John Mayer wants to create a "sanctuary" for himself and Katy Perry
The womanising rocker - who has previously dated a bevy of famous women including Jennifer Aniston, Cameron Diaz and Jessica Simpson - thinks the `Firework` hitmaker is "the one" for him and he is keen to move in with her as soon as possible.
A source told HollywoodLife.com: "Johnwants to take his relationship with Katy to the next level.
"He has suggested to Katy that they get a place of their own. He feels like she`s the one for him and wants to commit himself fully.
"John is really into architecture and wants to create a `sanctuary` for himself and Katy."
The couple have been dating for six months and for Christmas, 35-year-old John presented the pop star - who was previously married to Russell Brand - with a custom-designed guitar to show his love for her.
A source said last month: "John has put some serious effort into his Christmas gift for Katy.
"Since they met he has been trying to prove he isn`t the guy everyone says he is.
"This should definitely prove that - every little detail on the guitar shows how much he thinks of her."
The musician had the guitar covered in intricate designs, including 28-year-old Katy`s initials and the date they first met.
The couple - who had a brief split last October before getting back together - are smitten with each other and like to spend every moment they can together.
One source said: "They are together virtually every day.
"They hang out at John`s place, cooking, watching movies and playing music.
"They take the odd trip away but generally they`re trying to keep it behind closed doors."
