Treehouses Around the World

Treehouses Around the World.

 
   





 
One thing we all seem to have in common is we all love treehouses. You can find all of the treehouses in this collection plus many others in this Natural Homes album on our Facebook page.

This beautiful treehouse is by Christy Collard from Cork, Ireland. Christy specialises in organic, spiral designs. His facebook page is at  and deserves far more than the 265 Likes it currently has. You can read about his work at a small reforestation project in Lalibela, Ethiopia where he created some beautiful spaces.   This is 'La Cabane Cocon' (The Cocoon Treehouse). It uses a light steel framework to support the woven branches but otherwise it natural. The same structure could be built with a bamboo frame or similar. It was built by Jean-Yves Behoteguy, a French 'sculpteur sur bois' (sculptor of wood). Here's a video of 'La Cabane Cocon'.   This is 'The Gibbon Experience', a lush and peaceful jungle where you can learn how to find fresh water in the vines and which flowers and plants are edible. The treehouse is on three levels, three bedrooms, a living room/kitchen area and a bathroom all accessible by zip lines.

This is probably the least invasive version of a treehouse being supported by straps from higher branches rather than anchored into the trunk of the tree. It's a design from ErlebNest who also sell components to make your own treehouse. The cocoon like part of the design is a sleeping pod that has a canvas to cover the top if you're not quite ready for a night under the stars.   Finca Bellavista is a residential treehouse community for about 100 people in the south Pacific coastal mountains of Costa Rica. Its 23 treehouses and 27 zip-lines are set in a rustic, comfortable, solar and hydro off-grid retreat of 300 acres of forest saved from the loggers. Here�s more about the community on YouTube with a gallery of their treehouse pictures.   This Hemloft was made using reclaimed materials, some of which came from Craigslist. Like all unique shelters this treehouse, by carpenter Joel Allen, was a labour of love. Even with good knowledge of the woods where it stands, it took Joel months to find just the right tree. The egg shaped bubble, wrapped around the trunk of the tree, is reminiscent of the Yellow treehouse  in New Zealand.

This treehouse was discovered by Joseph Ebsworth who has set himself the task of finding all the hidden treehouses and huts in the woodlands and forests of ski areas. Happily their location will be kept a secret but if you give his blog a visit from time to time you're bound to be entertained by his latest discovery. This particular treehouse in Breckenridge, CO, USA was built with all natural and reclaimed materials from the area.   This is a POSH (Port Out Starboard Home) treehouse built by The Treehouse Company for The Lodge, a five star hotel on the banks of Loch Goil deep in Argyll Forest Park in Scotland. It's used for dinning with a wonderful view of the loch while snuggled up to its wood burning stove.

The treehouse sits in a very English garden near Bristol sensitively hugging an oak without anchors in the tree. The thatched treehouse, covered with hand cleaved oak shingles, stands on a ringbeam supported from the ground on stilts. If you were lucky enough to visit this gently beauty you would see the magnificent views of the imposing Clifton Suspension Bridge.

木栱屋 The Sami (indigenous skandinavian) Goahti (turf home)

These are the building stages of a Sami (indigenous skandinavians) arch-beamed Goahti (turf home). This one was built for the International Indigenous Festival, Riddu in Samuelsberg, Norway. The frame is made from birch roundwood pegged together with wood; no nails are used. Poles of roundwood are laid against the frame, pegged and covered with overlapping sheets of birch bark which are kept in place by layers of turf stacked against the sloping walls.    
   

     
The arch-beamed goahti is called a bealljegoahti in Sami. It consists of an inner framework of two sets of curved wooden beams, called bealljek. To get the curved trees you have to look for birch growing on hillsides. The trees there bend near the root to be able to grow straight up. The whole structure sits on stones with the final weight of the turf and its parabolic profile giving it stability.

Literature, dating back to the 1700s, explains how the goahti was divided into nine areas. The areas were marked by logs or stones. The main division went straight across from the entrance to the back wall. In the middle of this was the fire place (arran in Sami). On both sides of the door were logs that defined a path to the fire place. The space between the door and the fire place is called the 'uksa'. From the fire place and back towards the back wall there were also two wooden logs. This space is called 'boassu', and is the spiritual space in the home. The rooms on either side of the fire place could be divided into several sections where people slept, ate and worked.

