Developer Leconfield has spent 18 months renovating the Chester Square property - where she lived from 1991 until she died in 2013 - so it now includes a lift, a newly constructed mews house to the rear and a private garage.
However it's not all new: the layout and design of the formal dining room and interlinking study on the ground floor is exactly as Thatcher had it during her 22 years at the property, while the entire first floor is given over to the drawing room and library, which said to be Thatcher's favourite room. It now features a pair of original Louis XVI fireplaces and parquet flooring, selected to match the house’s original floor.
The master suite uses the entire floor plate of the second floor, which comprises a large double bedroom, dressing area and master bathroom. There are a further five bedrooms in the property, including the option for staff accommodation.
George Brooksbank, managing director of Leconfield, said: “It has been a privilege to work on a property with such significant history. We have strived to achieve the perfect balance between traditional and contemporary living by respecting the house’s history and restoring many of the original features whilst tastefully incorporating the latest in modern technology. The quality of finish and attention to detail is in a class of its own and I’m proud of what we have achieved.”
Richard Gutteridge, head of Savills' Sloane Street office, added: “No 73 is certainly one of the finest houses on the Square, and the quality of renovation is outstanding. The property fully embraces its history and Grade II listed status, while the level of craftsmanship has enabled the careful creation of a modern yet traditional home that has cleverly reconfigured the journey through the house.
"Such an eminent and rare property, in terms of location, renovation and history, no 73 will have a truly widespread appeal to any buyer at this level of the market looking for an exceptional London home. If only the walls could talk.”
