■ Condensing the Ease of One-Story Living and Practical Space into 25 Tsubo
The 'FLAT-X' model house is a popular product from Ace Home that launched in November 2023. While based on a one-story (flat) layout, it incorporates skip floors and large-scale storage to create spacious living within a limited footprint. This specific model features a 3LDK+S (3 bedrooms, living, dining, kitchen + storage) plan with a total floor area of 25.33 tsubo (approx. 83.7 sqm). It is designed for modern dual-income families, featuring a dedicated laundry room, shoe closet, and independent vanity area, balancing storage capacity, housework flow, and comfort.

■ Highlights of the 'FLAT-X' Model House
FLAT-X is designed for those who refuse to compromise on storage, housework ease, and safety.

1. Skip Floor for Vertical Space Extension: Solves the common storage and spatial limitations of one-story homes by utilizing vertical space. The area under the skip floor provides extra living and storage utility.
2. 'Miracle Big Storage' with 25%+ Storage Ratio: By fully utilizing the space under skip floors, the design secures over 25% storage ratio—significantly higher than standard homes. It accommodates large items, seasonal goods, and daily stock, helping keep the home tidy.
3. Housework-Saving Flow: Kitchen, laundry, and vanity areas are placed in close proximity. This continuous flow allows users to multi-task efficiently, such as laundry and cooking, reducing the daily burden.
4. 'Super Seismic Suppression' and High Insulation: Combines Seismic Grade 3 with vibration control technology to withstand repeated tremors. High-performance windows and insulation tailored to local climates ensure comfort and lower running costs year-round.
