Once the channel and glass were installed we clad the exterior in more Dinesen Douglas Fir for a seamless look. We've also hidden an LED strip to downlight the threshold of the stairs.
I eventually found the time to lye and oil the Dinesen Douglas staircase (see What a beautiful floor). The lye lightens the floor and prevents the orange colour developing.
As a handrail is a Building Control requirement I quickly had to come up with a design.
