Building Materials for a House in Hyderabad: Deccan Rock, Black Soil and Heat
What to build a Hyderabad house with: brick, fly ash or AAC walls, an insulated roof, Tandur and Shahabad stone, and indicative Telangana SoR 2026-27 prices.
Published on 10/17/202611 min read
For a house in Hyderabad, build the walls in fly ash or burnt clay brick, and switch to AAC block on the west face. Put an RCC roof slab over them with insulation and a pale top. Floor it with Tandur or Shahabad stone, with granite where floors work hard. Footings usually rest on granite or firm murram, but test the soil first if your plot has black clay.
Hyderabad is hot rather than wet, so the roof and the west wall matter most. Below are the reasons, with indicative prices from the Telangana Schedule of Rates 2026-27.
About the numbers below: climate figures are IMD averages for 1991 to 2020, and material properties come from the BIS standard or BEE code named next to them. Prices are indicative rates from the Government of Telangana's Common Schedule of Rates 2026-27. They are not dealer quotes. They leave out GST and, for bricks and stone, transport to your site. The U-values are our own worked examples using BEE's published material values, not test results for any product.
What Hyderabad's climate and ground ask for
Heat matters more than rain
IMD's climatological table for Hyderabad (1991 to 2020) gives a mean daily high of 39.7 °C in May and 38.2 °C in April. Even the May nights average 26.6 °C, so the house gets little chance to cool down overnight. The highest May temperature on IMD's record is 44.5 °C, on 12 May 2010. Winters are mild: the mean December low is 15.3 °C.
Rain averages 860 mm a year over about 50 rainy days. About 73% of it falls from June to September, and August is the wettest month at about 204 mm. BEE's residential code, Eco-Niwas Samhita 2018, puts Hyderabad in the composite climate zone. In practice: design for a long, harsh summer first and the monsoon second.
Granite underfoot, black clay in pockets
The Central Ground Water Board's aquifer report for Hyderabad district (2022) describes the city as resting on Archaean pink and grey granites and granite gneisses. It notes granite hillocks in areas such as Banjara Hills, Shaikpet and Malkajgiri, and mostly red soils on top. The weathered layer above solid rock is generally 5 to 25 m thick.
Black soil is the exception, but it does occur. CGWB's groundwater brochure for Ranga Reddy district lists red soils, medium black soils and mixed soils. It records Deccan trap basalt plateaus in parts of the district and red-brown and black clayey soils on low-lying plains. Black clay swells when wet and shrinks when dry. IS 2911 (Part 3) gives black cotton soil as its example of an expansive soil and covers under-reamed piles as one way to found on it. Leave this to a soil test and your structural engineer. A separate MOA post on black cotton soil foundations is planned.
Earthquake and wind
In the town list of IS 1893 (Part 1), Hyderabad is in Seismic Zone II, the lowest of the four zones, with a zone factor of 0.10. We read the 2002 edition's annex. BIS notified a 2025 revision with a new map in November 2025, then withdrew it in March 2026 and reverted to the 2016 standard, as ETV Bharat reported. Zone II still calls for proper RCC detailing, but seismic loads do not drive material choice here. IS 875 (Part 3) gives Hyderabad a basic wind speed of 44 m/s. That matters most for sheet roofs, pergolas and water-tank stands on the terrace.
Walls: red brick, fly ash brick or AAC
All three are sound choices in Hyderabad. What decides between them is heat, not strength.
- Burnt clay (red) brick. IS 1077:1992 grades bricks into classes from 3.5 to 35 N/mm² by average compressive strength. It caps water absorption at 20% by weight up to class 12.5 and at 15% above that. The traditional size is 230 × 110 × 70 mm.
- Fly ash brick. IS 12894:2002 sets the same absorption limits for fly ash-lime bricks and a drying shrinkage of no more than 0.15%. The state favours them: the Telangana Schedule of Rates requires government works within 100 km of a coal or lignite power plant to use fly ash bricks, citing MoEF&CC notification S.O. 254(E) of 2016.
- AAC block. BEE's tables give it a density of 642 kg/m³, against 1,440 to 1,920 kg/m³ for solid burnt clay brick, and it insulates far better.
Using the material values in Eco-Niwas Samhita's Table 7, we worked out how much heat each plastered wall lets through (its U-value; lower is better):
| Wall, with 12 mm plaster both sides | Approximate U-value (W/m²K) |
|---|---|
| 230 mm burnt clay brick | 2.1 to 2.3 |
| 230 mm fly ash brick | 2.1 |
| 200 mm solid concrete block | 2.9 |
| 200 mm AAC block | 0.8 |
Our guidance: brick or fly ash brick is fine for most walls. Use AAC, or a cavity or insulated wall, on the west face and on bedrooms that take the afternoon sun. That wall faces about 40 °C highs from April to May. Whatever you buy, ask for the BIS licence number and a recent test certificate for strength and water absorption.
Roof: deal with the heat first
A flat RCC slab is standard in Hyderabad, and on its own it is the hottest surface of the house. Our worked figure from BEE's values for a bare 150 mm slab with ceiling plaster is about 3.1 W/m²K. Eco-Niwas Samhita sets a maximum roof U-value of 1.2 W/m²K for every climate zone. Strictly, the code covers residential buildings on plots of 500 m² or more, but it is a sensible target for any house. About 25 mm of expanded polystyrene (BEE value 0.035 W/mK) over the slab brings the figure to roughly 1.0 on paper. More is better.
