03 — Design

The building
is an introvert.

Protective dark-brick façades fold inward to reveal light-filled, garden-facing interiors. Natural materials anchor a deliberately restrained architectural vocabulary.

The garden façade
where the fortress opens.

Floor-to-ceiling joinery, private terraces, whirlpool baths in every unit, and a shared pool at the heart of the plot.

04 — The Asset

Four residences. Two typologies.

Each unit is conceived as a standalone home within a multi-unit structure — independent entrance, private outdoor space, dedicated wellness.

Grounded.
Garden-facing. Private.

The Garden Villa opens across two levels with direct access to the landscaped garden. A vast ground-floor living space flows into a dedicated fitness room. Upstairs, three bedrooms cluster around a master suite with walk-in dressing and whirlpool bath.

Terraced. Skyward.

The Penthouse spreads over the upper two floors with a panoramic wrap-around terrace. A generous salon connects to an open kitchen and dining area. The top level contains a dedicated home office and a master suite with its own private terrace.

Garden-facing. Light-filled.

The mirror-image Garden Villa in Bloc B delivers an expansive 199.8 m² across two levels. Direct garden access, private fitness space, and a master suite that reads like a boutique hotel room — anchored by a whirlpool bath and dressing area.
