Four houses currently shortlisted for RIBA House of the Year 2015

RIBA has already revealed the first four houses shortlisted for the recently renamed House of the Year award. Formerly called the Manser Medal, the House of the Year award still carries the same purpose of distinguishing the year's most innovative house designed by a UK-based architect.

Since November 4, RIBA and Britain's Channel 4 have featured the shortlisted homes in a weekly TV series called "Grand Designs: RIBA House of the Year". Three more houses are scheduled to be featured before the winning project is broadcast on TV next Wednesday, November 25.

Check out the shortlisted projects below.

Flint House, Buckinghamshire
by Skene Catling De La Pena

bioMason: "Approximately 85% of global construction uses masonry; over 1.23 trillion clay bricks are manufactured every year, and cement manufacture is among the most carbon and polluting of industries. As an alternative to traditional clay brick manufacturing, which is responsible for approximately 800-million tons of global CO2 emissions every year and many deaths globally from air pollution, bioMason 'grows' durable bricks comparable in strength to calcite-cemented sandstone by using biomass, aggregate, nutrients, minerals, and bacteria to produce a natural bio-cement in less than three days in ambient temperatures, a process similar to how corals form through bio-mineralization/calcium carbonate fixation. The nutrients and minerals required are globally abundant renewable resources but may be also extracted from industrial waste streams, contributing to remediation efforts and making this mode of brick production even more ecologically beneficial. This highly promising project is an inspiring exemplar of a biomimetic strategy that finds non-polluting, benign solutions to human needs by emulating natural processes."

Casa Pueblo de Adjuntas: Forest School: "The Forest School is an outgrowth of Casa Pueblo, a grassroots citizens’ movement that emerged 35 years ago in Puerto Rico to prevent open-pit mining in the island’s central mountain region. After 15 years of struggle Casa Pueblo succeeded in preventing what would have been irreversible damage to the core of the island’s ecological health and a cascade of destructive socio-economic effects, and helped create Puerto Rico’s first state forest, protecting watersheds and 19 separate landholdings linked by biological corridors, which became Puerto Rico’s National Model Forest, an inspiring model for the global community. Casa Pueblo evolved into a vibrant community organization, one of the key anchors of Puerto Rico’s environmental movement. It founded The Forest School, an institution in the heart of the National Forest, whose curriculum includes agro-ecology and biodiversity, climate change, water and renewable energy, and community development. The Forest School is a uniquely inspiring model—an educational institution that grew out of a grassroots people’s movement to guarantee that future generations would manage the commons sustainably, in perpetuity."

Community Architects Network: "The Community Architects Network (CAN) is a coalition of architects, planners, builders, engineers, lecturers and volunteers active in participatory design, planning, and development across 19 countries in Asia, united by their conviction to “let the people be the solution”, and using the design process as a vehicle to create the conditions for positive social and ecological transformation. CAN has created a facilitation network, sharing expertise in order to empower grassroots efforts, rather than deploying expert professionals with outside visions. Through handbooks, action-based workshops, and community architecture trainings, CAN offers a platform of exchange to engage governments, local authorities, universities, and professionals in people-driven processes."

Sandele Eco-Retreat and Learning Centre: "Sandele Eco-Retreat and Leaning Centre is a unique eco-tourism project in the politically and logistically challenging environment of South Gambia in West Africa. It is exemplary not only in its passionate dedication to regeneration, sustainability, wildlife protection, renewable energy, the use of natural building materials, and local citizens' education and personal development, but in its unusual commitment to transferring ownership to the local people: in 19 years, total ownership of Sandele Eco-Retreat will be gifted to the community. Meanwhile, a payment toward community development is made from every bed night sold, and the management works very closely with the local population, providing employment and offering technical expertise to help neighboring villages develop resilient infrastructure. Sandele is also raising standards of living through its spin-off construction company, which builds sustainable, attractive low-cost housing."

"The house sits within the grounds of a wider estate and forms accommodation for visitors who include family members as well as artists. The building is split into two parts: the main house plus an annexe. The building is constructed of masonry with flint cladding. The project is a rare example of a poetic narrative whose realisation remains true to the original concept. The site is on a seam of flint geology and is surrounded by ploughed fields where the flint sits on the surface. The building is conceived as a piece of that geology thrusting up through the flat landscape. The innovation and beauty of the scheme is particularly evident in the detail of the cladding that starts at the base as knapped flint and slowly changes in construction and texture until it becomes chalk blocks at the highest point. This gives both a feeling of varying geological strata with the building dissolving as it reaches to the sky. The architects worked with a number of specialist and skilled craftsmen to achieve the end result. The development is part of a wider artistic project that has involved engagement with artists, photographers and musicians."

