Plannedore Higashiogu 6: A Newly Built, Energy-Efficient Home in Tokyo
This exclusive new-build detached house, known as Plannedore Higashiogu 6, is a single-unit sale offering full ownership rights. The property features a bright 12.5-tatami mat living-dining area. As a ZEH (Net Zero Energy House) standard residence with an Energy Saving Grade 6 rating, it boasts high airtightness and insulation. This design ensures comfortable living with minimal electricity costs, keeping you warm in winter and cool in summer.
The property is constructed using the developer's proprietary "Plus One" construction method, which is earthquake-resistant. The company handles everything from design and construction to sales in-house, selling new subdivision homes directly to customers. This integrated approach means no real estate brokerage cooperation is required, and no intermediary fees are necessary. The developer, Hasebe, is a housing manufacturer celebrating over 78 years in business and has extensive experience with subdivision homes in Tokyo's northern wards (Arakawa, Taito, Bunkyo, Kita).
A key selling point is the earthquake-resistant Plus One construction method (patented). All processes, from wood pre-cutting at their own factory in Tsukuba, Ibaraki, to construction, design, and real estate sales, are handled in-house, eliminating intermediary fees. Post-delivery after-sales maintenance and future renovations are also assured due to their own construction. With over 80 years of trust and a proven track record, Hasebe uses accumulated know-how and a diverse network to support customers from a specialist perspective in real estate and construction.
After-sales service and maintenance are a priority. After moving in, the company sends a reply-paid postcard and confirms schedules by phone to conduct three free periodic inspections: at 3 months, 1 year, and 2 years after delivery. The structural framework and parts preventing rain leakage come with a 10-year warranty, and a 10-year ground warranty against uneven settlement is standard. The company views the home purchase as the beginning of a long-term relationship.
The Plus One construction method is a uniquely developed wooden three-story system. It is based on traditional post-and-beam framing but features panelized floors, walls, and roofs. This combines the design freedom of post-and-beam construction with specially made seismic panels, allowing for spacious living areas even on narrow plots while achieving high earthquake resistance. The home has achieved the highest seismic grade of 3, meaning it is 1.5 times stronger than the minimum required by building standards, qualifying for a 50% discount on earthquake insurance.
Regarding energy efficiency, a highly insulated home can maintain a comfortable temperature with minimal heating. According to Ministry of Land, Infrastructure, Transport and Tourism estimates, compared to a house built before 1980, this can reduce annual utility costs by 70,000 yen. Increasing a home's insulation and reducing heating/cooling use also reduces CO2 emissions. High-precision panels improve airtightness and insulation, eliminating indoor temperature differences for a comfortable environment and helping prevent heat shock.
The property includes a spacious approximately 13-tatami mat rooftop balcony, perfect for gardening or placing a table and chairs. The east-facing orientation welcomes morning sun. Other features include a keyless electric lock on the entrance door, an integrated camera intercom, mailbox, and delivery box. The kitchen is equipped with a touchless faucet. The bathroom features a TOTO system bath with a 160cm long tub and a drying function. One parking space for a light vehicle is available.
