I had my 2 story, 4 bdrm home built in 1998 on my own 1/3 acre .... You should check with the county about sharing driveway, ask about septic system/perk test... If all that's good, and you decide upon house plans - you can inquire about extensions. I extended my house by 2 foot in one direction at that time it cost me $2750.00 for that extra 2feet...I decided against extending the center section of house due to my budget.... I had house plumbed for gas fireplace - still haven't installed one, but the gas line is right where I want it if I ever get enough cash to purchase the unit... I had extra outlets wired in every room, and close to ceiling for flat screen TV, it's a clean look, no cords hanging down...I installed all my surround sound wiring before drywall went up - again for clean look, radio shack speaker outlets .... I wish I had gas line plumbed to patio/deck area, could've converted my grill to run off LP gas instead of always filling propane bottles. . . . I've installed outlets on ceiling in my garage for those 4" fluorescent lights - nice and bright in my garage. . Only around 2,000 sq ft, white PVC fence cost me $4k in '98 ...two month after moving in I built my mini barn with concrete floor and overhead door to match house, to store motorcycles in
