We did this in 2013.
There may be limits in the size of the house, as there are build lines that the home cannot exceed. Ours hit these in 2 corners (pie shaped lot. Get a plot plan.
We tried to have the home realigned 5 degrees or so to miss one of the limitations and this was NOT allowed.
When we bought the lot we were told building had to start within 6 months.
As I recall there was no limitation on the style of house, but we were only interested in one style.
There are limitations on the location of the house on the lot so all of the houses line up correctly.
Our agent asked if we wanted a pool, as the lot was a little small for a pool, we said no, and later added 800 square feet of birdcage.
If your lot backs up to another road, there may be a utility corridor that could be 20 feet wide (no build zone).
The color of our house was open for us, as we built before the houses on either side built, as I recall they would not allow 2 houses with the same (or very similar?) paint schemes next to each other.
There were standard locations for potable water, irrigation water, and sewer, all of these should shown on the plot plan for the lot. You should be able to get this from the county.
Hope this helps.
