I purchased my first home from Branthaven and really regret buying it from this builder. Not only do i feel like i made a poor investment, they have rid me of all excitment of purchasing my first home. When driving by i noticed the back of my house was not bricked. I called customer care and that is when I was told the rear elevation would be 75% vinyl siding. Keep in mind the front elevation is majority siding as well. They did not provide a rear elevation drawing of my unit in the purchase aggreement which i am sure they did on purpose. Although i was told this was done for aesthetic purposes, it was done to cut cost! That kind of workmanship is below standard for a newly built home and i actually feel bamboozled!
