The Cluster Townhouse

THE SINGLE STOREY TERRACE HOUSE

Single storey terrace houses were the most common house-type for rural areas and small towns. In urban areas where land has become expensive, single storey houses are not common any more for new developments. Typically, they occupied 20’X70’ plots of land and a few years ago would be priced at RM110,000 and below. However, they are expensive to build with a big area for footings and roof, a large party wall, and low density. Worse, they are perceived as less prestigious than two storey houses.

Now with building costs much higher than a few years ago, even developers in rural areas are shunning the single storey houses. The ones that get launched are also getting more expensive, leaving a gap in the supply of new houses in the RM80,000 to RM130,000 price range that used to be served by the single storey terrace houses.

THE TOWNHOUSE AS A CHEAPER ALTERNATIVE TO THE SINGLE-STOREY TERRACE HOUSE

For the solution, we looked to an existing type of residential unit in Malaysia which is called a “townhouse”. Introduced in the 1980’s, it is actually a large terrace house with different owners on the ground and the first floors. This relatively new building type, is for people who can’t quite afford a terrace house, but do not want to live in flats.



The Terrace Townhouse: Townhouse at Bayu Permai in Rawang; from from GM Build website



The terrace townhouses usually have only 22’ or 24’ frontages and this is too tight. The street fronting the townhouses has gate after gate along it: there is no space at all along the street for a second car, or indeed for any visitors. There is also too little external walls for proper ventilation and lighting for the rooms within them: the room layout gets very contorted as the various rooms compete for space for windows.

THE SEXTUPLEX TOWNHOUSE

We came up with a cluster version of the townhouse. You saw a preview of it in north Johor in the last chapter "A Big and a Big Site". What used to be a sextuplex house was divided into upstairs and downstairs units. These townhouses can fill an important niche in the market: while the usual kinds landed property – terrace, semi-detached and detached houses – are becoming more unaffordable for many people, they are not yet ready to accept living in apartments. At about 1000sf built-up area, these would have the same built-up area as fsingle–storey terrace houses. They are cheaper to build than single storey houses because they have more shared walls, floors and roof, and each unit takes up a smaller piece of land. I believe that they should be priced 10% cheaper than single storey houses.




The Upper Floor Unit



The Lower Floor Unit


The new Honeycomb Townhouse designs are an improvement on the terrace townhouses now already found in city areas.


Perspectives of the Sextuplex Townhouse

The Honeycomb Townhouse has the advantage of being a corner unit with a garden to the side. There is more space for windows, and this makes the layout easier – there are enough external walls to provide windows for all the rooms. The Honeycomb Townhouse also has at least 30’ frontage. This means that after providing for the gates to the car-porches of the lower and upper floor units, there is still another 10’ to the side. In addition, the Honeycomb courtyard would mix quadruplex and sextuplex units, but only the sextuplex units are suitable for conversion to Townhouses (the quadruplex units have frontages which are too narrow). So the mixture of quadruplex and Townhouses becomes less crowded than a street of terrace townhouses.

There is another important advantage – the terrace townhouse has a rear garden for the ground floor unit but none at all for the first floor unit. But the Honeycomb Townhouse has a front garden for the upper floor unit and a rear garden for the lower ground unit!

THE QUADRUPLEX TOWNHOUSE

There is also a rectilinear version of the Townhouse. The layout is much simpler. It is also possible to have a higher percentage of townhouses in this version because all the cluster blocks except the corner access ones can be converted from quadruplexes to Townhouses.


The developer, the Seri Pengkalan Group, which had experimented with the small Honeycomb project in Merlimau Melaka had a bigger problem to solve.

In Melaka, the level of affordability is low; the most popular product was the single storey terrace houses. However, as land prices and construction costs inched upwards, developers could only extract marginal profits from the terrace houses.

This was a problem for Sei Pengkalan too.

For their development just outside a small town, Alor Gajah, about 45 minutes from Melaka city. For some time they experimented with one and half storey terrace houses – products that they could sell at a higher price but which are supposed to be only slightly more expensive than the purely single storey house. However, providing a staircase that can take up 100sf that serves just a few hundred square feet in the attic space is inefficient.

