Long, Narrow Board Look
Long, narrow boards used in deck tiles can really change the look and feel of a condo balcony. Compare this balcony with one that uses fewer boards and smaller tiles.
One isn't better than the other, they just show a different look and feel. On a large balcony (like above) it is often better to have your deck tiles built larger and use more boards in each tile. In the case above, I would normally recommend 6 in. boards (as opposed to 4 in. which are used here) as it will make it less "busy".
For a smaller balcony, narrower boards with fewer boards per tile will make this "parquet" look really come alive.
