Prefab Design: 9 Cutting-Edge Modular Homes

Custom-built prefabricated homes, such as the modernist perrinepod, encourage the green value that houses should be nothing more or less than their inhabitants need. By using less space and materials, prefab homes preserve natural resources, while leaving the smallest of footprints. They are usually manufactured in a way that leaves a smaller ecological footprint than conventional on-site construction.

Hoping to 'keep the world beautiful now and for generations to come,' M Finity takes an eco approach to all of their unique modular products. From houses, cabanas and sheds, M Finity employs sustainable, recycled, low-energy materials and fixtures to create functional, space-efficient design. (See more green sheds.)

The eye-catching, quirky Vail Grant House from Pugh + Scarpa Architects is constructed from prefabricated structural concrete insulating panels (SCIPS) made by Green Sandwich Technologies. All panels are 60% recycled material, including wire mesh made from recycled auto parts and fly ash, a byproduct of coal burning.

The Vail Grant House contains several elements that maximize energy performance. SCIPs (structural concrete insulating panels), for instance, create an average insulation value of R-40, while solar panels produce enough energy to power the entire house. Air conditioning is supplied naturally by pipes that draw cool air from the hillside. In colder weather, large windows allow the sun to heat interior concrete slabs, creating natural convection currents.

The M Finity Micro Cabana is prefabricated with a working bathroom. The diminutive space is perfect for use as a pool house or backyard guest room.

With increased energy efficiency, green building can provide truly affordable housing, lowering energy bills by 40%. After the destruction of Hurricane Katrina, architects Andrew Kotchen and Matthew Berman of Workshop/apd designed this sustainable model for New Orleans' devastated Ninth Ward.

Designed by architect Ray Kappe and installed in a jaw-dropping eight hours, the First LivingHome was recently certified LEED Platinum by the United States Green Building Council, the first home in the nation to achieve this ultra-green distinction.

Los Angeles architects target="_new">Marmol Radziner have recently launched a line of innovative modular prefabs that are making waves. Their Desert House Prototype employs four house modules and six deck modules, a quantity chosen to suit the wide desert landscape. Sweeping views abound.

Marmol Radziner's Desert House Prototype uses solar power to supply energy, while the thermal mass of the home's concrete floor is great for retaining heat. The steel frame is recyclable.
