How to Set Up a Group Therapy Room: Space Design and Practical Considerations

Group therapy presents unique spatial challenges that one-to-one practice does not. The room must accommodate multiple people, facilitate visibility and connection, manage acoustics for multiple voices, and create a sense of psychological safety for every participant. Whether you are a facilitator looking to rent a group room or a provider considering whether your space is suitable, this guide covers the practical essentials of group therapy room design in the UK.

Space Requirements by Group Size

Group therapy is an established modality across the UK. The British Association for Counselling and Psychotherapy (BACP) and the UK Council for Psychotherapy (UKCP) both recognise group work as a core therapeutic approach, with specific training pathways for practitioners.

The space needed depends on the type of group and the activities planned. As a general principle, allocate at least three square metres per participant plus additional space for the facilitator to move.

• Small groups (4–6 participants): 20 to 25 square metres
• Medium groups (7–10 participants): 30 to 40 square metres
• Large groups (11–15 participants): 45 to 55 square metres

Groups larger than fifteen typically require a dedicated training room rather than a converted therapy space. For flexible consulting arrangements that accommodate varying group sizes, see our guide on how to design a hybrid consulting room.

Seating Configurations and Group Dynamics

The arrangement of furniture shapes the group dynamic as much as the facilitator does.

The Circle

A circle is the default configuration for most therapy and counselling groups. It encourages equality, maximises eye contact, and minimises hierarchy. For this to work, the room must be wide enough for a circle of chairs without squeezing participants against the walls.

The Horseshoe

A horseshoe arrangement works well for psychoeducational groups and training workshops where the facilitator needs a more central instructional role. It still allows group members to see each other while focusing attention on the facilitator.

Clusters and Breakout Space

For groups that include paired exercises or small-group discussions, having movable chairs and enough floor space to form subgroups is essential. Fixed furniture is a significant limitation for group work.

Acoustics and Confidentiality

Sound management is more critical in group therapy than in individual work because multiple voices create more sound energy, and conversations often become emotionally intense.

• Avoid rooms with partition walls or thin dividing screens
• Test whether voices carry into corridors or neighbouring rooms
• Use carpets, curtains, and soft furnishings to dampen echo
• Consider a white noise machine for additional sound masking

Accessibility and Inclusion

Group rooms must work for participants with varying physical needs.

• Step-free access to the room and nearby toilets
• Wide doorways for wheelchair users and mobility scooters
• Clear pathways between seating arrangements
• Chairs with arms for participants who need support standing up
• Adjustable lighting for those with visual impairments

Technology and Equipment

Modern group therapy increasingly incorporates multimedia and hybrid participation.

• Reliable high-speed WiFi for hybrid sessions or resource sharing
• A speaker or sound system for guided meditations and audio exercises
• Flip chart or whiteboard for psychoeducational content
• Extension leads and accessible charging points

Breakout and Quiet Space

Emotional intensity in groups sometimes means a participant needs to step out. Having a nearby quiet area, secondary small room, or corridor space where someone can compose themselves without leaving the building entirely is valuable.

Booking Practicalities for Group Rooms

Group rooms are typically hired in longer blocks than individual therapy rooms. When renting for group work, clarify:

• Whether the rate includes setup and clear-down time
• Whether you can store chairs, materials, or equipment between sessions
• What happens if the group overruns
• Whether the room can be rearranged and returned to its original state

Conclusion

A well-designed group therapy room supports the therapeutic process by creating physical conditions for connection, safety, and engagement. Focus on space, flexibility, acoustics, and accessibility, and your group will have the environment it needs to do meaningful work.
