Working today, I have placed spawners at random points throughout the world. I've used the cme mod and put many mobs into the world. I did this so people in survival mode would have a really wild experience. I've added railings onto multiple balconies and parts of the roof to allow stargazing or just viewing your world. I worked on the main bedroom located near the pool. I put in a desk, bookshelf, wiki, a bed (dur) lighting, and also built a passageway to the second floor bathroom. Later, I will add a first floor bathroom, a guestroom and a dining room.
Outside I used the not so simple bombs mod and literally threw a small house into the forest outside the property. After modifying this small home, I turned it into a gazette. I took out all four walls and replaced them with a wooden fence.

Here is a top view of the property so far. The gazette is not in this one...it's farther north. Pretty good, I must say.

The driveway. It splits off three ways-one to the main garage area, one to the secondary one, and the third (left) is a pathway to the front door.

Here is the secondary garage with the library on top of it. For garage doors I might use the Japanese doors in the home decor mod. There is a chest by the right side of the garage containing the doors.
I will most likely expand by building next to the garage with the library on top of it. I will add a guestroom, well, garden and a small farm where cows, sheep, horses, and chickens will live. I will then place gaurds and archers around the property. It's gonna be great.
I build buildings. I don't usually make mods...I use them.
