The BASE Ratchada 19
Complex Characteristics
Residential Complex Description
The property is located in the Ratchada area, 750 m from Ratchadaphisek MRT station, and the project shuttle takes residents to the station. Sansiri has built three eight-storey blocks around a green courtyard, plus a separate clubhouse. The building was completed and registered in 2026, so the apartments can be viewed, transferred into your name and rented out straight away.
614 residential apartments on a plot of around 5 rai
1-bedroom apartments from 23 to 35 m², including a version with a multi-purpose room
286 parking spaces, including underground parking in the clubhouse building
a separate clubhouse: 25 m swimming pool, fitness centre, coworking space and a snooker room
apartments are handed over fully furnished, freehold
The clubhouse sits apart from the residential blocks to give residents more privacy. Inside are a Creative Hub with a meeting room, a Social Lounge with a bar, and a Playroom. One block is dedicated to cat and dog owners, with a Pet Playground next to it and a pet washing station.
Central Plaza Ladprao is 3.7 km away, and Lat Phrao MRT station, where you can change to the Yellow Line, is 2.1 km away. On the Blue Line it is six stops to Sukhumvit, with a change to Asok BTS.
The investment appeal rests on a finished building with no construction risk and on rental demand from the offices at Rama 9 and the universities in the district. The Thai Airways head office is 1.7 km away. Payment is split 30% on signing the contract and 70% on handover.

Developer
Sansiri is one of Thailand's largest and most established developers, whose projects can be confidently recommended to clients.
Sansiri Public Company Limited was founded in 1984 and has been among the country's leading developers for approximately 40 years. It is listed on the Thailand Stock Exchange (SET: SIRI), headquartered in Bangkok, and operates nationwide, developing condominiums, houses and townhouses.
Scale and figures
Founded: 1984.
Public status: SET listing since 1996.
Portfolio: hundreds of completed projects and tens of thousands of units; by the 2010s already 237 projects and over 60,000 properties across 9 provinces and one project in London.
2025: No. 1 in Thailand by number of new units launched — 1,847 units (approximately 12% of all launches in Bangkok and surrounding areas within the half-year period).
Plan for 2026: 30+ new projects with a combined value exceeding THB 50 billion, target sales of THB 48–53 billion, transfers of THB 39–46 billion.
Geography
Sansiri is particularly strong in:
Bangkok and its metropolitan area (urban condominiums and residential complexes).
Major tourist provinces (resort condominiums and complexes).
On Phuket, Sansiri is developing resort projects, one of which is RHEA by Sansiri in Cherng Talay, between Surin and Bang Tao beaches.
Developer approach and strengths
Sansiri positions itself as a full-service developer based on:
Property development — development of residential properties across different segments.
Property services — property management, brokerage, rental.
Hotel management and associated services.
Sansiri is one of few developers whose projects participate in official long-term investment and long-stay visa programmes for foreign buyers. Upon purchasing a condominium unit valued at THB 3 million and above and meeting immigration requirements, the owner gains the right to apply for an annual investor visa with renewal options, as well as to arrange residency status for family members.
In a number of pilot programmes launched on Phuket, Sansiri projects (including Rhea by Sansiri) are used as base properties for arranging such visas, and the developer, working with partners, assists owners with document preparation and submission.
Why we confidently recommend Sansiri to our clients
Nearly 40 years in the market and public status — transparent reporting, regular filings and investor oversight.
Strong track record — hundreds of completed projects, tens of thousands of handed-over units, leadership in number of launches and sales volume.
Experience in resort regions — not only Bangkok but major tourist destinations, including Phuket and projects such as RHEA by Sansiri.
Full range of services for owners — development, property management, rental and resident services, which is particularly important for foreign buyers.
Financial stability and growth plans — revenue exceeding $1.1 billion, profit around $170 million and dozens of new projects annually.
Through scale, experience and service quality, Sansiri logically belongs on the shortlist of developers that the agency can confidently recommend to clients considering property purchase in Thailand and Phuket.
