This staircase begins by drawing the inner radius on the floor.
The new addition, which was octagon,
created somewhat of a challenge
in the fact that the outer diameter
lay against it.
A CAD drawing was created to help guide
The transition from radius to octagon.
Next forming the railings and setting the posts.
The project also involved double doors
below the balcony, which had to follow
the radius of the wall.
The treads and upper edgings were created using templates.
