Here are the key points from this page on HDB Melody Spring Yishun BTO and Feng Shui case studies:

• Development Overview

  • Melody Spring BTO launched in August 2018, with lease commencement dates in 2020–2021.

  • Initial appeal included unblocked sea and reservoir views, but future high-rise projects may obstruct them.

  • Some residents faced construction noise and dust soon after moving in.

• Unit Selection Concerns

  • Certain units face rubbish bin chutes directly (red zone), or are in close proximity (yellow/green zones). These are considered undesirable.

  • Units near drop-off point rooflines risk “Sha Qi” (poison arrows) if roof edges slice toward windows.

• Temple Case Study

  • A future Chinese temple beside Melody Spring raises Feng Shui concerns.

  • Units in the NE zone may be affected by the “Devil’s Gate” (considered unlucky). Placement of altars facing NE–SW could act as portals for spirits.

  • Burning offerings at the temple may cause smoke/fume issues depending on wind direction.

  • Both Chinese Feng Shui and Indian Vastu principles highlight risks of NE alignment.

• Precinct Pavilion (PP) Issues

  • Units near or facing the PP may be exposed to wakes, funerals, or religious chanting, especially during festive periods.

• Altar Placement Guidance

  • NE-facing units are particularly sensitive. Aligning altars NE–SW is discouraged due to susceptibility to negative influences.

  • These principles apply not only to Melody Spring but also to other developments with similar orientations.

• General Advice

  • Buying decisions should consider multiple Feng Shui disciplines: shapes and forms, poison arrows, Flying Stars, Eight House theory.

  • Melody Spring was initially under-subscribed, requiring a second launch in November 2018.

In short: the page highlights practical Feng Shui risks tied to rubbish chute placement, temple alignment, altar orientation, roofline angles, and proximity to precinct pavilions. It emphasizes careful unit selection to avoid long-term negative effects.
