1.0 OUTLINE 1.1 Abstract COMMUNITY PARLIAMENT The design prposal challenges are to create a architectural position, progressing from the urban issues of urban street environment , development of architectural position, proposing strategy to resolving social issues pertinent within the conditions of the urban landscape (neglected communities, school, youth centre). the site and program was developed, addresses the social needs of a particular urban place and provide interaction and connection of people in the urban spaces.

The project aim is to exploring the topic of sustaining humanity. The ‘urban design’ side is about the building (or a family of smaller buildings) that sits well and quietly in the neighbourhood, architecture that fits in to the street, is made up of recycled or sustainable materials, lets in lots of light, some rain and is open. We are interested in movable stuff; pulleys, shades, screens, ‘floating’ design, shadow details, shade and rawness. Hence, a Social Centre for Giving Back.

The ideas of ‘Community’ and ‘Urban Design’, a socially-driven nexus where locals and visitors can be seen together; where a soup-kitchen exists for homeless people to get free food and eat it in a nice manner and context; where a permanent flea-market sells homemade products or recycled/upcycled goods, fresh produce and food; a place where visitors can pause for a while, have a shower, get refreshed and chill out; a place with an indoor/outdoor amphitheatre where films are shown or talks held; a place that houses a community workshop where independent things can be made (and later sold); a place that is safe as a refuge where some temporary accommodation can help a small family or individual get back on their feet; a place with some shops, pocket parks, big trees, some day beds and lots of chairs and tables. Building on design brief and pre-analysis of context, user and programme, spatial planning are required to design a building that delivers a strong relationship to place, people and time.

2.0 CONTEXTUAL STUDY 2.1 Site Introduction Jalan Alor is well known in KL for all sorts of reasons, has a ‘history’, is a peoples place, draws in the crowds and tourists, is strategically located, has a mix of really old, old and new buildings, has a great ‘urban design presence’, is well shaded by existing trees and the local people. We believe its an ideal location for a Social Centre.

Film theatre and film workshops was the catalyst design a film theatre that utilizes the textures, and patterns as landscape design while the park is approximately 250 metres long and extends from film theatre running parallel to Alor Street which directs and captures the diverse forces and flows within the site to create flexible conditions for future events and program. The design project seeks to transform a existing car park to a platform which can be used for a variety of public entertainment, recreation, and city celebration. using the alignment to with tourist and recreation facilities, creating activity nodes and spaces on both sides, generate visual interest. This will bring together community members and to learn, discuss and get involved in today’s critical social issues. presents the opportunity for living, working, and recreation to make a positive changes and give back to our society.

2.0 CONTEXTUAL STUDY 2.2 Site History

Jalan Alor located behind Jalan Bukit Bintang, formerly known as red light district of KL. The street was predominantly Chinese area but has transformed into a melting pot of cultures in the past years. Pre-war, colonial shophouses have been refurbished into trendy bars and restaurants.

Relatively quiet during the day, the entire street is transformed into a lively outdoor food court, selling a variety of mainly Chinese cuisine at night. As it has steadily evolved into a well-known food district and tourist landmark, Bukit Bintang LRT station started its construction in 2002 and Bukit Bintang Sentral MRT station in 2012 to serve as transit interchange for commuters.

2.0 CONTEXTUAL STUDY 2.3 Site Issues Issue 1: Connectivity The Typology varies across the area, but a clear denomination can be appreciated.

Generally, closer to our site and along the main street of Jalan Alor, the main type of buildings are shophouses with eateries on the ground floor and residential building housing on the floors above, which makes them a mixed-used development.

Moving further outwards from the site in a radial manner, the outskirts of covered area begin to converge to rather more commercial districts, Issue 2: Lack of Identity Common building typology across the surrounding which includes Jalan Pudu, Jalan Tong Shin and Changkat Bukit Bintang.

Issue 3: Privatization of Space

Issue 4: Lack of Public Open Space

TIFF Bell Lightbox Architects: KPMB Architects Location: Toronto, ON, Canada Architect: Kuwabara Payne McKenna Blumberg (KPMB) Architects The building features cineplex, two restaurants, major exhibitions, and learning and entertainment facilities. TIFF has remained committed to educating and broadening audiences, adding to the cultural richness of Canada’s community.

It was also designed to reflect the heterogeneity and openness that characterizes Toronto.

The King Street elevation is a composition of projecting volumes and surfaces contained within a continuous loop of movement that begins with the street level canopy and then rises to the upper levels to culminate at the stepped roof. The canopy, with its metal soffits and LED lights, enhances the arrival experience.

Extended sequences of horizontal montages of clear, fritted and translucent glass panels animate the upper surfaces and in project the silhouettes of people moving within to the street.

Inside the Lightbox, the design acts as a framework for human action and imagination in which the solidity of architecture and the ephemerality of the medium of film are fused.

The flexible plan is based on the tradition of industrial loft buildings. Within this framework, the volumes of the cinema theaters (ranging from 80 to 550 seats) and spaces for gathering, display and production are arranged to promote movement and visual connectivity.

A three-story central atrium features a red framed glass window into the master control booth. The architectural volumes of the five cinemas are expressed as black zinc clad buildings within the building, and the spaces between act as interior streets along which visitors are oriented. The cinema interiors are dark, unadorned and enclosed to focus the attention between viewers and film.

3.0 DESIGN AND SOCIAL IMPACT 3.3 Design Intention Live- Accommodation block to cater artists, individual or families in need of support.

Work- Job opportunities offered in film theatre, cafes, and restaurants for people in need of financial support.
