Dover House, which recently completed construction, is made up of nine luxury apartments and retail space. The residential apartments sold for a total of £10.5m, while the retail scheme has been sold on a 999-year leasehold for £4.5m.
The unnamed investor bought the development "to add to [their] portfolio and benefit from rental income".
Fronting onto Westminster Bridge Road and Lower Marsh Street, the former hotel and restaurant - which was originally built for hotellier CHarles Best in 1894 - has undergone an extensive refurbishment project.
The Thackeray Estate oversaw the re-alignment of the property into seven apartments and two penthouses stretched across 16,000 sq. ft., with 7,000 sq. ft. of retail and leisure space.
The apartments and penthouses were interior designed by luxury interior specialists Argent Design. The retail space has been let to Co-Op, while the leisure space has been let to Anytime Fitness Gym.
