"Prime Mansion Sawasdee" is one of the excellent options for a new beginning in the city. It is a residential development with a small number of units; therefore, it is not crowded and offers very good privacy. Transportation is also convenient; it is close to Phrom Phong BTS station, The Emporium, Benjakiti Park, Terminal 21, hospitals, office buildings, and several popular restaurants in the nearby neighborhood.
The building's interior is spacious and breezy, able to get a magnificent view of the city. The rooms in the project are designed with contemporary architecture. Thus, residents can create a variety of designs and give their own best. There are 2 and 3 bedroom styles with a spacious balcony and a large window to open for the morning sunshine. The floor is paved with the parquet. Furthermore, it offers a fully-equipped European kitchen.

We compute this from how much of this building's for-sale supply actually clears the market and how fast — tracking every listing from the day it appears to the day it disappears. A higher score means units here tend to find buyers; a low score warns that your exit could be slow. This is an availability signal, not a guarantee of sale price.
Retiree suitability
good place to retire?A retirement-focused read on the location: weighted toward nearby healthcare and clean air, then car-free transit and daily errands. Thailand's retirement (O-A/O-X) visa buyers weigh these very differently from young investors — this score reflects their priorities.

Air quality
5 months agoSource: WAQI station National Housing Authority Dindaeng, Bangkok, Thailand (การเคหะชุมชนดินแดง). AQI is a 0–500 composite scale (US EPA). Values above 100 are unhealthy for sensitive groups; above 150 for everyone.
Ground stability
is the land sinking?Outer ring, largely stabilised since groundwater pumping was regulated. District-level estimate from published InSAR and groundwater-monitoring studies — a relative long-term signal, not a per-building survey. Land subsidence amplifies the same areas' monsoon-flood risk over a 10–20 year horizon.

Frequently asked questions
Is Swasdi Mansion overpriced compared to the rest of Watthana?▾
Swasdi Mansion has a RealData Bubble Index of 61 — that is 39% below the median price-per-sqm of the Watthana district, which we classify as underpriced.
What is the monsoon flood risk at Swasdi Mansion?▾
Swasdi Mansion sits in a district with a RealData Flood Risk Level of 2/5 — occasional puddling. Risk is district-level, drawn from Bangkok Metropolitan Administration Drainage Department records, JICA reports, and the 2011 great-flood inundation map. Individual buildings may still flood ground-level parking even in lower-risk districts.
How is the air quality at Swasdi Mansion?▾
Latest WAQI air quality reading near Swasdi Mansion is 55 — Moderate. This is the index value from the closest World Air Quality Index station; PM2.5 levels in Bangkok swing seasonally and can spike during burn season (Feb–April).
Is Swasdi Mansion easy to resell?▾
Swasdi Mansion has a RealData Resale Liquidity Score of 28/100 — slow — your exit could take a while. 0% of the for-sale supply we tracked here cleared the market. We compute this by tracking every listing from the day it appears to the day it leaves the market, so it reflects how much supply actually clears and how fast — not just the asking price. It is an availability signal, not a guarantee of sale price.
Is the ground sinking at Swasdi Mansion?▾
Swasdi Mansion sits in a district with a RealData Ground Stability (land-subsidence) level of 2/5 — low (largely stabilised). Bangkok rests on soft marine clay and sank as fast as ~120mm/year in the 1980s from groundwater over-extraction; regulation has since cut inner-city rates to near zero, but the eastern belt and coastal south keep sinking. This is a district-level estimate from published InSAR and groundwater-monitoring studies, and it compounds the same areas' monsoon-flood risk over a 10–20 year horizon — not a per-building survey.
Is Swasdi Mansion a good place to retire?▾
Swasdi Mansion scores 79/100 on RealData's Retiree Suitability Score — an excellent fit for a retirement-visa buyer. There are 10 hospital/clinics within 1km, and the latest air quality reads 55 AQI. The score weights nearby healthcare and clean air most heavily, then car-free transit access and daily errands — the priorities that matter to retirees rather than young investors.
How does RealData verify the numbers on this page?▾
Every figure is computed from live listing data we re-crawl across hipflat, dotproperty, ddproperty, and fazwaz (daily for Bangkok, weekly for the full Thailand sweep). District medians come from the same dataset, the mortgage benchmark is Bank of Thailand BTWS_STAT, and flood / livability layers are pinned to government and OpenStreetMap sources. We accept no payment from developers and no building can buy its way up a ranking — advertising on this page is sold by a third-party network that never sees the data.
