The teepee will always fascinate from its lore, tribal romance, and having the habitable efficiency of a portable umbrella. It has grown in popularity, designed in trendy fabrics as a decorative novelty for children to retreat and reboot. On a grander scale tepees are associated with Ralph Lauren’s Telluride and shelter on glamping trips.

Teepees are more than just novelties but unique, eco-efficient homes.

While commonly associated with American Indians, teepees have also populated parts of Europe and Asia. The structure not only has benefits for a nomadic existence but in the current day they are eco-friendly.

The “pointy-hat” cantilevers are erected slightly above ground, which prevents insects, humidity and fallen snow from entering the house.

In this home in Nasu, Tochigi, a resort area in Japan, the homeowners are a young couple who enjoy an environmentally-aware existence with organic gardening and limiting their carbon footprint in this natural environs. They enlisted architect Hiroshi Nakamura &NAP with the task of preserving the surrounding woods where they plotted the home. “We avoided large-scale construction to build the rooms on the few remaining flat surfaces of the sloping ground, as if sewing them together,” says Nakamura.

The high ceiling allows the structure to receive direct sunlight, which is especially needed in the dense woods. To offset the expense of air-conditioning they eliminated unnecessary space.

The teepee’s form matches the neighboring tree branches.

Nakamura’s design process:

+ They began by cutting down the upper space diagonally to make the ceiling lower based on the way people move.

+ The new form matches the tree branches that spread out radially. This resulted in a tent-shaped house with only one-third of the volumes. Although the highest ceiling is 26 feet, the average ceiling height is 16 feet. Dwellers cannot stand upright close to the walls, so Nakamura simply turned the spaces into sleeping and sitting areas. The ceiling descends like a tent and enables the creation of a warm living space that mingles with the trees. “You will feel the warmhearted embrace of the house around you,” he says.

+ Other eco-conscious design tricks include the “pointy-hat” building cantilevers, which are slightly above ground in order to prevent insects, humidity and fallen snow from entering the house.

+ The windows are all double glazed in order to ensure that the tall spaces are airtight and well insulated. The fireplace and the air-conditioning underfloor capitalize on the floor heating and pit.

+ During summer, warm air gathers at the top and escapes through the upper window. In winter, warm air at the upper part will be drawn in and blown out at floor level, creating a comfortable air flow.

A constant surprise with light and, in this instance, sheds an intriguing profile.

The design fosters family gatherings and connecting naturally. “It is similar to primitive spaces seen in the houses of the Jomon People (Ancient Japanese) and Native Americans. The structure of the house initiated a lifestyle with close interaction, because the family sat along the low wall facing each other. A fire, a light or a table was set in the middle to initiate conversation as the family gathered around the center. The architecture has had an influence on people’s habits and it strengthened the connection and bond of the family,” Nakamura says.

Built in tables detailed with wooden poles capture the outdoors into indoors theme.

“Design touches include light wood, natural tones and artisanal additions like the pressed flower glass door. “Akebi, viola, anemone, geranium, larkspur – the wild flowers found in the pressed flower glass all came from the surrounding woods,” says Nakamura. “Our idea was to find a new way to reflect the blessings of nature, not just in the context of samples or picture books. We manufactured the glass by sandwiching the pressed flowers in resin films between two thick glasses and firing them in vacuum.”

Flower cuttings from the surrounding area are immortalized within indoor glass windows.

Pressed flowers sealed between two panes of glass protect the flowers from decolorization.

An almost space age feel happens at night.

The home takes on a new direction once night falls. Moonlight naturally illuminates the exterior, wild animals circulate freely around the home, which has a presence that is as natural as its neighboring trees. “In the darkness of the night, you will find a house filled with warm and gentle looks,” Nakamura says. It’s like living on a camp ground with all the efficiencies.

There is an alluring quality from the lit teepee, like a jack-o-lantern at night.
