As decks are evolving so are the designing of stairs. Spiral staircases have become more popular in the last few years. The increase of decks using a Spiral Staircase are due to a few reasons. The first being that most homeowners are now using maintenance free deck products instead of traditional wood. In previous years spiral staircases have always been more expensive than traditional wood products. Now homeowners are finding that a Spiral Staircase can actually save them money when compared to a traditional staircase with maintenance free deck material.
The second factor of the increase is that homeowners are now more concerned about staircases taking about valuable yard space. A spiral staircase is very efficient in overall space. Also a spiral is easier on the eyes with a great architectural look. If you are considering a new deck or re-doing an existing one a spiral staircase might be they way to go.
