Harry Redknapp and his wife Sandra have put their former Sandbanks waterfront estate back on the market for £12.5 million, almost twice the £6.8 million they sold it for in 2019.. The property,known as the Solaris, was bought by the Redknapps for about £4 million in 2015 and has since been extensively remodelled into a high‑tech smart home.

Renovation upgrades push price to £12.5 million

The Solaris now features full app‑based control of lighting, climate and security, a massive aquarium wall in the hallway, a basement wellness suite and a state‑of‑the‑art cinema room , according to the listing. These upgrades are cited as the main drivers behind the asking price, which dwarfs the £6.8 million resale figure recorded five years ago.

Redknapp’s 2015 purchase and 2019 profit margin

Public records show the Redknapps acquired the Poole property for an estimated £4 million in 2015. Five years later they sold it for £6.8 million, netting a profit of roughly £2.8 million, as reported by the source.

UK house price growth versus luxury market spikes

Since the Redknapps’ 2019 sale,average UK house prices have risen just over 10 percent, yet the Solaris now commands a price increase of nearly 84 percent. This disparity highlights how ultra‑luxury waterfront homes can outpace broader market trends when extesive tech‑focused renovations are added.

Who might buy a £12.5 million smart‑home?

Potential buyers are likely high‑net‑worth individuals seeking a turn‑key, technology‑rich retreat on the coveted Sandbanks peninsula. The listing does not disclose any interested parties, and the market for such niche properties remains relatively thin.

What remains unclear about the sale?

The source does not reveal whether the Redknapps are still involved in the sale process or if any agents have secured offers. Additionally, the exact cost of the recent renovations has not been disclosed, leaving the true return on investment open to speculation.
