It is a touch on the small size, but as
@NashansCamos mentioned with free range it will be fine.
I have thought of a set up like this for people like you that have space constraints. Here are some of my observations ant thoughts.
As back ground on this I have very large open setups. The animals can leave the enclosure if they so choose. I did this so I could as best as possible observe their behavior as it would be in nature. (at least as close as I can come in my house)
Since it is a male, I actually think it may make it a little easier. Here's why, my female seems more territory oriented in that she prefers to stay in her given area. Her enclosure is about 6ft x 6ft x 3ft, and though her preferd spot has changed, it still only occupies about the size you are stating. Thought this is open area, so it is a bit different.
So with the male. He spends usually 1 to 3 days just chillin. moves around some mostly looking for food or a good spot. But on the other days he is ready to explore.
Given this behavior, if he gets plenty of explore time.
The next aspect would be , Don't over "decorate" the cage. Though it often looks quite beautiful, it is not where they choose to be. Again from my observations they do not like the areas thick with branches. They both prefer to actually sit in the more open areas. For hiding, both again if given the option do not hide in the thick of the leaves but rather behind them. They both have "open" space behind the thick parts of the leaves.
Utilizing this, if I were going to set up a smaller enclosure.
1) No bushy plants , this is wasted space. You definitely want plants though, pathos is a good choice, but the get eaten. "Palm" type plants are good as they do not seem to get eaten as much.
2) For a large male in a smaller cage I would have very few branches. Realize they can easily stretch their body length to the next branch.
3) I would add a large plant out side the cage arranged in such a way as to partaialy "hide the cage. This will add to his hiding area.
4) Open his cage frequently and let him explore.
5) With the exploration it will be important that you make sure he is still getting enough time under UV and in proper humidity for his species.
