Hill House – Andrew Maynard Architects
Design is complex. There is little that is more complex to design than a home, however fundamental issues offer an architect a starting point; where is the sun? How do we capture it in winter, how do we exclude it in summer?
The thin allotments that dominate Melbourne’s northern suburbs often provide indomitable constraints to solar access and therefore require the production of unorthodox ideas to overcome these constraints and convert them into opportunities.
The site faces north therefore relegating the backyard, the family’s primary outdoor space, to shadow throughout the year. In the 90s a two storey extension was added reducing solar access even further while creating deep dark space within the house. A family of five wished to create a long-term home, which could meet the requirements of three small children and their slow transformation into young adults over the years.
Rather than repeating past mistakes and extending from the rear in a new configuration, the proposal was to build a new structure on the rear boundary, the southern edge of the block, upon the footprint of what had been, until now, the back yard. The new structure faces the sun, the pure cantilevered box above acts as the passive solar eave, cutting out summer sun, while letting winter sun flood in.
Following the decision to build at the rear of the block a ubiquitous modern box was first imagined. Soon it seemed necessary to pursue the opportunity to activate this new, once shaded, now sunny facade. A seat along the new northern facade? Perhaps a series of steps like the Scalinata della Trinità dei Monti? But how does one lounge in the sun on steps. Perhaps a slope instead …. And the hill house evolved/emerged.
The new structure faces the original house. The backyard is now the centre of the house activated by the built form around it. Beyond solar gain, the benefit of the new structure being in the backyard is that it borrows landscaping from its neighbours’ gardens. The high windows about the entertainment cabinetry and the dining area are enveloped in trees. Internally one gets the sense that Hill House is enveloped by bush rather than part of the suburban mix.
Along one boundary a 2m high fence was created, but unlike most houses the Hill House has a one metre wide fence; a corridor lowered into the site to achieve head height. This in turn creates a lowered dining area. One rises into the living space. The change in floor level creates a bench seat for the Maynard designed ZERO WASTE TABLE.
Front Street no longer provides the main entry to the home. Family now enters via the side lane. The original house, now private dormitory spaces, no longer has a typical relationship to the N#@$%k street’s “front” door. The original house, as with most narrow blocks throughout Melbourne, demanded that visitors walked a long corridor past bedrooms to the living area. Stolen quick glances into dark private spaces always occurred along the journey. At the Hill House the entry is reorientated. The kitchen, the nerve centre, the hub of the house, is the new greeting point. Beyond is the park. Adjacent is the living space, the yard and the “kids’ house” beyond.
The old house is converted into “the kids’ house”. The old house is as it once was. The rear of the simple masonry structure, though spatially connected, is not reoriented, a face is deliberately not applied. It is left honest and robust. With a restrained piece of “street art” to be applied.
Andrew Maynard Architects was established in 2002 following Andrew’s receipt of the grand prize in the Asia Pacific Design Awards for his Design Pod. The core principles in the establishment of AMA was a balance between built projects and broad polemical design studies. This is demonstrated in AMA’s highly crafted built work and socio-politically based concepts both of which have been widely published and have garnered global recognition.
Andrew Maynard Architects explores architecture of enthusiasm – AMA treats each project as a unique challenge, offering unique possibilities and prides itself in experimentation. All of AMA’s designs are concept rich, left of centre and sustainability conscious; styles and singular themes are avoided. AMA specializes in ideas rather than building type, whether the project be a house in Fitzroy, a library in Japan, a protest shelter in Tasmania, a plywood bicycle or a suburb eating robot. Andrew Maynard Architects continues to be published in many prestigious international journals such as Mark Magazine [Amsterdam], Architectural Record [US], Architectural Review [London], Monument. Houses A + T [Spain], Architecture Australia, Wallpaper [London] and Pol Oxygen. AMA’s conceptual and built work has been exhibited in New York, Budapest, Melbourne, Sydney, Osaka, Milan, Sao Paulo, Tokyo and more.

