• Location: 21 Jalan Sempadan, Singapore

Design Concept: Modern Minimalism with Architectural Depth

The design direction focuses on clean lines, layered textures, and neutral tones to create a luxurious yet understated atmosphere. Instead of visual clutter, the space relies on proportion, lighting, and material contrasts to express elegance.
 

In the living area, full-height feature walls, warm wood accents, and marble finishes anchor the space while maintaining a calm visual flow. Custom carpentry elements are designed to integrate storage discreetly, ensuring the penthouse feels open and uncluttered despite its functional requirements.

A sculptural staircase becomes a statement feature, connecting levels seamlessly while enhancing the architectural character of the home — a key hallmark of high-end condo penthouse interior design in Singapore.
 

Kitchen & Dining: Functional Luxury

The kitchen reflects the same modern minimalistic language, with matte cabinetry, concealed handles, and premium stone finishes. Integrated appliances and clean cabinetry lines allow the kitchen to blend effortlessly into the overall interior, rather than feeling like a separate utility space.
 

Lighting plays a crucial role here — under-cabinet illumination and recessed ceiling lights enhance functionality while elevating the overall ambience.
