Spatial Optimization & 3D Visualizations

Singapore apartment floor plates present unique challenges: compact kitchen corridors, structural household shelters (bomb shelters), and tight hallway clearances. We treat space planning as an architectural discipline:

✓ HDB Wall Hacking & Reconfiguration: Converting closed galleys into airy open-concept dry/wet kitchen layouts with compliant permits.
✓ Photorealistic 3D Renderings: Accurate material textures, artificial cove illumination, and true natural sun simulation to visualize your space before carpentry fabrication.
✓ Circulation & Storage Ergonomics: Ensuring generous 900mm–1000mm walkway clearances even when integrating extended 3-meter kitchen islands.

✓ Premium Blum Hardware: Soft-close hinges, heavy-duty drawer runners, and touch-latch systems rated for 200,000 operational cycles.
