Open concept offices do not work for every business. Design quiet spaces designated for work with soundproofed cubicles and "quiet work area" signs. Have a separate area with tables, chairs, TV, etc. to break from work and chat with colleagues.
The open office craze does not work for every business and can be quite distracting with the low walls so you can see your neighbour, a group chatting nearby and people dropping by and interrupting you.
Design offices with designated workspaces that are distinctly quiet. Have higher walled cubicles with soundproofing, white noise in the drop ceiling and walls, office etiquette that accommodates quiet work and signs to mark the quiet space. If a quick meeting is needed, have drop in first come first serve mini-conference rooms, and bookable meeting rooms; again soundproofed.
When people need a break from work or need some interaction there is a designated open area with a tables, couches, chairs, pool table, TV, etc. In this space people are able to talk with colleagues and break away from work.
