Each apartment at 50 Hallam Street has large open-plan living areas This attractive, 1930s Art Deco building previously housed the Royal Society of Paediatricians - a major institution in the Marylebone area.

Before this, 50 Hallam Street was part of the General Medical Council's offices - it received Grade II designation in 1954. Hallam Street is situated within the boundaries of the ancient Manor of St Marylebone.

The history of the Manor can be traced back to the Domesday Book in the 11th century, when the area was divided into two manors, Lilestone and Tyburn.
The development has just been launched. It has three duplex lateral apartments including a penthouse. 50 Hallam Street shows Marylebone has come of age and is now undisputedly one of London's most exclusive and cultured neighbourhoods. Property prices in the area have recently started to match Knightsbridge and Mayfair. But Marylebone is more ‘Boho-Chic' than smart with its independent boutiques, food shops, organic cafes, garden squares, farmers market, high-end restaurants and fashion outlets.
The area is steeped in history and culture too - the Royal Academy, the Wallace Collection, and Wigmore Hall. West End theatres are all within walking distance. In addition, the new development is only a few minute's walk from Oxford Street, Regents Park, Marylebone High Street and the West End. Oxford Street, Baker Street, Great Portland Street and Regent's Park underground stations are all close by.
The properties at 50 Hallam Street boast Art Deco marble, oak/walnut flooring and listed ceilings in certain areas. Every property has his and hers showers and private dressing areas. Each apartment is different - not one is the same. However, a recurring theme in each property is very large, open plan living spaces.
All the apartments are equipped with the most up-to-date technology, particularly with regard to security. Home automation systems are interfaced through Apple iPads that allow complete control of Blu-ray, TVs, music library and home automation devices such as lighting, curtains and blinds. All the apartments have one or more garden terraces - a rarity in this part of London. And all three properties have open gas fire places.
The Regent apartment on the first floor has a regal feel with 5.9m high ceilings in its drawing room. Natural light in the room is superb with 5.4m, almost floor to ceiling windows, on both the east and west side of the room.
A spiral staircase leads up to the kitchen, which has a window overlooking the drawing room. A large terrace is accessed via the kitchen. Striking deco marble flooring in the entrance lobby adds to the sophisticated feel. Interestingly, a ‘pod' shower is placed in the middle of the first floor bathroom due to the building's listed status, which does not permit anything being built against the walls.
The penthouse has four bedrooms on the third floor and an open plan living space upstairs on the fourth floor. It is lofted space that lets light in via a large skylight. The apartment also has two large terraces and huge dressing rooms and wardrobes. A study is located within the open plan dining and kitchen area but it has doors that enable an owner to close it off if needed. Prices range from £5.5 to £7.5 million. (Approximately Dh27.5 to Dh37.5 million.)
