Business

Grandi House was founded in 1991 in Utsunomiya City, Tochigi Prefecture, and is one of the largest detached housing builders in northern Kanto, with consolidated net sales of ¥52,981 million for FY2026 (ending March 2026). In its core Real Estate Sales segment, the company handles everything in-house as a group, from acquisition of land for residential development through land improvement, housing design, construction, sales, and after-sales maintenance. It operates regional holding subsidiaries in Tochigi, Ibaraki, Gunma, Chiba, Saitama, and Kanagawa prefectures, and in February 2026 opened a Mitaka branch in Musashino City, Tokyo, to accelerate its expansion into the Tokyo metropolitan area. The company also operates a stock business covering Used Home Sales and renovation, a Building Materials Sales business for the manufacture and sale of Precut Materials, and a Real Estate Leasing business covering rental housing and parking, building a diversified portfolio of housing-related businesses.

Business Model

Grandy House has adopted a vertically integrated business model in which land acquisition for housing development, development permitting, land improvement, design, construction, sales, and after-sales maintenance are all completed in-house within the group, thereby internalizing profits at each stage. The main revenue source is the sale of New Detached Housing (For Sale) (the Real Estate Sales segment accounts for approximately 94% of net sales in FY2026 (ending March 2026)), while the stock business comprising Used Home Sales and Home Renovation & After-Sales Maintenance generates complementary revenue by leveraging the existing customer base. Building Materials Sales (through subsidiary General Rib Tech) functions both as an internal group supplier and for external sales, while Real Estate Leasing provides stable cash flow.

Company Strengths

In the 2026 Oricon Customer Satisfaction Survey, the company ranked No.1 in the North Kanto detached housing builder category for the 7th consecutive year. It has continuously developed high-value-added products, including standard installation of seismic control dampers on all units (for construction starting from May 2025), introduction of the "60-Year Warranty & 60-Year Support System" (November 2025), and promotion of ZEH housing and Ohisama Eco-Cute water heater installations.

The company has built a system in which land acquisition for housing lots, development permits, land development, housing design, construction, sales, and after-sales maintenance are all handled in-house within the group. Including in-house supply of Precut Materials by subsidiary General Rib Tech, the company has achieved cost and quality control with minimal reliance on external parties. As a result of thorough inventory and expense management, segment profit for FY2026 (ending March 2026) increased 111.3% year on year.

The company has established regional holding subsidiaries in Tochigi, Ibaraki, Gunma, Chiba, Saitama, and Kanagawa prefectures, building development and sales structures tailored to each trading area. In February 2026, it newly opened the Mitaka branch (Musashino City, Tokyo) to strengthen its Greater Tokyo area business. In FY2026 (ending March 2026), combined sales in the Greater Tokyo area (Chiba, Saitama, and Kanagawa) totaled ¥17,100,794 thousand, accounting for approximately 34% of total Real Estate Sales, giving the company resilience against demand fluctuations through regional diversification.

ENVALITH's Perspective

Although operating profit of ¥1,892 million and ordinary profit of ¥1,485 million in FY2026 (ending March 2026) improved significantly year on year, they remain less than half of the peak level (FY2022 (ending March 2022): operating profit of ¥4,023 million). Net sales of ¥52,980 million also fell short of the ¥54,885 million recorded in FY2022 (ending March 2022), and a full-fledged recovery in profitability will require both an increase in the number of units sold and the maintenance of unit prices.

As an external factor, housing starts for detached housing for sale remained weak, down 5.9% year on year for the full FY2026 (ending March 2026), against a backdrop of persistently high housing prices. The number of new homes sold stagnated at 1,219 units (down 54 units year on year), and future performance will hinge on whether the expansion of business in the Greater Tokyo area, using the Mitaka Branch as a foothold, can produce results in both unit volume and unit price. Achieving the FY2027 (ending March 2027) forecast of net sales of ¥58,000 million (up 9.5% year on year) is premised on an early ramp-up in the Greater Tokyo area.

The Building Materials Sales segment swung to a segment loss of ¥4 million in FY2026 (ending March 2026), from a segment profit of ¥62 million in the previous fiscal year. The main cause was an increase in depreciation expenses associated with the renewal of production equipment (depreciation expenses for this segment surged from ¥33 million in the previous fiscal year to ¥108 million). This will continue to weigh on consolidated profit until the effects of the capital investment become apparent. In addition, interest expenses rose from ¥380 million in the previous fiscal year to ¥424 million, making the management of interest-bearing debt an ongoing challenge.

Growth Strategy

Aiming to return to a growth trajectory through three pillars: expansion of the Greater Tokyo business, strengthening of stock-type businesses, and continued inventory and expense management

In February 2026, the company opened its first location in Musashino City, Tokyo (Mitaka Branch), strengthening its land acquisition and sales system for lots for sale in the Greater Tokyo area. Using the Mitaka Branch as a foothold, the company aims to expand sales revenue and profit by increasing the number of units sold and capturing higher-priced properties in the Greater Tokyo area. This is a key driver of the projected sales revenue of ¥58,000 million for FY2027 (ending March 2027).

By adopting seismic damping devices as standard for properties commencing construction from May 2025 onward, introducing the "60-Year Warranty, 60-Year Support System" in November 2025, and renewing the "Smile Club," the company is enhancing the added value of its products and services, aiming to maintain and improve sales unit prices and stabilize its customer base. In Gunma Prefecture, the company is developing a large-scale housing development project, "Central Grand City Shimonoshiro" (50 lots in total).

For the stock business, comprising Used Home Sales (Chuko Jutaku Joho-kan Co., Ltd.) and the renovation business (Grandy Reform Co., Ltd.), the company is promoting expansion of business scale through strengthening its organizational structure. Amid rising demand for used homes against a backdrop of soaring new home prices, the company aims to capture this demand and expand synergies with new home sales.

To curb inventory risk associated with the build-to-forecast production method, the company continues to strengthen inventory management. In FY2026 (ending March 2026), real estate for sale decreased from ¥11,871 million in the previous fiscal year to ¥9,990 million, and selling, general and administrative expenses were also reduced to ¥5,953 million (from ¥6,129 million in the previous fiscal year). This has contributed to an improvement in the operating profit margin to 3.6% (from 2.2% in the previous fiscal year), and the company will continue to maintain this as a foundation for further profitability improvement.
