In light of the above, E, an urban-type residential housing, is not capable of constructing three spaces from the conclusion of the above supply contract, since E, which is an urban-type residential housing, should consist of a single space with the exception of boiler rooms, and can constitute two spaces in cases where the exclusive residential area is at least 30 square meters.

After that, on April 5, 2017, the Defendant and the Intervenor confirmed from the Seopopo City on April 5, 2017 that the measures for advertising and model voucher operation have been completed with three compositions.