Green Buildings Hazardous to Health? Report Cites Risks of Weatherization
The buildings commonly referred to as “green” could actually be hazardous to your health, according to a new report.
That’s one of many warnings out of a new report from the Institute of Medicine, which tracked the potential impact of climate change on indoor environments.
The report cautions that climate change can negatively and directly affect indoor air quality in several ways. But the scientists behind the study warn that homeowners and businesses could also be making the problem worse by pursuing untested or risky energy-efficiency upgrades.
“Even with the best intentions, indoor environmental quality issues may emerge with interventions that have not been sufficiently well screened for their effects on occupant safety and health,” the report said.
To save costs and cut down on emissions, building owners typically find ways to seal off potential leaks and conserve energy. But in “weatherizing” the buildings, they also change the indoor environment.
By making buildings more airtight, building owners could increase “indoor-air contaminant concentrations and indoor-air humidity,” the report said. By adding insulation, they could trigger moisture problems. By making improvements to older homes, crews could stir up hazardous material ranging from asbestos to harmful caulking — though that problem is not unique to energy improvements.
The report did not dissuade homeowners and businesses from making the energy-efficiency upgrades. Rather, it called for a more comprehensive approach, urging organizations to track the side effects of various upgrades and minimize the “unexpected exposures and health risks” that can arise from new materials and weatherization techniques.

Center for Global Conservation
An office building in the Bronx Zoo seems as natural to the site as the surrounding parkland and accommodates multiple programs with minimal resources. Staring out the window is part of the job description.
Employees on their lunch break at the Center for Global Conservation (CGC) recently paused to observe wild turkeys roaming in front of the building. In the northwest corner of the Bronx Zoo’s 265 acres of New York City parkland, this display isn’t a rare occurrence. Nor is the sight of Inca terns swooping in the seabird aviary across from the CGC headquarters. Muskrats and goldfinches visit, too. Perhaps these creatures continue to treat the turf as their own because the rectangular, elongated three-story building — which achieved LEED Gold Certification in 2009 — seems as natural to the site as the two rock outcroppings it bridges.
The CGC, designed by FXFOWLE, houses several Wildlife Conservation Society (WCS) programs. WCS operates the largest network of wildlife parks in the world, including the Bronx Zoo, New York Aquarium, Central Park Zoo, Queens Zoo, and Prospect Park Zoo, and operates over 500 conservation programs in more than 65 countries. Until the new headquarters was completed in 2009, WCS employees were scattered in buildings across the Bronx Zoo. FXFOWLE, which had previously renovated the zoo’s Lion House in 2008, consolidated various programs with diverse needs at an unused edge of the park. After looking at various configurations, the firm designed the building to intrude as little as possible on the landscape, even inflecting it to save two trees. WCS employees now benefit from chance encounters. “It’s really changed our relationship. Proximity is everything,” says Susan Chin, vice president of planning and design and chief architect for WCS.

The Better Way to Know if a Building Is Green
An exhibit at the American Institute of Architects headquarters shows off the LEED for Neighborhood Development rating system
The architecture firm Farr Associates, the Chicago Architecture Foundation, and the U.S. Green Building Council have produced a fantastic exhibit on how to create green neighborhoods. It opened in Chicago last year and is now on display at the American Institute of Architects headquarters in Washington.
This carries some symbolism. When it comes to sustainable communities, the architecture profession has been both hero and villain. It has been a hero because many of the early (and continuing) leaders of smart growth and sustainability in our built environment have been architects, from William McDonough to Peter Calthorpe, from Andres Duany to David Dixon. Frankly, in my opinion, architects were way ahead of the environmental community in forging solutions to sprawl. And it’s a good thing that they were, because they gave us environmentalists something positive to advocate.

Winners of the 2011 Skyscraper Competition
eVolo magazine has run a tidy little competition for the last five years, inviting architects to innovative new skyscraper typologies. Today, the winners of the 2011 Skyscraper Competition were announced and we’ve got a recycling wind turbine, an energy- and water-harvesting horizontal tower, and a re-imagining of the Hoover Dam.
Jury members included SOFTlab principals Jose Gonzalez and Michael Svizos, architecture critic John Hill, Mitchell Joachim of Terreform One, CarloMaria Ciampoli of Live Architecture Network, and a host of other working and teaching architects (see the full list here).
FIRST PLACE: ‘LO2P Recycling Skyscraper’ by Atelier CMJN (Julien Combes, Gaël Brulé)
“The idea behind this skyscraper is to recycle the old cars and use them as building material for the new structure. The building is designed as a giant lung that would clean New Delhi’s air through a series of large-scale greenhouses that serve as filters. Another set of rotating filters capture the suspended particles in the air while the waste heat and carbon dioxide from the recycling center are used to grow plants that in turn produce bio-fuels.”