I was able to convince them to build two storey cluster houses instead that had box-like plans that were easy to build. A simpler, cheaper version of the cluster houses at Bernam Jaya was adopted and they were priced attractively RM240,000. These, together with semi-detached houses (also similar to the Bernam Jaya ones) proved easy to sell. There were enough people in Alor Gajah who were able to afford the houses.

The harder problem was that there was still a large market for the market segment that single storey houses used to occupy – houses that cost below RM200,000 down to RM120,000. The State of Melaka by that time had instituted new rules that require a portion of houses to be sold at RM150,000 or less. To overcome this problem we proposed the cluster townhouse.




KASA HEIGHTS TOWNHOUSES

In Alor Gajah, we had designed 288 units of cluster townhouses. Due to the constraint on the selling price, the client insisted the buildings be laid out along straight lines to minimize cost. Still, priced at RM150,000 there was a considerable amount of trepidation on the part of the developer. After all, the terrace townhouse had proven itself to be unpopular; not too long ago, at RM150,000, purchasers could buy single-storey terrace houses.




Nevertheless, the cluster townhouses proved themselves to be an acceptable alternative, and all the units were sold out in three months.

Honeycomb Housing on a Rectangular Grid in Bernam Jaya

There were many competing housing projects around Bernam Jaya in Selangor and in Tanjung Malim in neighbouring Perak, but the market leader was Proton City, a high profile development next to the large Proton car-making factory which was designed according to town-planning concepts that were new at that time. It was a gated development with a mix of detached, semi-detached, terrace houses and low-rise apartments arranged around a very generous open space which included a lake which also served as a retention pond. The roads were wide with footpaths and well landscaped. However, this was a high-end project with pricing to match.

PKNS had to pivot away from competing with the low-priced conventional housing projects, but instead to challenge Proton City in the medium-high price category.

The two types of products that was proposed were wide frontage cluster houses and semi-detached houses. The selling price of the main product – the double story cluster house - was fixed at only RM290,000 – RM320,000) compared well with competing terrace houses. As for the Semi Detached houses, which made up 20% of the overall number of units, they were priced from RM350,000. Both these houses have proven very desirable.

The cluster house products were designed to be alternatives to the ubiquitous 24’x70’ terrace houses in terms of pricing, but with several plusses:
  • ·         Seen from the front, the cluster houses look like semi-detached houses
  • ·         The frontage at 42’, wide enough to park 5 cars side by side, dwarfs that of the terrace houses
  • ·         The side and front gardens to each house make it very spacious
  • ·         Compared to narrow frontage terrace house constricted by party walls on its long sides, the cluster houses had more external walls to place windows: in fact the main rooms are able to get cross lighting and ventilation.
  •            The concrete porch allowed the possibility of being turned into a large balcony, adding to the feeling of spaciousness.


Houses with 42' wide frontages, more than double that of many terrace houses,
from RM290,000 (USD70,000)
Cluster houses have more external walls for windows

As for the semi-detached houses, they were placed on a footprint only slightly larger than the cluster houses, and had built-up areas that were smaller than most other double-storey semi-detached houses. This was to create a particularly attractively priced product that was easily sold.

On top of the unique features of the cluster and semi-detached houses were the Honeycomb that matched the social quality of the hexagonal Honeycomb albeit at a lower density.

Overlooking the main entrance into the Honeycomb project
Parents can easily oversee their children playing in the courtyard in front of each home. There are many ‘eyes on the street’ that can deter unwanted behaviour. Danger from traffic would be much reduced. Large trees can be planted in the courtyards to shade, cool and beautify the outdoors - suited for recreational and social use, not only for children but their parents and grandparents as well. A child friendly environment is friendly to people of all ages.

The courtyards also provide space for communal events like weddings and festive celebrations where residents can set up tents. Courtyards are also linked to each other and to the main centralized green area.
Parents can easily oversee their children playing in the courtyard in front of each home
Having to provide for circulation space makes up a considerable portion of the cost of housing. For landed property roads can take up 40% of the total development land. In our case it was only 37% and this saving in roads allowed us to provide more green open space area than the planning rules required.

