The Base Urban Rama 9

The Base Urban Rama 9 – A Sansiri Condo in the Heart of Bangkok's New CBD

The Base Urban Rama 9 is a high-rise condominium developed by Sansiri, one of Thailand's most established SET-listed property developers with over 33 years of experience. Located in Huai Khwang district, on Rama 9 Road, this 29-story residential tower brings together a low-density design, premium shared facilities, and one of Bangkok's most connected locations — making it a compelling choice for both owner-occupiers and investors looking for a Bangkok condo for sale in 2025–2026.

Project Overview: The Base Sansiri Rama 9

The Base Urban Rama 9 is part of Sansiri's well-regarded The Base condominium brand, a series of urban mid-to-high-rise projects designed for city dwellers who value both lifestyle and connectivity. This specific project comprises 311 freehold units spread across 29 floors, with a single-corridor hallway layout that limits the number of neighbours per floor — a deliberate design choice that prioritises privacy and quiet living.

Unit types range from compact studios of approximately 28 sq.m. to larger two-bedroom layouts reaching 58 sq.m., including distinctive Loft-style units with double-height ceilings that are particularly sought after by expats and design-conscious buyers. All units are delivered fully furnished, ready for immediate move-in or rental.

Starting price: ฿3.59 million (approximately USD 98,000), with a management fee of ฿79 per sq.m. per month.

Location: Rama 9 Bangkok's Emerging Business District

Few areas of Bangkok have attracted as much infrastructure investment as the Rama 9 corridor. Often referred to as Bangkok's New CBD, the neighbourhood is home to major corporate headquarters, international hospitals, and a growing retail ecosystem — all concentrated around the intersection of Rama 9 and Ratchadaphisek roads.

The Base Urban Rama 9 sits at one of the most strategic points in this zone:

• 300 m to MRT Rama 9 (Blue Line, BL20) — one of Bangkok's busiest interchange stations
• Upcoming MRT Orange Line station nearby, set to dramatically expand east–west connectivity across the city
• 900 m to Central Rama 9, one of Bangkok's largest shopping and entertainment complexes
• 600 m to Praram 9 Hospital, a major private medical facility serving expatriates and international patients
• 750 m to G Tower, a Grade A office building housing multinational companies
• Direct access to the Si Rat Expressway (1.1 km), making car travel across Bangkok significantly faster

This combination of Blue Line access, imminent Orange Line proximity, and Expressway links makes the location particularly appealing for international residents working across multiple business districts.

Amenities: Urban Living at Every Level

Sansiri designed The Base Urban Rama 9 around the concept of "Uniquely Your Urban Beat" — the idea that residents should be able to live on their own rhythm without compromise. The amenity programme reflects this with a vertical stack of purpose-built spaces:

The Cloud (Floor 27) — a half-Olympic swimming pool with panoramic city views, designed as the project's social centrepiece.

The Work & Life Hub (Floor 28) — a co-working zone and meeting area catering to remote workers and entrepreneurs who need professional workspace without leaving home.

Sky Court (Floor 29) — a rooftop garden with 360-degree views of the Bangkok skyline, perfect for unwinding after work.

Sky Lawn — a sky garden with 270-degree city views, positioned as a genuine green retreat above the urban noise.

The Work Out — a fully equipped fitness centre including yoga and Pilates rooms.

Hidden Triangle Garden — a private garden on the ground level offering calm and natural light away from the street.

Statement Lobby — a double-height entrance lobby that sets the tone for the building's quality of finish.

Parking covers approximately 54% of total units — notably higher than Bangkok's urban condominium average — and EV charging points are available, reflecting Sansiri's Sustainable Design commitment.

Sansiri: A Developer with Decades of Track Record

Buyers purchasing a Sansiri condo benefit from one of the country's longest-standing developer reputations. Sansiri has been listed on the Stock Exchange of Thailand (SET) for decades and has delivered hundreds of residential projects across Bangkok, Phuket, Chiang Mai, and internationally. The company operates its own property management arm, Plus Property, which handles post-handover services — a significant reassurance for foreign buyers purchasing remotely.

The Base Urban Rama 9 was notably built and completed before being opened for public viewings, allowing buyers to inspect the actual unit, actual views, and actual common areas before committing — a practice Sansiri explicitly promotes for this project.

Buying as a Foreigner: Bangkok Condo Ownership Rules

Foreign nationals can legally purchase condominium units in Thailand under the 49% foreign freehold quota rule. At The Base Urban Rama 9, foreign buyers can hold full freehold title to their unit, with no land ownership required. This makes The Base Urban Rama 9 a straightforward and legally accessible option for expats and overseas investors looking for a Bangkok condo to buy.

Transfer fees and taxes are standard across Thailand: the developer typically covers transfer fees during promotional periods, so it is advisable to confirm the current terms directly with the Sansiri sales team.

Investment Potential: Why Rama 9 Bangkok in 2026

The Rama 9 New CBD is one of the most actively developing zones in Bangkok for real estate investment. The area already hosts Grade A office supply from major Thai corporates and multinationals, sustaining consistent rental demand from executives and young professionals. Historically, The Base brand projects in the Rama 9 corridor have shown stable secondary market values, driven by ongoing infrastructure upgrades.

The pending completion of the MRT Orange Line — which will add a new direct connection through the heart of Bangkok — is expected to further increase the area's accessibility and, by extension, rental appeal. For investors targeting Bangkok condos with long-term rental yield potential, the combination of Sansiri's brand, the New CBD location, and the incoming mass transit expansion makes The Base Urban Rama 9 a project worth serious consideration.
