soil should be covered by a 40mm of coarse composted bark till V. minor f. alba ‘Gertrude Jekyll’ has completely covered the soil. The bare soil after cut-back should be less in five years’ time, so the amount of mulch needed should also be less. Species are generally planted in high density in order to give an instant effect. If some spread out from the blocks, it will still be in line with the design aesthetics unless some outcompete too much the others that ruins seriously the integrity of the planting design, i.e. plants blocks can very hardly be recognised. Geranium macrorrhizum ‘Album’ and Geranium phaeum ‘Samobor’ should be worth more attention on their spreading rates and remove the invading edge when necessary (dividing the oversized blocks could be considered). V. minor f. alba ‘Gertrude Jekyll’ should be allowed to spread out as it is the sole groundcover. It is a desirable condition if it spreads across the planting blocks because its short leaves are visually insignificant when they are underneath other planting blocks, but it does avoid bare soil covered by those deciduous in early spring. However, the groundcover should NOT be allowed to spread out too much to the adjacent lawn. A small coverage of grass species and weeds within the planting is acceptable, but they altogether should not cover more than 20% of the planting area. If so, manual removal of these weeds, including their root systems, from the soil before their fruiting seasons is recommended, which is generally in summer. The outgrowth of grass species and weeds is expected to be less and less an issue as the groundcover is establishing. Removing litters and shed leaves is recommended to take place annually along with cutting back of the mentioned herbaceous plants. The designer is happy to have an on-site inspection and give advice in the 2nd and 5th year mid-winter.

Design Statement

The regeneration plan of the Piccadilly district in Manchester is initiated by the proposed HS2 station to the north of the existing one. The City Council has requested a boulevard which is going to be dramatic and give an identity of the City to the tourists upon arrival, yet in the original proposal of the boulevard has only rows of trees and benches that unconvincingly would meet the wish of the City Council.

B A
The counter design proposal was inspired by the fluidity pattern of trees in the Medlock Valley that creates a variety of spatial qualities. The design intention is to inject the dynamics into the future city centre. There will be a gradual transition of urban formal green space to a more natural vibe through manipulation of different forms of trees, e.g. tall, wide spread and through variation of tree densities. This design also aims at lowering the flood risk posed by River Medlock and providing better pedestrian experience.

Heavy Traffic in the Boulevard Lack of Direct Route to High Density Housing Development
Lack of Cultural Uses It is believed that this will reduce the vibrancy and diversity of the regeneration district.
This will be inconvenient for the residents of that housing estate.
Cultural Buildings and Amphitheatre Proposed
Diagonal Route Provided
The functions of these facilities will be mutually reinforced. The public space will then be transformed to a major space for cultural activities and thus the function of the nearby se ectio ctio ct ion of of the the e boulevard bou oule levv le section will be affected.
In addition to the access to the housing development, the pedestrian circulation towards the northeast of the regeneration area will also be enhanced. This layout of route system will strengthen the role of the cultural area as a central public space which is just outside an entrance of the future train station.
The currently proposed boulevard is very much oriented for motorised traffic which will very hardly provide an enjoyable experience for the pedestrians . Remain Part of the Traffic in London Road This will reduce the motorised traffic in the boulevard, so that a better space for pedestrians can be created.

5. Water Management Lack Drama
Lack Water Sensitive Design
The boulevard has only two rows of trees and benches. There is no detail of how drama is created through these features.
The Mayfield development (the southern side of the train station) has proposed a central green space that provides a flooding zone, but within the Piccadilly regeneration area has no proposal regarding of this issue.
Richer Sensational Experience A great variety of spaces will be created through planting design, e.g. from more formal to more casual; from open to more intimate.
Flood Risk Remediation A large portion of the surface within the boulevard will be permeable. In front of the western entrance, there is a rain garden feature and by the lobe of the River Medlock in the new park, there will be wet meadow area which will allow flooding.
