01. Stage 1 : Vision and Concept
In response to the issues in the housing market, Stage 1 develops the new proposal for housing in Philadelphia, Sheffield. Based on the site analysis, the process details the vision and concept and explores the various strategic documents and policies linked with the successful case studies.
1.1. CURRENT ISSUES IN HOUSING a. Issues
b. Context
Across the country, there are more than 27 million homes, but many more are needed due to population growth (Kerley, 2021). The following are the current main housing problems as summarised by Crisis UK (2022):
The UK receives approximately 23,000 applications for asylum every year (Figure 1.1). However, two-thirds of them are placed in informal settlements and stay in refugee camps in the short-term (ICMC, 2012). Affordable housing is one of the most complex issues for them and it is related to the tight housing markets and rising housing prices. Asylum seekers tend to be accommodated in temporal properties for which there is low demand, where there are no opportunities for jobs and the property is overcrowded (Housing Europe Observatory, 2019).
Unaffordable rent
A lack of new houses being built compared to the rise in the population
In the smaller context, Sheffield's population is growing and expected to hit 600,000 by 2023 (Sheffield City Council, 2013). According to the latest population estimates, refugees make up seven of every 10,000 Sheffield residents and the majority are housed in rental accommodation (Migration Yorkshire, 2020). After the initial provision of temporary housing, the focus should be on long-term accommodation and meaningful inclusion in terms of the cultural and regional aspects (Housing Europe Observatory, 2019).
A lack of good quality housing
Besides these general structural problems in the housing market, some groups of people encounter various other obstacles and face difficulties in housing. Several reports have highlighted the challenges that refugees face in acquiring affordable housing in the UK (Housing Europe Observatory, 2019). [Figure 1-1] Asylum applications in the UK

"We don't have refugee crisis. We have a housing crisis" (Anonymous, 2016:online).
"I just want to feel safe. I want to have a healthy baby who can grow happily, but I feel like nobody cares. Nobody wants to help" (Omeimah, 2020:online).
1.2. VISION AND CONCEPT Mindmap : Strategy for the Refugees
VISION: 'We Philadelphia' is designed to devleop a long-standing relationship with multi-generational refugees and ensure their inclusion in our society. Based on the co-housing scheme and references to Soft City (2019), the three key principles for livable and sustainable housing are as follows:
1. Connecting to the community •Introducing a 'local buddy' system in a co-housing setting (UIA, 2019) •Introducing a 'self-management' system to promote residents' participation (Startblok, 2022) •Designing walk-up-height buildings to ecreate a connection between the ground and upper floors (Sim, 2019)
2. Diversity of housing and open spaces •Providing different sizes and typologies of buildings to support various activities •Providing adaptable spaces to support a bottom-up approach •Providing different gradients of outdoor spaces for social interaction •Connecting the outdoor space to the indoor space
3. Climate resilience •Improving the River Don area with redeveloped social spaces •Generating spaces to accommodate soft landscaping and apply SuDS scheme •Providing a sustainable transport network (cycle lane/street) to reduce car use

The former industrial site of Kelham Island has been approved for a number of residential developments in recent years (Sheffield City Council, 2008). These new developments respect the existing history and distinctive character of the area. In a wider context, in addition to the site, the riverside location offers picturesque tranquillity combined with vibrant industrial and urban culture containing offices, apartments and pubs.

•Distinctive red brick buildings. •Buildings that represent the history (ex. Green Lane Work, Kelham Island Brewery and Kelham Island Museum) •There are not only lots of manufacturers but also local pubs and restaurants. •Street arts •A mixed-use area, dominated by a growing residential community (ex. Little Kelham) with some commercial uses (Sheffield City Council, 2008).
•Location : Philadelphia, Rutland Way, Sheffield, S3 8DG •Context : The site is located at the edge of the city centre, Kelham Riverside, and surrounded by Peninstone Rd, Rutland Rd and the River Don. Currently, the site itself is an empty brownfield site with industrial remnants and unmanaged vegetation.

