Within the main accommodation area daylight was admitted via a double-glazed and shuttered window and through a small square pane high on the northern wall.

Side elevations were generally plain, with shuttered windows or doors.

Shuttered windows are built into walls incised with profuse painted floral carvings.

The pithead was made airtight against its reduced internal pressure by shuttered windows and close-fitting doors.

There are shuttered windows on either side of this door.