Drylands Resilience Initiative and HAZEL: "The Drylands Resilience Initiative is a collaborative, multi-year project working with a number of research partners to create a water-smart future for Los Angeles through the development of Hazel, a first-of-its-kind computational engine that will permit both granular and holistic analyses of overland surface and groundwater flows in the context of the built and natural environments. Founded on the belief that 'design has an unrecognized potential to fuse science and policy, catalyzing public imagination in the face of climate challenges', DRI is working to make Hazel a tool that will support coordinated, whole-systems thinking and decision-making at regional levels; shape water-smart urban planning, zoning and building policy; build a water-conversant citizenry; transform design education; and guide societies to make the most appropriate, sustainable water choices."

GreenWave: "GreenWave offers a radical new form of aquaculture: multi-species 3D ocean farming. Instead of growing vulnerable monocultures, GreenWave uses a system of floating ropes on which seaweed, scallops and mussels thrive, below which lie stacked oyster and clam cages. This approach creates a vibrant, low-cost, high-yield, zero-input system that can produce very large quantities of sea vegetables and shellfish per acre per year. The system is not only non-polluting but actually restores aquatic ecosystems by filtering and cleaning millions of gallons of seawater, sequestering nitrogen and carbon, and providing habitat for many wild marine and bird species. GreenWave's crops can be sources of food, fertilizers, animal feeds, pharmaceuticals, cosmetics, bio-fuels and much more."

Mahila Housing SEWA Trust: Climate Resiliency Initiative: "This new project of the SEWA trust, an India-based NGO with a track record working for “dignified homes, dignified work, and dignified lives for women working in the informal economy” since 1994, is an effort to develop new models that will help poor urban dwellers in South Asia build resilience to the rising challenges of climate change—including increasing heat waves, flooding, water shortages, and vector borne diseases. Their pilot program is in Ahmedabad, a city vulnerable to climate impacts, and initiatives in four other Indian cities as well as in Katmandu and Dhaka are slated to follow. The SEWA team is skilled at engaging regional and municipal governments, scientific experts, and engineers in developing strategies while simultaneously nurturing democratic, grassroots decision-making among the urban poor themselves, and training women to collect and interpret scientific data. The climate resiliency project involves risk assessment and mapping on precipitation, temperature impacts, water flows, and health trends, and the subsequent deployment of the most appropriate technologies including solar-powered ventilation and electricity generation and water harvesting and storage."

Omega Global Initiative: "OMEGA, which began as a NASA biofuels research project to meet the demand for liquid fuel without using land, freshwater, or fertilizer, evolved into a broad-reaching plan for a 'system of systems' to integrate algal biofuels production with water recycling, solar energy production, and compatible aquaculture, among many other components. This year the non-profit OGI was formed by one of the lead research scientists of the original Omega initiative to provide a detailed “roadmap” for the implementation of the Omega vision in coastal communities, transforming wastewater into a resource that produces algal biomass and potable water, expands local food production, increases the use of solar power, and supports local economies through jobs and new sources of revenue. OGI is currently seeking to establish small-scale demonstration projects in diverse locations to adapt and evolve the technology, with the primary goal to pave the way for large-scale future uptake."

The Nubian Vault Programme: A Roof, A Skill, A Market: "This project has a highly successful 15-year track record of building low cost, high quality, healthy, culturally and climatically appropriate dwellings and buildings throughout the physically and politically challenging Sahel region of Africa. They resurrected an ancient Nubian vault structure that they have systematized, adapted and are spreading throughout a vast, ever growing swath of Africa in hundreds of villages, and now urban areas as well. This technique uses low-cost or free durable, sustainable, local, natural materials: no imported, expensive corrugated iron sheets, sawn timber or concrete, whose costs exacerbate poverty and provide unhealthy living conditions. The project team has created a large and quickly growing pool of local masons who learn as they work and then pass on their skills, a viral economic cascade of benefits to communities. Their strategy is integrated into local economic circuits, relies on locally sourced materials, and is creating autonomous, sustainable markets, addressing housing shortages, and building profits at the “bottom of the pyramid” by generating thousands of skilled local entrepreneurs."

One People One Reef: "One-People-One-Reef is a collaboration between a multidisciplinary science team and Pacific-island communities in the outer islands of Micronesia, working together to integrate traditional knowledge and conservation practices with modern science in order to find comprehensive solutions to declining fisheries and degraded reefs. Rising sea levels threaten coastal areas worldwide, and tropical low-lying islands are at particular risk, as poor fishing practices, inadequate waste handling, rising fuel costs, and declining food security compound already dire challenges. The human population and land surface of the Yap islands are small, but the area of ocean they autonomously govern and manage is vast. These island communities represent some of the last remaining, intact island cultures, and they are at a tipping point—still comparatively healthy, but poised at the brink of accelerating decline...The One People One Reef scientific team collaborates with fishermen, community leaders, elders, and youth to understand the patterns of ecological and cultural decline and to develop management and conservation plans (and local teams to monitor them)."

