land sold with a building contract condition
A real estate term: the buyer must contract with a specific builder designated by the seller to construct a house on the purchased plot.
Since this property is land sold with a building contract condition, you must build the house with the designated construction company.
Standard spelling with okurigana 付き, commonly used in real estate contexts.
Variant without okurigana; seen in legal or formal documents, but less common in everyday writing.
Compound of 建築 (construction), 条件 (condition), 付き (attached), and 土地 (land). The term reflects a common practice in Japanese real estate where land sales are tied to building contracts.
