About this property

Forming part of an historic Grade II* listed castle, with 16th century origins, this distinguished four‑bedroom duplex penthouse added in the early 2000s presents an exceptionally rare opportunity to acquire a residence of significant character and outstanding coastal outlook.

The property benefits from four private terraces, two capturing uninterrupted views across Southampton Water toward The New Forest and Southampton Docks.
The apartment is sold with a share of the freehold, granting access to approximately three acres of landscaped communal gardens, direct access to the shoreline, and the use of the castle’s Victorian Great Hall.
The estate is approached via electric security gates, leading to a sweeping driveway passing the castle’s principal elevation and continuing to the garaging facilities.
The accommodation extends to approximately 2,700 sq. ft. across two floors, complemented by an additional 950 sq. ft. of external terrace space. The interior has been arranged to offer modern, spacious living while respecting the building’s historic form. A notable architectural feature is the octagonal turret, comprising a bedroom suite on each level, connected by a spiral staircase and incorporating an upper mezzanine.
The main reception rooms include a large drawing room and an adjoining dining room, both well‑proportioned and arranged to take full advantage of the setting. The upper floor features a central sun room providing access to the substantial rooftop terrace, which enjoys panoramic views. Of the three additional terraces, one adjoins the dining room with a waterside outlook, while the remaining two overlook the gardens and woodland to the front, offering cooler morning sun.
Each floor benefits from it's own entrance, and with a utility room on the upper floor there is scope for it to be used as an independent annex, or for long term rental purposes.

Outside
The site originally formed the gatehouse to the neighbouring Cistercian Netley Abbey, and subsequently became the foundation for a coastal fortification. The castle later played a strategic role during the English Civil War in 1642, when it was utilised to assist in the blockade of Southampton Water. During the 20th Century the castle was used as a convalescent home before being converted into ten private residences.

Situation
Netley Castle occupies a prime waterfront position on Southampton Water, opposite the historic Abbey ruins and a short walk from Netley village centre. The village offers local sailing clubs, the expansive Royal Victoria Country Park, and nearby infant and junior schools, with a secondary school in Hamble. Old Netley railway station provides links to Southampton and Portsmouth, while the M27 is easily accessible. Southampton city centre lies approximately four miles away.
