Our latest lookbook features ten home interiors with snug sunken lounges and conversation pits, proving that the retro architectural feature is making its comeback.

Peaking in popularity in the mid-twentieth century, conversation pits are lounge areas embedded within the floor of a larger room to create intimate spaces for people to gather.

Accessed by a small set of steps, they are traditionally lined with custom built-in sofas. However, many architects enjoying their revival are opting to fill them with free-standing furniture and statement fireplaces instead.

While creating more intimate spaces for their occupants, sunken lounges are useful tools for creating broken-plan interiors and the illusion of taller ceilings. They can also prevent furniture from obstructing outward views, forging stronger connections between homes and their surroundings.

This is the latest in our series of lookbooks providing curated visual inspiration from Dezeen's image archive. For more inspiration see previous lookbooks showcasing glass-block walls, modernist open-plan living rooms and homes with interior courtyards.
