A house temple (Ghar Derasar or Griha Chaityalaya) is a private Jain shrine that is placed within a personal residence.Jaina iconography: The Tīrthaṅkara in Jaina scriptures, art and rituals, Part 1, Jyotindra Jain, Eberhard Fischer, BRILL, 1978, p17.Jain Pratima Vigyan, Balchandra Jain Sahityashastri, Jabalpur, 1974, p.14 Sometimes it is separate room or structure in a compound.
Jain scholars prescribe that the height of a pratima in a house shrine should not exceed 11 aṅgulas, i.e. about 21 cm.
The formal communal temple is often referred to as a shikharbandi Jinalaya, i.e. with a shikhara. Sometimes a temple starts as a house temple, which grows into a formal shikharbandi Jinalaya when the community grows to be sufficiently large.As Mumbai Jain temple wraps up celebrations, silence shrouds its predecessor in Pakistan Yashwant K. Malaiya, Express Tribune, May 18, 2012 श्री गोड़ी पार्श्वनाथ, Acharya Vimal Sagar Suri, शेठ अमीचंदभाई ने आराधना के लिए अपने घर में गृह जिनालय बनाया था।
Jain author Haribhadra Suri states in one of his famous granthas, Sambodh Prakran that if a lay person has savings more than 100 rupees, then there must be a Ghar derasar at his/her home. Further he says that the house which does not have a Ghar derasar is not a home, it is a graveyard.
In that derasar, an image of a Tirthankara must be installed, on which the rituals of anjanashalaka (Panch Kalyanaka Pratishtha Mahotsava) must be done.
