The sofa fits, the television fits, and the basement post sits right where you'd like to walk. Boxing it neatly is one answer; folding it into a useful partition is another. Before adding a whole wall to hide it, try the smaller enclosure with your actual furniture. The post may be less trouble than the room you've drawn around it.
Keep the support on every drawing
Mark the post, beam, visible base, and relevant services accurately. Treat them as existing structural constraints unless an engineer has designed and approved a change through the applicable process. Decorative boxing does not authorize cutting, moving, or altering the support.
Try a small enclosure first. In a basement family room, we taped the finished box around the post and set the sofa behind it. The post looked much less intrusive once the furniture was in place. Then the owners tried their recliner and found the footrest crossed the walking route. Moving the sofa a little solved that conflict without creating a whole new room around the column.
Make the wall earn its length
A partition can absorb the column into a storage room, laundry boundary, or deliberate room division. Draw the whole wall, its doors, and the space it takes from each side. Do not build a room nobody needs just to hide one post.
A shorter return or fitted element may provide visual order without closing the basement entirely. For that room we kept the compact enclosure and used a low storage piece nearby, leaving the walking route open. We also accounted for the post base when sizing the box; measuring only the slim shaft would have understated the finished footprint. Coordinate required access, structural protection, and finish details before making the enclosure as small as it looks on paper.
Check the project, not just the enclosure
Toronto’s building permit guidance identifies wall and structural alterations as approval questions. Confirm the scope with the local municipality and designer; adding a partition can affect more than the appearance.
Choose a compact enclosure when keeping the room open makes the furniture and routes work. Add a partition when you actually need the room or storage it creates. Before fixing either layout, look up as well: the basement ceiling choice needs to account for the beam above that post and the services around it. The box, wall, and ceiling should make sense together.
