-Various Headlines about Singapore’s future
As part of URA Greater Southern Waterfront Plans, the planned relocation of the City Terminals to Tuas will free up 325 hectares of waterfront land. The areas now occupied by the City Terminals will present a redevelopment opportunity of enormous potential. Therefore, the year 2 cohort was given a high-rise residential master-plan over the former Keppel terminal and we had to think and present our ideas on what could be the future of housing to solve potential economic,social and environmental issues from our aging population and projected 6.9 million population. Another challenge was to preserve the spirit of the place. The Keppel Terminal has a long history of maritime trade and is a cornerstone of Singapore’s rapid development growth. Therefore, it is important that we take the history of the Keppel terminal in consideration and not completely build over it. I was inspired by the modular stacking cost saving nature of the shipping containers and decided that it would be the best inspiration for my project.

Breakdown of Solar Panels
1) The sun produces visible light which consists of photons. The solar panels are equipped with active solar trackers to follow the Sun path to maximize the solar energy captured. The panels consists of silicon crystals which absorbs photons and produces electrons as direct electrical current.
A) The Solar-panels are equipped with solar trackers which are light sensors that reads the amount of sunlight that is hitting the panel.
2) The direct electrical currents(Yellow) flows into batteries(Purple) to be stored. 3) When electricity is needed, the direct current from the batteries flows into the inverter(Blue) to be converted to alternating current(Red). The electrical cable runs down through the riser to the sky-terraces. 4)Lighting consists of Energy Saving LED to maximize the time the lighting run on the Solar Power.

How successful are Singapore’s public housing developments in catering to
Neighbourhood Identity?
Bras Basah Complex Selegie House
Content 1. Beginnings of Housing Development Board (HDB) 2. Bras Basah Complex 3. Selegie House 3. Bibliography
2
Beginnings of HDB After World War 2, 72% Singaporeans then were living in urban slums within the 80 square kilometers that was the central city area. The slums had no proper sanitation and lighting, creating unhealthy living conditions for the people, which is a factor to their endless cycle of poverty. The slums became a breeding ground for crime and diseases too.
Fig A. Scene showing the burning of a squatter called Bukit Ho Swee
The British Housing Committee referred to Singapore as “one of the world’s worst slums” and a “disgrace to a civilized community” 1
After Singapore gained self government, HDB was set up in 1960 to replace the former British colonial agency Singapore Improvement Trust (SIT). HDB immediately went in to work and soon faced its first big challenge. 16,000 people were homeless after the Bukit Ho Swee Fire and desperately Fig B. Emergency Flats
in need of urgent resettlement. HDB immediately
went to work, constructing row after row of similar slab blocks which simplified the construction process and laying of essential utilities. This ensured that HDB was able to construct quickly and be cost effective as well, leading to the resettlement of all families 3 months ahead of the promised 1 year deadline. 2

The nature of public housing is quite ironic in Singapore . One might think that it is monotonous in Singapore, just long imposing rectangular slab block or point blocks that are repeatedly built in a grid, creating a sterile alien environment to live in. As can be seen from Dutch Architect Rem Khoolaas’s Singapore SongLines,” the leap from the Chinese shophouse - typology that packs store, factory, family living quarters together in a single block around a courtyard to Singapore’s high rise containers is even more merciless, not only in terms of material difference - from the Asian to the western - but because the new inhabitants, cut off from connective networks of family relationships, traditions, habits, are abruptly forced into another civiliza-3 tion.”
Despite the repetitive nature of Singapore’s housing development, there are
still opportunities for resident to meet and bond, creating a neighborhood identity. Ultimately it will be the residents who create sense of belonging and community in the neighborhood. It is the people in the estates rather than the physical landscape that contributes most to the neighborhood identity. The definition of a neighborhood identity is that the residents have sense of belonging, culture and pride for their community. 3

