A new patio area leading from a new extension to the back of this
beautiful old Welsh farmhouse is laid with rectangular flagstones and
diagonal ‘channels’ of blue Welsh slate. A steep bank rises and is
designed as a series of wide amphitheatre steps providing drama and
impact, the distance between the steps based on the Fibonacci number
sequence. The 1st terrace is planted; the 2nd is turfed and can be
walked on; the 3rd has slate fishtail tiles set into cement at an angle
of 30 degrees.
