139 Piccadilly, Mayfair, W1J

Property Summary

139 Piccadilly is a Grade II listed building arranged over six floors, dating back to the mid-18th century. This grand, former townhouse offers over 14,000 sq ft of accommodation and showcases a smart period facade, beautifully preserved original features throughout, and far-reaching views over Green Park. It has most recently been used as an office building but is currently vacant from the ground floor up, with only the apartment at lower ground level occupied. This is an excellent opportunity for the regeneration of an impressive period building, and there is residential planning permission in place to convert the property back into a townhouse. There are four sizeable garages included within the sale, located on nearby Down Street Mews. We think this property would be suitable for individuals or families desiring a spacious and elegant home in a prestigious location with convenient access to Green Park and other amenities. Else, owners interested in restoring and converting historic buildings into several luxury apartments.

Development Potential

139 Piccadilly holds great residential potential, having received full planning permission on 26 August 2015 to convert it from an office to a single-family dwelling. This presents a rare chance to transform the property into an impressive townhouse measuring around 15,339 sq ft. The permission also allows for a partial basement excavation, a roof terrace, and a courtyard at the rear ground floor. It was implemented on 29 May 2018 alongside the listed building consent, exempting the development from Section 106 or CIL contributions and affordable housing provisions.

With generous floorplates of about 2,500 sq ft on each level and an existing lift, the property can be considered for subdivision into apartments, subject to obtaining suitable planning consent. This enables owners to maximize the property’s potential by creating multiple living spaces, enhancing versatility and investment value.
