Seascape
64 Sea Way, Middleton-on-Sea, West Sussex
Film by Fine & Country Chichester
Independent reading
An 11,184 sq ft waterfront residence with indoor pool, gym, sauna, cinema and self-contained annexe, set within Middleton-on-Sea's private coastal estate.
Seascape clears the Pavello benchmark through exceptional waterfront scale, resolved contemporary interiors, a complete private leisure programme and direct beach access. It is currently under offer. The £402/sq ft headline blends main accommodation, lower-ground leisure space, garage and annexe, so title, component measurement, planning, coastal exposure and plant condition are the decision-changing checks.

Identity confidence99%
Seascape, 64 Sea Way, Middleton-on-Sea, Bognor Regis
The live Savills instruction and current Rightmove distribution align on Seascape, 64 Sea Way, Middleton-on-Sea, PO22 7SA: a detached freehold waterfront residence at £4.5m with eight bedrooms, eight bathrooms and 11,184 sq ft. The Fine & Country film names the property and Middleton-on-Sea and matches the price, scale, coastal setting and leisure suite. The exact-address market record and HM Land Registry-derived history independently tie 64 Seascape to detached/freehold form, eight bedrooms and the £4.5m September 2022 transfer. The official title and UPRN remain buyer-side, but the named-house, number, postcode, accommodation, price, transaction and film alignment produce a decisive exact-property match.

- Savills currently records Seascape as under offer at a £4.5m guide: detached, freehold, eight bedrooms, eight bathrooms, three receptions and approximately 11,184 sq ft.
- The waterfront house provides an open-plan kitchen, formal reception rooms and a lower-ground indoor pool, gym, sauna and cinema.
- The principal suite has a balcony, dressing room and en suite, while a self-contained annexe above the garage adds two further bedrooms.
- The current instruction attributes mains water, electricity, gas and drainage, EPC D, Council Tax H and an approximately £200 annual private-estate charge.
- A publisher-controlled Fine & Country YouTube film names and shows the exact property; Aveno embeds the original privacy-enhanced player without copying, downloading, screenshotting or rehosting the footage.
- HM Land Registry-derived history records the exact detached freehold address transferring for £4.5m on 27 September 2022; that same nominal figure is an identity and transaction anchor, not proof of unchanged value.
