From the quality of the pictures, you can tell that the lighting is bad. But for a reading and play nook under the stairs, it works just fine.
The massive oak staircase is going to be replaced at some point so for now it was a matter of making the most of a totally weird and unused space. You should have seen the way it was staged while on the market! I should have taken a picture!
Everything was transplanted from the reading nook in our rented house, plus I added some IKEA shelves and papa built a swing. A lamp, a toy chest and some toys - just about write for our little man.
