Project Concept

The Base Sukhumvit 50 is shaped by a design concept that balances “urban convenience with a quieter soi atmosphere.” Located in Soi Roem Charoen, slightly set back from Sukhumvit Road, the project emphasizes privacy and everyday comfort. The massing and layout are planned to open up views, encourage cross-ventilation, and bring natural light into typical living hours, helping residents feel less boxed in despite a city setting.

The architectural language leans contemporary and minimal, with clean lines and easy-to-maintain finishes - practical for working professionals around On Nut and Phra Khanong, and also appealing for rental demand where a bright, functional room matters. Common areas are treated as mood-shifting spaces: corners for sitting, casual work, and green pockets that soften the transition from commuting to resting at home.

Connectivity is part of the concept as well, positioning the condominium as a “home base” for daily travel. BTS On Nut is approximately 1.3 km away, supporting a lifestyle that stays mobile without sacrificing the calmer, more residential feel of Sukhumvit 50. Overall, the design focuses on livability, clarity of space, and a relaxed city-home experience.

Project Highlights

The Base Sukhumvit 50 stands out for its practical location in Soi Roem Charoen, Sukhumvit 50, between Phra Khanong and On Nut. The neighborhood feels more residential and calm, yet it connects quickly to the Sukhumvit CBD, making it suitable for both end-users and rental-focused buyers.

  • Livable neighborhood Daily conveniences and local eateries around On Nut and Phra Khanong support an easy routine without relying on a car.
  • Transit connectivity Around 1.3 km to BTS On Nut and about 1.6 km to BTS Phra Khanong, giving flexible access toward Ekkamai-Thonglor or the Bang Na side.
  • Facilities that add value On-site common areas are designed for relaxation and fitness, improving everyday comfort and tenant appeal.
  • A balanced setting Close to the BTS while being tucked inside a quieter soi, offering more privacy than projects directly on the main road.
  • Investor angle Sukhumvit 50 typically benefits from steady rental demand from office workers and expats who prioritize BTS access and a calmer residential environment.

Description

The Base Sukhumvit 50 is located at 1198 Soi Roem Charoen, Phra Khanong, Khlong Toei, Bangkok 10110. This is a High Rise condominium in the On Nut area, around 1 kilometer from BTS On Nut Station, offering convenient access to Sukhumvit Road and the city center.

The project was developed by Sansiri Public Company Limited and completed in 2010. It consists of 1 residential building with 30 floors and approximately 415 units. Parking is available for around 60 percent of total units. Unit types include studio, 1-bedroom, and 2-bedroom layouts, suitable for both owner-occupiers and rental demand from working residents along the Sukhumvit corridor.

Facilities include a swimming pool, fitness center, garden, lobby, common sitting area, and passenger elevators. The security system features 24-hour security guards, CCTV, and key card access. In terms of management, the project is generally maintained under Sansiri's property management standard together with the juristic person, supporting long-term residential quality.

The location is close to Lotus's Sukhumvit 50, Century The Movie Plaza Onnut, Big C Extra On Nut, and the Chalerm Maha Nakhon Expressway. This makes the project attractive for both end-users and investors seeking rental demand in the On Nut neighborhood. For a nearby project, see Ivy Thonglor.

Price Trend

The Base Sukhumvit 50 in 2026 remains a practical buy-to-let option in the On Nut area, supported by steady demand from office workers and expats. The project is near BTS On Nut (approx. 700-900 m), offering convenient access to inner Sukhumvit.

  • Resale price per unit: 1-bedroom 30-34 sq.m. averages THB 3.2-3.9M
  • Price per sq.m.: about THB 105,000-125,000/sq.m. (floor, view, condition matter)
  • Average rent: THB 15,000-19,000/month for 1-bedroom; studio THB 12,000-14,500/month

Rental yield (quick math): buy a 32 sq.m. 1-bedroom at THB 3.45M and rent at THB 17,000/month. Annual rent = THB 204,000. Gross yield = 204,000 - 3,450,000 = 5.9% p.a. (before common fees, taxes, and vacancy).

Capital gain view: comparing typical 2023-2024 levels around THB 95,000-110,000/sq.m. to 2026 levels of THB 105,000-125,000/sq.m., upside is roughly 8-15% over 2-3 years. The key risk is rental competition from nearby projects such as Aspire Sukhumvit-Rama 4 and The Excel Hideaway Sukhumvit 50; units with full furnishing and realistic pricing tend to secure tenants faster.
