1.5 Site Condition The triangular shaped site is dominated by the derelict 12 storey Brunnel House building that fronts The Hard (Figure 15). The site also comprises one public house and taxi office on the corner with College Street, which is currently still running in business, and one former commercial garage at the corner of Victory Road an ageing decked car park (2 storeys) at the rear of Brunel House. 1.6 Site SWOT Strength • Strategic Location - Next to Transportation Hub. • Highly Accessible - located along the main road. • Close Proximity to Public Facilities, Commercial, The Hard Transportation Hub. Weakness The existing derelict building is an eyesore and may give negative impression towards the people especially to the newcomers as the site is located next to the city gateway.

figure 16 : PCC SPD For The Hard
• Vision of The Hard Masterplan The Vision set by Portsmouth City Council in the Supplementary Planning Document (SPD) June 2012 are to shape The Hard into a vibrant waterfront destination, building on its function as a key city gateway and its reputation as an area of historic character and charm. New passenger facilities, cultural opportunities and places to live, to work, to stay, to eat and to relax will enhance the experience of visitors and residents alike. The creation of a distinctive public realm will revitalise and transform the area. • The Hard South // The Proposed Site Currently, the strategic location of the site is not being fully utilized. The abandoned Brunel House not only an eyesore to the local people, it could potentially gave a bad impressions towards new visitors as the site is situated at the main gateway into Portsmouth City. This unused urban space should be used to accomodate building that has beneficial values towards the local government, the client and the local community. • Linking In With The Hard Masterplan In order to gain development consents from Portsmouth City Council, it is important to follow the criterias sets by PCC in the SPD for future development of The Hard South. The criterias are as followed :1. Significant opportunity for a mixed use development. 2. Incorporating a landmark building addresses both The Hard frontage and interchange area to the west. 3. Active ground floor uses will be extremely important in this location fronting The Hard. 4. Appropriate uses could include small scale retail (maximum 280 square metres per unit) serving the local community and tourism markets, cafés or restaurants. 5. The upper storeys could accommodate a hotel, conference centre, leisure uses or office suites. 6. An element of residential accommodation would also be acceptable on the upper floors.

3.1 Client’s Ambition
The Hard Food Centre & Youth Home // Portsea,Portsmouth
3.2 Youth Homelessness
• About The Client & Their Mission Portsmouth City Council (PCC) will be the main funder and in collaboration with a non profit organisation, The Foyer Federation (TFF) with the main mission to achieve the vision for all young people to have a chance to realise their potential, build a thriving, independent and sustainable adulthood, and become a valuable asset to society. • About The Foyer Federation (TFF) The Foyer Federation was established with a sole purpose to help transforming the circumstances of young people who have faced barriers in their lives. The non profit organisation has a network of 120 accredited learning and accomodation worldwide known as ‘Foyers’. These Foyers provide up to 10,000 16-25 year olds per year with mutually agreed, tailor-made programmes which give the young people access to housing, learning, personal development, training and employment opportunities in line with their needs and goals. • Intergration across Government body, Non Profit Organisations and Communities In order to have an effective,reliable and sustainable building operation in a long run, a strong cooperation must be forged between Portsmouth City Council, The Client, other non profit organisations networking together with the help of local communities. This is to ensure the proposed building scheme can achieve the project mission. • The Foyer Federation Networking The non profit organisation that will heavily involved in running the programme after the proposed building has completed includes Portsmouth Food Bank and other networking partnership includes John Pounds Centre, Centre Point, Two Saints, Shelter, Crisis and other voluntary bodies.

