​GardenTerrace @ Tengah is the 4th development launched within Tengah Garden Precinct. The others being the earlier GardenVale @ Tengah (May 2019 launch) and GardenVines @ Tengah (November 2019 launch) and GardenCourt @ Tengah (November 2020 launch).  GardenCourt @ Tengah is designed by Surbana Jurong Pte. Ltd. Surbana Jurong Pte. Ltd (Surbana being former HDB building and development division) also design Tampines GreenEmerald which is part of November 2020 launch.

Points to ponder
1. This development is located next to a MRT line. To the south end of this site, there's a site reserved for petrol station. It may be blocked visually by the MSCP (multi storey car park), the petrol fume if any, may follow the wind flow direction. These elements may contribute to certain discomfort which homeowners may have to manage their expectation.

2. This development is the 7/8 developments within this new township, there will be plenty of developments to be built within this new town. Homeowners will need to manage their expectation of surrounding construction activity which lead to  noise, air pollution for at least 5 to 10 years time frame.

3.  Both developments are utilizing the standard MSCP (multi storey car park). Therefore, the green spaces have been reduced and construction price for this design typology may not be as high as the previous Garden's development which came with elevated car parks covered by landscape above. Homeowners need to manage their price expectation in the future.

1. Heat have been a sticky issue in Singapore due to its locality and will continue to do so in the foreseeable future due to climate change as well as rapid urban development and redevelopment activities. So much so that the National Research Foundation of Singapore (NRF) (https://www.ura.gov.sg/Corporate/Resources/Ideas-and-Trends/Beat-the-heat) have funded  ‘Cooling Singapore’ initiative, which consist of multi-institutional initiative led by Singapore-ETH Centre (SEC), NUS, SMART and TUM CREATE to look into ways to reduce heat in Singapore since 2017 (https://www.coolingsingapore.sg/). Please take note of the word ‘reduce’ and ‘avoid’. Recently (June 2020), Cooling Singapore has released their findings on ‘Urban Heat Vulnerability Analysis for Singapore’ which also clearly indicates which town in Singapore is currently well ‘heated’! (https://www.research-collection.ethz.ch/handle/20.500.11850/419689)
 
“The UHV index (Urban Heat Vulnerability) is used to measure the effects of physical exposure, demographic sensitivity and socio-economic adjustment parameters. ... The findings help to define areas where heat mitigation measures are needed most, in order to ensure the protection of the population.” – Cooling Singapore  

2. The best way to reduce heat intake has always been trying to minimise the exposure in the first place. In Singapore, we try to avoid heat intake from the west sun (afternoon sun) at all cost due to Singapore being located along the equator, which mean closer to the sun than any other part on Earth. Since Earth rotate at an angle of 23.5 degrees at its axis, North and South facing buildings will have direct west sun exposure as well, the difference is when and how much. Please watch the video here to have a better understanding of the above.
 
3. For this development, our preliminary assessment for west sun impact (2pm-4pm) shown that only 28% of the stacks here will avoid the west sun impact. Therefore, we give a score of 2 out of total 4 for this attribute.

1. The Sun is 147.84 million km away from Earth, that’s more than 3,689 times the circumference of the Earth. The Sun is too far away for us to control its impact. The radius of the Sun is 109x the radius of the Earth. The size of the Sun should speak volume about the difference (if any) in terms of heat intake. On the other hand, wind is closer to home as it happens on Earth. We can either take advantage of it or lose it, we can’t control it. In Singapore, we enjoy prevailing wind during the monsoon season with wind speed of 6-10 km/h. (NEA-weatherwise Singapore). Knowing when and which direction the prevailing wind happens may help to mitigate the heat impact due to west sun exposure.  
 
