The Fab Tree Hab is a hypothetical ecological home design developed at MIT in the early 2000s by Mitchell Joachim, Javier Arbona and Lara Greden. With the idea of easing the burden humanity places on the environment with conventional housing by growing "living, breathing" tree homes. [2]

It would be built by allowing native trees [3] to grow over a computer-designed (CNC) removable plywood scaffold. [3] Once the plants are interconnected and stable, [1] the plywood would be removed and reused. MIT is experimenting with trees that grow quickly and develop an interwoven root structure that's soft enough to "train" over the scaffold, but then hardens into a more durable structure. The inside walls would be conventional clay and plaster.

An old methodology new to buildings is introduced in this design: pleaching. Pleaching is a method of weaving together tree branches to form living archways, lattices, or screens. [4] The technique is also named "aeroponic culture". The load-bearing part of the structure uses trees that self-graft or inosculate such as live oak, elm and dogwood. [3] The lattice frame for the walls and roof are created with the branches of the trees. Vines create a dense protective layer woven along the exterior, interspersed with soil pockets and growing plants. [3] [1]

This building could be very sustainable as it can use bio-waste for manure for the trees. Which can use the grey water from the home for the trees and garden. There are plans to be able to use rainwater. These building would improve the quality of life by giving back to nature instead of just exploiting it. Throughout the whole life cycle of the home it remains part of the ecology, feeding different organism at different times of its life. The expected life span is greater than standard structures of brick and concrete. The whole community and the individual would befit from this life style. [3]

The Fab Tree Hab is an experiment that would develop over time. Extra operating costs required over the life-time of the home include pest management with organic pesticides and maintenance of the living machine's water treatment system. Technical demonstration and innovation is still needed for certain components, primarily the bioplastic windows that accept growth of the structure and the management of flows across the wall section to assure that the interior remains dry and animal-free. All in all, the elapsed time to reach livability is greater than the traditional sense, but so should be the health and longevity of the home and family. Above all, building this home could be achieved at a minimal price. Depending on the surrounding climate the house is to be grown in, the team expect it will take a minimum of five years to complete its structure. [2] [1] Realization of these homes will begin as an experiment, and it is envisioned that thereafter, the concept of renewal will take on a new architectural form, one of inter-dependency between nature and people.

As of May 2007 Mitchell Joachim stated that there is a "50 per cent" organic project in California, combining natural elements and traditional construction. [2]

Trees

Main trees suggested to be used are elms, dogwood and oaks. [3] The teams hopes the homes can be grown using mainly native trees. [1]

Environmental design is the process of addressing surrounding environmental parameters when devising plans, programs, policies, buildings, or products. It seeks to create spaces that will enhance the natural, social, cultural and physical environment of particular areas. Classical prudent design may have always considered environmental factors; however, the environmental movement beginning in the 1940s has made the concept more explicit.

A tree house, tree fort or treeshed, is a platform or building constructed around, next to or among the trunk or branches of one or more mature trees while above ground level. Tree houses can be used for recreation, work space, habitation, a hangout space and observation. People occasionally connect ladders or staircases to get up to the platforms.

<span class="mw-page-title-main">Green building</span> Structures and processes of building structures that are more environmentally responsible

Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’

Underground living refers to living below the ground's surface, whether in natural or manmade caves or structures. Underground dwellings are an alternative to above-ground dwellings for some home seekers, including those who are looking to minimize impact on the environment. Factories and office buildings can benefit from underground facilities for many of the same reasons as underground dwellings such as noise abatement, energy use, and security.

Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings through improved efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment.

<span class="mw-page-title-main">Tree shaping</span> Use of living trees to create structures and art

Tree shaping uses living trees and other woody plants as the medium to create structures and art. There are a few different methods used by the various artists to shape their trees, which share a common heritage with other artistic horticultural and agricultural practices, such as pleaching, bonsai, espalier, and topiary, and employing some similar techniques. Most artists use grafting to deliberately induce the inosculation of living trunks, branches, and roots, into artistic designs or functional structures.

<span class="mw-page-title-main">Sustainable city</span> City designed with consideration for social, economic, environmental impact

A sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact, and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus will also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.

Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle.

Pleaching or plashing is a technique of interweaving living and dead branches through a hedge creating a fence, hedge or lattices. Trees are planted in lines, and the branches are woven together to strengthen and fill any weak spots until the hedge thickens. Branches in close contact may grow together, due to a natural phenomenon called inosculation, a natural graft. Pleach also means weaving of thin, whippy stems of trees to form a basketry effect.

Environmentally sustainable design is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce the consumption of non-renewable resources, minimize waste, and create healthy, productive environments.

<span class="mw-page-title-main">Green home</span>

A green home is a type of house designed to be environmentally sustainable. Green homes focus on the efficient use of "energy, water, and building materials". A green home may use sustainably sourced, environmentally friendly, and/or recycled building materials. This includes materials like reclaimed wood, recycled metal, and low VOC paints. Additionally, green homes often prioritize energy efficiency by incorporating features, such as high-performance insulation, energy-efficient appliances, and smart home technologies that monitor and optimize energy usage. Water conservation is another important aspect, with green homes often featuring water-saving fixtures, rainwater harvesting systems, and grey water recycling systems to reduce water waste. It may include sustainable energy sources such as solar or geothermal, and be sited to take maximum advantage of natural features such as sunlight and tree cover to improve energy efficiency.

Terreform ONE is a 501c3 non-profit architecture and urban think tank that advances ecological design in derelict municipal areas. By formulating unsolicited feasibility studies and egalitarian designs, their mission is to illustrate speculative environmental plans for New York City and other cities worldwide. Their intention is to support community outreach and master plan solutions in underprivileged areas that do not have direct access to qualified architects and urban designers.

Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or requirements". Refurbishment can be done to a part of a building, an entire building, or a campus. Sustainable refurbishment takes this a step further to modify the existing building to perform better in terms of its environmental impact and its occupants' environment.

Living root bridges are a kind of tree shaping in which rivers are spanned by architecture formed out of the roots of ficus plants. Due to their being made from living, growing, trees, they "show a very wide variety of structural typologies, with various aspects of particular bridges resembling characteristics of suspension bridges, cable-stayed bridges, arches, trusses, and simply-supported beams." They are common in the Indian state of Meghalaya.

<span class="mw-page-title-main">Baubotanik</span> Building term

Baubotanik is a building method in which architectural structures are created through the interaction of technical joints and plant growth. The term entails the practice of designing and building living structures using living plants. In this regard, living and non-living elements are intertwined in such a way that they grow together into plant-technical composite structures.

There are various methods of tree shaping. There are strengths and weaknesses to each method as well commendable tree species for each process. Some of these processes are still experimental, whereas others are still in the research stage. These methods use a variety of horticultural and arboricultural techniques to achieve an intended design. Chairs, tables, living spaces and art may be shaped from growing trees. Some techniques used are unique to a particular practice, whereas other techniques are common to all, though the implementation may be for different reasons. These methods usually start with an idea of the intended outcome. Some practitioners start with detailed drawings or designs. Other artists start with what the tree already has. Each method has various levels of involvement from the tree shaper.
