Writes Andrew Sorene from Central London estate agents Frank Harris and Company:

“Tonight I am going out for drinks after work at the splendid gothic Rennaissance Marriott Hotel at St Pancras International with an American couple to whom I sold them a flat 21 years ago – guess you could call it an overdue celebratory drink!

“I did in fact sell their flat for them in April 2000 when they gave up their London home. They truly cannot believe the huge increase in values in the area nor get over how much effect the King’s Cross redevelopment is having.

“Interestingly enough we currently have a one bed flat in the building in which they used to live, on the market at £385,000. Click here for more details.”
