Architectural Designation - House B is designated as KeyPrice Signature Architecture in recognition of its disciplined contemporary design, sculptural concrete composition and sophisticated environmental response. Designed by Daffonchio Architects, the residence demonstrates how minimalist architecture can achieve extraordinary presence through precision rather than excess. Positioned within the prestigious Steyn City Estate, the home frames sweeping views across golf fairways and landscaped parklands while presenting an elegant composition of floating concrete volumes, expansive glazing and finely detailed architectural screening.

The residence is conceived as two offset concrete forms that appear to hover above one another, creating a powerful interplay between solidity and lightness. The lower level is defined by transparent living spaces that dissolve into landscaped terraces through fully retractable glass walls, while the upper bedroom pavilion appears to float effortlessly above, separated by a dramatic shadow line. A laser-cut aluminium façade wraps sections of the building, simultaneously providing privacy, passive solar protection and an ever-changing architectural identity. Inside, a restrained palette of off-shutter concrete, bronze aluminium, timber and glass establishes calm, gallery-like interiors where natural light and the owners' curated art collection become integral elements of the architectural experience.

Rather than relying on ornament, House B expresses luxury through proportion, craftsmanship and environmental performance. Every detail—from the chamfered concrete edges to the seamless indoor-outdoor transitions—reflects a refined architectural discipline that has become synonymous with Daffonchio Architects' residential work. The result is a home that feels timeless, sophisticated and deeply connected to both its landscape and Johannesburg's contemporary luxury lifestyle.