SECOND PLACE: ‘Flat Tower’ by Yoann Mescam, Paul-Eric Schirr-Bonnans, and Xavier Schirr-Bonnans
Imagined for medium-size cities where vertical skyscrapers do not fit the skyline, the flat tower is a “new high-density typology that deviates from the traditional skyscraper. The medium-height dome structure is perforated with cell-like skylights that provide direct sunlight to the agricultural fields and to the interior spaces. The dome’s large surface area is perfect to harvest solar energy and rainwater collection.”
THIRD PLACE: ‘Reimagining the Hoover Dam’ by Yheu-Shen Chua, United Kingdom
This project merges the programs at the current Hoover Dam — viewing platform, a bridge, and a gallery – into a “single vertical super structure.”
There a long list of honorable mentions, and we’ve highlighted below some especial favorites (clockwise from top left):
‘Sports Tower’ by Sergiy Prokofyev and Olga Prokofyeva, Ukraine
‘RE:pH Coastscraper’ by Gary Kellett, United Kingdom
‘White Cloud Skyscraper‘ by Adrian Vincent Kumar and Yun Kong Sung, New Zealand
‘Seeds of Life Skyscraper’ by Mekano (Osama Mohamed Elghannam, Karim Mohamed Elnabawy, Mohamed Ahmed Khamis, Nesma Mohamed Abobakr), Egypt

Beautiful Underground Aloni House Blends in With the Earth
This stunning underground home by Deca Architecture utilizes a natural palette of materials to maintain a low profile while complementing the serene Mediterranean landscape that surrounds it. Situated in a small valley with views of the coast, the Aloni house consists of two stone walls bridged by a beautiful green roof that spans two adjacent slopes. The home takes advantage of rustic materials that maximize energy efficiency while allowing the house to blend in with the rugged terrain of Greece’s Antiparos Island.
The Aloni house finds its inspiration in the landscape of the Cycladic Islands, which were shaped in the past by earthen retaining walls erected to create land fit for farming. Deca Architecture decided to incorporate this traditional building typology into the design of the house, and the result is a structure that resonates with the topography of its site while taking advantage of low-impact materials that impart high insulation values. The single-level 240 square meter home features walls made of retained earth that regulate the interior temperature thanks to their high thermal mass, while a green roof provides further insulation from the bright Mediterranean sun.

New Green H2Otel Hotel Planned for Amsterdam by Powerhouse Company + RAU
RAU and Powerhouse Company developed H2Otel, a luxurious and completely sustainable hotel for Amsterdam, The Netherlands. The project, a prototype for luxury hotel typologies, is shown at the National Design Triennial ‘Why Design Now?’ at the Cooper Hewitt National Design Museum in New York.
Introduction
How to make a hotel tower more sustainable? As a typology, the modern hotel is at odds with the concept of sustainability. Most of the time they are empty and unused, yet they have to be fully accessible, comfortable and pleasurable all the time. Guests usually enter their rooms in the evening. Large glass planes provide stunning views but also heat up the rooms when no one is there. The biggest energy consumer in hotels is usually the cooling system. So, why are the facades of most highrises the same on all sides, despite their different exposure to sunlight? Apart from that, modern hotels are increasingly build according to global formulas in brownfield locations. How do we create a local sense of place while using the particular efficiency if the hotel typology?
Water
Water is an important theme of the H2Otel. Situated alongside the Amstel river, the hotel is overlooking the historic center with its numerous canals, the docks on both banks of the River IJ and, on a clear day, the North Sea. But the name, H2Otel, does not only refer to its scenic views. Water is the building’s main carrier of energy. Through oxy-hydrogen generators water can be used for heating, cooling, cooking and the generation of electricity.
Efficiency
Fluctuating occupancy rates are an obstacle in reaching efficient climate control, especially in large hotels. In order to improve efficiency, an adaptive, sensor-based climate system monitors and controls the indoor climate in real time and for each room individually. It recognizes the number of occupants in a room and adjusts the level of conditioning accordingly. Conditioning is automatically switched off in empty rooms. This climate system helps to save approximately 40% of the building’s energy consumption.
While innovative technology is an important asset in achieving energy efficiency and carbon neutrality, inventive design solutions make a crucial difference in keeping the building’s demand for energy at a minimum in the first place.

