1.0 SITE INTRODUCTION

Jalan Raja Abdullah Jalan Raja Abdullah is one of many roads located in the neighbourhood of Kampung Baru in central Kuala Lumpur, and was originally known as Hale Road, named after the Collector of Land Revenue of Kuala Lumpur and Registrar of Titles for Selangor, Abraham Hale (Figure 1.0), due to his contribution in the creation of Kampung Baru. In the 1970s, however, Hale Road became present day Jalan Raja Abdullah, aptly named after Raja Abdullah, who in the 19th century alongside his brother Raja Jumaat were instrumental in the opening of tin mines in Klang Valley, especially in Ampang. He was also responsible for bringing in 87 Chinese tin miners from Lukut, eventually laying the foundation for the establishment of Kuala Lumpur.

Founded in 1899, Kampung Baru / “Kampong Baharu” is a name given by the British government at the time (Federal Malay States) to call a cluster of smaller villages that each already had their unique names. It is classiﬁed as the oldest residential area in Kuala Lumpur. They intended for the people to be “Malay”, so as to “educate the children of Malays” to take part in the administration and enable them to reap of the present prosperity but the settlers were subjected to settlement tax and contract rules (e.g.) ﬁnes for failing to cultivate plots. Despite the modernisation of times’ past, this village in the city has a stronghold on its historical remnants, as it can be seen through the many traditional Malay wooden houses, and also due in fact that its inhabitants refused all forms of transformation.

1.0 SITE INTRODUCTION

1900

1927

1950-1965

Kampung Baru started off as a village; a cluster of houses in a neighbourhood context. Agriculture was prominent within the village; chilli, banana, paddy, herbs, and etc. Jalan Raja Abdullah, formerly known as Hale Road, is situated at Kampung Hujung Pasir.

Infrastructure such as tarred roads, street lighting and roadside piped water were implemented. Jalan Raja Abdullah/Hale Road was the ﬁrst of the roads to receive such upgrades. Road networks appeared to be constructed according to a plan.

High-rise buildings have begun to develop on areas to the left of Kampung Baru. The settlers of Kampung Baru were given land titles, which meant that the area was to be developed and owned exclusively by the Malay ethnic group – resulting in the diﬃculty of “outsiders” obtaining the many plots of land for future developments.

1970

1990

2000

The massive ﬂood of 1971 resulted in the Klang River being drastically straightened, deepened and widened, to mitigate ﬂood occurrences. The image of Kampung Baru worsened as this resulted in a physical separation from Jalan Ampang.

The Light Rail Transit (LRT) stations were opened to provide access and connectivity to the rest of Kuala Lumpur for both visitors and residents. Constructed underground, indicative of the 1965 settlement.

High-rise buildings have spread to nearly all areas of Kampung Baru; as if swallowing it. From a network of well-connected roads to a cluster of highways and multiple smaller roads. Situated in a congested city, Kampung Baru/Jalan Raja Abdullah is a village in a city, with redevelopment plans still up in the air.

1.1 URBAN MORPHOLOGY TIMELINE

Zoning

Key Plan (nts) The proposed site is located in between Chow Kit and Menara Kuala Lumpur. It is right below Kampung Baru and above KL City Center, right at the edge of the suburb along the Klang river.

District The Proposed site sits at the edge Kampung Baru (Residential) alongside Klang River with corporates and institutions across the river; whereas the site can be easily accessible to the commercial shops and buildings. The proposed site is accessible via Jalan Raja Abdullah and Jalan Dang Wangi. It sits above the river bank of Klang River with Dang Wangi LRT station connected on the other site. The site is also surrounded by multiple main roads and highways.

