There is no definitive answer to this question as it can vary depending on the context and what is deemed important for the specific project. However, broadly speaking, finished space refers to an area within a building that has been completed to a certain standard and is ready for occupancy or use. This could include areas such as bedrooms, bathrooms, kitchens, living rooms, etc. that have been fitted out with all the necessary fixtures and fittings and meet any relevant building codes and regulations. In some cases, outdoor spaces such as gardens or patios may also be considered finished space.