Fig D. The Former shophouses standing at where Bras Basah Complex is now
Bras Basah Complex
1. Book and stationary history Bras basah Complex is podium style complex that was completed in 1980. The first 5 stories are taken up by shops and offices. Two identical residential blocks of 25-storeys then sit above the elevated void deck at level 6. To many Singaporeans, they would remember more about the large variety of book and
stationary shops there than the physical complex itself. The reason why it is a center of books and stationary is actually older than the complex itself. The complex is now standing on the former old streets of North Bridge Road, Victoria Street and Bras Basah Road which were traditional venues for book stores and stationery shops. After the shop-houses were demolished, Bras Basah Complex was designated to be a book center to rehouse the displaced business. The newly rehoused tenants then formed the Bras Basah Complex Merchant’s Association (BBCMA) in the eighties to work together, protect interest and settle common problems at the newly-built complex. These measures ensured that the community of book stores was not displaced and were able to continue their businesses at the same place.
5
This helped to retain the book and stationary culture of the place and customers were ensured that their favorite stores were still around. Therefore, the stores were able to maintain their customer base uninterrupted and the identity of books and stationary continue to grow. When creating a neighborhood identity, HDB had to respect and take in consideration the people’s way of living and ensure that they will able to carry on their business smoothly in their new homes.
2. Language and cultural showcase of the complex Entering the complex from the bustling road into one of the atriums ,one would notice that it is a quiet place due to the nature of the business here. The 5 levels of corridors that connect the shops are cantilevered, creating a free and open facade that allows people to
Fig E. Retail Levels
have quick glance at all the shops surrounding him or her, creating a unique vibrant visual identity for the complex. The open corridors also allow unimpeded visual connectivity between shops on different levels, allowing shop owners to watch out for each other and be visually connected, contributing to the sense of community of books and stationery. Many of the shop owners would expand out onto the corridor, lining their racks of goods along the corridor, similar to the 5 foot walkways of the previous shophouses. This creates a sort of cultural walkway and art walkway that showcase Singapore’s different languages and literature genres . The various atriums also serves as light and ventilation portals, ensuring that the corridors are bright and airy for browsing books and stationary, nurturing the bookshop culture. The atriums also serve as places of relief and meeting points, allowing cultural events like Chinese calligraphy and singing to be held.
6
This attracts people from the outside, connecting the complex to the urban fabric. Similar to the mixed used nature of the shophouses, the retail levels are also directly connected to 2 housing blocks above. Therefore, residents have quick access to shops below and likely bump into their neighbors, helping to strengthen relationships between neighbors.
3. Resident bonding Unlike typical HDB blocks where the void deck is located on the ground level, the void deck in Bras Basah complex is located above the retail level. As the Complex is in the bustling city area, the elevated void deck creates a quiet and more private environment for residents to socialize. The elevated void deck also creates a safe environment to for children to play as they would not run onto the bustling road if the void deck was on the ground level. The void deck is equipped with Fig F. Elevated Void Deck
playgrounds, fitness corners and gardens,
attracting people of different generations from their homes above, helping to create bonds between neighbors. The raised void deck also becomes a viewing platform to view the skyscrapers around, creating one of a kind scenic void deck in Bras Basah. The Void deck becomes a key point of the complex, creating a distinctive identity for the Bras Basah Complex. Due to the lack of public spaces in the vicinity, the void deck acts as a public square for mass dances in the cool of the evening, ensuring that the complex is still lively as a place of culture at night.

Fig G. Corridors linking the units to the lift lobbies
4. Elevated streets From far, the complex might look very dull and uninspiring but upon closer look, one can see the cultural and religious context of Singapore. Walking along the corridors of a housing block, you can see pots of plants growing along the edge of the concrete balustrade. As a result of Singapore bright and hot tropical climate, the corridors are designed to be as bright and airy as possible, allowing a suitable environment to plant. As each family have their own preferences of plants, it adds unique greenery to the 2 housing blocks despite being constructed similarly. From the type plants grown, one can deduce the ethic type of the family, the Chinese tend to plant bonsai plant while the Malay and Indian families might plant spices like chili and turmeric. Therefore, each block becomes a canvas to the city, presenting the residents socio cultural backgrounds, contributing to the complex identity. Also as the corridors are wide and open to the public instead of being close and dark, the residents feel safe walking along without needing security. Therefore, residents will be more open to neighbors and not suspicious towards their each other and will more likely socialize with their neighbors, creating the sense of community.

