INTERDISCIPLINARY TEAMQhawarizmi Norhisham is currently pursuing his Masters in Archi-tecture at UiTM Shah Alam. Since 2010, he is vigorously active in participating in both national and international architectural competitions. He founded a group which promotes an alternative wave of design and research in experimental ideas.

Muhammad Shamin Sahrum has been a wan-dering nomad for the most part of his architectural years, including workshops in AEDES Berlin (Germany) as well as University Technology Sydney (UTS, AUS) . He is a strong believer that architec-tural practice must be tied back to edu-cation and that collaborations between various creative fields enriches the architectural process and experience.

Yasmin Rahman is in her fourth semester of the Master in Archi-tecture (UiTM) program. She con-sistently questions the notion of experimental ideas in archi-tecture and processes of archi-tecture through a jint website, MDRXA.

Haikal Mansor dwells in the field of Zoology and Marine Biology, aside from his architectural background, for the most part of his life he has been very much into animal and wildlife conser-vation.

Norhafiza Roslan is currently undertaking her Masters in Pe-troleum Chemistry in UiTM Shah Alam with extensive background in Applied Sciences. Her work as a researcher is vital in providing real world data for the team.

PROPOSED SITE

Jalan Pantai Dalam,59200 Kuala Lumpur, Federal Territory of Kuala Lumpur

Pantai Dalam is a perfect watershed between two groups of urban Malays: the affluent and the working class. The former live mainly in gleaming, whitewashed con-dominiums like the Andalusia Condominium in Pantai Hillpark, or in luxury bungalows in Kampung Pantai and Pantai Halt.

For the working class, the luxury apartments located further uphill are perhaps symbols of what one can aspire to. Most of them live in the low-cost apart-ments.

DESIGN RATIONALE: IDEA

“Berniagalah kamu kerana sembilan persepuluh punca

rezeki adalah di dalam perniagaan.”

Hadith ini diriwayatkan oleh Nuaim bin Abdul Rahman

Ihya’ ulumuddin

Whenever we think of urban housing, the images of dilapidated dwell-ings pops up. A place associated more with improvishment and economic in-equality than with happiness and laughter. What if it were possible to create a new typology of social housing that could give its residents the leverage of creating economic opportunities ? Say a flexible dwelling within the confines and budget of social housing, but with the added function of enlarging a space as needed.

This much needed space would become the catalyst for residents to be-come their own entrepreneur and set up their own SME (Small Medium En-terprise) bussinesses. This economic empowerment would give the residents the chance for them to gain additional income such as through tuitions, sew-ing and so on. By encouraging local bussiness initiatives among the residents in the neighbourhood, it is hoped that a sharing of local skills and expertise would occur that enables the local economy to further grow and prosper. All through the residents own initiative.

DESIGN RATIONALE: We realise that within the society, the increase in liv-ing costs means that more and more families work multiple jobs to earn more. One of the main intentions when designing the homes for Selasar Niaga is the option of flexibility, namely bussiness flexibility. Medium income families have the option of enlarging the space of the house by means of moving parti-tions. Inside these ‘moving walls’ are built in furniture such as beds and side tables, customised according to the needs of the residents.

BUSSINESSFLEXIBIITY

Movable walls with built in furniture and appliances, built according to the residents desires. Encouraging transformation of spaces into ones for bussiness opportuni-ties.

ENTREPRENEURIAL OPPORTUNITIES

Much of what constitutes our culture involves interaction with the society. Events such as the celebration of a newborn, our myriad of cultual celebrations celebrated yearly means that at all times we are in a constant flux of receiving people vis-iting our homes. Within the confines of social housing we al-low for the creation of such space. Showed above is of a unit dwelling changed to accomodate an Al Quran recital class or turned into a jemaah pray area. An acknowledgement of our cul-ture and its rich tradition

MICRO/MACRO

Selasar Niaga focuses on the rela-tionship of the individual and its surroundings. The real value of a housing program is its ability to connect residents at a macro and micro scale.

From neighbours to the com-munity. Selasar Niaga would act as its own self inititated village, with its own economic activity.

Selasar Niaga is a rein-terpretation and re-adaptation of climatic aspects of the Malay Kampung House taken into vertical scale.

Photovoltaic is the direct conver-sion of light into electricity at the atomic level.Semiconductor ma-terial, typically silicon, is used in thin wafers or ribbons in most commercially available cells.Cuts down on a large portion of the electricity you have to use off the power grid, save some money and help the environment in the process.

The 4-foot T5 has an initial rat-ed light output of 2,900 lumens, This means that savings on instal-lation and long-term maintenance. In addition, the T5 lamp is ideal for low-profile fixtures like cove lighting and display cases. The T5 fluorescent is an efficient alter-native to lighting up any interior or exterior space. It is a verymoney-saving and space-saving ma-terial ideal for industrial appli-cations.

LEDs, or light-emitting diodes, are a form of solid-state light-ing that is extremely efficient and long-lasting. LEDs consist of small capsules or lenses in which tiny chips are placed on heat-conducting material. In addition, since they contain no glass compo-nents, they are not vulnerable to vibration or breakage like conven-tional bulbs.

A bio-swale is a shallow depression created in the earth to accept and convey storm water runoff. A bio-swale uses natural means, including vegetation and soil, to treat storm water by filtering out contami-nants being conveyed in the water.

The solar heat gain through building envelope constitutes a substantial share of cooling load in an airconditionedbuilding. In non air-conditioned buildings, the solar heat gain causes thermal discomfort. To minimise solar heat gain into a building is, therefore, the first and foremost consideration in the design of an energy efficient building.

A design criterion for building envelope known as the overall thermal transfer value (OTTV) has been adopted.
