Welcome to GJ.
Please put your location in your profile.
Please don't plop a pre-planned house plan down on a lot.
Instead, have a plan developed, that fits your lot, and the functions and needs that you and your family have.
This can result in a home that fits you, much like a custom suit fits much better than a suit off the rack.
The plan you linked to, is a pretty picture with lots of curb appeal. But without knowing how it works with your lot, it's a **** shoot whether it will work well, or not.
What's your lot like?
What is the zoning and what are the zoning rules?
What is your budget? Work from that, backwards toward what can be done.
