Secret Dorset: How shifting spit of land became millionaire's row

In Sandbanks, Poole, a single undeveloped parcel tied to a German banking family still remains about a century after its early expansion. Dr. Edward Andreae rented a cottage there in 1919, then began buying plots and building homes for his eight children—an approach Waters says “played a bit of Monopoly” with Sandbanks. Today, most Andreae properties have been sold and redeveloped, but roughly one acre of Andreae land appears to be the last unbuilt section. Waters estimates the site—described as including a staff cottage, tennis court and frontage beach house—could be worth up to £20m. It’s held in a family trust.
