The Howard de Walden Estate is owned directly and indirectly by a number of members of the Howard de Walden Family. The Estate owns, manages and leases the majority of the 92 acres of real estate within Marylebone, which comprises the area from Marylebone High Street in the west to Robert Adam's Portland Place in the east and from Wigmore Street in the south to Marylebone Road in the north.

The area has some of the most beautiful Georgian architecture in London. Our port- folio of properties to let includes not only offices and residential accommodation, but also retail units on and around Marylebone High Street and medical units centred on Harley Street.
