Abstract:
In a tropical climate, passive cooling is difficult to achieve with respect to mass housing design.  A good house design keeps the indoor environment favorable and comfortable during most of the year without the use of any mechanical devices. Terraced houses are typical examples with low comfort problem that need particular consideration. Low air velocity and high air temperature are experienced during the daytime and the wind effect is not well captured, especially in the single sided ventilation. Use of natural ventilation has been increasingly examined as an energy-efficient means to provide thermal comfort as well as a healthy indoor environment. This paper discusses the measurement of thermal comfort in Malaysia’s single storey terraced houses. The thermal environment and comfort conditions were investigated using field measurement technique. The results indicated that the design of single storey terraced houses is not effective in providing natural ventilation for achieving thermal comfort. The microclimate condition surrounding the terraced house indicated very low wind speed. Therefore, modification of the natural ventilation mechanism needs to be manifested and evaluated.

Abstract:
The migration of rural population to cities in Malaysia caused the government and private agencies to built 1.8 millions units of house from 1976 to 1995. Most of the houses are built in rows called terrace houses with openings only on the front and back elevations. The lack of emphasis of local authorities to regulate sufficient ventilation, low outside wind velocity and building design disregard the need of cross ventilation have resulted houses having poor natural ventilation of less than 1.0 m/s air movement in the interior spaces. The ventilation quality could be improved by the introduction of perforated components use by many traditional houses and shophouses in the country. The components include  tophungs of door and window, tall window with adjustable louvers, wall panels and gables. The introduction of these features in the terrace houses will improve the living comfort of urban housing, revitalizing the traditional craft to modern society, and harmonizing the urban dwellers in a multi-racial society by an architectural artifact. Utilization of the panel could boost the furniture and cottage industries which inline with the government policy.

Modification: TERRACE HOME IN KUALA LUMPUR BY JtJ DESIGN

This renovated terrace house is a project by JtJ Design, as featured in Bloesem Blog, shows an abundance of space possibilities despite the limitation of sharing walls between adjacent neighbours. It is not impossible to turn around a run-down, typical terraced house into an amazing home, and JtJ Design did so splendidly. 

The house before the renovation.
From the pictures, it looks like the renovation includes tearing down walls on the ground and first floor, opened gable room, a skylight (!) and additional second floor. 

Family room on the ground floor


Amazing idea on running away from ground floor kitchen! And bare-it-all structural elements. The combination of concrete, timber and stainless steel kitchen element creates an industrial look and easy living.

Living room, kitchen and dining room on the first floor

Abstract:
Cultural-ethnic landscape symbolizes the belief and cultural values of an ethnic group living in a community. The landscape is an expression of people's idea and work; illustrating intrinsic understanding and relationship of people to their fellow beings and environment. Such landscape  is significant to the human community development and more challenging to establish it in a multi-ethnic society such as terrace house neighbourhood in Peninsular Malaysia than in homogenous society. 

This research investigates the characteristics of terrace house gardens from three ethnic groups, namely, Malays, Chinese and Indians. Through inventory and analysis of 23 neighbourhoods in Peninsular Malaysia, it is found that 52% of the terrace houses have gardens. The design of garden and its features are partially influenced by ethnicity belief of the residents. The differences are in selection of plant species which are determined by the religious belief and ritual rite of the ethnic group. In hierarchical importance, the plant species are planted in the house garden for five reasons or uses, namely (i) decoration, (ii) food, (iii) medicine and cosmetics, (iv) ritual, and (v) provision of shade.

Abstract:
The ubiquitous terrace house is still the most popular housing type in the country. Terrace housing has long been considered the densest form of  property development and in Malaysia has become the stereotyped form of accommodating the masses. However, its design has been plague with various issues for decades. It has been associated with bad design, heat collector, safety issues and unsightly renovations. In contrary to the tropical architecture with sun shading devices, ventilation, openings and the use of local material such as timber, terrace houses have been designed as masonry and reinforced concrete boxes fitted with air conditioning. The modern day terrace house whilst designed has perhaps overlooked one of the most important elements of a tropical house that is the raised floor. The traditional raised floor design involves issues such as ventilation, lighting, thermal comfort and social aspects.  

