Big Man on Campus Built on Kolon Engineering and Construction's grounds, the E+ Home is the neighborhood's green building star. From this angle you can see the permeable pavers and sustainable landscaping, like water catchment pools and living walls, that make this place a paragon of green housing.

Roofreader Though they may look like architecture school run amok, the steep pitches and cants of the roof have everything to do with the home’s ecological agenda. By creating a series of green roofs, maximizing daylighting and water catchment, and optimizing the positions of light tubes and building-integrated photovoltaic panels, the roof is a canny mix of passive solar design and state-of-the-art technology.

The E+ Green Home, a concept house located an hour outside Seoul, not only points the way to a greener South Korea, it may well be the most sustainable house in the country. Read more: dwell.com/slideshows/...

Seoul architect Byoung-soo Cho designed the sofas in his urban dream house to resemble building blocks.

Green machines The E+ Home uses 95 different green technologies. Here’s our guide.

Underneath it All By capturing and storing storm water and heat underground, the house saves even more energy.

ArchitekturWerkstatt Vallentin designed this seminar and apartment building in Goesan, South Korea, which is a finalist in the educational buildings category.

Seoul, population 26,100,000. The densely populated South Korean capital is the world's most high-tech megacity, with wireless access available nearly everywhere in the city limits for a small fee.

Where once there was a timeworn 1950s bungalow in the Metropolitan Green Belt south of London, there now stands a dynamic house whose two volumes are joined by a glass atrium. The project was designed by Grant Freeman of OB Architecture.

A third-floor courtyard stands in for a backyard and gives Elodie, the couple’s two-year-old daughter, a place to play outdoors. A Hunting chair by Børge Mogensen shares the space with a child’s chair by Tomii Takashi and a vintage Danish coffee table.

To install Charles Willson’s prefab house, Stillwater Dwellings lifted the structure over an existing barn on the one-acre property. Willson, who is often on the road, wired the house with the latest in smart technology.

Clad in copper panels that Holl had fabricated by the Kansas City, Missouri, company Zahner, the house is daylit by a host of rectangular skylights (inspired by the musical staff) punched through the roofs and the pool’s floor.

The living area opens up to a patio with views of a neighboring vineyard. Paulistano armchairs from Design Within Reach and a Ligne Roset Togo sofa surround a Dunn coffee table from Room & Board. The fireplace is from Montigo.

Architect TaeByoung Yim designed a compact residence in Seoul, Korea, with designated space for studying and entertaining.

Inside the prefab residence, molded plastic Eames chairs from Design Within Reach rest beneath a Splugen Brau pendant light from Flos.

"The design for the Hanwha HQ media facade aims to avoid an overstated impact," says UNStudio founder Ben Van Berkel. "In the evenings, as the mass of the building becomes less apparent, the facade lighting integrates with the night sky, displaying gently shifting constellations of light."

Many of the items in the home come from Mjölk, on the ground floor of Daoust and Baker’s building, which dates to the 1870s and has a distinctive tin facade.

The property includes a rental unit and several outdoor living areas.

Stillwater Dwellings, which has participated in both the 2013 and 2014 Dwell on Design exhibitions, puts a distinct emphasis on natural lighting, efficient floor plans, and high-quality craftsmanship to ensure innovative, modern designs.

Studio Junction transformed a two-story apartment above Mjölk, Juli Daoust and John Baker’s design boutique on Toronto’s busy Dundas Street West, into a tranquil space. A courtyard joins the living room and the open kitchen and dining area.

Japanese and Scandinavian design objects are for sale at the Toronto homewares shop Mjölk, and are also on display in the apartment above it. Here, the store’s owners reside in a two-story space brought to life by Studio Junction. A courtyard spills into the living room and open kitchen and dining area, and translucent shoji-style screens provide privacy. Oak shelves, soap-treated Douglas fir floors, a custom hinoki soaking tub, and a soapstone bowl in place of the kitchen sink are all thoughtful, subtle details.

UNStudio's proposal for the Hanwha headquarters in Seoul features a responsive facade that will be used to control the indoor climate during the day, and come alive as a dynamic light show during the night.

Photovoltaic Cells, of which Hanwha is one of the world’s largest producers, are built into the facade where they can receive optimal energy and harvest the most solar energy possible.

In place of the previous opaque panelling and dark glass, UNStudio will install insulated glass and aluminum framing to increase the amount of natural light and reduce overall energy consumption.
