12 Gloucester Square, Bayswater (NEW)

For Sale with Carter Jonas:
A London Family Home with Self-Contained Apartment

Tenure: Freehold
Guide Price: £6,950,000
Gross Internal Area: 5,357 SQ FT

Property Summary

Number 12 Gloucester Square is a well proportioned family home with access to one of London’s finest garden squares. The property features a roof terrace, a large patio garden and benefits from having access to a communal garden in one of the finest garden squares in London. The building includes a self-contained apartment, that would be suitable for household staff.  The location of the home places it within close proximity to Hyde Park and a multitude of premier amenities including art galleries, fine dining restaurants and schools.

Despite the property’s tired inward appearance, there is significant potential across five floors, and five thousand square feet, to transform this ugly duckling into a beautiful swan for its new owners.

Key Features

The current interior has a majestic quality, even if signs of tiredness are beginning to show. Some of the outstanding features have to be the grand, south-facing hallway, that acts as the home’s main entrance space, as well as a wood paneled drawing room with a trio of french windows opening on to a small terrace and overlooking private gardens.  A larger terrace accessed from the third floor provides an outside space to entertain guests in relative privacy. A rare luxury in prime central London.

Development Observations

Janine Stone & Co. has assessed the potential opportunities to bring 12 Gloucester Square into modern standing.

“The nature of this property gives any potential new owner lots of options for refurbishment and modernisation. It’s unlikely much structural work will be needed, but there are certainly a ways new owners would benefit from a job that re-purposes this home for modern life.

  • The number of bedrooms seems to be excessive.
  • By reducing the number bedrooms, the size of the master suite could increase.
  • Allowing for two en-suite bedrooms on the third floor, in additon to the other 2 en-suite bedrooms and master en-suite.
  • If the apartment was used as a staff residence, it would make sense to connect this space to a lower ground hallway.
  • By re-configuring the lower ground utility spaces, a garden room could be created with the current spiral stair case extending up to the first floor, where the existing bedroom could be re-imagined as a study – looking out on the world.

Development Consultations

To assist interested buyers of 12 Gloucester, Square understand their development options, Janine Stone & Co. has been asked by Carter Jonas to provide concept and development consultations. It can be arranged for these complimentary consultations to be take place at the property or in our London studio.

Should a successful acquisition take place, we would be happy to take these initial concepts, through to a full concept and subsequent planning, design and build phases.
