My Megaton house

 is a player residence in Megaton which becomes available after you complete the The Power of the Atom quest. Sheriff Lucas Simms or his son Harden Simms (if the Sheriff has been killed) gives you the key to the house after disarming the nuclear bomb in the center of Megaton. At this point the "Empty House" turns into .

Amenities
You get a robot butler, Wadsworth, who is able to tell you jokes, supply you with Purified Water, cut your hair and explain what your home improvements are used for. If the player has purchased the infirmary Wadsworth will remind you to use it if you pass by him injured.

Sleeping in the bed on the second floor of the shack grants the player the "Well Rested" effect (+10% xp) for 12 hours.

The house also comes with random loot in the five containers. Two of them on the top floor in your "bedroom" (desk and file cabinet) and three on the first floor (two lockers opposite each other in the main area and the refrigerator in the "kitchen" cranny). These containers are proven safe places to store things, bugs excepted(see below).

Home Improvements
Once you are a resident of Megaton and proud owner of your own house, you can enhance your new home by adding various improvements which can be purchased from Moira at Craterside Supply.

You can improve your house with an infirmary, jukebox, laboratory, Nuka-Cola machine and workbench. All of these improvements add new functionality to your house which ranges from being able to heal yourself instantly and for free to simply being able to listen to music in your house without using your Pip-Boy radio.

It is also possible to change the decor from a run down shack to one of the following themes: Raider, Wasteland Explorer, Vault, Science, Pre-War and Love Machine (try to find the song "Love Shack" on the jukebox if you have the Love Machine scenery).

Besides pre-defined themes, a playful player can equip the shack with pretty much everything found in the wasteland, dropping items and arranging them with the drag key, or even with "guards", leaving them around and pushing by walking directly at them in desired location. However, the player must "renew" partnership whenever passing around in order to prevent companions from returning to pre-defined locations. This is useful if you have discovered and done nearly everything with the game and you are temporaraly bored, for Instance, I have every single Fat Man on display including the Experimental MIRV, all the improvements possible including The Pre-War Theme, over half the unique weapons, items and clothing in the game (including bobbleheads)and the worlds largest collection of Ophthalmoscopes.

Bugs
Getting Stuck: If you climb onto your bed and go into the left hand side of the bed (facing it) close to the wall, your character will get stuck, forcing you to load another save.
 * Disappearing items - Many of the storage containers are bugged and instead of all them being 'Secured' and safe to store things in, some of them will randomly empty (Lockers on the opposite end of the front door, Desk) or 'restock' default items (the fridge). The only container that always seems to properly secure itself is the set of lockers right next to the door.
 * Fix - One must open the console, click the locker/filing cabinet, and type  (case-sensitive) to check whether it is owned by the player.  If it is not, click the container and type   (case-sensitive).  One can verify whether it worked by clicking the container and typing   (case-sensitive) again.  Close the console to move to the next container and repeat.
 * There seems to be a strange occurrence with some players where some items left lying around the house (not in containers) will eventually be found to have been repaired completely after some time.
 * If you drop some items into your house (pre-war money) it will be classed as stolen.
