23 floor open-air swimming pool plan

Quick answer：

An open-air swimming pool on the 23rd floor of a building typically refers to a swimming pool designed to be situated at a higher level of a building, often with a panoramic view. The 'plan' refers to the architectural layout or design of the pool area. This could include the dimensions of the pool, surrounding facilities like loungers or sun decks, and any safety features such as barriers or lifeguard stations. The planning and construction of such a feature require careful consideration of structural integrity, safety regulations, and access to the pool area.
