Tampines GreenOpal is the 2nd development after Tampines GreenGem which will populate the Tampines South region. 3 more parcels in the vicinity have since been awarded for design development. Tampines GreenOpal is designed by Ong & Ong architect (former Singapore president, Ong Teng Cheong’s architecture practice currently run by his son) which also designed the February 2020 BTO, Toa Payoh Ridge.

Points to ponder
1. Homeowners need to manage their expectation on the definition of 'canal'. While the park connector claimed to be designed based on NParks ABC features, Bedok Canal is not part of NParks ABC initiative.  In short, compare Bedok Canal to Bishan-Ang Mo Kio Park. 

2. This development is utilising PWCS (pneumatic Waste Conveyance System). While this new approach will save manpower on refuse collection as well as reduce surface area to be used for road access to individual refuse center, complaint has been received from Yuhua's residents which pioneered this method. High end private condominium at Marina Bay have also suffered some 'misfortune' which causes an unpleasant smell from the refuse chute.

"Soon Ching provided a really concise and well thought out explanation on his background and what he is offering. Really good service in my opinion, considering the detailed analysis. He is able to even look into the flat using 3D model and provide you with the view that you will have from your unit, how the sun will hit you at different times etc.

Apart from that, you can also give him whatever specific request you might want to know about. For eg, if you don’t like a unit near rubbish chute etc. He is able to tailor each report to each individual home owner, which is a huge plus point for us.

Wind, sun and view - he provides quite a detailed report on it as well. Payment is made in 3 stages, which gives us peace of mind as payment is made at different stages of receiving deliverables from him.

All in all, a very genuine guy with a wealth of experience, looking forward to securing the best home for us with our queue number and his expertise." ​

Written Analysis (selected stack) ​

Block 963B
stack 622
1. This stack is facing North West. This stack will have up to 5 months of 3pm west sun exposure. 

2. Based on weather data collected by NEA from 2014 to 2017, this stack will not have direct exposure to prevailing wind potential. 
This is due to main façade being parallel with the higher chance of prevailing wind potential. Thus, no potential of cross ventilation. 

3. This stack will have a viewing angle of 25/120 (viewing distance of up to 25m with viewing coverage of 120 degree) measured from main facade.
This stack has reduced viewing angle due to anticipated future health and medical care facility to the North which will halve this stack’s extended viewing angle. Unit higher than the facility will have better viewing angle. We will advise separately for units higher than the facility. 

4. This stack is directly facing/ within close proximity (75m radius for Major source and 38m radius for Minor source) to Construction source (future).  
The above will mainly come from the construction of the future health and medical care facility. 

5. This stack will enjoy a building distance of up to 50m (distance being measured perpendicularly from the main façade to the nearest opposite block). 
1 point being deducted from the building distance attribute due to viewing angle of this stack have been reduced. 

6. Lift ratio for this block is at 1:48. This ratio is within the comfort level of recommended 1:40-60. 

7. This stack will have up to 35m from the nearest lift. 
​
stack 630
1. This stack is facing off North towards North West. This stack will have up to 3 months of 3pm west sun exposure. 

2. Based on weather data collected by NEA from 2014 to 2017, this stack will have direct exposure to prevailing wind potential from North (N). 
To enjoy the above prevailing wind exposure, units will need to be higher than the future health and medical care facility. We will advise separately.

3. This stack will have a viewing angle of 25/120 (viewing distance of up to 25m with viewing coverage of 120 degree) measured from main facade.
This stack has reduced viewing angle due to anticipated future health and medical care facility to the North which will halve this stack’s extended viewing angle. Unit higher than the facility will have better viewing angle. We will advise separately for units higher than the facility. 
1 point being deducted from viewing angle due to main façade facing towards the main road/ future construction site/ health and medical care facility which is less desirable than lake or green area.

4. This stack is directly facing/ within close proximity (75m radius for Major source and 38m radius for Minor source) to Vehicular source (Primary road) and Construction source (future).   

5. This stack will enjoy a building distance of up to 40m (distance being measured perpendicularly from the main façade to the nearest opposite block).
1 point being deducted from the building distance attribute due to viewing angle of this stack have been reduced. 

