According to Wallpaper.com, the four-storey Carroll Gardens townhouse, purchased in 2021 for $3.35 million (AUD $5.1 million), underwent an extensive renovation led by renowned designer Billy Cotton and architect Ben Bischoff of MADE.
The property now boasts a blend of traditional English charm and bold maximalist design elements.
According to Zillow, the 22-foot-wide brownstone features a living room adorned with intricate Zuber wallpaper and a grand fireplace.
Glass doors open to a garden complete with sauna and cold plunge pool.

The home’s interior boasts crown mouldings, bespoke lighting, and layered textures throughout.
A custom Plain English kitchen includes an Officine Gullo range, Ann Sacks tiles, and a built-in banquette.
The primary suite occupies an entire floor, featuring more Zuber prints and Pierre Frey carpeting, along with a cosy seating area, fireplace, and walk-in closets.

The upper level contains two guest rooms, a skylit lounge, and a home office, while the garden level houses another guest suite, powder room, and family room.

The property features prominently in Allen’s new album, specifically in the title track “West End Girl,” where she sings: “So we went ahead and we bought it / Found ourselves a good mortgage / Billy Cotton got sorted / All the furniture ordered / I could never afford this / You were pushing it forward / Made me feel a bit awkward.”
The listing comes shortly after Allen confirmed their separation.
