There is no "Homescapes site" that offers official support. The only (official) ways to play Homescapes are the mobile version and the MAC version.

Dolly, if you got your information from someone on facebook, on the Homescapes' fb page, i can assure you that these people you mentioned were not part of the playrix team.

And as i said above, both version of the game (mobile/MAC) are, and will be supported in the future, so don't worry about that. A new update for the MAC version is coming soon!