6. Lift ratio for this block is at 1:48. This ratio is within the comfort level of recommended 1:40-60. 

7. This stack will have up to 35m from the nearest lift. 

8. This stack is located next to an open staircase (non-residents can access the staircase anytime without restriction).  

"Highly recommend Hausanalyst's services. Soon Ching (hausanalyst) is extremely knowledgeable and passionate about helping people find their dream homes. He was able to articulate all the important factors when choosing a house (sun, wind, views, sound etc), with ample research and industry experience to back up his insights. We were genuinely surprised by the level of detail he went to in our calls with him. His 3D model allowed us to visualize the views from our shortlisted units, very valuable information we could not have obtained anywhere else. After seeing the 3D model we actually changed our decision on the final unit. Furthermore, Soon Ching (hausanalyst) was very responsive and sincere, staying up late with us the day before our appointment to help validate our choices and even gave us live updates on the units taken near our appointment time. Top notch service. After our experience with Soon Ching (hausanalyst), we felt like $xxx is a real bargain as we got so much value that helped us make an informed decision for one of our biggest life purchases."

Highly recommended. We are a couple who balloted for an uncompleted SBF flat. Soon Ching (hausanalyst) was able to help us visualize ideal units clearly through his 3D modelling. The info was something we will never able to obtain, even by walking the ground. We also felt very assured with Soon Ching's (hausanalyst) guidance as we could feel his sincerity in putting our best interests at heart. 5 stars.

Pricing Analysis

Rationale
1. The purpose of analyzing the pricing is not about projecting the future trending, rather it’s about looking for a sweet point to enter/ buy.
2. Once the sweet point being identified, homeowners can make reference to hausanalyst scoring for each stack/ unit to determine which is the best unit to select.
3. Quantum pricing or the total amount of the unit is not a good indication to find a sweet spot as developments always came in different sizes even though it’s of same room type. (i.e. A 4-room may come in 92sqm, 94sqm or even 96sqm) The best indication should be down to its basic unit which is per square foot (psf) rate.
4. Comparison between launch price and resale price is done by classifying prices in max and min based on selected levels (as being used by HDB to record resale prices). Analysis output presented in percentage differences to allow easier understanding in terms of price movement and quantum. 

Data set
1. Tampines North 4-room and 5-room launch price which summarized the max and min prices of 8,568 units launched since Tampines GreenWeave (2015) till Tampines GreenCrest (2020).
2. Tampines GreenLeaf 4-room and 5-room launch price (2012) vs resale prices (Dec 2020). The charts summarized a total of 384 units of 4-room and 320 units of 5-room with resales records of 87 (22.6%) units of 4-room and 66 (20.6%) units of 5-room transacted to date.

Observation
1. (Tampines North launch price) Prices for 4-room and 5-room have move upward in tandem with time since 2015.
2. (Tampines North launch price) Units at GreenGlen, GreenGlades and GreenCrest have shown steep price increment.
3. (Tampines GreenLeaf) A 4-room have recorded more than 75% return as compare to a 5-room of no more than 67%.
4. (Tampines GreenLeaf) Highest level is not the best investment when anticipating highest return. Higher level also not necessary translate to higher return.
5. (Tampines GreenLeaf 5-room) Buy very low and sell very high (higher than max price transaction) do happen.

Conclusion
1. (Tampines North launch price) Prices upward movement consistent with a typical master development strategy whereby later phases tend to have higher price point. The higher Tampines GreenCourt’s psf price is partly due to marked up pricing (immediate proximity to the central park), huge development size (consist of 4 parcels in a single launch), PPVC technology (being introduced for the first time in public housing). Being first in PPVC also entail unknown risk, therefore higher price buffer construction risk.
2. (Tampines North launch price) Smaller parcel, supposedly less crowded and more privacy. Location is nearer to the future Tampines North MRT station.
3. (Tampines GreenLeaf) There’s only so many buyers can pay in an inflated market. Buyers may have pushed for higher price for better units, but short of funding going for a 5-room. The difference between the 2 translate to almost extra S$100k.
4. (Tampines GreenLeaf) Data speak volume.
5. (Tampines GreenLeaf 5-room) Miracles do happen! If the unit has good attributes, it’s not surprising the price can fetch higher return. On the flip side, one can argue that this anomaly may be due to higher median price and the resale price is a translation of that higher median price.