This research intends to explore the various issues mentioned above and proposed to uniquely develop a new design for in-house habitation as well as providing for an aesthetically pleasing look. It suggests a possible and promising way of increasing the livability of terrace housing by the means of a raised floor and at this stage it is still in the experimental stage.

Articles: EARLY HISTORY OF THE TERRACE

Reference to this article: Early History of the Terrace

New Straits Times, February 19, 2005
by Dr Gwynn Jenkins

Letter to the Editor:

I REFER to your Focus article in PropertyTimes of Feb 12, titled "Evolution of terrace housing".

One of Malaysia's earliest urban settlements, which used brick construction and row terracing, was Georgetown in Penang.

In the English cities of the Georgian era that evolved rapidly during the economic boom of that period, such as Bath, the concept of speculative building in soon-to-be fashionable areas had caught on. Inevitably, speed of construction and economy materials were essential for maximum profit.

Hence, houses were built in rows with shared party walls dividing neighbouring units. Many of them were badly built and the owners now spend many thousands of pounds conserving these "famous" terraces of Bath (so, there's nothing new about speculation and poor quality).

Very soon after the British East India Company set up an administrative base in George Town, Chinese families arrived. They too preferred the economy of shared party walls and introduced rows of shophouses alongside the simple Indian shophouses and European godowns.

The Europeans, like the indigenous Malays, tended to prefer the bungalow housing form. Penang's Little India today clearly identifies the urban shophouse morphology. This building form predominated the streetscape as George Town grew.

However, by early 1900s, after outbreaks of cholera, plague, malaria and small pox, due largely to unsanitary conditions and overcrowding, building ordinances were introduced, following those Britain.

Back lands were created for night soil collection and the houses were set back from the street, behind a garden wall. Built purposefully for housing and not a commercial mix, they became known as the terraced house.

Although the tripartite arrangement of the front door flanked by windows continued and the five-foot ways were habitually incorporated, they were no longer a public walkway. The front garden gave way to the car porch and the five-foot way to overhangs, balconies and other shading devices.

One element which remains prominent, particularly in Penang's terraced house, is the interior layout that was guided by feng shui or vashtu shastra -a clear indication of their roots- that are not found in the Georgian model, from which they only partly share their origins.

Terrace houses have coloured the Malaysian urban landscape for as long as most of us can remember. Over the years, the terrace has grown into one of the more successful residential concepts in the country, and has come to be recognised as the principal form of housing for the middle-income group.

Today, terraces are probably responsible for housing the largest segment of the nation's population, having become an integral feature in any developed or emerging residential locale.

Blossoming as a popular residential concept in the 1970s, the origin of the Malaysian terrace house can be traced to humble beginnings in the post-Independence era of the late 50s and early 60s. 

Kuala Lumpur, capital of the young country, was growing rapidly, giving rise to many satellite townships that were primarily industrial districts, around which grew an expanding population of blue collared workers requiring a simple and basic form of housing near their places of work. 

According to architect Puvan J.Selvanathan, the concept of linked houses, a successful form of low-cost housing in the United Kingdom, provided the ideal solution as it allowed for large of families to be clustered close to their workplaces by maximizing the land area.

"The growth of corridor in those days was very much the stretch between KL and Port Klang, along Old Klang Road. This stretch spawned many satellite districts. 

"A prominent example would, of course, be Petaling Jaya, where in places such as Section One, you still see evidence of some of the earliest forms of this housing type," he said.

According to Puvan, the designs for these houses, primarily suited to temperate conditions, were imported wholesale from England. As a result, some of them had somewhat awkward features for an Asian home, such as chimneys.

"Yes, it really was quite bizarre! But this is just evidence that the concept was a borrowed one as Malaysian architecture hadn't developed an identity of its own in those days," he said.