• Homelessness in UK More than 300,000 people are now categorised as homeless in Britain after a spike in numbers in the last year. According to a study by a non profit body, Shelter, found that 307,000, or one in every 200, people are now either sleeping rough or in temporary accommodation. Although the figure has risen by 13,000 in the last year alone, Shelter said the partial nature of government data means the real number of homeless people is likely to be even higher.The number of homeless people nationally - including rough sleepers and those in temporary accommodation - will rise to 575,000 by 2041. London has the highest number of rough sleeper/ homeless with South East Region came second based on the study. (300,000 people in Britain are now homeless (2017, November 8), Independent. Retrieved from http://www.independent. co.uk)
• Effect to the Youth Public view homelessness as the result of personal failings or incompetent behavior, and if the economy is going well, there is no excuse for not getting on. Theoretical, historical and international perspectives indicate that the causation of homelessness is complex, with no single “trigger” that is sufficient for it to happen. Study has classified the causes of homelessness into two categories, Personal circumstances and Structural factors. These problem categories play a role – and interact with each other – and the balance of causes differs over time, across countries, and between demographic groups. 402.3 // Portfolio// 402 Architectural Design - Synthesis // The Hard Food Centre & Youth Home// Portsea,Portsmouth

3.3 Portsmouth Food Market & Cookery School • About the Proposal The proposal for the development of the site would be a mixed type use that includes Cookery Workshops, Student Accomodations, Food market, Food Bank, Food Growing Area and other related facilities. Key elements of the development :1. Cookery School Cookery school is a programme where students will be learning about cooking skills. The programme will be held in the cookery workshops. These workshops can be utilize for public programme where community based cooking classes can be held on the weekend.
• Project Aim The main aim of the project is to reduce number of youth homelessness and unemployment throughout UK, in a long run through the educational opportunities in cookery courses. This opportunity would hopefully help the youth community to achieve a better, positive and independent life after the completion of the course. The development would also improve the image of the site while creating a building that would make the site better in term of the existing cityscape, pedestrian connection, security, and activity.
2. Food Bank The Food Bank is to sustain the Cookery School programme by collecting donated food from various non profit organisations and local supermarkets before the supply will be use for the Cookery School. 3. Food Market Food Market consists of booths that promote and sells various type of cuisine. The booths will be run by the Cookery School students and also local businesses.
4. Student Accomodation The Student Living area consists of hostels and other common areas where the students will be staying throughout the course. The minimum length of stay would be 4-6 months and the maximum length would be 2 years. 5. Food Growing Area Food Growing Area serve as a space for the students to learn on growing their own vegetable as well as supplying the cookery programme.
• Target User (Cookery School Program) Young adult and adult ranging from 16 to 27 years old. • Length Of Stay Minimum stay: 4-6 months Maximum stay: 2 years

4.2 Design/Structural Exploration The followings are Key Design Stages and Progress prior to the Final Outcome. Week 2-3 The key design concepts during this stage:- The idea of minimize building footprint on the plinth level. - Structural cores are placed in a grid system where all the spaces and rooms are revolve around these cores. - The creation of structural cores allows the ground floor be “free” and allows pedestrian to walk through the building. - The levelling difference of the Spaces create unique visual connection. - The rectangular structures are too big and will create a lot of blank walls on the ground floor.
Week 4-5 The key design concepts during this stage:- Allign with the same core idea from previous week. - Explore wooden Lattice Structure frame as a substitution of the previous heavy structural cores. - Precedent 1 : Kengo Kuma’s Sake No Hana, UK. - Precedent 2 : Kengo Kuma’s Yusuhara Townhall, Japan. figure 26 : Sake No Hana, UK

Week 7 The key design concepts during this stage:- Exploration of new structure based on the interim review feedback. - Precedent 3 - Toyo Ito’s Sendai Mediatechque - The “Tube” is a lattice structural columns where the technology can be well integrated with R.C. Structure. - The “Tube” not only allows less structural footprint while supporting the top floor, but it would allow natural lighting to penetrate into the ground floor.
Week 8-9 ( Interim 2) The key design concepts during this stage:- The number for the “Tube” is reduced and the focus is to use the Tubes as a way to only support the upper roof garden. - Conventional R.C. Structure will be used for the Main Building to suit its simple rectangular form.

