Like many HDBs, we have an awkward beam in our study room. We couldn't find a ready made shelf that fit perfectly, so we went along with this instead. There's still some gap, but we can probably live with this for now.
Here's our work area - we went with this configuration, just in case there's a need for both us to go on video calls on the same time! This will also give us a little more space in the middle of the room, but who knows we might change it up next time.
We created a small reading corner for us at the back of our study room. We used quite a number of pink furnishings in this room to match the wall colour haha
