GigaCrete PlasterMax, an LEED-qualified [5] interior wall coating, is listed as a green building material and interior finish by Architectural Record. [6] [7]
GigaCrete PlasterMax is a fire-resistance rated interior wall coating for insulating concrete forms (ICF), thereby providing a fire-rated green alternative to gypsum drywall over ICF. When applied over an expanded polystyrene (EPS) foam facade of stacked ICF blocks, PlasterMax bonds to the foam and forms a surface that resists abrasion and abuse. PlasterMax can be applied over drywall. [5] [8]
GigaCrete StuccoMax is an exterior water-resistant green stucco product, an inorganic mixture of mineral binders and limestone sand. Like PlasterMax, StuccoMax bonds with expanded polystyrene (EPS) and forms a surface resistant to abrasion and abuse. [2]

In 2009, Next Gen 09 LLC, in partnership with the U.S. Department of Energy Builders Challenge program, built a high-performance 5,200-square-foot (480 m2) ICF demonstration home outside Las Vegas, Nevada. [5] [30] [31] A score of 70 or less on the Energy Smart Home Scale qualifies for the Builders Challenge. [32] The Pittsburgh Post-Gazette , citing GigaCrete PlasterMax as the interior wall finish of the NextGen home, wrote: "[PlasterMax is] a mineral-based hydraulic cement made with recycled waste materials such as fly ash. Sprayed over ordinary drywall and then troweled smooth, it's lighter than conventional concrete and also won't shrink or crack; it's also bullet and blast resistant." [30]
The 2016 ICF Builder Award Winner for Best in Class Small Residential is an ICF home erected in Corte Madera, California. GigaCrete interior and exterior plasters were applied directly over ICF wall surfaces. [33]
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally four years—and qualify by successfully completing that country's competence test in places such as the United Kingdom, the United States, Canada, Switzerland, Australia and South Africa. It is also common that the skill can be learned by gaining work experience other than a formal training program, which may be the case in many places.
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces.
Drywall is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber ; plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption.
Cob, cobb, or clom is a natural building material made from subsoil, water, fibrous organic material, and sometimes lime. The contents of subsoil vary, and if it does not contain the right mixture, it can be modified with sand or clay. Cob is fireproof, termite proof, resistant to seismic activity, and uses low-cost materials, although it is very labour intensive. It can be used to create artistic and sculptural forms, and its use has been revived in recent years by the natural building and sustainability movements.
Wine Country is a region of California, in the northern San Francisco Bay Area, known worldwide as a premier wine-growing region. The region is famed for its wineries, its cuisine, Michelin star restaurants, boutique hotels, luxury resorts, historic architecture, and culture. Viticulture and wine-making have been practiced in the region since the Spanish missionaries from Mission San Francisco Solano established the first vineyards in 1812.
Habitat for Humanity International (HFHI), generally referred to as Habitat for Humanity or Habitat, is a U.S. non-governmental, and tax-exempt 501(C)(3) Christian nonprofit organization which seeks to build affordable housing. It was founded in 1976 by couple Millard and Linda Fuller. The international operational headquarters are located in Americus, Georgia, United States, with the administrative headquarters located in Atlanta. As of 2023, Habitat for Humanity operates in more than 70 countries.
Lustron houses are prefabricated enameled steel houses developed in the post-World War II era United States in response to the shortage of homes for returning G.I.s by Chicago industrialist and inventor Carl Strandlund. Considered low-maintenance and extremely durable, they were expected to attract modern families who might not have the time for, or interest in, repairing and painting conventional wood and plaster houses. Lustron production ceased in 1950 due to the company's inability to pay back the startup loans it had received from the Reconstruction Finance Corporation. Over 2,000 homes were constructed during the Lustron's brief production period, and many remain in use today. Several have been added to the National Register of Historic Places.
Earthbag construction is an inexpensive building method using mostly local soil to create structures which are both strong and can be quickly built.
The concept of home improvement, home renovation or remodeling is the process of renovating, making improvements or making additions to one's home. Home improvement can consist of projects that upgrade an existing home interior, exterior or other improvements to the property. Home improvement projects can be carried out for a number of different reasons; personal preference and comfort, maintenance or repair work, making a home bigger by adding rooms/spaces, as a means of saving energy, or to improve safety.

Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked and filled with concrete. The units lock together somewhat like Lego bricks and create a form for the structural walls or floors of a building. ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted.
Stephen Thomas is an American author, builder and television personality. He was the host of the PBS home renovation series This Old House from 1989 to 2003 and of Renovation Nation, on Discovery's former Planet Green channel, for two seasons (2008–2010) until its cancellation.
Hempcrete or hemplime is biocomposite material, a mixture of hemp hurds (shives) and lime, sand, or pozzolans, which is used as a material for construction and insulation. It is marketed under names like Hempcrete, Canobiote, Canosmose, Isochanvre and IsoHemp. Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints.
Wausau Homes is a custom, new home construction company in the United States.
A chimney breast is a portion of a chimney which projects forward from a wall to accommodate a fireplace. Typically on the ground floor of a structure, the masonry extends upwards, containing a flue which carries smoke out of the building through a chimney stack. Chimney jambs similarly project from the wall, but they do so on either side of the fireplace and serve to support the chimney breast. The interior of a chimney breast is commonly filled with brickwork or concrete.

The Tubbs Fire was a wildfire in Northern California during October 2017. At the time, the Tubbs Fire was the most destructive wildfire in California history, burning parts of Napa, Sonoma, and Lake counties, inflicting its greatest losses in the city of Santa Rosa. Its destructiveness was surpassed only a year later by the Camp Fire of 2018. The Tubbs Fire was one of more than a dozen large fires that broke out in early October 2017, which were simultaneously burning in eight Northern California counties, in what was called the "Northern California firestorm". By the time of its containment on October 31, the fire was estimated to have burned 36,810 acres (149 km2); at least 22 people were believed to have been killed in Sonoma County by the fire.
The Glass Fire was a wildfire in Northern California, that started on September 27, 2020, at 3:48 AM (PDT) from an undetermined cause and was active for 23 days. It was part of the 2020 California Wildfires and the 2020 Western United States wildfire season. The fire was named due to its origin nearby Glass Mountain Road in Deer Park, Napa County, and it extended also into Sonoma County. Initially a single 20-acre brush fire, it rapidly grew and merged with two smaller fires that expanded to 11,000 acres during the night of September 27 into September 28.