MASSING STRATEGIES
1.Optimal Orientation In order to gain effective solar gain and achieve natural ventilation, the building is orientated according to site analysis.
2.Maximise Usage of the Building Plinth The first idea is to maximise the built area for the ground floor as it is the most crucial level of the proposed building.
4.“Capturing” the Axes of Pedestrian Nodes Recognising and arranging the building plinths according to the Pedestrian Nodes/ Main Pedestrian access Points. (Mainly from Gunwharf & The Hard)
5.“Encourage Pedestrian Flow” The creation of passageways in between the building blocks would allow passersby to walk through the building thus ensuring continuity of pedestrian flow.
402.3 // Portfolio// 402 Architectural Design - Synthesis // The Hard Food Centre & Youth Home// Portsea,Portsmouth
3.“Opening More” Building Plinth is key in avoiding the building becomes alienated and secluded from surrounding, thus it needs to be open more.
6.“Food Market as Main Attraction” The Food Market is allocated in front of the busy frontage as a way to invite the public into the building.

5.0 // PROPOSED DEVELOPMENT
The Hard Food Centre & Youth Home // Portsea,Portsmouth
7.Transparent Facade Transparent Facade for the building plinths where it would encourage visual connectivity between people inside the building - pedestrian on the surrounding street.
8.“Reduce Structural Intensity” The combination of Triangular steel structure with glass facades would reduce structural intensity and building mass. The Roof Garden Structure will also have skylight to allow sunlight penetration into the Food Market below
9.Public - Private Hierarchy All the bublic spaces are allocated on the ground floor, whilst Semi Public and Public Spaces are allocated on 1st Floor up to the Top Floor.
10.Optimal Accomodation Orientation The Student Accomodation is orientated according to sun path as part of the passive solar heating. There are two wings of Student Accomodation; North-South Facing and East -West Facing.
11.Vegetable Roof Garden as Focal Point Vegetable Roof Garden is located above the Food Market as the main connector for all the Student accomodation, where this plane will be utilized for gardening, meeting and socialising among the student community.
12.“Housings have view towards the Garden” All the housing units will have view towards the Garden, connecting the community visually.

6.0 SUSTAINABILITY 6.1 HVAC SYSTEM Heating, Ventilating and Air Conditioning (HVAC) Comfort HVAC system is key for the proposed building to achieve thermal comfort and good indoor air quality. HVAC allows the process of replacing air in internal spaces which involved “temperature control, oxygen replenishment, and removal harmful elements which could lead to “Sick Building Syndrome”. As shown in the diagramme below, there are various ventilation strategies according to different part of the building. Spaces that requires mechanical ventilation would include Cookery Workshops and Kitchen. Mixed-mode ventilation (allow both Natural and Mechanical) is used for spaces like Food Market, Offices, Cafe and Common Room.

6.3 NATURAL VENTILATION
The proposed building, especially Student Accomodations were designed to utilize the potential of using natural wind to ventilate the indoor spaces. Natural ventilation is important to ensure good air quality and comfort condition can be achieved inside the building spaces. Each Student Accomodation is designed to have openings at both end where it enables Cross Ventilation that optimize the path air follows through the building. Additionally, based on discussion with Environmental engineer, more openings will be provided for the Food Market, where Stacked Ventilation can happened to ventilate the interior space.

6.4 MECHANICAL VENTILATION
Mechanical Ventilation Certain spaces like Cookery Workshop requires Mechanical Ventilation where it uses mechanical fan to ventilate air in and drive stale air out. Due to the nature of cookery programe (which produce smoke, airborne grease, combustion products, fumes, smoke, odors, heat, and steam), extractor hoods would be installed where it will channel the unwanted air out and maintained comfort inside the spaces. Mixed-Mode Ventilation Spaces like Food Market, Offices, Cafe and Common Room will adopt the mixed mode ventilation which uses both Natural and Mechanical technique of space conditioning. The Mixed mode ventilation allows flexibility where these spaces can use natural ventilation through operatable window or air-conditioning, depending on different seasons or occassions.
