A unique freehold 'key-house' located in Knightsbridge. This development opportunity has planning permission for a magnificent residence with a linked mews house.



Description

The existing property is currently laid out as three separate apartments plus a mews house at the rear. The property is the principal 'key-house' on the most sought after east side and is the only property with direct views through to Sloane Street.

Planning permissions has been obtained from Westminster Council to create a grand single residence with integrated mews house, 10 bedroom suites, impressive entertaining rooms, large passenger lift with step free access throughout the property, three outdoor terraces, swimming pool and spa complex and internal parking for two cars and additional private parking in the mews.

An unusual and important aspect of this property is that it is not listed and not within a conservation area. Nor is it part of any estate management scheme.
