For 11 months of the year, Pam McIntosh and Sharon Williams live in a comfortable home that is not remarkably different to any other on their High Wycombe street.
But come December, the couple surrender their house to the Christmas spirit, filling the rooms with decorations and covering the front yard with sleighs and reindeer.
What started as a row of gutter lights nine years ago has since turned into a winter wonderland so big it takes up almost half of their Edney Road home.
Ms McIntosh said a new North Pole-themed room had been added to the mix this year, making the decorations bigger and better than ever.
"It's a challenge but we enjoy doing something different each year and putting some of our own creativity into it," she said.
"The set-up probably takes about a month but because we work we have to build it up at night and over the weekends."
The displays take months of planning and attract hundreds of people from all over Perth to the street each year.
For the past three years, Ms McIntosh and Ms Williams have also been collecting donations for Princess Margaret Hospital from visitors.
Ms McIntosh said while they may have gone "a little bit overboard" this year, it was all worth it when they saw the joy on their visitors' faces. "It's such a fun time of year for the kids and we really enjoy it as well," she said.
