The Castle sells at Avalon

The keys and crown of Jonathan and Amanda Erwin are set to be handed over following the sale of their sandstone castle at Avalon for $2,542,500.

Set up 100 steps at 40 Chisholm Avenue, it finally achieved its $2.5 million plus expectations, but took more than a year to do so through LJ Hooker Palm Beach selling agent David Edwards.

Set on the northern side of an unspoilt rocky summit above Clareville Beach, it was the opera devotee architect Edwin Kingsberry's idea to build the house, however he lacked the funds and the land sold to Leslie Erwin, a salesman for Colgate/Parmolive.

Erwin constructed it as a present for his wife. However, his wife - and the mother of the current vendors - ran off with the architect.

Inspired by the music of Wagner, the palatial medieval property got its official name — Götterdämmerung — from the composer’s famous Ring Cycle opera, but locals just call it The Castle.

Music still resounds from the home, with Jonathan, an antique furniture restorer, a member of the northern beaches band, Bilgola Bop Band.

At 3238 sq metres, this block of land is one of the largest on the peninsula, with the privacy of the site never to be threatened.
