When people say “mud house” they usually picture an old village hut. A modern earth house is different: its walls are made from soil, but pressed into strong, stabilised blocks. Here’s how it compares with the concrete house most people build around Hyderabad.
Last checked:
Cob or sun-dried mud bricks with no stabiliser. Cheap and cool, but they need regular care in heavy rain.
Damp soil packed hard into formwork to make solid walls. Strong and beautiful, but slow and needs skilled crews.
Soil with a little cement, pressed into precise blocks and cured. This is what we build with.
| Earth-block (CSEB) house | Concrete-frame house | |
|---|---|---|
| Structure | Load-bearing earth-block walls carry the roof | A concrete frame of columns and beams, with brick or block walls in between |
| Height | We build up to G+2 | Can go much taller |
| Comfort in summer | Thick earth walls take in heat slowly and give it out at night | Concrete roofs and thinner walls heat up through the day and can stay warm into the night |
| Finish | Walls can be left bare | Plastered and painted |
| Carbon | Much lower: no fired bricks, less cement | Higher: cement, steel and fired bricks |
| Rain | Needs a raised plinth, overhangs and drainage | Needs waterproofing and maintenance too |
| Familiarity | Fewer masons know it, so pick a builder who does | Every contractor knows it |
A CSEB house compared with a typical concrete-frame house
Thick earth walls have a lot of thermal mass. On a hot day they take in heat slowly, so rooms stay cooler in the afternoon, and they give the heat back at night when it’s cooler outside. Shade, roof overhangs and cross-ventilation matter just as much, and we design for all of them.
We don’t yet have measured temperatures from our own homes in Hyderabad. We’ll publish them once there are homes to measure.
A stabilised earth-block house is. The Auroville Earth Institute has used CSEB for load-bearing buildings for decades. We build homes up to G+2 with load-bearing earth walls.
It can be, mainly because the walls need no plaster and less mortar, and the blocks can come from your own soil. The total depends on the design, the site and the finishes. Ask for a quote you can compare.
A well-designed CSEB house needs a raised plinth, overhangs and good drainage to keep water off the walls. With those, it doesn’t need more care than a plastered house.
Tell us about your plot. We’ll call you back, usually within two working days, and talk through whether earth blocks suit it.
