CLIENT PROFILEDeclined rapidly in the last 20-30 years with a decrease of 10 million in the UKalone. The species is now a Red List Species.Decline Theories• Methyl tertiary butyl (MTBE) in unleaded petrol can affect the abundance of insects for feeding young and this creates poor conditioned chicks.• Autumn sown cereal crops leaves little stubble for the birds to forage in or spilt grain to glean.• Predation - increasing number of cats• Modern building have fewer holes & crevices for nesting• Collared Doves compete for a greater share of the same food types• Urbanization of green spaces
• Set aside an area of garden to grow wild• Plant insect & caterpillar friendly trees such as: apple, oak, birch, willow and alder.• Plant for butterflies who will in turn lay eggs supplying the birds with caterpillars in spring.• Nest boxes need to be near to house eaves/outbuildings.• Many boxes needed, as they like to nest in colonies• Boxes 2m above the ground, north to east sides of house to avoid hottest sun and coldest winds.• Seed baring plants for adults.• Provide bird and dust baths.• Provide shrubs such as: hawthorn, elder, blackthorn and buddleia
EXISTING DESIGNS RELEVANT TO THE HOUSE SPARROW. The Almost InvisibleProtecting Urban Songbirds Project MirroredBy Nan Wen 2011 Tree House
3D DESIGN SKETCH ‘SPARROW CONDO’I was able to make this sketch by a process ofcutting the panels into 5 equal lengths, and placingthem to make a hexagon shape. By placing the roofback on the design this gave me a developmentidea.
The sketch gave me an idea to create 5 separate ‘condos’ thatcould be detached for cleaning and hanging separate if needed.
I had an idea to createa design that you couldadd to as many timesas needed, to create a‘Tower’ of homes for agrowing colony ofHouse Sparrows.I also designed it so thefront panel was clearplastic/glass soobservation byscientists andconservationists couldbe carried out.Although this would begood the sunlight wouldbe dangerous andpredation would beevident.
I needed to create a cup like shape for myclient because they prefer a cup like nest.So I ditched the glass shape and made itinto a sphere.I still wanted to use the wood so made afront entrance.I liked the shape the wing of the HouseSparrow makes so I designed the porch in afanned out wing shape.The problem with this design is that thesunlight would make the birds very hot andthe glass would lose too much heat in thecolder days.
I developed the sphere shape without the ‘garden box’ attached and came up with an idea that the spheres can be hung from any of the hooks to utilize the smallest of spaces.I took the idea of a ‘gardenbox’ from my 3D sketch, andtranslated it with help from myclient profile. I don’t really likethe shape of this designthough, it would not bepractical to produce.
Sphere shaped nest box as the house sparrow prefers dome shaped nests. I added a ‘garden box’ to allow for the planting of plants that attract insects for the birds to eat.I liked the previous idea so decided to develop it further andcreated my final design idea.
I thought about the ‘Community Hub’ need of the House Sparrows since they nest in their colonies, and created a hub of three with different facing holes since sometimes House Sparrows bully other species if they happen to nest next door. I added a dust bath and a water tray since research showed they proved popular and hopefully would attract them. But the weight of this would be considerable.If I made one with the intention tomake several and hang nearbyone another ontrees, outbuildings, fences etc, itwould create a ‘Community Hub’.
Steaming techniqueMain issues:• Over hang of the roof• The balsa wood was too thin for steaming and was offering to snap• Couldn’t fix the steamed wood to the frameSuccesses:• Cut and slot technique• Steaming technique (if used with thicker wood)
Steaming Technique using upcycling of an old painting on hardwood.
