Adjacent Semi-Private Spaces

Summary

Create small, semi-enclosed collaboration areas next to team work zones. These spaces allow quick transitions between individual work and team discussions. Teams can collaborate without leaving their work context.

Context

Software teams need frequent, informal collaboration that builds on shared work context. Traditional meeting rooms create barriers and interrupt work flow. Completely open spaces lack privacy for focused team discussions.

Problem

Teams need a space for focused discussions that:

• Provides enough privacy for team conversations without complete isolation
• Maintains connection to the team’s work context and artifacts
• Allows team members to quickly join or leave the discussion
• Doesn’t require scheduling or booking procedures
• Supports both planned and spontaneous collaboration

Solution

Design small collaboration alcoves immediately adjacent to team work areas:

Physical Design:

• 4-6 person capacity for small team discussions (15-25 m² / 160-270 sq ft)
• 50-75% visual enclosure using low walls (1.2-1.6m height), movable panels, or book shelves
• Open entrance facing the team work area - no doors to create barriers
• Sight lines to team work space to maintain context and awareness
• Acoustic treatment to contain conversations without complete sound isolation

Detailed Acoustic Performance Specifications

Target Acoustic Metrics

• Speech Privacy: STI (Speech Transmission Index) 0.20-0.35 between adjacent spaces and team work area
• Sound Reduction: 10-15 dB attenuation for speech frequencies (125-4000 Hz)
• Reverberation Time: RT60 0.4-0.6 seconds within the semi-private area
• Background Noise: 40-45 dB ambient level to provide adequate masking
• Noise Intrusion: Maximum 50 dB from adjacent team conversations

Acoustic Material Specifications

Barrier Materials:

• Fabric-wrapped panels: NRC 0.75-0.95, 50-75mm thick
• Perforated wood screens: 20-30% perforation with acoustic backing (NRC 0.60-0.80)
• Flexible acoustic curtains: NRC 0.45-0.65 for adjustable privacy

Ceiling Treatment:

• Acoustic clouds: Suspended panels above seating area (2-3 m² coverage)
• Sound-absorbing tiles: NRC 0.70-0.85 in adjacent areas
• Partial ceiling: 60-80% coverage to maintain openness while controlling reverberation

Floor Treatment:

• Carpet tiles: NRC 0.25-0.35 to absorb footfall noise
• Area rugs: Define space boundaries while providing acoustic benefit
• Sound-absorbing underlayment: In hard-surface areas adjacent to collaboration zones

Spatial Relationship:

• Located within 3-5 steps of the team’s primary work area
• Part of the team’s “territory” rather than shared organizational space
• Visual and physical connection to team artifacts, whiteboards, and displays
• Positioned to not block natural light or circulation paths

Team Transition Protocols

Visual Signals for Space Availability

• Open Configuration: Furniture arranged in welcoming circle/U-shape
• In-Use Configuration: Chairs pulled close to table, whiteboard in active position
• Private Discussion: Acoustic panels positioned for maximum privacy
• Do Not Disturb: Specific furniture arrangement or simple signage system

Transition Guidelines for Teams

Joining an Ongoing Discussion:

• Wait for natural pause or eye contact acknowledgment
• Join peripherally before full participation
• Use visual cues (pointing, nodding) before speaking

Shifting from Individual to Collaborative Work:

• Team member initiates by moving toward adjacent space
• Others can join gradually rather than formal meeting start
• Maintain connection to individual work contexts

Returning to Individual Work:

• Natural conclusion signals: summarizing, action items, closing laptops
• Gradual departure rather than abrupt ending
• Preserve work artifacts for potential follow-up

Noise Management Protocols

Volume Guidelines:

• Conversational Level: Normal speaking voice (55-60 dB)
• Active Discussion: Slightly elevated but not conference-room volume
• Excited Collaboration: Brief periods acceptable, return to conversational level

Consideration Practices:

• Face inward toward collaboration area, away from individual workers
• Use whiteboards and gestures to reduce vocal volume needs
• Brief check-ins rather than extended debates in semi-private areas

Equipment and Tools:

• Small whiteboard or writable wall surface
• Pin-up space for sketches, user stories, or design artifacts
• Power and connectivity for devices
• Optional: small display for screen sharing or reference materials

Forces

• Privacy vs. Accessibility: Need for private conversation balanced with team integration
• Context vs. Distraction: Maintaining work context while minimizing noise impact
• Spontaneity vs. Structure: Supporting informal collaboration without scheduling overhead
• Individual vs. Team Space: Personal territory balanced with team collaboration needs
• Formality vs. Informality: Professional enough for clients but casual enough for daily use

Examples

Technology Companies:

• Spotify: Squad areas with adjacent “huddle corners” for quick team discussions
• Google: Semi-private collaboration nooks adjacent to team seating areas
• Microsoft: Team-owned collaboration spaces within engineering floors

Design Implementations:

• High-backed booth seating creating acoustic privacy while maintaining visual openness
• Movable acoustic panels that teams can adjust for different privacy levels
• Elevated platform areas that create defined space without walls
• Corner alcoves using building architecture to create natural boundaries

Consequences