Moreover, by integrating circulation space into a courtyard space surrounded by houses, the advantages of a small neighbourhood are achieved while at the same time reducing the amount of space that is given over solely for circulation. The courtyards do allow for car and/or pedestrian access, but that circulation area is part of a bigger courtyard space that allows for children’s’ play, social interaction and communal events.

The design of the layout achieved almost 10 units per acre and sellable land at 50% of the total development area which respectively matched and exceeded the figures achieved with conventional terrace houses. On this 20 acre site, we were able to build 207 units of which, 20% were semi-detached houses and the rest, cluster.

A bird's eye view
Together with the cost-saving features of the external layout, the internal layout of the houses were also designed to be especially efficient with low built-up area. Both these efficiencies kept down the cost to that of an equivalent terrace house development and helped the developer’s bottom line. 
All the units will be handed over to buyers this year and the construction of new phases in Bernam Jaya with higher-end houses indicate that the pivot to more profitable products by PKNS was successful. 

We're now working on a new Phase with a new Honeycomb "Zero-Lot" layout.

3.2 A Pioneer Project in Nong Chik

A conventional layout with terrace houses and bungalows had already been prepared for the site.

Dissatisfied with the conventional proposal, he asked us to prepare an alternative layout which we promptly did. Our layout had more units and a higher sales value than the previous one. With both the narrow and wider commercial aims of the developer met, our layout was adopted.

For this Joint Venture between the State Government and a private developer, we had to present the proposal to the Chief Minister and the State Land Exco to get their support as the land-owner and co-developer. Having gone through this stage, the Planning and Building Approvals went through the normal procedures.

Figure 3 Bird's eye view

At last, the first Honeycomb project!

In this layout, small groups of houses are laid out around communal courtyards in interconnected cul-de-sacs (figures 3-5). Three new types of houses - the quadruplex, sextuplex and duplex houses – were introduced as alternatives to terrace houses.

According to a commentary: “…small groups of houses are laid out around a communal courtyard like friends sitting around a table. This makes it easy for neighbours to get to know each other. Strangers entering a cul-de-sac would feel that they were entering a semi-private area, and furthermore, they would be easily recognized as strangers by the residents. It’s like that in the kampong, people know each other; it’s not uncommon to politely challenge a stranger by a simple greeting."

Figure 4 Typical Honeycomb cul-de-sac

"The loops and bends in the roads leading to the houses, less than 25 metres in any straight stretch, slow down cars to a walking speed. Furthermore, with the Honeycomb layout, parents can easily oversee their children playing in the courtyard in front of each home. Indeed, there are many ‘eyes on the street’ that can deter unwanted behaviour.”

“Giant, fast-growing trees will be planted in the courtyards to shade and cool the outdoors. All these factors will encourage parents to let their small children play outside. The courtyards not only serve as a recreational area but are also suitable for weddings and any other community events.”

Located by the side of a hill and flanked by existing houses, the earthwork levels within the site were very much constrained and retaining walls had to be built. However, the major parts of the retaining walls were built on the party walls of the blocks of houses, largely hidden from view.

Figure 5 A half-courtyard

The houses launched in Phase 1 of the project were priced between RM295,000 and RM458,000. There were many teething problems in this project but the developer did not falter in overcoming all the obstacles. The first part of the project completed in late 2013 and the second in 2014.


Honeycomb Houses

The terrace house has been designed and redesigned so many times that there is not much room left for innovation. In contrast, the polygonal cluster houses created by the Honeycomb layout have little in the way of precedence, especially in having to deal with 60 and 120-degree angles. The houses in this Nong Chik project comprise mainly quadruplex, sextuplex and duplex houses.

Figure 6 A Quadruplex house from the courtyard looks like a semi-detached house.



Figure 7 The Quadruplex floor plan
In the quadruplex, a residential block is split into four linked units, with a pair of houses facing one courtyard and the other pair facing another courtyard on the opposite side. Thus, approaching this house from one cul-de-sac, it gives the impression of being a semi-detached house. It has 1660sf (154.2sm) built-up area sitting on a minimum of 1440sf (133.8sm) of land and was priced in 2010 from RM297,500.

