A Christmas tree at a home in Winnipeg's River Heights neighbourhood is causing quite a buzz.

The tree inside Kate Pentney's house at 280 Ash Street appears to start on the main level and go through to the second floor and then out the roof.

Pentney said she got the idea from seeing it at other houses in Calgary and Europe. She said many people are stopping by and asking her about it.

"I've gotten a lot of, 'Did you cut a hole through your roof?'  And just, 'Uh, how'd you do it?' People are just curious," she said.

Pentney said they cut the tree to fit on each floor and attached the top of the tree to the roof to create the optical illusion.
