I have decided to enclose the carport so I can have a small home gym. The carport is adjacent to a smaller house on the property, so it seemed most sensible to lay a wooden floor structure in that part as well if you want to increase the area inside that house in the future. See drawing.
The new part will be used as a gym/office. And after some searching here on the forum, I saw that there is something called EPS concrete? Is it suitable to use in this case?
If yes, could you roll out a gym mat directly on the EPS concrete?
And lastly, will this solution be more expensive than pouring a slab? I have received a quote of 36' for a 120mm slab with 100mm insulation.
What I want is a strong durable floor suitable for a gym.