"This four bedroom family house is formed of two prefabricated weathering steel volumes inserted behind a retained nineteenth century stable wall. The layout is informal; rich with incidental spaces and unexpected light sources. A delicate, glazed circulation link reveals the contrast between a rustic exterior and refined interior. Split into two wings, the simple plan makes the most of a constrained site and responds to the living patterns of the young family. Completed in January 2014, Kew House was an experimental project, driven by the architect’s and clients’ shared interest in a ‘kit-of-parts’ approach, prefabrication, and the self-build possibilities emerging from digital fabrication."

Warka Water 3.2: "Developed by Architecture and Vision Studio with the support of the Italian Cultural Center in Addis Ababa and the Ethiopian government, Warka Water is a 33-foot-tall, robust but very lightweight modular tower made from locally available bamboo and natural fiber ropes. The structure harvests water from the ambient air in dew and fog to supply clean water to rural communities in poor regions where potable water sources are rare. The construction techniques, inspired by Ethiopian vernacular architecture and traditional basket weaving, use local labor and available materials in an elegant combination with a unique fabric and polyethylene textile moisture-collection mesh. The triangulated grid shell is inspired by Buckminster Fuller’s geodesic dome. A Warka Water tower can collect up to 100 liters of drinking water per day. The technology is biomimetic, conceived by observing nature’s strategies to harvest moisture from the air in a creature such as the Namib beetle, or on a spider web, or by such plants as lotus flowers and cacti. Demonstration towers have already been built and displayed, and the first onsite prototype is being deployed this year in a mountainous region of Ethiopia, a nation with among the worst water availability and quality in the world, resulting in high disease rates and stymied development. This is a stellar example of an elegant, simple, low-cost but life-saving (and life-giving) artifact designed by honoring nature’s design sophistication and adapting it to solve human problems effectively, harmlessly, and gracefully."

Project Drawdown: "Project Drawdown is a visionary initiative comprised of 200+ individuals and institutions from across the globe, specializing in a wide range of disciplines, but all working in a coalition to research and analyze 100+ “state-of-the-state” climate solutions, whose uptake would ensure that humanity could actually draw down the excessive CO2 and other greenhouse gases already in the atmosphere. The Drawdown research seeks to reframe the issue by insightfully and elegantly quantifying and articulating the beneficial financial, ecological and social impacts that each technology could deliver over the next thirty years. The results will be conveyed through an internationally released book (40 countries in 12+ languages) and an interactive platform and companion open-source database (to which new data and research can be added and adapted to each locality and target audience, from CEOs to schoolchildren), both slated to be available before the UN Climate Talks in Paris in December 2015. The database and platform will allow users anywhere to interact directly with the data; adapt the models and projections to customized local climate strategies; and create meaningful measurement methods and policy tools."

"This stand-alone contemporary villa set in the Sussex countryside is an exceptional retreat. Externally the house is quietly confident, with its row of low-profile roof pyramids, windows positioned to take advantage of the views and a muted colour palette of materials. A lack of decoration and ornament gives this modern house a functional feel, but one that is cleverly considered to the very last detail. Internally the double-height void and staircase orchestrate the house, effortlessly, organising a contiguous open plan and cellular spaces into a simple but elegant arrangement. The over-sailing first floor produces the feeling of a quiet monastic cloister with sun-filled spaces and carefully framed views. There is much to admire about the project, and it is clear the designers have invested a lot of energy into guiding the project to have a crafted feel through modern materials and technologies. The design fulfils the brief and provides the clients with so much more."

Vaulted House, London
by vPPR Architects

"This family house, built on the walled site of a former taxi garage, is almost entirely hidden in the middle of a Victorian block in Chiswick. The approach is via a covered passage, beyond which is a brick-lined front porch. A recessed, chamfered surround for the front door hints at the geometric language of the house’s primary formal and spatial idea: a walled enclosure above which a cluster of six conjoined hipped roofs hovers enigmatically. 

The house is arranged so that on entry, one is poised between the two levels, with stairs leading up to the open-plan living level, and down to the lower level of bedrooms. The six roofs, each topped by a skylight, are lifted above the enclosing boundary wall. This creates a sense of weightlessness and a borrowed panorama of neighbouring gardens. The hipped roofs’ sloped planes join precisely to form a series of large coffers or ‘vaults’. These vaults spatially define and individually illuminate various parts of the open plan main living space; kitchen, dining and living areas. In two places, the vaulted roofs are absent, leaving two storey deep voids that act as garden courtyards for the basement level bedrooms and children’s playroom. Glazed walls slide back to expand the living space onto balconies that project into the voids, formed with perforated mesh. This material and its careful detailing creates beautiful shadows on pristine courtyard walls."
