Design Concept

THE BASE Urban Rama 9 was designed around the concept of “Uniquely Your Urban Beat.”
The idea reflects the different rhythms, identities, and lifestyles found within Bangkok. Instead of creating one standard lifestyle environment, the development provides flexible spaces that residents can use for working, exercising, relaxing, socialising, or spending time privately.

The architecture and interiors combine modern urban design with expressive details, natural light, landscaped areas, and elevated facilities overlooking the Rama 9 skyline.

The common areas follow the complementary “Make a Statement” concept, using clean architectural forms, sculptural features, flexible furniture, and distinctive spaces to create a strong visual identity.
Statement Lobby

The Statement Lobby is designed as the project’s main arrival space.
Interior features include:

  • High, open ceilings
  • Large glazed surfaces
  • Abundant natural light
  • Sculptural chandelier
  • Flexible seating arrangements
  • Working and relaxation areas
  • Contemporary urban interior design

The multifunctional furniture allows residents to use the lobby for waiting, informal meetings, working, relaxing, or meeting guests.

The centrepiece is a sculptural chandelier designed to express movement, individuality, and the changing rhythm of urban life.

Residence Design

The residences are designed for practical city living, with layouts that use the available floor area efficiently.

Depending on the selected residence, interior features may include:

  • Separate bedroom and living areas
  • Private balcony
  • Large windows
  • Open-plan kitchen
  • Built-in kitchen furniture
  • Built-in wardrobes
  • Living and dining space
  • One or two bathrooms
  • High-ceiling configuration in selected residences
  • Fully furnished package
  • Air-conditioning
  • Space for a washing machine
  • Functional storage
  • City or surrounding neighbourhood views

Furniture, appliances, specifications, ceiling height, orientation, and included packages may vary depending on the selected residence and current sales promotion.

Exact specifications should therefore be confirmed using the latest unit inventory and sale documentation issued for the selected property.
