Against the backdrop of rising housing prices, demand for rental housing for families with children is increasing. The new "Basic Act on Housing" approved by the Cabinet in March indicates a policy to promote the supply of high-quality rental housing that accommodates diverse lifestyles, enabling families with children and others to achieve their desired lifestyle without undue burden. Meanwhile, with the risk of soaring energy prices due to recent global circumstances, demand for homes with high energy-saving performance and energy self-sufficiency is expected to further increase.
The "HEIM MAISON-GX" launched this time is a rental housing package that is standard compliant with the government-promoted "GX-oriented housing" (※1) while also considering affordability (the ability for residents to pay without undue burden). By utilizing the excellent cost performance of modular housing and the benefit of reduced utility costs through solar power generation systems (hereinafter referred to as PV), it achieves both the reduction of residents' actual burden and the owners' benefit of stable rental management. Furthermore, it provides security features that address current crime prevention needs and IoT-based equipment control (※3, 4), offering homes where families with children can live safely and comfortably.
Sales will commence in conjunction with the start of applications for the Future Eco Housing 2026 Project (rental housing) on May 13, contributing to the realization of a decarbonized society through the provision of high-quality housing.
Features of "HEIM MAISON-GX"
1. Rental housing package that is standard compliant with "GX-oriented housing" (※1)
2. Balances benefits for both residents and owners through reduced monthly housing costs and added value
3. Equipped with an IoT system that provides crime prevention, energy visualization, and convenience useful for families with children
■ Features of "HEIM MAISON-GX"
1. Rental housing package that is standard compliant with "GX-oriented housing" (※1)
This product is based on a high-airtightness and high-insulation structural frame achieved with excellent construction precision, as most of the house building is done in the factory. It complies with insulation grade 6 (※5) through aesthetically pleasing triple-glazed aluminum-resin composite sashes and foundation insulation specifications.
Furthermore, by adopting energy-efficient equipment such as highly efficient water heaters and air conditioners, it achieves a primary energy reduction rate of 35% or more (※6) excluding renewable energy. In conjunction with advanced energy management by our unique HEMS "Smart Heim Navi" that smartly manages energy, and the introduction of PV, it is standard compliant with the performance requirements for GX-oriented housing (※1).
Additionally, storage batteries can be installed. By combining PV and storage batteries, electricity generated during the day can be efficiently self-consumed, and surplus power can be stored in the storage battery. In the event of a disaster, it becomes possible to use electricity safely not only during the day but also at night (※7), demonstrating high resilience against power outages caused by disasters.
It is a home that contributes to reducing environmental impact while enabling residents to live comfortably without excessive burden.

2. Balances benefits for both residents and owners through reduced monthly housing costs and added value
This product leverages the rationality and efficiency of modular housing, where most of the construction is done in the factory, to demonstrate high cost performance. It also suppresses procurement costs through centralized purchasing and streamlined distribution. Furthermore, subsidies for GX-oriented housing under the Future Eco Housing 2026 Project (※1) can be utilized.
Additionally, this product adopts a "resident還元スタイル" (resident benefit return style) that directly returns the utility cost benefits from PV sales to residents. Comparing this product, equipped with PV 2.0kW and HEMS, with a typical rental housing not equipped with these facilities, based on a 2LDK floor plan intended for families with children, an average annual utility cost reduction of approximately 67,000 yen (※9) is expected over 15 years. By reducing the daily electricity bill burden, it leads to an overall reduction in housing costs including rent and utilities, allowing residents to live in high-quality housing without undue burden.
Moreover, owners can realize stable rental management and secure long-term returns by controlling construction costs and adding high value, such as installing equipment highly desired by residents, thereby increasing occupancy rates.
By providing "affordable rental housing" that considers initial investment and running costs and is reasonable for both residents and owners, we will contribute to solving societal issues.
