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
ECO-AWARE DESIGN:

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
![Page 8: How to build a Wood house](https://reader033.vdocuments.mx/reader033/viewer/2022061210/548eeb5db47959aa0d8b45de/html5/thumbnails/8.jpg)
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

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