•The bus stops and cycling lanes on the main road which directly connected to the site are poorly managed. Improvements such as benches and vegetation are required.
1.5. LITERATURE REVIEW a. Co-housing
b. CURANT Project and Self-management Strategy
[Figure 1-8] CURANT project Many actors of the issue "refugee and migrant inclusion and integration in welcoming societies" [Figure 1-6&7] Illustrations of co-housing community: Startblok (left) and Marmalade Lane (right)
believe that co-housing scheme would be an ideal way of living together in our cities (UIA, 2019). To deliver socially sustainable housing, Based on the co-housing scheme, "We Philadelphia" project was
"The original Cohousing was designed for two main purposes: to increase the quality of cohousers' life and to lessen the burden of everyday life, while increasing freetime at home" (Lietaert, 2009, p.578).
inspired by two refugee integration strategies: CURANT and Self management.
CURANT
-Key principles (Pan et al., 2018) Physical Design
Social Design
•Each household has their front doors. •Homes are grouped around and overlook common spaces (casual surveillance). •The common house
•Four fundamental characteristics: 1) weekly shared meals; 2) regular membership meetings; 3) resources sharing; 4) diverse membership (e.g. age, religion and household type).
-Design considerations (Pan et al., 2018) •The site plan and community layout •Car-free living space •A child-friendly environment •The transitional space between private and common space •Location of the common house
•Transitions between community and surrounding neighbourhood •The design of privated units •Choices of housing models •Accommodating future changes (Flexible architecture and Lifetime Homes)
Self-management
- Aims and objectives To support young refugees the ages of 17 and 22 years by providing a support programme that prepares them for independent living and encourage their participation in Belgian society.
- Aims and objectives To create a community by letting residents (young refugees and local residents from 18-27 years of age) organise and manage the project themselves.
- Innovative aspects •Decent & affordable housing
- Innovative aspects •Both refugees and Dutch tenants share a sense
•Cohabitation with a local flatmate ("buddy")
of direct ownership of the project
(UIA, 2019)
•Active inclusion in organisational roles (Czischke, 2018)

d. Bottom-up Process
c. Refugee Integration through Co-housing
[Figure 1-10&11] Deisgn worskhop and idealised bottom-up process [Figure 1-9] Organisation of the Startblok self-management
Recently, a more sustainable approach in urban living has been adopted by a variety of communitybased initiatives (Deffner et al., 2021). The bottom-up approach allows community involvement in decision making, enabling communities to decide what they need in terms of shaping their homes and living environments (Sylva, 2017). This process can be achieved through user-led design of their own units, which takes place early in the design and building phase. In addition, having control over the design also promotes a sense of responsibility, leading to a higher level of user buy-in (Groeneveld, 2018).
In the UK, the enforced extended period of stay for asylum seekers in their designated accommodation and the insecurity they experience while waiting the outcome of their application is a negative starting point. Moreover, as new arrivals, they may lack cultural knowledge, skills and language to help them intagrate. However, UK refugee policies focus mainly on tangible outcomes such as housing, work and education (Housing Europe Observatory, 2019). In this regard, Czischke (2018) points out that integration can be promoted through social connections as outcomes follwing from the co-housing: social bonds, social bridges and social links.
This method can also be applied to mobility sharing schemes in a co-housing setting. Mobility sharing, such as neigbourhood-based car sharing, cargo bike sharing or public transport ticket sharing, can be both easier and more flexible. The key drivers for adopting mobility sharing are reducing the amount of parking space needed on the property and for environmental sustainability (Deffner et al., 2021).
•age-relate/intergenerational bonding Social Bonds
•mixing people from the same and other cultural backgrounds, which can be achieved by leveraging the 50/50 principle
"It was great to be involved with the whole journey of design and development" (Wright, resident in Marmalade Lane, 2021:online).
•the 50/50 principle serves to prevent the drift over time towards hoSocial Bridges

2.2. DESIGN PROCESS [Design principle] Edges and Spaces : Degree of Enclosure
a. Enclosure on Three + Semi-enclosure
The built form can define spaces (Sim, 2019). Considering enclosure with focus, edges and movement, the following are the building block options: Building blocks
b. Enclosure on Three + Outbuilding The outbuilding divides the space into smaller fractals.
Making houses layout spread will increase access to river, creating little street activities.
Spaces

