A Legacy of Excellence in Property Management

From Humble Beginnings to Industry Leadership

Established in 2013 in Koh Samui, Siam Commercial Service (SCS) was founded by Mr. Quentin Vangramberen and his father, Jean-Jacques Vangramberen, with a clear vision: to provide reliable, high-quality property management and holiday rental services.

A significant turning point came in May 2015 when Mr. Loicq Provenier and Mrs. Sophie Limani took over operations, managing a modest portfolio of four properties—two condominiums and two villas. Through steadfast dedication and a commitment to service excellence, SCS quickly gained recognition as a trusted name in the industry.

Siam Commercial Service – Beyond Property Management. A Legacy of Trust, Growth, and Excellence.

What started as a modest endeavor with four properties has evolved into a full-service, industry-leading property management company built on the values of trust, transparency, and excellence.

At Siam Commercial Service, we are driven by a passion for hospitality, a commitment to quality, and a dedication to providing outstanding experiences. Whether you are a property owner, investor, or traveler, we are here to ensure your journey is seamless and exceptional.

Siam Commercial Service – Elevating Property Management in Koh Samui

At Siam Commercial Service, we specialize in providing comprehensive property management solutions for luxury villas and holiday rentals in Koh Samui. Our team of experts is dedicated to maximizing your property's potential while ensuring a seamless experience for both owners and guests.

At Siam Commercial Service (SCS), we take pride in being at the forefront of property management, luxury holiday rentals, and real estate services in Koh Samui. With over a decade of experience, we have built a reputation for professionalism, transparency, and personalized service, ensuring that both property owners and guests receive the highest level of care and expertise.

A changing market – The need for professional management

The Koh Samui villa rental market has experienced significant growth, with an increasing number of private villas being listed on platforms like Airbnb. However, many properties lack professional management, standardized services, and strategic positioning, leading to a reliance on visual appeal and price reductions to attract bookings. This has particularly affected inland hillside properties, where an oversupply has driven rates down. Meanwhile, beachfront villas remain in high demand due to limited inventory.

At SCS, we address these challenges by offering tailored, high-quality property management solutions that maximize returns while maintaining property value. Our expert team ensures properties are well-maintained, competitively positioned, and marketed effectively to attract the right clientele.

Our role in raising industry standards

As the market evolves, we remain committed to setting new benchmarks in property management by providing:<

  • Comprehensive Property Management – Full-service solutions, from maintenance and housekeeping to marketing and revenue optimization.<
  • Luxury Holiday Rentals – Exclusive, fully serviced villas that enhance guest experiences and drive premium occupancy.
  • Real Estate & Investment Services – Helping investors navigate the market with secure and professional property sales guidance.
  • Development & Renovation – Transforming properties into high-value assets through expert design and construction.

With a multilingual team fluent in French, English, and Thai, we ensure seamless communication and a stress-free experience for property owners and investors. Our commitment to excellence is reflected in our growing portfolio of premium properties and over 1,800 five-star guest reviews.

As Koh Samui’s property market shifts towards more professional management and high-quality hospitality, SCS continues to lead the way—enhancing property value, increasing occupancy rates, and delivering exceptional experiences for both owners and guests.
