WHAT IS AN ECO-FRIENDLY CONSTRUCTION?
• Eco-friendly construction is about building a structure that is non-harmful and beneficial to the environment and its residents
• This eco-friendliness is achieved through:– An eco-aware DESIGN– Using MATERIALS that are natural and local– Using METHODS that save energy and material during
construction; and harnesses natural elements to provide health and comfort instead of energy- intensive alternatives
– A trained and well cared for LABOUR
AN ECO-HOUSE IN ALIYAR
• Identified a flat expanse at client’s site (on a mountainous terrain) and thereby avoided unnecessary leveling
• Avoided trenched-foundation and used tree poles instead – To not disturb or be disturbed by wild animals– To use abundant local material (wood) and avoid energy intensive
trenching and hauling boulders from long distance
• An open layout to maximize light, air and space

Why Wood?
AN ECO-HOUSE IN ALIYAR
• Aliyar has an abundance of coconut, palm and bamboo trees
• Transporting boulders, bricks, sand, cement, steel and concrete machinery would be difficult and high on energy
• Finding and retaining regular brick-and-mortar labor in a remote site would be impractical
METHOD• A palm pole based foundation overcame
trenched-foundation-related issues• At ten foot raised basement provides protection
from wild animals and wetness of the wooden flooring due to rains
• Simple varnishing on matured coconut wood panels retains a natural look without need for plastering
• Wooden roof covered with alloy sheets provides effective protection from heat and cold
• Wood panels with interlocking edges, simple nailing and coconut wood beams totally avoids any use of steel

Eco-Friendly Methods
Applying Linseed Oil over wood planks
Alloy sheets over wood roofing Interlocking wood panels
• Experienced labour is not available for non-standard work (like a wood house)
• Had to hire un-trained carpenters and guide them on a daily basis
• Had to adopt an experimental attitude towards work and team
• Arranged for the team accommodation, food and medical care
• Offered the team a large end-of-the-job cash incentive

THANK YOU!
FIRST STAGE• Locations for pillars marked• Earth work excavation for the
pillars : 2’x2’x2’6” • Base concrete: 6” thickness• Erected the 12 feet palm trees 2’
into the foundation• Poured the concrete in the
foundation around the palm tree to prevent termites
SECOND STAGE
• 3”x6” coconut wood beams installed on the palm tree grid as base for flooring
• 2” thick coconut wood planks were laid on the beams to create the floor
THIRD STAGE• 4”x4”x7’ coconut wood posts
were erected on top of the palm poles for walls and roof support .
• Height of the posts on inner side is 9’
• Roof skeleton: 2”x3” & 2”x4” wooden beams
• First layer of the roof : 1” thick wooden slabs.
• Second layer of the roof: Zinc-alloy sheet.
FOURTH STAGE
• Walls were erected with 1.5” thick wooden slabs. By using nails & fevical.
• Doors and windows frames were also made with coconut wood.
• All furniture (dinning table, kitchen table, chairs, etc.) in coconut wood were completed as part of the project