1. Enclosure on two
1) Open courtyard with a view to the outside 2) Accessible 3 Easy movement (courtyard ~ street) 4) Loose thresholds can be added
The entrances near the bus stops will make the site more accissible.
2. Enclosure on three
1) Focus 2) More restricted views 3) Permeable edges can be added

5. Outbuilding
1) Double courtyard (private and semi-public) 2) Space variation
DESIGN APPROACH
DESIGN APPROACH •Using the 'focus' point to create a courtyard. •To maximise the access to the riverside, movement focused semi-enclosure layout was designed, creating little alleys. STRENGTHS •Access points are near the bus stops. •A direct journey from Rutland Rd to River Don. •Variations in 'enclosure' can meet different uses of space. •Taller buildings on the edge help screen overbearing adjacent building (Heise, 2021).
WEAKNESSES •The plaza is not acting as a main communal space. •Little connection between outdoors and indoors. •The location of the communal building is not reasonable to attract residents. •Semi-enclosure layout seems disconnected compared to other residential blocks. •Although there's a link between Rutland Rd and the riverside, the feelings are different (semi-public and semi-private) which is inefficient to increase the riverside usage.
18
•Connecting existing building (communal building) and the plaza. •Using building heights to create a sense of cohesion and stabaility in layout.
STRENGTHS •A positioning of the outbuilding visually divides the courtyard into smaller spaces (double-courtyard), creating edges and bringing intimacy to the spaces (Sim, 2019). •Ancillary spaces are useful in accommodating change, including densification (Sim, 2019). •Secure edges in terms of the wider context.
WEAKNESSES •Residents may feel being treated discriminatingly because only a few communities have outbuilding layout. •The purpose of the outbuilding in this scheme is ambiguous. Is it a communal building or a shop? •The boundary of the each community is unclear •Communities cannot be organised well. •Residential building as an outbuilding is not reasonable as the residents might feel like they are being watched.
*Numbers represent the height of the builidings.
c. Enclosure on Four + Semi-enclosure
d. Enclosure on Three + Landmarks
The layout will encourage street activities.
A communal building in the middle will act well as a main hub.
b. Outbuilding
The courtyard can have two different atmospheres.
DESIGN APPROACH
•Devleoping movement focused layout to activate the streets. •Activating the plaza area with the efficient layout WEAKNESSES •Unclear boudaires •Too much movement •The variety of layout may hinder the community from gathering •The open edge of the whole site may not be secure for residents •Only one residential block has a courtyard •What's the purpose of keeping two existing buildings? Are they for the whole community?
•Using building edges to create smaller spaces. •To create more vibrant outdoor spaces, density was increased while keeping the ideal human scale, which is no higher than six stories (Sim, 2019). •Plaza as a focal point in the wider context. STRENGTHS •Variations in height for the buiding at the site edge can maximise solar potential to the courtyard. •A wider connection of spaces with a communal building and the plaza. •A good use of different housing typoligies with its cohesive layout. •The plaza can be used as a place of movement (Sim, 2019).
a. Semi-enclosure and the riverside
Low-rise terraced houses provide a glimpse to the river through little streets.
Site edge increased by sub-dividing original site into smaller blocks (Sim, 2019).
DESIGN APPROACH
STRENGTHS •Communal building in the centre is more accessible and potential to engage people. •The location of the plaza is reasonable to gather people •Variation of the layout and housing types will meet the residents' different needs. •Active streets
Cohesive building forms can create a sense of identity in the community.
[Key Features depending on the layout]
WEAKNESSES •Considering the gradient across public to private, different treatments of the thresholds are required •Additional bin collections in accessible spot might be needed. •Careful selection of vegetation strategy in different spaces might be needed.
c. Courtyard
The building edge provides secure boundaries and enclosed space.
d. Landmark
The tallest buildings around the corner of the edge can act as a 'landmark'. 19

2.4. MASTERPLAN ANATOMY a. Housing Typologies
b. Space Typologies
To achieve sustainable and resilient living, the property provides different types, dimensions and sizes of buildings. From studios to apartments, the proposal strategy can accommodate multi-generations and meet their needs. The buildings are also subdivided in different way to vary the density as well as have the potential to create spatial difference within itself (Sim, 2019).
From general to specific, different typologies of space that respond to different needs and activities can connect people to their surroundings and each other (Sim, 2019). To achieve diversity of outdoor spaces, the property provides a wide spectrum of needs for public and private life. Common houses - for the residents in each block, including meeting space, guest room, community kitchen, playroom and laundry facilities. Located in each corner where the residential blocks intersect to allow residents to share their culture and feel connected.

