British real estate company SUSD has announced that it has gained planning consent to develop the Grotto Estate – a 3.5-hectare country retreat on the banks of the Thames river in Lower Basildon, UK.

Designed by Paul Forster, the future property, which will expand on a Georgian-era mansion said to have been designed by the renowned landscape architect Capability Brown, will feature 53 rooms and six two-bedroom detached lodges, two of which will be available for purchase.

Leisure and wellness facilities will include tennis courts and bars, as well as a restaurant, kitchen garden, boathouse, solarium, gym, swimming pool, and two-storey spa.

Speaking on the project, Harry Harris, founder of SUSD, said his team aims to "foster an experience relevant to the location and provide members with everything they need – from rooms, restaurant, bar, gym and spa, to cultural programmes, garden walks and riverside retreats".

He added: "We create destinations to match how people like to live their lives today, in the process revitalising buildings and sites that might not stack up as a standalone hotel or leisure venue."
