Eco First Park serves as a new kind of "school"
where everyone can participate in thinking about how we live and the environment.

Our "Environmental Future Plan" was announced in 1999 ahead of the rest of the industry.
Since that time, Sekisui House has aimed to create a housing environment that is friendly to both humans and the planet and can be passed down from generation to generation.

These efforts were highly evaluated by the Ministry of the Environment, and in 2008 we were certified as a "Eco-First Company" —the first in the housing industry.

Sekisui House has accumulated a record of environmental activity, Eco First Park is a facility that symbolizes this record and crystalizes these activities.

Eco First Park brings together the developed wisdom of those who have gone before us in a facility full of the latest in eco-friendly design and technology.

Here you can experience, learn about and study various ways of living, and will be sure to encounter the styles of living that will meet the demands of the future.

This space controls light and wind, and in winter receives ample sunlight to reduce heating costs. In summer, natural breezes enter to provide comfort without wholly relying on air conditioning.

South side exterior

The inner veranda leverages the positive aspects of traditional Japanese homes, but with a near-future look to it-a result of our quest for the ideal in sustainable city living.

Comfort of being connected to nature

The natural elements in the courtyard and inside the house come together to create a comfortable space. Emphasis has been placed not only on appearance but also to how it feels to the touch and underfoot in order to create an abundant space that appeals to the five senses.

Comfort of being connected to people

The HEMS-linked TV in the living room makes possible ready access to lifestyle information, disaster prevention information, and more.

Comfort of being connected to housing

A clean, quiet electric vehicle is the start of a new relationship between housing and cars. We also propose systems for comfortable living, and that extend the life of housing, such as a home history system that stores housing maintenance information and a control system of three linked batteries.

Planting five trees native to Japan: three for birds and two for butterflies. - Living with nature, modeled on the hometown ("satoyama") landscape.

"Gohon no Ki" landscaping concept to enrich lives
Trees rooted in the region bestow blessings on people's lives and at the same time provide birds, insects and other living things with food and a place to live. Needless to say, they contribute to the ecosystems of the area, but they also bring about healthy living with a sense of the seasons.

Shores of life that nurture living things

The pond and flow of water nurture many living things, providing a habitat for fish, a bathing place for birds, a place for fireflies to lay eggs and other such benefits. Rainwater flows into the pond, and naturally purifies.

Resource Wellspring Resource Recycling Center
Promote Resource Recycling

100% of building waste is recycled for house construction without wastage.

Waste is separated into 27 categories at new construction sites
When separating the waste, IC tags are attached. Special tag readers are used, and wirelessly connected instruments measure the weight for more accurate tracking of the amount of waste generated. We have established excellent traceability.

Waste is further separated into 80 categories at the "Resource Recycling Center“
Waste collected from the construction site is further separated into 80 categories, and 100% of it is recycled either in-house or by a contractor. We are also engaged in development of our own recycled products such as "Platama Powder" field marker for which we have acquired the Eco Mark.