2' 1 2' 3
Considering the aspects of movement, intimacy, privacy and flexibility, the outdoor spaces are divided into sub-categories. The spaces are defined with thresholds, such as physical barriers, loose edges and different materials.
Based on the spatial interface strategy, the access points are treated differently. The proposed design also accommodates the flexible change of space depending on the needs and the time of the day. Car access - speed limit (20 mph) is set to improve pedestrian experiences (Department of Transport, 2010).
Public - the roads, cycling lanes and pedestrian pathways on the edge of the site Semi-public - the plaza and riverside outdoor space where whole community can enjoy together. It can act as a place for mobility (Sim, 2019).
Shared surface - a timed pedestrianised shared space between sidewalks. Pedestrians and cycles only between 8am and 6pm. Can be adapted as a car-free area if desired.
Semi-private - the courtyards mainly used by each community
Pedestrian route
Shared private - the shared gardens/shared terraces shared by 2-3 households
Improved existing cycle route - a cycling lane can improve walking experience by protecting the pedestrians from motorised traffic (Sim, 2019)
Private - the private gardens (deck, front/back gardens) used by one household

Inspired by the layout of the Urban Splash Town House, the shared private gardens are placed between the courtyard and the private gardens. Unlike the designed courtyard in the middle, they are managed by its residents. Two households share a single social garden.
Inspired by Marmalade Lane, gabion benches are placed as thresholds, creating opportunities to meet people and linger between different spaces.

Planters act as the thresholds. These are raised planters with trees between the shared space and the residential area, affording seating and a degree of safety and privacy.

Inspired by Kelham Island, the arch threshold is designed to separate the residential areas from the semipublic areas. It acts functionally and aesthetically along with the characteristics of Philadelphia.
3.4. ISOMETRIC 01 : THE BIG HOUSE (FRONT, STREET SIDE) 7. A timed pedestrianised shared space can be adapted as a car-free area in the future if desired. It is 100% pedestrianised between 8 am and 6 pm.
1. Cantilevered balconies give access to better views and capture the sun for a longer period of time (Blonder, 2017). The upper terraces on the first floor are adjacent to one another for those houses in which the inner terraces are separate.
LOCATION
THE BIG HOUSE Housing Type : 3 storey house, 1 unit Room Type : 3 Bedrooms with a kitchen, living room and lounge Size (m) : 5x10 Located near the communal building and plaza. Designed with a range of different types of personal space. A private backyard is perfect for people who wish to enjoy their own outdoor space. Designed for a family/shared house. Permanent rent is available.
FLOOR PLAN
2. The inner terraces on the ground floor are located adjacent to one another with permeable timber screening in between them which still allows for privacy. By designing inner terraces as an extension of the front garden, there is also the option for residents to adapt them for alternative uses, 1 such as a small shelter or bike storage. 3. A private front garden can be designed by the residents. A gentle and flat site ensures that it is wheelchair accessible.

5. A rain garden runs along the boundaries as a means of sofetening the edges, while gently directly people away people from the residential buildings.
6. Low railings (approx. 1m) promote interactions between neighbours while demarcating semi-public and private spaces. While still retaining the benefits of low height, it is a semi-permeable structure (e.g. railings on top of the wall) to provide privacy for groundfloor residents (Blonder, 2017).
3.5. ISOMETRIC 02 : THE BIG HOUSE (BACK, COURTYARD SIDE) 3. An inner courtyardfacing terrace could serve as a storage area for outdoor hobbies/activities, such as gardening or cleaning equipment. 4. The SuDS scheme acts as a natural boundary between two houses, and it is both ecological and aesthetic. Rainwater collected from the roofs is stored and can be used in the shared garden.

