Super-sized Kensington penthouse hits the market at £12.95m

When properties come up on London's Carlton House Terrace, it's generally seen as a pretty big deal.

One of the most impressive new-build country mansions we've seen in a while has just come on at a shade under £20m.

With the 144th Open Championship swinging into action at St Andrews today, Savills has picked a cracking time to launch this apartment with grandstand views of the 18th.
