Costford is a pioneer in introducing low-cost, environmentally friendly construction methods to Kerala. They have developed several proprietary techniques to make construction hassle-free and pocket-friendly. says it can cut costs by up to 40%.
foundation
The Costford architects realized that the floor had to be only 1.5 feet wide. It is said that there is no merit in increasing the floor area unnecessarily. Also, additional costs will be incurred. In addition, the narrower the floor, the less you need to dig a large hole in the ground. Excavated sand can be used for construction. Too much sand or stone to fill the foundation can drive up costs. Placing hard rocks on the foundation and filling the gaps with lime or mud is how Costford’s foundations are made stronger. Concrete can be avoided if the ground is hard mud.
wall
Walls are usually constructed using bricks, mud, or sand and lime blocks. The ideal brick size is 9×4, 5×3 inches. Palm size is ideal. In the case of a one-story house, it is not necessary to build a wall from the center of the foundation. The wall should be built 9 inches wide from the outside of the foundation wall. This helps prevent weakening of the solid bedrock that protrudes outwards.
construction
Costford mainly uses a construction method called the rat trap construction method. This method can reduce brick usage by up to 25%. This is a construction method in which two layers of bricks are laid horizontally with a gap in the center. This empty space will be a rectangle. Interestingly, this helps ensure great air circulation in your home.
Walls can also be constructed with gaps instead of horizontal or vertical to ensure air circulation. This helps avoid windows, which also saves money on wood, glass, and more. Interestingly, this feature can be made attractive by paving the glass.
brick paving
The bricks are paved using the section construction method. Blocks can be selected according to the length of the wall. There is no need to use short blocks to fill gaps between large blocks as this will affect the bond between bricks. Gaps can be managed by leaving space in the middle. First, slaked lime is laid down, and then bricks are laid over it. Slaked lime can be used to fill gaps.
painting
Developed by Costford, this method does not require plastering or painting. Adding a little decorative work to the plaster adds a unique charm to the wall. Wall construction can be finished by leveling the bricks and adding the appropriate lines.
brick lintel
You don’t need iron or concrete lintels to make a four foot wide window or door. Instead, Costford suggests laying a layer of brick over the window and door frames, with the wide side facing forward. On top of that, lay a brick with the narrow side facing you. He lays three layers of bricks on each side, leaving a space in the middle. Install two steel bars in the center and reinforce with concrete. Not only does this reduce construction costs, it also looks great. This feature can be built in arched, flattened or segmented or as a carry-out arch. Perfect for a mud-filled house. Carry-out arches can be designed very cheaply. This way the bottom of the block projects 2.25 inches more than the bottom block.
roof
Filler slab technology is used in roof construction. Make the ceiling before fixing the tiles to the concrete. The advantage of this method is that it is very cheap. In addition, the roof is not too heavy, so it does not put a burden on the walls. This increases the life of the structure.
bamboo
Bamboo sticks are widely used for proofing. Costford uses treated bamboo instead of regular rods. Using attractive Jali pieces in place of windows and reusing reclaimed wood to install a biogas plant are just some of the ways Costford is making their homes so eco-friendly. .
