For our latest lookbook, we've gathered eight stylish closed staircases, ranging from a winding wooden spiral staircase to a light-filled "stairway to heaven".
Closed staircases – stairs that have been framed so that the threads and risers aren't visible from the side – have become a popular search term on Dezeen's Pinterest board.
While they create heavier volumes in a room, when done well closed staircases can add a monumental, almost sculptural feel to an interior.
In the eight examples below, architects and interior designers used the style in different creative ways to turn staircases into statement pieces made from materials including steel, patterned wood and micro cement.
This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration, see previous lookbooks featuring "bookshelf-wealth" interiors, living spaces with metal furniture and interiors punctuated by structural columns.
Barn at the Ahof, the Netherlands, by Julia van Beuningen
Architectural designer Julia van Beuningen created a spiral staircase made from plywood for this barn conversion in the Netherlands. The beautifully patterned staircase sits at the heart of the floorplan and contrasts against the barn's rough-hewn wooden beams and pillars.
"It's something you either love or hate, but it's definitely a statement," Van Beuningen told Dezeen.

Nithurst Farm, UK, by Adam Richards
Described as a "stairway to heaven", British architect Adam Richards created this staircase based on one in the film A Matter of Life and Death, in which a pilot gets a second chance at life after a crash.
It ends by facing a full-height window, creating a striking light effect that makes the staircase live up to its name.

Tommy Rand House, Denmark, by Tommy Rand
Perhaps the most monumental of the staircases in this roundup, the spiral staircase designed by architect Tommy Rand for his own house in Denmark was constructed from 630 pieces of CNC-cut plywood.
"It is very beautiful from all angles," said Rand. "It is like a snail house, which opens up more and more as you go up to the first floor."
