My Megaton house

 is a player residence in Megaton which becomes available after you disarm the bomb during 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 . The house includes a main floor lounge, a very small kitchenette, an upstairs landing, an undesignated room that Wadsworth often spends time in, and your bedroom.

Testament to how strict the residents of Megaton are about space in the town and allowing outsiders citizenship, they left one of the largest and nicest dwellings in town empty for an unknown period of time, while many unofficial residents stayed in the Common House or at Moriarty's, until somebody (the Lone Wanderer) proved themselves worthy of living there.

Amenities
You get a robot butler, Wadsworth, who is able to tell you science related jokes (and other kinds), supply you with purified water (he will give up to five bottles, then you must wait one week for him to recharge), 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 (or the heart-shaped bed if you bought the "Love Machine" theme from Craterside Supply), grants the player the "Well Rested" effect (+10% xp) for 12 hours from when he/she wakes. There are various places to store an infinite amount of items within the house including; two lockers, a fridge, a desk and a filing cabinet.

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 a My First Infirmary, Jukebox, My First Laboratory, Nuka-Cola Machine and a 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.

If you talk to Moira she can change the decor from a run down shack to one of the following themes: Raider, Wasteland Explorer, Vault, Science, Pre-War and Love Machine. You can't sell the themes back to her but you can always buy a new one. Players looking to obtain skill books from their themes will want to buy the Science (Nikola Tesla and You), and the Love Machine (Lying, Congressional Style) themes since they are the only two that offer this extra gift. These can only be obtained once, however.

Bugs

 * Be careful when sleeping upstairs if you have the Vault Theme and Fawkes as a companion. If you go into the room far enough, Fawkes will follow you and you will become stuck. The only way to solve this is by reloading a save or killing Fawkes, which can be difficult with Broken Steel.
 * Many of the storage containers are not secure and may randomly empty or restock default items. The only container previously thought to be secure is the set of lockers right next to the door, but multiple players have complained of these reseting as well. Sometimes the entire house resets at once. Nuka-Cola fridge is usually secure.(Confirmed)
 * The house themes may reset. While you may lose any items left outside of containers, it means you can get additional copies of items such as Nikola Tesla and You and Lying, Congressional Style with their respective themes.
 * If you climb onto your upstairs bed and go into the left hand side of the bed close to the wall, your character will get stuck forcing you to reload, turn clipping mode off in the console (tcl) or use an unarmed V.A.T.S attack against a companion or Wadsworth to teleport back to a safe position.
 * A Brotherhood of Steel Paladin or Crowley may randomly spawn inside the house.
 * Sometimes Wadsworth will get stuck in your room and you will not be able to access your bed or the file cabinet next to it (loading a previous save may work, or you can kill Wadsworth.)
 * If you blow up the motorcycle in the upstairs shack room, it will stay on fire forever, rendering the room almost unusable.
 * Items may teleport from the shack room to the left of the front door, but only if manipulated against another object.
 * If you blew up megaton during the quest Power of the Atom and you fast travel to the location known as megaton house megaton will be fine and the people will still be alive. (To be confirmed by more players)
