The firm said there were 5,200 new residences built within the area as a result of this market buoyancy – which has meant prime central London housing has outgrown inner London housing (Camden, Greenwich, Hammersmith and Fulham, Islington, Lambeth and Southwark) by 4%.

After developers took advantage of low land costs following the 2008 market crash, 144 development schemes have been completed in prime central London.

Pastor Real Estate head of sales and lettings Susan Cohen said: “We have found that not only are new homes getting bigger in prime central London, but everything that comes with them is getting grander.

“As wealth continues to pour into the capital, ultra-prime living standards increase.

“New buyers not only want larger homes providing more space for larger families, they also want all of the luxury amenities, concierge services, porters, five-star hotel quality spas and gyms, IMAX cinema rooms and private dining rooms to entertain guests at will.

“It’s noticeable that the websites promoting high-profile schemes such as Clarges, 20 Grosvenor Square and The Chilterns are now primarily promoting size, space and a full arsenal of luxury amenities.

“London is moving away from single units and, in years to come, we will see more and more fabulously luxurious, large lateral homes appearing on the market.”
