After completing a home renovation, I intentionally designed an awkward triangular space beneath the stairs to serve a special purpose, but my problem was that I wanted to turn this unfinished void into a cozy retreat, like a dedicated under-stair dog nook.
But I needed ideas on how to finish the interior to make it look intentionally designed, rather than like an abandoned space. Since my cat and dog are friends, I already installed climbing shelves for my cat next to the dog’s new space, so now I needed the dog’s area to be just as stylish and functional. While many suggested the dog wouldn’t care and I should just throw a bed in there, I knew the space would also be used by my friends’ children as a fun “hidey hole,” justifying the need for a polished look.
My ideal under-stair dog nook solution involved finishing the interior with more than just paint. The winning, budget-friendly idea was to use peel-and-stick wallpaper, a much cheaper and easier alternative to VJ panels, to add pattern and personality.
I also decided to install a battery-operated LED light purchased from Amazon and line the base with a washable mat for practicality and to make cleaning easy. I don’t want another daily task added to my household chores.
At the end, I wanted to transform my space into a cozy den that is durable for both dogs and my kids, so I will line the interior with stylish peel-and-stick wallpaper and install trim around the front opening to give it a neat, framed, “done” appearance.
For the floor, I will cover it with a washable dog bed or rustic mat to match my wall’s color and to transform the cozy nook, transformed from an awkward corner, into a charming under-stair dog nook that is both pet-friendly and aesthetically pleasing.