The living room and dining together with a kitchen, utility, store and bathroom are located on the ground floor, whilst a family room upstairs leads on to a Master Bedroom, two more bedrooms and a bathroom. The Master Bedroom has an ensuite bathroom.

Figure 8 A Sextuplex house has the appearance of a semi-detached house
Figure 9 The Sextuplex floor plan
In the Sextuplex house, a residential block is split into six units separated by party walls, with a pair of houses facing one of three courtyards. Thus, approaching a sextuplex from any one cul-de-sac, the house has the appearance of a semi-detached house.

It has 2170sf (201.6sm) built-up area sitting on at least 2070sf (192.3sm) of land and was priced from RM388,500. The living room and dining together with a kitchen, utility, store and bathroom are located on the ground floor, whilst a family room upstairs leads on to a Master Bedroom with an attached bathroom, two more bedrooms and a bathroom.


Figure 10 A Duplex house from the front looks like a detached house
Figure 11 The duplex floor plan 



The duplex house is a semi-detached house which is linked back-to-back rather than side-to-side as is usually the case.

The living room and dining together with a wet and dry kitchen, bedroom 4 and bathroom are located on the ground floor. On the first floor is a family room that leads to a Master Bedroom with an attached bathroom, two more bedrooms and another bathroom.

It has a total built-up area of 2440sf (226.7sm) sitting on 2290sf (212.7sm) of land and was priced at RM508,000.

Squares Housing in Hulu Selangor - Type C Quadruplex

I am surprised that it's been ten days since the last post! I've been busy again.
But good news - all 46 units of the first phase of the Bernam Jaya Squares project have sold out...
This is more information about this scheme:

TYPE C QUADRUPLEX 

In this development are quadruplex and duplex units. Below is one of the quadruplex housetypes.



The proposed quadruplexes have large front yards. Each lot is 42’x 42’ such that the house can be 32’ wide.and 22’ deep



Unlike terrace houses, the 'Squares' house is not confined by their neighbours on each side. Every unit is a corner unit with more visible external walls for windows to provide light and ventilation.





The 'Square' layout is based on a patent pending concept of a cluster layout design which creates a neighbourhood that is:
  • safe
  • friendly, and
  • green


This is the layout for the following Phase 4B



This is the area breakdown for this housetype:

Squares Housing in Hulu Selangor

I'm interrupting my series of posts on Terrace Housing with some relevant breaking news...

This weekend will see the launching of a new housing scheme in Hulu Bernam in the north of Selangor, just across the border from Tanjung Malim in neighbouring state of Perak. This is my first opportunity to showcase a rectilinear version of my original Honeycomb layout.



This idea came about in response objections from builders who would only be comfortable with rectangular shapes and 90 degree angles. But it is also an attempt to find an acceptable form of the Honeycomb cul-de-sac layout that is acceptable to the conservative section of the the Chinese community worried about "feng shui".. Here,
  • there are no dead-ends
  • all houses and rooms are rectangular
  • the overall lot sizes are square
  • the houses have a wide frontage
The 'Squares' housing concept aims to improve the external environment of a housing neighbourhood and at the same time increase green area by reducing the area of surfaced roads whilst reducing traffic to ensure a safer residential area for children, cyclists and pedestrians.






The houses would face a small community park with small birds and large shady rainforest trees, providing a safe playground for young children and encourage sociable neighbourhoods.

This housing concept has been recently adopted by PKNS (Selagor State Economic Development Corpration). This project will offer a variety of affordable alternatives to terrace houses normally available to Malaysians -  from RM260,000 (USD85,000) to RM360,000 (USD120,000).





8 to 22 houses are arranged around a courtyard, essentially like friends sitting around a table, forming a “Village Square”. There are numerous places for children to play. A place friendly to children is friendly to all. The residents would know their neighbours and strangers stand out. Cars automatically slow down in the cul-de-sacs and through traffic is eliminated.







Each house faces a park planted with giant, wide canopy trees that cools the external environment and provides food and habitat for birds and small animals.






The courtyards are linked by footpaths that encourage residents to walk. The proximity of such a pleasant social space to every resident – young, old or disabled – is conducive in fostering a sense of community in this housing scheme.

 Have a look at the layout. You will find quadruplex and duplex units mainly arranged around courtyards:
