I like the single level layout, which is very similar to my previous home. I also like the exterior color, flooring and fireplace.
More design options, better communication between agent, project manager and home buyer, more flexibility with regard to certain needs (walk in shower in place of tub, for example), more insulation since my house is usually cold, increased water pressure, quicker (any) response from warranty since I submitted a request Jan 2 and have yet to hear from someone on the work, and overall better quality of workmanship.
I wish the interior doors were just a little wider, we had trouble getting some furniture in.
I love the open design and the wide hallway. I love the master bathroom - I feel like I'm in a spa
