Photos above show a four poster staircase for attic access. It runs at 43° and is fully recycled.

Construction of staircases with correct ergonomic application is critical. No matter your height, everyone lifts their feet comfortably to the same level. Excellent results are achieved by employing ergonomics in tread depth, rise and going. These are all critical factors in the construction of a staircase.

The same factors also apply to head clearance which is often overlooked in construction. Rise height needs only to be 10mm higher than ergonomically correct. This would make the staircase tiring to ascend. The ergonomics also apply to the tread depth. If the tread depth is too narrow, this will leave your heel hanging over the front edge, likewise to descend will force you to twist your foot at an inverted angle to prevent your toe from protruding over the front edge of the tread.

Continuous curved and laminated balustrades are easier to use as the need to lift hands over posts is eliminated. The use of a variety of timbers needs to be determined as to the position of the staircase. If it is to be fully exposed inside a building, it needs to be finished as a piece of furniture would be.

Mezzanines create dramatic visual lines and open up an overhead area. The topographical view experienced from a mezzanine area is always interesting and creates ambiance in an otherwise high walled visual aspect. Bridge style walk ways can be accommodated within a mezzanine area creating links between floors.
