Design Comment

The property’s expansive floorplate opens extraordinary possibilities for bespoke redesign. Subject to the necessary consents, the current layout could be reconfigured into a truly show-stopping residence with more than 2,000 sq ft of reception space overlooking the Square. The generous inner hall, already a focal point of the home, lends itself to statement design interventions—think art gallery walls or sculptural lighting. Meanwhile, the south-facing rooms could be transformed into a sunlit, contemporary living and entertaining hub. This is a rare canvas for a buyer with vision and appreciation for timeless luxury.

Development Consultations

To assist potential buyers of this property to understand their full design and development options, Janine Stone & Co. is able to provide complimentary design concept and development consultations. It can be arranged for these consultations to take place at the property or in our London studio. Janine Stone & Co. will provide guidance on architecture, refurbishment and planning considerations, in addition to helping interested parties to develop their early design ideas, into floor plans with estimated project costs and timelines for realisation.

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.
