” Designed by Chenchow Little Architects, this semi-detached house conceals its historical origins and suburban situation. Initially built at the end of the 19th Century, one of the few original remaining features are the sandstone walls at ground level. ‘Simply remodeling the house wouldn’t have given our clients what they wanted,’ says architect Tony Chenchow, a director of the practice.

The site, in Sydney’s beachside suburb of Bronte, slopes down dramatically towards the Pacific Ocean. ‘We wanted to embrace the view, but the original Arts & Crafts style home wouldn’t have allowed us to achieve this,’ says Chenchow. A contemporary first floor addition was ‘grafted’ to the house. Constructed in steel, glass, fibro-cement and encased with aluminium louvers, the first floor cantilevers above the original sandstone walls.

The ground floor of the Bronte house was restored and reconfigured by the architects. Three bedrooms occupy the original structure, while a new main bedroom, ensuite and deck were added to the rear. As the first floor is entirely new, the architects were able to design around a view. ‘You’re not aware of the ocean as you cross the bridge (leading from the garage to the front door). It’s only when you enter that you see the entire vista,’ says Chenchow. As the street is on the high side, one enters at the first floor.

Chenchow Little’s design features a series of verandas, decks and courtyards. A long corridor, linking the kitchen and living areas, is more akin to a ‘breezeway’ with external aluminium louvers. ‘It’s not supposed to be clear what is inside and what is outside,’ says Chenchow, who worked closely with co-director Stephanie Little. ‘The louvers are fundamental to the design. We wanted to protect the house from the harsh light. We also wanted to ensure privacy from the neighbouring home,’ he adds.

The first floor spaces are loosely defined from the courtyard and decks. The front room, used as a family room and office, has a large sliding door leading from the breezeway. The dining and living areas at the rear of the home are also flexible. Glass sliding doors frame this space on three sides, one of which leads to a covered deck, the other being roofless. ‘The wind can get fairly strong so we wanted to ensure the outdoor areas could be used for most of the year,’ says Chenchow. The architects were also keen to ensure views to the ocean could be seen from the central courtyard and kitchen.

The house has many features associated more with an inner-city warehouse rather than a house near the beach, including a sense of boundless space. ‘When you’re inside, you’re not aware of neighbours,’ Chenchow explains, ‘so the focus is directly towards the water as soon as you get past the front door’.”

” Here’s a second new project by Dutch architets UNStudio: these images show a proposed flagship store for fashion house Louis Vuitton in Japan.

The location and construction schedule of the ten-storey building are secret for now.

The following information is from UNStudio:
–

Flagstore Louis Vuitton, Japan

The design for the 10 storey (54 meter tall) flagship Louis Vuitton store in Japan aims to establish an architectural equivalent of the identity of Louis Vuitton in which classical and modern qualities are blended, reinforcing each other. The design inspires the visitor with a feeling of being in the House of Louis Vuitton by celebrating the qualities that make up the essence of the company, its products, its history and its future….”

SITE

This project addresses the proposed redevelopment of the former RAF airbase at Upper Heyford, Oxfordshire (UK). The site is owned by the North Oxfordshire Consortium, which intends to redevelop the site for mixed use. In 2007 a Planning Application was submitted to Cherwell District Council for the development of 1000 dwellings and creation of 1500 jobs.

This project provides an evaluation of the Bioregional context of the site and sets out broad proposals for an alternative sustainable development comprising 1000 houses and creating 1500 jobs based on the Bioregional approach. The aim is to create a framework for development of a sustainable community which minimises carbon emissions and ecological footprint, provides for a healthy and fulfilling quality of life and builds a strong community.

In the UK, for a “standard” house (and life style) built to the 2002 Building Regulations, 40% of the ecological footprint is attributable to transport, food and distribution. Therefore, to provide for a sustainable community there is a need to promote low carbon lifestyles and activities through design of the buildings, community and its relationship with the surrounding region or Bioregion. The Bioregion is the area within which most of the interaction between the community and surrounding area occurs.

Maximising interaction with the Bioregion and minimising the size of the Bioregion closes the loop and minimises energy use (especially for transportation) and waste.

