Birds in the blocks
Not concerned that they were designed for House Sparrows, a Blue Tit family has been incubating their brood in one Union Street Urban Orchard ‘duplexes’ over the last few weeks.

The adapted readymades, fashioned from a standard Lignacite block, were the first prototypes installed for the 2010 London Festival of Architecture, so its fitting that they were also the first to be occupied.
Commissioned by the Architecture Foundation as a permanent legacy for the festival, Nestworks feature in the ‘Union Street Urban Orchard Book : A Case Study of Creative Interim Use’ which will be available from The Architecture Foundation website and at the book launch tonight.
Urban Birds
Around Valentine’s Day courting birds across the UK will begin inspecting potential nesting sites. Informed and inspired by ornithological derives with Peter Holden MBE, 51% studios architecture has planted scores of ‘assisted readymades’ across the Bankside Urban Forest to increase the variety of nesting options open to its urban birds, many of whom are on the endangered list.
We discovered that the standard hollow block used to build some of London’s most celebrated architecture is made from concrete bulked with recycled woodshavings, a material that when used in nestboxes is proven to fledge more young than any other.
Synergistically the interior block dimensions are text book size for house sparrows, radically in decline in the area. Other species designed for are blue tits, great tits, starlings, wrens, robins and blackbirds.
A website, www.urbanbirds.net, launches on Valentine’s Day to allow nesting activity to be tracked by families and bird lovers across the area. Nestworks is a public project and a people’s project, commissioned by the Architecture Foundation as a permanent legacy for the London Festival of Architecture.
The Emerald Necklace
The site has a unique location. The Upper Rio Grande Events and Recreation Complex’s grounds and buildings will be the first thing you see when you approach the historic town of Creede, from any direction. Along the Silver Thread Scenic Highway, the site and the Willow Creek Conservation Area become one gem in an emerald necklace of scenic valleys stretching up the Rio Grande. Proposals for its development must provide a project which is at once an authentic signature for Creede and a fitting ‘jewel’ in the necklace.
The architecture and landscaping is an extension and embodiment of Creede and the very visible spirit that has created it. The attitude and spirit of the mountain settlers was, and continues to be, unique. Local architecture reflects the values and sensibilities of its people, and this is particularly visible in places somewhat off the beaten track, where people have had to wrestle with available raw materials to survive and to make their livelihoods.
51% studios are using the same kind of thinking that’s been used for well over 100 years in this valley, using the local site conditions and materials in frank ways that reflect awareness of their inherent attributes.
Cable Suspended Sod Roof
Dotted around the valleys near Creede our eye was caught by traditional sod roofed potato cellars. Not only did they sit well in the landscape, but they used regional materials intelligently to create an authentic, inventive eco-architecture. Our green roofs are hung on cables traditionally used for mining activities, using a fraction of the material a beam would to support the considerable snow loads and additional load of by a green roof. By in addition earthlinking the buildings and using geo-thermal heat, we have brought this home-grown technology current.

Green roofs have significant benefits both for the public/community and for the individual building owner. Primary public benefits include controlling stormwater runoff, improving water quality and improving air quality. The most significant benefits of green roofs for building owners are reductions in building operating costs, significantly longer roof life and lower life-cycle costs for the roof, and increased property value.
The green roof serves as a filter to reduce pollutants in the water and also to lower the temperature of the water that is eventually returned to the watershed.
Although a green roof initially costs more than a conventional roof — $10 to $20 per square foot for a green roof versus $5 to $10 per square foot for a conventional roof — they more than make up for that difference over time. Green roofs extend the lifespan of the roof membrane significantly by protecting it from sunlight and temperature variations. As a result, green roofs can conservatively be expected to last two to three times longer than a conventional roof. Experience with green roofs in Germany shows that 40+ and 50+ life spans for green roofs should be expected.
Because of their insulating properties, green roofs reduce the heating and cooling costs for buildings by at least 10 to 15 percent. A Canadian study showed that a 6-inch extensive green roof can reduce heat gains by 95 percent.
On the banks of Willow Creek, green roofs will also improve the aesthetic quality of the buildings, to soften them and integrate with the native prairie landscape, using desert plants which need low or no maintenance.
The steel structure of the indoor arena however quickly becomes expensive if asked to take on a sod roof in addition to snowloading. Structures that carry load through pure tension (hanging) require a fraction of the material required by bending structures such as beams or trusses and provide an efficient way of carrying an extensive green roof in addition to non-uniform snow loads.
Flexible Masterplan
It may be still snowing in Creede, but here at 51% studios we’re working hard at work on the development of the sustainable masterplan for the Upper Rio Grande Event and Recreation Complex [formerly known as, and still encompassing, the Mineral County Fairgrounds] which has been made possible by the El Pomar Grant Award.
Phase 1, which included remediation, relocation of willows and the outdoor arena, is complete and has affored the community of Creede a safe, beautiful and windfree place to rope and ride.
