You could use the word Bait (house) added to any good attribute, as in:
Baitul Ihsan (house of good deeds)
Baitul Iman (house of faith in Allah)
Baitul Rida (a house in which Allah's pleasure is gained)
Baitul Huda (house of guidance)
Rauda/Rauza (garden, flowering meadow, mentioned in Quran 42:22)
Nima and Ataa (gift from Allah)
If you are looking for a particular meaning, you could submit it in another question and inshAllah I will give you words in Arabic close to that meaning.
