We have an amazing designer that has drawn our house remodeling / addition plans in 2d. However, I'm having a really hard time visualizing everything and feel nervous making huge decisions without seeing it in 3d. The primary concerns are 1) a home addition plus garage addition - how far back or forward to place it relative to the current home (we want it to have dimension and I'm having trouble determining dimension on a 2d drawing), 2) kitchen design, 3) mudroom / laundry room design.

I've played around with free programs and I'm not very good at it. I still feel unsure. How does one go about finding someone to take the plans and convert them to 3d? What is the cost of something like this?

Thank you in advance!