Different female goddesses occupied the uksa, boassu and arran and there were social rules that determined where different family members and guests should stay in the home.
   
At the front and back of the home are stone vents, seen here (above) just at the builder's feet and the picture left, which also shows the lower layers of birch bark held in place with a thick heavy layer of turf. All the materials, wood, bark, turf and stone are found locally. With regular maintenance a bealljegoahti will stand for many decades. You can see the remains of an abandoned Swedish goahti (a torvkåta) on the Natural Homes Facebook Page
   
       
   



 
     
   

A goahti like this with a diameter of about 5m (16ft) will use around 200 small trees. If straight trees are not available then during midsummer the poles can be pressed under large rocks to dry and straighten. All the trees should be stripped of their bark with a drawknife. The ground inside the goahti is slightly sloping towards the door with all parts of the interior slightly raised in relation to the uksa.

田埂種「蠅翼草」 稻田養分不怕被搶


宜蘭綠色博覽會邀屏東育苗協會到縣內推廣環保田埂,利用種植「蠅翼草」防治惱人的田埂雜草,避免使用除草劑。

鄉下田埂經常長滿惱人的雜草,過去農民多以除草劑防治,宜蘭綠色博覽會引進「蠅翼草」種在田埂,減少雜草也避免除草劑汙染。

由於稻田水源豐富,土壤又肥沃,田埂兩旁長滿雜草,與水稻搶食土壤養分,農民噴灑除草劑,不但汙染水源、土壤,也影響稻子生長,縣府農業處昨天請來屏東縣育苗協會人員推廣「生態田埂」。

屏東縣育苗協會理事長林清源表示,利用蠅翼草覆蓋田埂的表土,讓雜草種子沒辦法入土發芽,且蠅翼草的耐旱特性不喜多水,因此只長在田埂上,不會蔓延到水田中與稻子分搶養分,更重要的是,一年四季都能活,不必刻意整理,「生態田埂一年節省15000元除草劑成本」。


縣府農業處農務科長楊槐駒表示,雖然除草劑在國內仍是合法用藥,但宜蘭縣政府自去年底開始分階段禁用除草劑,因此得知屏東縣育苗協會的生態田埂概念,專程邀請到宜蘭宣導。

農業處也已開始推廣試種,以有機農業園區做基礎,歡迎有興趣農民向農業處詢問登記。

Algae-Powered 海藻發電 綠能街燈 (Street Lamp)

 
法國生化學家Pierre Calleja花了數年時間,研發出海藻電能街燈(Algae-powered Street Lamp)。正如許多植物一樣,海藻是靠光合作用生長,即吸收陽光中的養料,釋放出氧氣,部分海藻種類還可以混合培植,即它們不但可透過光合作用生長,更 可攝取有機碳獲得能量。


可檢測碳排放量

設計師利用海藻的特性製作出一個圓柱形燈箱,裡面裝滿水和海藻。海藻在白天會從陽光和空氣中的二氧化碳裡吸取養分,釋放氧氣轉 化成能量儲存在電池中,便可在晚上為電燈供電照明。此外,海藻電能街燈也可在黑暗的地下車庫中使用,海藻吸收汽車釋放的二氧化碳廢氣後,可提供照明用途和檢測碳排放量,而在家居或其他場合,海藻也能靠吸收自然光製造能量照明。





Designer Mike Thompson has created an incredible living lamp that is powered by algae! Spotted over at Designboom, the Latro Lamp derives energy from an algae chamber that requires just sunlight, CO2, and water to operate. Stick the lamp outside, breathe into it, and voila, you've created your own bio battery-powered living lamp.








This algae-powered lamp transforms CO2 into light.
Designed by Mike Thompson, the Latro Lamp gets energy from an algae chamber and needs just sunlight, C02, and water to operate.
The lamp is made possible thanks to a recent discovery made by researchers at the universities of Yansei and Stanford. The researchers found that a tiny electrical current can be extracted from algae during photosynthesis. The Latro Lamp features a battery that stores energy generated by the algae throughout the day and a light sensor that controls the lamp's intensity, preventing the algae from becoming malnourished. Thompson believes this discovery could lead to an algae revolution: 「As advances in nanotechnology lead to increasingly energy efficient products, plant life such as algae will become attractive sources for tapping energy,」 he says.
For now, though, the Latro lamp remains an idealistic design project — after all, who realistically wants to care for a lamp like a household pet?
