Info Overview

About the Omni One Plus.

The Omni One Plus is an architecturally refined, extended 1-person acoustic work booth engineered for professionals who need more space for deep focus, extended laptop work, and confidential video conferences. Building upon the compact footprint of the Omni One, the Plus edition delivers a roomier interior without compromising floorplate efficiency or requiring fixed cellular construction.


A Roomier Sanctuary for Extended Deep Work

While standard phone booths cater to quick calls, modern hybrid workflows often require longer periods of uninterrupted concentration. The Omni One Plus provides the ideal dedicated solo environment:

  • Enhanced Personal Space: An expanded interior footprint gives users generous elbow room and larger worksurface capacity for laptops, notebooks, and dual devices.
  • Certified Speech Privacy: High-performance acoustic layers isolate speech at the source, preventing sensitive client discussions from leaking and keeping open-office chatter out.
  • Architectural Glazed Openness: Expansive glass panels preserve natural daylight flow and visual connectivity across the office floorplate while maintaining full acoustic isolation.

Engineered for All-Day Comfort & Connectivity

The Omni One Plus seamlessly integrates premium environmental controls to support prolonged working sessions:

  • Whisper-Quiet Airflow: High-capacity, continuous ventilation exchanges air rapidly to keep the interior fresh and temperature-regulated during back-to-back calls.
  • Adjustable Task Lighting: Adaptable illumination allows users to dial in optimal lighting for high-definition video calls or softer ambient focus.
  • Complete Power Integration: Built-in mains power outlets, high-speed USB charging ports, and discreet cable management ensure seamless plug-and-play productivity.
  • Ergonomic Seating & Worksurface: Designed to accommodate comfortable task seating, sit-stand perches, or standing work configurations.

Designed to Belong in Modern Interiors

Constructed to blend harmoniously into contemporary workplace design rather than feeling like added industrial equipment:

  • Configurable Finishes: Tailor the exterior with precision powder-coated aluminium frames and choose from a curated range of high-performance acoustic interior fabrics.
  • Demountable & Freestanding: Fully modular and relocatable—easily repositioned across your floorplate or transferred to a new building as team demands shift.
  • Floorplate Optimization: Keeps larger conference rooms open for team collaboration by providing a superior destination for solo hybrid meetings.

Built for High-Performance Work Modes

  • Extended Video Conferencing: Acoustic clarity and flattering lighting for lengthy client calls on Zoom, Microsoft Teams, and Google Meet.
  • Intensive Analytical & Creative Work: A quiet haven for coding, financial modelling, document review, and strategic planning.
  • Confidential HR & Leadership Calls: Total speech containment for sensitive 1-on-1 consultations and executive discussions.
