Here are some simple Jain‑dharma–based points to keep in mind while planning an expansion of a Jain temple (Derasar / Basadi):

1. Purpose and Bhav (intention)

- Keep the main goal clear: more shant, more upāsanā (worship), more swādhyāy (study) and better suvidhā (facilities) for sadharmi Jains. - Avoid “show-off” or competition with other temples. Luxurious decoration is secondary; shuddhā bhakti and discipline are primary.

1. Respect for Existing Pratimā & Garbhagruh

- The original garbhagruh (main sanctum) and mūl nāyak Bhagwan’s pratimā should always remain the highest in respect and central in layout. - New halls, rooms, side‑altars etc. should not “overshadow” the existing main pratimā in height or position, as far as possible.

1. Consultation with Āchārya / Pandit

- Before finalizing design, take guidance from a knowledgeable Jain Āchārya / Upādhyāy / learned Pandit of your tradition (Digambar or Shwetambar). - They can guide on: - proper direction of main doors and garbhagruh - where to keep upāśray, pāthshālā, bhojanshalā, yatra rooms, etc. - what not to combine (e.g., not mixing very worldly activities with temple premises).

1. Functional Areas to Consider

Depending on space and budget, people usually add: - Bigger bhakti hall / sabhā mandap for aartī, pravachan, and pūjā. - Pāthshālā rooms for Jain shikshan of children and elders. - Upāśray / sādhu–sādhvī niwās (if your tradition permits and you have āgya). - Library (granth bhandār) for scriptures and swādhyāy. - Dharamshālā / yatri rooms, separate from actual temple so that the mandir area stays more pavitra and quiet. - Proper facilities for old, disabled and children (ramps, clean toilets outside main mandir area, drinking water, etc.).

1. Shuddhi, Maryādā and Non‑violence

- Construction itself should try to follow ahimsā as much as possible: - Avoid unnecessary cutting of trees or harm to living beings. - Proper care in digging foundations; in some traditions, limited time of day, with stotra/recitation before starting work. - Materials: keep the mandir area clean, fragrance‑based (dhoop, agarbatti), free from meat, eggs, alcohol, etc. even in attached dharamshālā and bhojanshalā.

1. Separate Zones

- Keep clear separation between: - Pooja / darshan area - Study / meeting area - Residence / dining area - This helps maintain inner shanti and maryādā in the core temple space and reduces noise and disturbance near the garbhagruh.

1. Future Maintenance and Seva

- Plan expansion in such a way that: - Daily pooja, safāī, and security can be managed easily by the sangh. - Expenses of electricity, cleaning, staff etc. remain sustainable. - It is better to build slightly smaller but well‑maintained, than very large and later neglected.

1. Legal & Social Responsibility

- Take all legal permissions (municipal, building safety, fire safety) properly. Jain dharma emphasizes satya and aparigrah, so avoid any illegal encroachment or disputes. - Ensure parking and crowd management so that neighbours are not disturbed; this itself becomes a form of lok‑kalyān.

1. Pratishthā / Anjanshalā

- If new pratimās or new garbhagruh are planned, do not proceed casually. - Follow proper Jain scriptural rituals of pratishthā under guidance of your sampradāy’s ācārya or authorized vidhikār.

If you tell me:

• Which tradition (Digambar / Shwetambar, and which sect), and
• What kind of expansion you are thinking of (bigger hall, new floor, dharamshālā, pāthshālā, etc.),

then I can suggest a simple, step‑wise outline more specific to your case.