Our guidance: lay insulation under a screed or tiles, finish the top in a pale, reflective colour, and shade part of the terrace. Slope the slab to its outlets before the June rains. Most of the year's rain comes in four months, so ponding on a flat roof shows up fast. Waterproof the slab properly, and turn the membrane up the parapets.
Floors: Tandur, Shahabad and granite
Hyderabad has two traditional flooring stones close by, and both are limestones that split into flat slabs.
- Tandur stone comes from Vikarabad district in Telangana. The Vikarabad district industrial profile says Tandur is famous for its blue and yellow limestone, and has about 500 small stone-polishing units that sell it as Tandur flooring stone.
- Shahabad stone comes from Kalaburagi district, across the border in Karnataka. An Indian Bureau of Mines inspection report (2025) describes the Shahabad Limestone Formation as flat-bedded, bluish-grey limestone, including a flaggy limestone member.
Look for slabs that meet IS 1128:1974. It allows no more than 0.15% water absorption by weight, a transverse strength of at least 70 kg/cm², and thicknesses from 15 to 95 mm. Rough slabs suit verandahs, utility areas and steps. Polished slabs suit living rooms.
Our guidance: polished limestone is softer than granite, so use granite for kitchen counters and heavily used thresholds. The Telangana SoR rates polished granite at roughly eight to twenty times the price of the local slabs.
Teja Boga's Team G Farm House on MOA shows this palette: a rough stone wall, a perforated clay brick screen, dark stone verandah floors and roofs that shade the walls.
Plaster, finishes and the local rock
Cement plaster over brick or block is the norm. Telangana's SoR says government works must use manufactured (rock) sand and river sand in a 50:50 ratio, following G.O.Ms.No.37 of 2018, so expect crushed granite sand in mortar and plaster. Our guidance: on exterior walls, use a light colour, add drip grooves under sills, and build chajjas deep enough to shade west and south windows in the afternoon.
Granite is also the local walling stone, quarried close by. Rough-dressed granite suits plinths, boundary walls and feature walls.
Indicative prices: Telangana Schedule of Rates 2026-27
Indicative rates, not quotes. From the Government of Telangana Common Schedule of Rates 2026-27, effective from 1 June 2026. These are the government's material rates, excluding GST and seigniorage. Bricks and stone are priced at the quarry or kiln, before transport. AAC and concrete blocks include delivery. Per sq ft and per bag figures are our conversions.
| Material | SoR 2026-27 rate |
|---|---|
| Burnt clay brick, 230 × 110 × 70 mm (IS 1077) | ₹9 each |
| Burnt clay brick, modular 190 × 90 × 90 mm | ₹10 each |
| Fly ash cement/lime brick, 225 × 100 × 60 mm, class 7.5 | ₹11 each |

| AAC block, 600 × 200 × 200 mm | ₹130 each |
| Shahabad or Tandur rough slab, up to 25 mm | ₹126 per sq m (about ₹12 per sq ft) |
| Shahabad or Tandur polished slab, 15 to 18 mm | ₹291 per sq m (about ₹27 per sq ft) |
| High-polished granite, 16 to 18 mm | ₹2,319 to ₹2,789 per sq m (about ₹215 to ₹259 per sq ft) |
| OPC 43/53 cement | ₹5,100 per tonne (about ₹255 per 50 kg bag) |
| PPC cement | ₹4,800 per tonne (about ₹240 per bag) |
| TMT steel, major makers | ₹56,000 per tonne |
| Screened sand for mortar and plaster | ₹1,023 per cu m |
Two SoR notes explain local quotes. Cement and steel rates are reset monthly by a sub-committee. And government estimates add 40% to labour in Greater Hyderabad, including a 12 km belt beyond corporation limits.
To check current prices, ask two or three local suppliers for written quotes that state the BIS grade, delivery and GST. Compare them with the latest SoR. For a whole-house budget, see the Hyderabad construction cost breakdown, and try MOA's home cost calculator. Who buys the materials depends on your contract type.
Mistakes to avoid
- Leaving the roof bare. A plain slab under a 40 °C sun heats the top floor all evening.
- Using the same wall on every side. The west wall needs better insulation or shade than the north wall.
- Skipping the soil test on black clay. A footing that suits granite can crack on expansive soil.
- Buying bricks or blocks without paperwork. Ask for the BIS licence and a dated test certificate.
- Polished stone in the wrong place. Polished limestone is slippery when wet. Use rough or honed slabs outdoors and on steps.
- Building before approval. Get permission first; the Hyderabad building permission guide explains BuildNow and Bhu Bharati.
FAQ
Which brick is best for house construction in Hyderabad?
Burnt clay and fly ash bricks are both sound if they meet IS 1077 or IS 12894. For west-facing walls, AAC keeps out far more heat: about 0.8 W/m²K against about 2.1 for brick, on BEE values.
What is the price of Tandur stone per sq ft in Hyderabad?
The Telangana SoR 2026-27 lists Shahabad or Tandur slabs at ₹126 per sq m rough (about ₹12 per sq ft) and ₹291 per sq m polished (about ₹27 per sq ft), before GST, transport and laying.
Is Hyderabad safe from earthquakes?
Hyderabad is in Seismic Zone II, the lowest zone in IS 1893 (Part 1). A structural engineer should still design and detail the RCC frame.
Do I need a special foundation in Hyderabad?
Usually not on granite or firm murram, but black clay pockets do occur around the city. Get a soil investigation before you design the footings.
