This study analyzed the relationship between the floor plan characteristics and the prices of officetels to determine the effect of the floor plan of small officetels on their prices. The study was based on 1,826 officetels completed in the last 8 years in three main districts (Gangnam, Seocho, and Songpa) in Seoul. The results of the study revealed that the one-room type, the typical floor plan of small officetels, did not have a significant impact on the price, but the long-range type, the floor plan of most small officetels, had a negative effect on the price. Additionally, the floor plan types with a separate shower room showed negative effects on the price, but those with a double-decker and a terrace showed a positive effect. This study is significant in that it analyzed the effect of the floor plan characteristics on the prices of small officetels, unlike the previous studies on the spatial composition, which mostly ended up with just case analyses. Finally, the research findings are expected to provide meaningful implications for the future floor plans and pricing of small officetels, and to assist prospective buyers in their decision-making regarding purchase.
