Hi Milind!
How nice to have a visit from lions who were there to serve and protect you! Not everything is textbook, in fact it's rare it is textbook because the symbology is based solely on how the dreamer perceives what's happening and the objects they place emphasis on.
I'd say this is a very good dream for you. To most people, lions can be intimidating, frightening and predatory. None of these lions according to your feelings towards these animals reflect that. What you do say is you weren't threatened by them.
For some lions represent grace, stealth, majesty, courage and strength. The dream suggests one, some of or all of those feelings: grace, stealth, majesty, courage and strength. You had a pride of lions surrounding your house which would be indicative of protection, and safety.
The dream means these characteristics are developing within you or you are being asked to exercise the strengths above such as courage and strength.
Happy dreaming!