2. There’s 1 in 16 chances of having the luxury of facing the prevailing wind, which happens 20% of the days in a year (based on MSS’s wind data recorded at Changi station from 2014-2017). The next best option would be 3 in 16 chances of facing the prevailing wind, which happens at least 10% in a year (excluding the above). Mechanical ventilation like air-conditioning can never replace natural ventilation as mechanical mean is mainly contained (meaning the same air will circulate in the same room), while natural ventilation allows air changes between external (outdoor) and internal (indoor) spaces.
 
3. For this development, our preliminary assessment for prevailing wind exposure shown that only 33% of the stacks here will enjoy major prevailing wind exposure which happen more than 180 days in a year. Therefore, we give a score of 2 out of total 4 for this attribute.

1. The Viewing angle is 1 of the 3 attributes which can be determined by the planner or architect who design the development. One can either maximise the viewing vantage or the land yield. Both are mutually exclusive as higher land yield will lead to more building blocks or taller building blocks which will affect the units viewing angle.
 
2. The viewing angle took into account the human eye’s coverage as well as the distance one can see things and identify objects at around 1m height objectively. This attribute will filter situation where the building frontal distance, maybe spacious enough, but the viewing corridor have been greatly reduced due to narrower coverage (reason like the placement of buildings in front which adversely reduced the maximum view).    
 
3. For this development, our preliminary assessment for viewing angle shown that only a meagre 10% of the stacks here will enjoy a good viewing angle. Therefore, we give a score of 1 out of total 4 for this attribute. Please note that we have omitted stacks with good viewing angles and building distance, but looking towards road, monsoon drain, etc. which is not desirable.

1. The noise exposure is the 2 of the 3 attributes which can be determined by the planner or architect who design the development. The planner can plan the town by segregating the land use base on activity, reduce roads, etc. While architect can create buffer to block the adverse effect of noise or use creative way to reduce the surrounding noise impact. As a homeowner, you can make a better judgement by knowing the distance from a potential noise source and how the noise impact will reduce with distance.
 
2. The understanding of noise disturbance in Singapore is still lacking though it’s a prevailing issue in recent years especially in the housing estate. NEA has since identified the 3 main noise disturbance sources as Vehicular noise, Construction noise and Industrial noise. On top of these 3 major noise disturbance sources, we have further identified minor noise disturbance source such as social, mechanical, vehicular (minor), religious, educational, etc.
 
3. For this development, our preliminary assessment for noise disturbance shown a high 6 point. Therefore, we give a score of 2 out of total 4 for this attribute. We assign 3 points for each major noise source and 1 point for each minor noise source.

1. The building distance is the 3rd attributes which can be determined by the planner or architect who design the development. The planner and architect will need to make a judgement call about how to balance the yield as well as ensuring a good building distance between the building blocks. Please note that a good building distance does not translate to a good viewing angle.
 
2. In 2010, URA introduced an industry guide to control the building length to prevent ‘wall-like’ developments. This guideline is mainly to control the distance between the side of 2 buildings rather than the distance between 2 buildings facing each other to break a ‘wall-like’ building blocks. HDB does have an internal guideline to dictate the distance between building facing each other, but it’s not a regulation. 
 
3. For this development, our preliminary assessment for building distance shown that only 44% of the stacks here will enjoy a good building distance (base on buildings lower than 18 storey). Therefore, we give a score of 2 out of total 4 for this attribute. Please note that we don’t make any omission on specific reason like facing road, etc. for this attribute.

We rate this development with an overall score of 10 out of 20.

1. Next, we will post our written analysis for selected stacks at GardenVines@Tengah (Nov 2019 BTO). This written analysis will cover the sun, wind, viewing angle, noise and distance attributes for each of the analysed stacks.
 
2. For homeowners who have selected their unit, you can refer to our analysis to ascertain if you have made the right decision. Should you need to verify our data, you are welcome to join us in our weekly meet the homeowner session where we will show you the model itself and how we build, then analyse it.
 
3. We will do a price analysis of Tengah previous launches. Once the pricing for GardenTerrace@Tengah release, we will make an overall comparison.
