a second unit that constitutes a floor above the first unit out of the plurality of floors; and
a space path that is disposed in the first unit and the second unit,
wherein the first unit and the second unit each include a building structure having a first wall, and the space path is arranged on an interior side of the first wall,
the space path includes an upper and lower floor air circulation duct that is installed to extend over the first unit and the second unit, and an air supply and exhaust duct that is installed to extend over the first unit and the second unit,
the upper and lower floor air circulation duct is a circulation duct which includes a circulation fan,
the air supply and exhaust duct is connected to a ventilation opening via a total heat exchanger, the ventilation opening being provided in the second unit and communicating with an outdoor space,
the upper and lower floor air circulation duct includes a first air circulation duct installed in the first unit and a second air circulation duct installed in the second unit,
the first air circulation duct and the second air circulation duct are connected at a portion linking the first unit and the second unit,
the first air circulation duct communicates with an indoor space of the first unit and the second air circulation duct communicates with an indoor space of the second unit,
at least one of the first air circulation duct and the second air circulation duct communicates with an outdoor space of at least one of the first unit and the second unit,
the air supply and exhaust duct includes a first air supply and exhaust duct installed in the first unit and a second air supply and exhaust duct installed in the second unit,
the first air supply and exhaust duct and the second air supply and exhaust duct are connected at the portion linking the first unit and the second unit,
the first air supply and exhaust duct communicates with the indoor space and an outdoor space of the first unit and the second air supply and exhaust duct communicates with the indoor space and an outdoor space of the second unit, and
the upper and lower floor air circulation duct and the air supply and exhaust duct are spatially connected, and wherein the first unit has a ceiling bosom and a recessed portion defining the outdoor space, a part of the ceiling bosom being arranged above the recessed portion, the ceiling bosom includes a space between a ceiling base sheet of the first unit and an upper beam of the first unit, and the space path is disposed to pass through the part of the ceiling bosom.

2. The building unit according to claim 1 ,
wherein each building structure has at least a second, third and fourth wall and is surrounded by the first, second, third and fourth walls,
the first, second, third and fourth walls each include a face on an outdoor side serving as an outer wall face, and a face on an indoor side serving as an inner wall face, and
the space path is disposed in a vicinity of the face on the indoor side.

3. The building unit according to claim 2 ,
wherein a distribution board is installed in the face on the indoor side of one of the first unit and the second unit.

4. The building unit according to claim 1 ,
wherein an electrical wire is installed in the space path.

5. The building unit according to claim 1 ,
wherein the building unit further comprises a duct space area, in which the duct is installed, and
wherein the duct space area extends in a vertical direction over the first unit and the second unit.

6. The building unit according to claim 1 , further comprising
water-related equipment,
wherein the water-related equipment includes at least one of a bath, a toilet, a washstand, a kitchen, or a hot-water supplier, and
the space path is provided in a vicinity of the water-related equipment.

7. A building comprising:
the building unit according to claim 1 installed at a building site; and