RESOURCES

A- Water

The site is located on the Great Oolite major aquifer which is used in the area for water supply by a number of farms, the groundwater is generally at a depth of 10-15m below ground surface at the site and water quality is generally good

Groundwater supply boreholes are proposed in the main CHP compound where there will also be a water treatment plant for disinfection, adjacent to the fish farm and in the north western part of the site to supply the brewery and other industries in this area.

B- Energy
Presently Upper Heyford is being provided electricity by Southern Electric and Gas by British Gas. The overall aim of the development is to minimise carbon emissions (zero carbon) and minimize the ecological footprint of the site. This leads to a hierarchy of design principles as follows:
- reduce the energy demand by creating energy efficiency buildings and businesses;
- reduce the energy use in transport by creating an environment where living without cars is possible and public transport is convenient;
- generate energy using renewable sources within the bioregion;
- generate energy within the footprint of the site where possible;
- make sure that energy, if utilised from the national grid is from a renewable tariff

On the site, three wind turbines of 40m diameter each are proposed, generating 600kW each, giving a total of 1800kW. However, since wind turbines completely depend on an unreliable source like the wind for power generation, a back-up gas powered CHP has also been provided for in the northern part of the site.

A CHP is located in the southern part of the site, in close proximity to the new proposed community. It is multi-fuel, fired either by wood pellets from the Woodland Coppice on site or by straw from nearby farms. The CHP provides 400kWe of power supplying electricity and heat to the 1000 houses and to the retail, offices and public spaces in the area.

C- Waste
The proposed new development aims to reuse and recycle a large proportion of the waste produced on site in the following way:

D- Sewage
Reed Beds and the Living Machine has been proposed for the new development of 1000 houses The domestic population for the new community is estimated between 2500 and 3000 people giving rise to a minimum of 54,000 litres of sewage per day [Pollution Prevention Guidelines, SEPA]

A proposal has been made to divert recycled grey water, a considerable amount coming from a small settlement of 1000 households itself as per the figures above, from the plant to the Woodland Coppice to provide enough water to sustain a three year coppice (Willow) on this otherwise dry site and adequately fuel the multi-fuel CHP’s.

E- Domestic Waste
Segregation of waste into recyclable (glass, plastic, paper and metal) and bio-degradable waste (kitchen and garden waste) has been included in the design concept. Recyclable waste could be easily transported to the recycling centres in the region. An Anaerobic Digester has been provided close to the CHP in the south of the site for making the best use of bio-degradable waste.

“GROW” RESIDENTIAL DEVELOPMENT & ITS COMMUNITY

This projects tries to combine and integrate ADAPTABILITY & NATURE.

1. ADAPTABILITY because it is a moment of quick changes in our society ( We encounter different kind of population and different needs as well as demands.
2. NATURE because people like living in Natural Environments. They like going outside and enjoying the nature and their environment. I wanted to give them “THE FEELING OF LIVING IN NATURE“.

Also, I wanted to deliver a ENERGY EFFICIENT BUILDING, and to do so I based my design under the criteria of SUSTAINABITY AND PREFABRICATION —> which will generate a HIGH QUALITY building.

Then, I came across with the IDEA of a building that can GROW.

So, how can the building grow? Some of the guideline might be as follow: In the case of AFFORDABLE Houses the government will provide the TRUNKS. For example, “Planting trunks” as part of the URBAN DEVELOPMENT (as an extension of the roads), and people would buy their prefabricated PODS and PLUG-IT to the building.

—————————————————————————————

—————————————————————————————

SUN STRATEGY: PASSIVE SOLAR & DAYLIGHT DESIGN

All pods are facing south to maximise the solar gains in the summer.

There are 3 columns of Pods. Columns A and C are stagered so that they can better follow the Sun Path to allow the most sunlight to penetrate to the interior of the building.

As illustrated on the Sun Angle Diagram, we will try to avoid the solar gains in the summer (angle between 45º - 65º) to control the overheating. We will place each pod in section in a position in which they can benefit the most from the middle season solar gains (Angle between 20º - 45º). As shown on section 1-1 the North placed Pods are able to enjoy the sunlight benefits as much as the South row.

Also, in plan the design of the prefabricated Pods envelope helps to collect the maximum sunlight for the back row of Pods following the sun path as illustrated on the typical floor plan.

To protect the Pods form the high temperatures in summer the building is design to provoke an air flow of fresh air raising through the interior of it (see summer air flow diagram).
