Behind the main hall and with a lowered ceiling, the back seating area is a rectangular box-shaped space all covered in oak, from ceiling to floor, like a timber niche inserted inside the main hall.

The first floor timber box can then appear to sit lightly on top.

British architect Adam Knibb has added this cross-laminated timber extension to a house in the English county of Hampshire, and connected it to the former barn building by a frameless glass box.