A green answer to Vanity Fair’s architecture poll has its own blindspot
When Vanity Fair recently released the results of a survey ranking the most significant pieces of architecture of the last 30 years — with Frank Gehry’s Guggenheim Museum in Bilbao, Spain, topping the list — the poll was met with extended grumbling. Some people griped about the many architects, including Richard Meier and Daniel Libeskind, who voted for their own work (Vanity Fair indeed!); others noted that the average age of those polled seemed to be around 70.
But the biggest complaint, by far, was that the results seemed completely to ignore green architecture, arguably the biggest single movement in the field since the emergence of modernism a century ago. In response, Lance Hosey, a writer and an architect who worked for years at William McDonough + Partners, a Virginia firm known for a commitment to sustainable design, organized an alternative survey for Architect magazine in which he polled a number of leading green architects and others. (Hosey e-mailed me earlier this month asking if I’d take part in the voting, which I did not.) He used the same format as Vanity Fair: He asked each voter to name the five most important green buildings since 1980, and separately the single most significant sustainable building finished since 2000.
The results were released Tuesday. The winner in the first category was the Lewis Center for Environmental Studies at Oberlin College, a building by McDonough + Partners that relies on solar panels, among other green-design features, to produce 30% more energy than it uses. (Hosey swears his old affiliation had no impact on the results, though the voters did include one current McDonough employee, Kira Gould. Unlike Vanity Fair, Architect has no plans to publish the contents of each ballot; Hosey did tell me, though, that one architect in the poll gave every one of his votes, six in all, to his own work.) Renzo Piano’s California Academy of Sciences in San Francisco, which is topped by an undulating green roof made of native plants, was named the most important sustainable building since 2000.
I don’t have any issues with the winners of Hosey’s alternative survey: I admire both the McDonough and the Piano buildings, and I can understand the desire to confront the obvious limitations of the Vanity Fair project. (Similarly, given the way the Vanity Fair poll was set up, the Guggenheim Bilbao struck me as entirely deserving.) In the end, though, I have the same basic problem with Hosey’s effort as I did with the first poll: Asking voters to nominate single buildings necessarily produces results that give a skewed view of the way architecture — and more important, the way we think and write about it — has evolved in recent years.
Among critics and architects alike, there has been a rising understanding that architecture is not just about stand-alone icons but is tied inextricably to urban planning, real-estate speculation, capital flows, ecology and various kinds of networks — and similarly that architecture criticism means more than simply writing about impressive new landmarks, green or not, produced by the world’s best-known firms.
Indeed, sustainable design and its champions deserve significant credit for helping architecture as a whole adjust its values and move toward a wider, richer sense of how to measure its progress and chart its signal achievements. In that sense, it seems to me that Hosey wound up falling into the same trap as the Vanity Fair tastemakers whose shortsightedness he hoped to correct.
Maybe, in other words, the most important achievement in green architecture over the last 10 or 30 years is not a single building at all. Maybe it’s a collection of schools or linked parks or the group of advisors brought together by a young mayor somewhere. Maybe it’s a new kind of solar panel, a tax credit or a zoning change. Maybe it’s tough to hang a plaque on — or photograph for a magazine spread.

Albert Speer and Partner: Qatar Stadiums 2022 FIFA World Cup
With the World Cup underway, I have kept an eye open for future FIFA World Cup stadium designs. Bingo! Check this out. Hat tip to designboom.
Dubai recently unveiled images of stadiums, designed by german architectural firm Albert Speer and Partner, for the bid of Qatar for the World Cup Soccer 2022. If Qatar wins the bid there will be three completely new stadiums and two existing stadiums that will be subject to extension.
Qatar’s plans to use solar technology to power carbon-neutral technology to cool the stadiums and to make sure the temperature at the games does not rise above 27 degrees celsius.
In order to meet demand post-tournament of Qatar Stars League most of the stages was designed with a higher form that can be dismantled after the world cup.
The concept of hospitality in Qatar is extremely compact and all stages are an hour’s drive from the FIFA World Cup 2022 headquarters which will allow fans to attend more than one game per day. A new and efficient metro system, with a total length of 320 km will be built in 2021. all stages will be connected to the highway system in qatar and to provide easy access for spectators, some may also be reached by water taxi. not only the fans will benefit from this ‘compact’, but also teams that could remain in their base camp for the duration of the championship.
The brand new 45,120 capacity al-wakrah stadium will be located in a sports complex that will consist of an aquatic centre, spa, sports facilities and a mall. the centre will be a bustling centre 365 days a year and is adjacent to the future routing of the doha expressway.
Located in the northeast of Qatar, designed in the shape of a beautiful asymmetrical shell the al khor stadium will have a capacity of 45,330 seats. some viewers will see the gulf from their seats as the players will benefit from a flexible cover that will ensure the shadow on the pitch.