5. Private back gardens will help the ground-floor residents by acting as a buffer against any noise from activity in the courtyard. (Sim, 2019). 2

7. The edge zone is designed with a gabion bench which can both keep people at a distance from the property or be used to create a small social space. 8. The private shared garden is used by two households who live next door to each other. The sizes vary (min. 2m).
Figure 3-5&6. De Deeltuin, Utrecht
COURTYARD FUNCTIONS De Deeltuin created three atmospheres (a sunbathing area, a vegetable garden and a playground) in the courtyard which can meet the residents' different needs (Landezine, 2022).

5 1. Solar panels have been installed for efficient energy use, as the house is located in a sunny area.
6. The entrance to each home is designed with different materials to create two different zones: the social life in the courtyard and privacy in the inside and the garden.

2. A balcony designed to foster street-level interaction. To avoid such a long and narrow space simply becoming a storage area, it can comfortably seat two people (Blonder, 2017). A transparent glass railing allows people to see outside while they are sitting down. It can also be decorated with some climbing plants.
9. A bike and pet friendly environment. People can actively participate in the street and be connected to their surroundings.
10. The courtyard has three key roles. The picnic area is a mown grass lawn in the sun. The richly blooming garden provides an iconic view from their kitchens. The play area has a large specimen tree which the children will love climbing up. 31
3.6. ISOMETRIC 03 : THE RIVER HOUSE (FRONT, RIVERSIDE) 3. Loose thresholds between houses maximise interaction between neighbours.

4. Shared private gardens are for neighbours who live next door. Unlike the courtyard side, residents have a shared garden to encourage neighbourhood activities. 5. Arches are designed to keep people away from the residential area and to divide the spaces that have different functions: private property and residents' social area. 6. Waterfront location offers spectacular views and direct access to the water, creating a pleasant and comfortable outdoor experience with seating and a linear walkway.

THE RIVER HOUSE Housing Type : 2.5 storey house, 2 units Room Type : Studio 1, Studio 2 + Rooftop Attic Size (m) : 4x12, 3x4.5 (Rooftop attic) Located near the riverside and being open on both ends, it can have a view to the courtyard and the river. Designed with a terrace and upper green space, the rooftop attic is a perfect space for people who want extra room for hobbies or storage. Designed for young people or couples who want to have their own individual space. Temporary rent (min. 6 months) is available.
FLOOR PLAN Deck
1. Common balcony connects three different houses. Corridors are approximately 1-1.5m where residents can put pot plants or bikes in front of their house (Sim, 2019). As it is shared, it is accessible from the living room or the kitchen rather than bedroom to feel more welcoming (Blonder, 2017). Decorating one's own balcony area is available, such as a trellis, canopy and fairy lights.

2. Shuttered windows are flexible that can respond to the climate, offering easy and endless permutations inside (Sim, 2019). Windows are open from floor to ceiling, which can make the entire room into a virtual balcony without taking up space. 3. Access to the first floor is arranged by outside stairs with a small balcony (70cm deep). It can also be used as a small pot plant space.

CONCLUSION
"We Philadelphia", a bottom-up approach sustainable co-housing scheme, aims to support the inclusion of refugees in our society. In particular, the project will provide new 472 homes in addition to residential shops and other facilities. The strategy includes five housing types and a variety of outdoor spaces, ranging from private to communal. Along with the concept as a response to the current issues in the housing market, three key visions and strategies were formulated: connecting the community, providing a diversity of housing and open spaces, and supporting climate resilience. In addition, two community centric strategies, namely self-organisation and the local buddy system, will help to connect the residents.

"We Philadelphia" is a sustainable housing project that has been developed since October 2021. Throughout the design process, the housing scheme for the targeted group was well established and supported. In addition, explorations with the physical models and 3D scale visualisations were well processed. However, in terms of the density, each community block for the proposed site consists of around 80 homes, which might be overwhelming in terms of uniting the residents. Options for flexibility and adaptation were limited and could be developed further in the aspect of the built form (e.g., backs with a room for growth). Based on these improvements, the future housing scheme can be processed with better developed strategy and careful consideration.