2.0 COMPONENT 1

DESIGN STATEMENT Upon our site analysis of Jalan Raja Abdullah, Kampung Baru, there were several problems identified on-site and we are to propose a high-rise dwelling that resolves some of these issues. The proposed design idea is to cater towards the existing demographic on site which mostly consists of the youth (18-29) and working class adults (30-59). Providing a sustainable community through the act of co-living which is essential towards upholding the future of Kampung Baru. In order the reach this objective, the design proposes to accommodate multigenerational living. Qualitative findings suggested that increased psychological flexibility and self-compassion encouraged co-living residents to be more vulnerable and trusting, which enabled communication regarding one’s needs and enhanced mutual social support and relationship quality. This, in turn, improved overall boundary management, work-life balance and well-being. Originality and value of Co-living settings – while contributing to overall sustainable development through more efficient use of space and resources – can also contribute to societal and individual sustainability. However, to ensure this contribution, the physical environment including private areas and common and semi-public areas need to be considered (Mellner, 2021). The most common disadvantage of a highrise apartment is its ability to properly address community interaction as well as lack of green spaces for residents. Buildings that do provide these spaces are often met with the problem of contested ownership as there are desires for more space and personal needs (Hadi, Health & Oldfield, 2018). Thus, to resolve this issue, each unit is provided with its own private garden space and community spaces (eg: breakout space, cafe, amphitheatre, laundry?) throughout the building, which reflects to how the local community live. The idea of this design hopes to improve the current situation of Jln Raja Abdullah by bringing in the youth and working adults to create a positive change in environment, to ensure a sustainable social community and economy.

Shadow casting and sun direction at 5pm

From the sun path diagrams, the proposed site receive the most exposure on the east and west orientation. Certain design strategies are needed to be introduced to the building in order to properly handle the immense sunlight and heat transfer during day time. The proposed solution to introduce is recessed facades of certain units and green balconies. Vine planting was proposed as an additional form of building envelope to provide protection against the sun.

5.1 FACADE STRATEGY

SCALE 1:350

A grid of 9m x 9m is utilised for maximum car park and unit design eﬃciency as the unit types are design to ﬁt in the 3m division.

Final Mass

The building incorporates prefabricated reinforced concrete columns and beams, along with reinforced concrete walls and slab. The building is fully supported by the reinforced concrete columns and beams as there is no transfer slab. Cantilever beams to support the protruded slabs.

5.2 STRUCTURAL CONSIDERATION

Two main cores (indicated in red) are located at strategic locations of the building to cater to the residents. It also acts as a support to the whole building mass. Separate ﬁre escapes (indicated in purple) are located at various locations n levels in compliance with the by-law.

SCALE 1:350

The occupancy load is shown in the table below. The exit width is to correspond to the occupancy load per ﬂoor and shall comply with the requirement according to the 7th schedule in the By-Laws. Based on the calculations, the minimum exit width is 0.55m and the total staircase width provided is 9.3m, thus being in compliance to the aforementioned by-law.

Occupancy Load (3rd ﬂoor)

According to the 7th schedule, occupants load for Purpose group III. Other Residential/Flat = 24/m² Occupancy Load per ﬂoor = total net area/24 = 612m²/24m² per pax = 25.5 = 26 pax

2. Units of horizontal exit width According to the 7th schedule, capacity exit for Purpose group III. Other Residential/Flat = 60 per unit Unit of exit width required = 26/60 = 0.76 = 1 unit

5.3 FIRE PROTECTION STRATEGY & OCCUPANCY LOAD

In this building, automatic sprinkler system is introduced. According to 7th Schedule for Purpose Group III, it falls under “other residential” section which 10m dead end limit and 45m travel distance is required. All unit layout conﬁguration comply within the maximum travel distance. Due to the design of staircase and lobby area are providing with permanent natural ventilation as open design, protected lobbies may be omitted which abides to UBBL By-law 197(protected lobbies). Emergency light is provided along the corridor and staircase; hose reel and dry powder.

3. Minimum required exit width = 1 x 550 = 550mm = 0.55m 4. Exit width provided = staircase 1 + 2 + 3 + 4 = 3.0m + 2.1m + 2.1m + 2.1m = 9.3m (>0.55m)
