Townlife Future Research Institute (Townlife Co., Ltd.) analyzed 152,153 valid inquiries received by its custom-built home matching service "Townlife Ie-zukuri" from April 2024 to April 2026, and announced the distribution of desired land sizes and preferences by desired number of floors for custom-built home seekers.

Executive Summary

1st place for desired land size: "Around 30 tsubo" (25.6% / 38,937 cases), 2nd place: "Undecided" (21.5%), 3rd place: "Around 50 tsubo" (19.0%)

Top 3 categories account for 66.1% of the total – concentrated in 30 tsubo, 50 tsubo, and Undecided.

11.1% of single-story home seekers desire "100 tsubo or more" – approximately double that of two-story homes (5.6%), indicating a preference for larger plots.

Three-story home seekers show a preference for smaller lots, with 34.1% desiring "around 30 tsubo" and 8.9% desiring "around 20 tsubo."

The high percentage of "Undecided" responses (21.5%) suggests the presence of early-stage consideration.

Main Survey Findings

1. Top 3 Desired Land Sizes – 30 Tsubo, Undecided, and 50 Tsubo Account for 66.1% of the Total

Analysis of the desired land size distribution for custom-built home seekers shows that "around 30 tsubo" accounted for 38,937 cases (25.6%), "Undecided" for 32,688 cases (21.5%), "around 50 tsubo" for 28,925 cases (19.0%), "around 40 tsubo" for 14,643 cases (9.6%), "around 70 tsubo" for 13,035 cases (8.6%), and "100 tsubo or more" for 11,305 cases (7.4%). The top 3 categories alone account for 66.1% of the total, indicating that users of our service concentrate their desired land sizes in the 30 tsubo and 50 tsubo ranges, or are undecided (in the early stages of consideration).

2. 11.1% of Single-Story Home Seekers Desire "100 Tsubo or More," Approximately Double That of Two-Story Homes (5.6%)

Comparing the land size composition ratios by desired number of floors revealed differences in land size preferences between those seeking single-story and two-story homes.

The table extracts only the main land size categories. Totals for each row do not sum to 100% as undecided, around 40 tsubo, around 60 tsubo, etc., are included. *

The proportion of single-story home seekers desiring 100 tsubo or more (11.1%) is approximately double that of two-story home seekers (5.6%). Single-story homes generally require more land than homes of the same floor area, which is one reason why those seeking single-story homes tend to prefer larger plots. However, it should be noted that this data indicates the land size "desired" by consideration, not the actual area required, and what can be understood here is the "correlation between those choosing single-story homes and a preference for large plots." On the other hand, three-story home seekers show a preference for smaller lots, with 34.1% desiring around 30 tsubo and 8.9% desiring around 20 tsubo, suggesting that three-story homes may be chosen as a solution for limited land in urban areas.

Figure 2: Land Size Composition by Desired Number of Floors. Three-story homes are concentrated in small lots of 20-30 tsubo, while single-story homes are biased towards 100 tsubo or more.

Discussion – Tendency for Desired Number of Floors and Desired Land Size to Correlate

The results of this survey indicate a tendency for the "desired number of floors" and "desired land size" of custom-built home seekers to correlate.

Seekers who desire single-story homes also tend to prefer larger plots, while those who desire three-story homes tend to prefer structures that can be built on small lots. Two-story homes are balanced across the 30-50 tsubo range as a middle ground.

In product design, instead of treating land size and building height as independent variables, presenting them as combined packages such as "30 tsubo x two-story," "50 tsubo x two-story," "100 tsubo x single-story," and "20-30 tsubo x three-story" would be more compatible with the natural decision-making patterns of seekers.

Implications for the Industry

This survey suggests the following to home builders, remodelers, and real estate agents:

Combination Products of Land Size x Number of Floors: Support decision-making with package proposals, not just individual attributes.

Strengthened Land Acquisition for "100 Tsubo or More" for Single-Story Homes: Securing large plots is crucial for selling single-story homes.

Three-Story Homes as the Core of Urban Small Lot Strategy: The market for around 30 tsubo and around 20 tsubo is the main target.

Land Proposal Services for the "Undecided" 21.5% Segment: Differentiate by providing land search support for early-stage consideration.

Future Outlook

Townlife Future Research Institute plans to further delve into the land size preferences confirmed in this survey and will sequentially release follow-up reports on "Combination of Land Size x Building Budget," "Desired Land Size by Prefecture," and "Desired Specification Trends by Land Size."