Though simple in nature and basic in design, Puvan noted that these buildings were solidly built, with sound foundations and brick walls - which is why many of them are still standing today. 

Improvements in the design of terraces began taking shape in the 70s, together with home ownership demands from a rapidly growing middle-class urban group.

This was the start of the mass housing effort, and with blue collared workers taking to apartments as a consequence of rising land cost pushing them upwards, a new concept was conceived for terrace housing in communities close to commercial hubs. This appealed to the emerging middle-income population, firmly cementing the terrace house as a "middle-class phenomenon" that brought about thriving new communities.

"During this time the terrace moved up the economic and social scales, evolving into the preferred housing form of the middle-income earners. The Bangsar model, in fact, set the template for terrace housing development in many other States of the country," Puvan said.

Terraces remained popular throughout the 70s and many suburban communities in the Kland Valley, as well as throughout the country, began to use this concept as their primary residential product. 

Noticeably, in established communities such as PJ, which began to transform from an industrialized community into a more affluent neighbourhood, developers began to offer more spacious terrace houses in an attempt to lure buyers to the satellite township. Evidently, this strategy worked.

"In my opinion, houses were just better built in those days. There was an unmistakable quality, with good foundation, good structure and decent finishing," said Puvan, adding that common features such as walls with ventilation holes, spacious rooms and living areas proved a lot of thought was put into the design of these early terraces.

Unfortunately by the mid-80s, at the height of the housing boom, the rapid development of houses began to take its toll and quality became the victim of pace.

One key reason for this was Federal policy at that time, which called for developers to construct large numbers of low-cost houses within a certain time frame (Fourth Malaysia Plan, 1981-85). This fuelled the rush to build houses, as developers had to split their attention between building low-cost units for the Government -a non-profitable activity- and building as fast as they could for profit.

"It was also very much a seller's market at the time, with many developers just churning out houses, sparing little thought to the design layout or quality of the product," Puvan said.

"Suburbs such as Ampang were booming, but sadly, as many of the residents there will attest, the terraces built at that time were far below far below par as far as quality was concerned.

"Rooms were disproportionate ... some were the size of a corridor, floor plans were poorly laid out and one would find very dangerous-looking staircases in many of these homes," Puvan said. 

Along with poorly planned interiors, the foundations of these late-80s houses were also suspect. Today, he said, cracked ceilings and broken walls are not uncommon with terraces of that period found in Ampang.

However, Puvan said not all developments of that period were bad. Relatively decent houses were built in areas such as Subang Jaya and many of the responsible developers of the late-80s and early-90s have moved on to become some of today's most trusted names in property.

Ironically, even under a callous development environment , the terrace concept managed to climb further up the ladder of social acceptance. This could be attributed to the introduction of condominium living for the middle-income group, which predominantly appealed to the younger people. Terraces now began to cater to the more matured and affluent upper-middle class.

As a result, by the mid-90s, buyers of terrace units were a more sophisticated and demanding lot. Meeting the demands of this market eventually proved to be a catalyst for the revival for the revival of quality in this type of housing.

Another important factor that helped improve the overall development environment was that in 2000, the Government decided to take back much of the burden of building low-cost houses. This eased pressure on private developers, allowing them to concentrate on and improve their more profitable sources of income.

Improved sentiments in the industry, coupled with emergence of branding, spurred a renaissance in the construction of terrace houses, Puvan said.

"Buyers were getting smarter, but so were developers. They knew that they were now dealing with more wary customers as well as a more competitive market. In answer, new marketing and building concepts were fashioned to appeal to buyers and to get ahead of the competition."

Today, terrace houses are available in numerous forms, from small and compact starter houses to gated-and-guarded communities.

"Learning from mistakes of a past era and realising the effect product quality can have on the reputation of a developer has brought about improvement in the quality of construction by leaps and bounds," he said, adding that modern day terraces have also seen improvements in interior planning.

