  • Share this:

When buying a home, should it face south? We examine scientific research on sunlight benefits and ancient wisdom from Vastu and Feng Shui on the advantages of south-facing houses.

House Facing South - Science, Vastu Shastra, and Feng Shui POV


When searching for a new home, a common question is: "Which direction should it face for optimal benefits?" Many claim south-facing houses are best, based on science, Vastu Shastra, and Feng Shui principles. But what does each perspective reveal about the numerous advantages of south-facing homes?

Scientific Research Supporting the Benefits of South-Facing Houses

Modern science provides evidence-based benefits of south-facing homes through increased sunlight exposure:

  • Brighter, Warmer Living Spaces: South sides receive the most direct sunlight daily in the northern hemisphere, creating sun-filled interiors ideal for sunlight lovers. This passive solar gain warms homes in winter.
  • Immunity and Circadian Rhythm Alignment: Research shows sunlight helps balance circadian cycles for improved sleep quality and mood. It also triggers vitamin D production for immunity.
  • Enhanced Winter Heating and Energy Efficiency: Passive solar gain from south-facing windows can naturally heat homes during cold months, reducing heating costs.
  • Thriving Gardens and Outdoor Living Areas: With maximum sunlight access, gardens, patios and outdoor spaces prosper on the south side, great for gardeners and outdoor entertainers.
  • Preventing Seasonal Affective Disorder: Sunlight increases serotonin, helping prevent SAD, depression, and the "winter blues", especially beneficial for those prone to such conditions.
  • Added Visual Comfort: Strategic overhangs prevent summer solar glare and heat gain while allowing lower winter sun to enter and warm homes naturally.
