We used Jim Lane as our designer thru our realtor. He was great! Remember, they don't always ask you what you want, don't be afraid to ask. We built a Gardenia, make several stretches and changes. We asked for these options and sometime he would say, I don't know lets ask, everytime they approved the stretches and changes. That's if your lot will abide. If your lot is big enough and you can spare the exra money, expand your lanai and garage. We pushed both sides out as well and glad we did!
Good luck, and if you can get Jim Lane as your designer you won't be sorry. Great man to deal with!
