Haven't heard of B&B.
A friend at work built with Maronda and had problems.
My husband and I looked at a Maronda community while house shopping a few months ago. First of all, they don't deal with real estate agents at all, says it keeps their costs down. Also, when you go look at houses, you are looking at the actual houses that people will be buying. We picked the model that we liked and then were told which lot numbers had that specific house. Depending on how far along construction is when you decide you want that house, you may or may not be able to pick colors, cabinets, etc. Isn't that part of the reason for building a brand new house? The thing that put us over the top was when the lady showing the house told us she'd rather us pay a cheaper house so we had money left over for flowers and landscaping then spend all our money on the house we wanted. What?! We left and never looked back.
