Read the full agent description
Hook Park is a very prestigious location close to Warsash with access to the Hook with Warsash Nature Reserve which combines, woodland, pasture and wetlands to provide a habitat for a diverse range of wildlife and includes the shoreline of Southampton Water up to the mouth of the River Hamble well known as a yachting Mecca for yachtsmen with several marinas within a few minutes drive. Warsash has a wide range of local amenities including several pubs, shops, a cafe, an active Tennis Club within walking distance and several golf clubs a short drive away. There are numerous footpaths and one that leads to the village of Warsash along the foreshore where the iconic "Pink Ferry" will take you across the river to Hamble village. Solent Way, a well known walking route, is within a few minutes walk and is very popular for dog walking. Access to the M27 at J9, airports in Southampton and Bournemouth and mainline trains from Fareham and Southampton Airport Parkway give easy access to all parts of the UK and areas of Europe.
On leaving Newtown Road in Warsash you will drive over a bridge into Hook Park which is worlds away from the mainstream and an oasis of calm. The original mansion, Hook House, built by William Hornby in 1790 was modelled on Government House in Bombay, where he was the Governor, on land given to him on his retirement by the British Government. Over the ensuing years the house was neglected by his descendants but early in the 20th century a new owner started a renovation project but it is likely that a fire was accidentally started by contractors working on the house and it was totally destroyed and never rebuilt so the land was sold for development.
Located on a large plot of 1.3 acres Cotswold House is a substantial family home with an attractive facade to the front that is approached over a sweeping gravel driveway which leads to the front entrance, two double length garages with space for 8 cars, a single garage attached to the Pool House and ample parking for several cars. There are steps up to an imposing front door which leads into a large reception hall.
The accommodation in the house extends to 4200 sq ft and is spread over 2 floors which includes on the ground floor a drawing room with substantial stone open fireplace and oak beams, original polished wood flooring, double aspect dining room, family room and a kitchen with separate breakfast/casual dining area. On this floor there is also a guest bedroom with ensuite bathroom and separate rain shower. There is also a cloakroom and utility room.. Stairs lead to the first floor landing with access to a large balcony overlooking the nature reserve and Southampton Water. A principal bedroom with ensuite bathroom and 3 further bedrooms, a family bathroom and a small nursery are all on this floor.
Outside there is a single story building of 543 sq ft currently used as a one bedroom home called The Pool House which could easily be converted ( subject to planning regulations) to create a gym, sauna, spa, showers and changing rooms for the pool(currently unused) that is located to the front of this building. Adjoining the main house there is a double length garage with a 2 bedroom flat that has a kitchen/living area above and a separate entrance to the rear. Between the house and garage is an internal yard currently used as a dog run and kennel. There is a gardener's WC there too. The second double length garage is detached with a one bedroom Garden Flat above. Both these buildings lend themselves to re-development as a home office or incorporation into the main house to create more space.
Currently, each unit is let under the terms of the Renters Rights Act which became law on May 1st 2026 and are generating approximately £1000.00 per month each, inclusive of heat, light and Council Tax. The Pool House is separately rated at Band C. The two flats are included in the main house for Council Tax purposes.
Agent's Note:
- The Pool House and one of the flats has been separately assessed for energy efficiency, the other flat is included in the assessment of the main house.
- AI has been used to demonstrate what the pool could look like when filled with water.
