In anticipation of your next question. There are many options that you can choose. Too long to list. But your agent will tell you the only options you have is what they offer. One option(s) that you just don't find on the website is that you can (for at least Designer homes) you can add say two feet to either side, add to the lania 2 to 4 ft., add to the width and length of the garage as well.
We spent 3 days in TV 2/10 and after viewing models just priced the heck out of the house we liked. (Now of course we changed the model we like)
Looking forward to our Lifestyle visit next April when the wheels of moving to TV really start in motion.
By the way, I got the feel of what TV is all about just perusing TOTV for the last 15 months...
Good Luck!
