The Base Wongsawang
About the project The Base Wongsawang
The Base Wongsawang is a single forty-storey tower on three rai beside Wong Sawang Road in Bang Sue. Six hundred and eighty-four apartments on three rai is central-Bangkok density, and one thing justifies it: Wong Sawang MRT station is a minute's walk away.
The mix starts at 25.25 sq m and ends with two-bedroom units of 46; in between are one-bedrooms of 29–30 and a type with an extra room at 34.5. A separate line is the Loft: the same 29–34.75 metres but with double-height ceilings. Parking is 41% — fewer than half the apartments, and for a buyer that is the first question to ask of this building: a space of your own cannot be assumed.
The shared spaces sit on two levels: below, a lobby with a semi-outdoor section and a dog park; above, a 35-metre pool, the fifth-floor garden, a gym with a free-weights zone, a co-working space with two meeting rooms, and a sky lounge under the roof.
The legal section below names the developing legal entity: Woraphinit, not Sansiri itself. The arrangement is ordinary for Bangkok projects, but the obligations sit with the company named in the document.

Can a foreigner own an apartment in The Base Wongsawang?
Yes, within the foreign quota: under the Condominium Act B.E. 2522 foreigners may hold up to 49% of a building's total saleable floor area, and the Land Office checks the ratio at the moment of transfer. How much of the quota The Base Wongsawang has left is not published anywhere — ask the building's juristic person for a certificate before the deposit and again before the transfer.
Can The Base Wongsawang be bought on a leasehold?
Beyond the 49% foreign quota apartments in Thailand are sold on a leasehold — a lease right of up to 30 years registered at the Land Office. Renewal is a clause in the contract, not a guarantee given by the law, and it is registered anew each time. Whether a leasehold is available in The Base Wongsawang right now, and on what terms, is a question for the developer.
Do I have to come to Thailand for the deal?
Not necessarily: the transfer can be done by a representative under a power of attorney certified at a Thai consulate. Money for a foreign-quota purchase must arrive in Thailand in foreign currency through a Thai bank — the bank's certificate of that transfer is required at the Land Office (Condominium Act, section 19).
What is paid on top of the price of an apartment?
The transfer is paid for at the Land Office, and the building charges a common area fee monthly and a one-off sinking fund payment. The rates for The Base Wongsawang are on this page where the developer publishes them; taxes and the transfer fee depend on the seller and on how long the unit has been owned.
