Have a 4 bedroom home with 2 down & 2 up. Would adding a gameroom over the garage be cost effective?Home is 3.5 yrs old, 3400 sq ft and in a family-oriented neighborhood. We don't need the space, but are thinking about resaleability down the road. Are game room additions, such as 15X20 plus 1/2 bath worth adding?March 06 2010 - Highland Village00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
