Beau House Penthouse
The sculptural wall, which spans the entirety of this three-floor property, forms a dramatic centrepiece through the heart of the penthouse. Crafted in polished plaster, the faceted surface is comprised of striking geometric shapes. This is further accentuated by the reflection of the polished Namibia marble flooring and natural light which floods in from the glass roof above, creating a mesmerising interplay of light and shadow.
