Focus on activating the north,south east, and west directions. Also,clear any Shailya dosha(structural imbalances).

As per Lord Viśwakarma, the Divine Architect, performing Shailyodwārat the Brahmasthan(central zone) is the key Vastu remedy for existing homes. This alone can harmonize the space. (Ref: Viśwakarma Prakāśa, 2.93

Keep the east direction clean and dosha-free. Ensure you’re getting60% protein,30% carbs, adequate water,regular exercise, and20 minutes of daily sunlight.

All directions belong to Lord Brahma and can bring prosperity if used wisely. The key lies in placing the entrance on the right pad. (Ref: VKP, Chapter onDvāra)

On the western wall.

Preferably on the Varuṇa pad (west), if your main entrance isn’t on the west. Alternatively, you can place it towards the north. (Ref:Jalāśayachapter, Viśwakarma Prakāśa)

According to Manushyalaya Chandrika(Chapter 7), ideal placements include the zones of Vāyu, Īśa, Parjanya, Jayant, Mahendra, Sūrya, Satya, Agni, Pūṣa, or Savitra.

Lockers are best placed on the north wall, or in the west,southwest, or southeast directions.
