“Looking for a party room that is both ‘quiet’ and ‘wowed’ at the same time… Is it really possible?”
When talking about a reception room or private lounge, what space owners want is not just aesthetics, but the “atmosphere” that makes every gathering more special than usual.
Both lighting, sound, and the feel of the space must work together. This is the starting point of the project SKV13 – Private Lounge on Sukhumvit 13

| Project Information
Project Name: SKV13
Location: Sukhumvit 13
Solution: Trandar Seamless Acoustics, Altarfire Series (Smooth Surface) |
The Brief: A Party Room Where “Sound Must Be Good” and “Atmosphere Must Be Right”
This space was designed as a host's reception room for socializing and parties, with two main requirements that had to be met simultaneously:- An outstanding atmosphere that creates an experience
- Good sound quality without echo, not disturbing the usage
Because in a room of this nature, without proper sound control, conversations and music will echo back and forth, making the atmosphere “stuffy” and “uncomfortable to listen to.”

The Challenge: When the “Ceiling” Must Do More Than Ever Before
What makes this project special is that the ceiling does not just absorb sound, but must be a “main design element” with key challenges:Namely:
- Must be paintable to control the tone of the space
- Must be able to install a large number of “lights” to create a “starry sky” effect
- And these lights are relatively heavy, which ordinary acoustic ceilings cannot easily support
This is therefore a challenge that requires acoustic understanding + structural systems + design work
Solution: Seamless Supporting Both “Light” and “Sound”
Trandar introduced Seamless Acoustics, Altarfire Series (Smooth Surface) so that the ceiling can perform all functions completely.
Key highlights of the system in this project:- Seamless Surface
Enables the ceiling to form a continuous, single surface, ideal for creating a "night sky" effect without distracting visual joints.
- Supports Custom Painting and Design
The surface can be painted as desired, adding depth to the room's design and clearly establishing the spatial mood.
- Special Installation-Compatible Structure
The system is engineered to accommodate specialized lighting fixtures with specific weights and positions, bringing the “starry sky design” to life within the space.
- Acoustic Performance
Despite additional design and installation work, the ceiling continues to absorb internal sound reflections, reducing echo and creating a natural conversational atmosphere.
Result: A Space That Is Both “Wowsome” and Comfortable
Upon project completion, this Private Lounge has transformed into a space that:- Offers a view of a “star-filled sky” when looking up
- Features a warm, memorable atmosphere
- Provides excellent sound control across all activities
Because ultimately, a great space shouldn't just “look beautiful”—it must “feel right” every time it is used.
