Ad man's folly

Explored some of the streets off the King's Road today and came across Glebe Place.
Number 50 was built in 1987 by Sir Frank Lowe, the name behind one or two major advertising agencies.

Even though I've worked in the area for long spells over the years, I'd never come across it until today. Nor heard anyone talk about it. Its aged patina certainly had me intrigued.
