One of Mayfair's original Mansions, 21 Upper Grosvenor Street is an
attractive Grade II listed townhouse
constructed in 1732 and extensively
refurbished in 1908 by famed British
Architect Ralph Knott, well known
for his Edwardian Baroque style as
evidenced in his building of County
Hall in London. The re-fronting
of Upper Grosvenor Street was
described as 'extremely inventive'
in highly attractive Portland Stone.
Today the house has been restored
to its former glory, respectful of
its history but very much with
modern qualities.
With grand proportions throughout
including an 'l-shaped' drawing room
on the first floor leading to a large
terrace and a dining room on the
ground floor suitable for seating 20
guests, the house is ideally configured
for both formal entertaining and
comfortable family living.
The centrepiece of the house is the
family kitchen, unusually positioned
on the ground floor (supported
by a 'dirty kitchen' on the lower
ground floor), where families can
meet and congregate. As well as
the formal rooms, the main house
has a 5 principle bedroom suites
including the master bedroom which
occupies the entire second floor and
has its own private and secluded
roof terrace. Further bedrooms are
found in the generously proportioned
'Mews House' at the rear in Culross
Street which has its own drawing
room/kitchen as well as a wellappointed
gym and garaged parking for 2 cars.
The house has an enviable spa
with one of Mayfair's largest private
swimming pools, a gym/fitness
studio, separate spa pool, sauna and
for post work-out relaxation a private
screening room.
