This game is a scam, their main goal is forcing you to spend real money. They have reduced all rewards, they made it very hard to earn gold and nice materials all cost gold. If you are not willing to spend (quite a lot of cash) you will only end up with really ugly designs. Rooms and materials are very unprofessional and out dated. Lots of repetitive designs. If you are looking for a truly great design game I suggest Home Design Star, which is free, modern and the materials are awesome.