Selegie House
Fig H. Image showing the crowd at Selegie House on 31 May 1963, the day of official opening by former Prime Minister Lee Kuan Yew.
5. HDB early successful prototype Although the name implies a single dwelling unit, it actually consists of 2 ten storey slab blocks and one 20 storey slab block with
shops on the ground level. Selegie House was built to relieve over crowding in the city area and was one of the earliest projects to introduce modern high rise living to people who were still in cramp unsanitary shop houses and slums. It was an important project not just because of the need to rehouse the booming post war population but also in public relations to prove and encourage people that highrise blocks that were being built were more favorable to move in. Selegie House is precursor to many HDB city complexes including Bras Basah Complex and introduced pioneering features like proper sanitation, being mixed use with shops below and homes above and long open bright corridors for residents to plant and mingle. However, the distinctive blocky red and white facades that you see was not present in the original design and the estate itself have undergone major changes during the years due to rapid changing standards of living.
9
Fig I. Image showing open bright corridors with the added covered pavilions and walkways at the ground level
6. Better homes for future communities to live When it was constructed, it was advanced at that time for fast lifts and proper sanitation. However, units have become too cramped for present standards and like many other older flats were suffering from maintenance issues like spalling concrete and the lack of barrier free facilities compared to newer flats. As a result, younger families and couples moved into newer flats instead and this lead to an aging population in older estates like Selegie House. This created an unhealthy ratio of the elderly to the young in older estates and this would worsen the generation gaps within communities. Therefore HDB started the Main Upgrading Program (MUP) and in Selegie House, a 6 metre square room extension was added to the kitchen and drying racks were added to make it easier and safer to hang clothes. Lifts were upgraded to stop at every level with clear glass panels in doors to reduce the claustrophobic nature of the lifts. The entire estate was given a fresh coat of distinctive patriotic red and white paint and is now famously known to feature hundreds of National Flags during NDP. Therefore to maintain healthy neighborhood communities for years to come, HDB had to pay attention to the changing needs of the people and upgrade older HDB estates as required.
10
Younger couples and families would be more willing to live in older HDB estates and help create strong supportive communities of young and old. This measures give a new lease of life to old estates, allowing the estate to thrive and develop its neighborhood identity for years to come. This helps to ensure that old community estates like Selegie House will not be run down and be forgotten in Singapore’s rapid urban pace of life. Despite being 53 years old, it continue to stand tall as living testament of Singapore’s rapid post war independence development for the younger generations to learn and is an integral part of Singapore’s history.
7. Maintaining Communal facilities
Fig J. Images showing added exercise corner, playground and Guan Seng Provision Shop
Originally, the estate just had shops and bare open spaces at the ground level for recreational purposes. However, keeping in line with the aging population, there are now exercise corners and covered pavilions to ensure that the elderly still can keep fit and have opportunities to meet with their neighbors, strengthening community relationships till their twilight years. The exercise corners and pavilions are conveniently located beside the playground so that the children and elderly would bond with each other, maintaining cross generational bonds. Many of the shops seem to be stuck in time and still have the distinctive old school aesthetic and are opened for quite a few years. As the shops are still present for many years, this creates deep sense familiarity in the estate, helping to create a tightly knit community between the business and residents. With the added barrier free ramps, handrails and lifts, the elderly residents would find it more comfortable to walk around outside of their units and mingle with other neighbors at the shops at the ground level.
11
Summary As seen from the Bras Basah Complex and Selegie House, HDB had a holistic approach to creating long term communities from minimizing difficulties from relocation from shop houses, designing familiar and inspired spaces from shophouses to long term maintenance for homes and public areas.
Going back to Rem Khoolaas’s Singapore Songlines, his perspective was that during Singapore’s rapid development from shop-houses and slums to the modernist high-rise, much of our culture and lifestyles was simply wiped out and entirely remade. It is true that the way of living in Singapore have radically changed, however much of the people’s cultural and religious identity have actually survived and instead been relocated and are openly expressed in our HDB estates today.

ZERO ENERGY BUILDING Singapore, DP Architects
It is the first Zero Energy Building in South-east Asia because the building produces enough energy to run itself. ZEB houses offices, classrooms and a resource center. The building aims to achieve this through a combination of green building technology, clever building design that takes advantages of natural ventilation and lighting (this is called ‘passive design’), and the harnessing of solar energy.

BAHRAIN WTC Bahrain, Atkins Architects
A 240-metre-high (787 ft), 50-floor, twin tower complex located in Manama, Bahrain. It is the first skyscraper in the world to integrate wind turbines. Bahrain world trade centre harnesses two sail shaped office towers, to direct the prevailing winds to the wind turbines (windmills) which are installed on the building’s facade. The two towers are adjoined by a Hotel and shopping mall.
Windy as Bahrain is a coastal city off the Persian gulf with maximum performance of 225KW each during 15m/s to 20m/s wind. Built up area only reach a maximum of 60m which does not block the wind Solar panels not used due to hot desert temperature (50 degrees Celsius) which decreases the efficiency of solar panels.

Horizontal Axis Wind Turbines (HAWT)
-Similar to a windmill, with blades that resembles a propeller that rotates on the horizontal axis. -have the main rotor shaft and electrical generator at the top of a tower, and MUST be pointed into the wind (unlike the VAWT). Since the blades are running perpendicularly to the wind, it receives power through the whole rotation. With that, it is of a higher efficiency.
Vertical Axis Wind Turbines(VAWT)
-Main rotor shaft arranged vertically hence the wind turbines does not need to be pointed into the prevailing wind. -Advantageous for sites where the wind direction is highly variable or has turbulent winds with inconsistent wind patterns.
Micro Wind Turbine System
-Consists of VAWT which seamlessly retrofitted on the building to harness energy from exhaust air which have been produced by air-conditioning and mechanical ventilation systems The enclosure of the VAWT is designed with several guide-vanes placed at the up-stream of the wind turbine to guide the wind before it reaches the turbine blades. It also consists of diffuser-places that helps to draw more wind and increased the acceleration of the wind flow.

BAHRAIN WTC
Wind energy is not suitable as consistent wind is needed for conventional wind turbines. Bahrain WTC experience winds up to 46kmph for 16 percent of the year and has two large towers to divert wind towards the 3 turbines. Also, not surrounded by buildings greater than 60m, allows smooth uninterrupted wind. However in Singapore, wind speed only reaches up to 34 kph for 16 percent of the year and the project site is in a sheltered port surrounded by Pulau Brani and CBD areas that blocks wind. In addition, wind directions in Singapore changes throughout the year because of the seasonal monsoon. This could damage the wind turbines and even structures of the building.