"If you look at some of the floor plans of recent developments, you'll find that most are pretty well through out. As opposed to the 80s, rooms once again are spacious, living spaces are roomy and overall, even in the more compact terrace offerings, there is better planning and usage of space. The comfort of the dweller has obviously been taken into consideration in designing these houses."

Puvan expects this positive trend to continue, saying that Malaysia is an aspirant society that is getting increasingly discontent with mediocrity.

"With development on the whole in this country beginning to set benchmarks for the region, I can only imagine that the terrace concept will also continue to evolve positively, achieving new heights and setting new benchmarks in the years to come."

Paper on Terrace Housing: THE IMPACT OF WIDER FRONTAGE DESIGN OF LOW-COST DOUBLE STOREY TERRACE HOUSE (LCDSTH) TO AIRFLOW AND NATURAL VENTILATION IN MALAYSIA

Abstract:
This thesis presents the result of an analysis which was done to predict the impact of wider frontage design of low-cost double-storey terrace house (LCDSTH) to airflow and natural ventilation in Kuala Lumpur. The existing LCDSTH has narrow frontage and deep plan which necessitates its internal planning with partitions to divide the spaces and arranged the rooms to have single-sided openings. These arrangements have extremely limited cross-ventilation potential and caused discomfort to occupants.

Due to the availability of natural ventilation from the prevailing wind in Malaysia, the LCDSTH design could be manipulated to enhance the natural ventilation to flow into the living spaces and gives cooling effect to ameliorate occupants' thermal comfort. Predictions of the mean internal air velocity in the existing and proposed LCDSTH are used to identify the potential plan for improving thermal comfort.

Computational Fluid Dynamic is chosen due to its capability in fluid dynamic studies. A specific software named FLOVENT is used to predict the internal air velocity by simulation the simplified building configuration of the existing and proposed model of LCDSTH. The outcomes of the simulated results are then compared using the graphic velocity vectors and contour from FLOVENT and also from the mean internal air velocity graph.

The results show that although the proposed design with wider frontage, shorter depth plan and different building height in a staggered and checker board pattern position give the best solution as compared to the existing plan, it is not significant enough to provide to the most preferable air velocity values of 1.0m/s for thermal comfort at every position of each unit in a row of LCDSTH. However, it does improve the performance of the mean internal air velocity in comparison with the existing double storey terrace house that has the design of narrow frontage and deep plan.

Abstract:
This paper presents the initial findings of a study on the spatial modifications of fifty houses by homeowners in the Klang Valley area. Using a standardized format, various attributes consisting altered spaces and features were compiled and examined. It appears that certain features of the houses including the kitchen, bedrooms and bathrooms were desperately altered. People have used their creativity in altering the spaces beyond the original intentions of the architect. To some extent, the findings indicate that the current model for providing houses has shortcomings in addressing the need to satisfy the aspirations of individual family to living.

Getting Inside: A LOW COST TERRACE HOUSING IN MENTAKAB, PAHANG

The initial design of this low cost terrace housing was a kitchen connected to the living room (usually a dining area separates and mediates the function of two spaces however this house has no dining room) and a bathroom on the ground floor with two bedroom on the first floor. The owner had taken the initiatives to fully extend the rear yard into a kitchen, which adds an additional space for dining between the kitchen and living areas, but unfortunately, keeping the open plan concept. 

Entering the living area, one can straightaway see the dining and kitchen areas (and the back neighbour's door, even sometimes, the living area of the back neighbour when the door is open). 





View from the kitchen, residents can see the front neighbour, giving less privacy

As most of terrace housings are let by the owners to renters, not much can be done to adjust this situation without doing physical modification. The most economical solution is to use curtains to obstruct the views and keeping the privacy of the residents. 





Drying Laundry In Terrace Housing

Unlike drying laundry mechanically using dryer as normally used by the Westerners, most Malaysians dry their laundry traditionally under the sunlight, maximizing the abundance of sunlight hours up to 7.4hours (Climate Temp).

In terrace housing areas, this practice is done either at the front yard, rear yard, front gate, or balconies.
