Homeward-bound for £45m Mayfair Mansions

One of the biggest resi deals of 2014 has just gone down in Mayfair. We hear this £45m stonker on the corner of Balfour Place and Mount Street has been snapped up for an undisclosed sum.

Following an inspired conversion at the hands of two of London's top architects, the Barbican Estate's former Estate Office has come up for sale sporting a £4.5m price tag.

We may be nearing full festive mode, but it sounds like a couple of significant deals have gone/are going down in Mayfair.
