Description

This three-bedroom apartment located on the second floor of a desirable 1930s building in Portman Square presents an excellent opportunity for someone looking to renovate and invest. Positioned quietly at the rear of the property, it is currently unmodernised and requires significant refurbishment to bring it up to contemporary living standards. The apartment benefits from 24-hour security services and residents can enjoy exclusive access to the private gardens of Portman Square, complete with a tennis court. Additionally, the lease has just 7 years remaining, but the new owner can apply for an extension that will add another 90 years. The vibrant surroundings include high-end shopping at Selfridges, Oxford Street, and proximity to Hyde Park, making this an attractive investment for anyone willing to undertake a renovation project.
